Good morning, lads! Today we see together the new speaker from Tronsmart, that is, the Mirtune C2. This model is positioned in an entry level market segment. The price is very aggressive, lower than the T7 Lite, but will the quality be up to par?

First of all, I wanted to thank Nora from Tronsmart.

I’m going to be as objective as possible, and being a common audio enthusiast, I will use simple words in this review.

I will highlight what I liked and what I didn’t, without any fear.

It is a very versatile BT speaker, and from the price, we can still consider it cheap.

I’m not going to use super technical words to review it, but I will do my best to describe it.

Tech Specs:​

• Model Mirtune C2
• Color Black
• Wireless Version 5.3
• Wireless Range Over 15m/49ft (open area)
• Input Power 5V/1A via Type-C Port
• Output 24W
• Microphone Built-in
• IP Rating IPX7
• Play Time (Varied by Volume Level & Audio Content) Up to 24 Hours (50% Volume)
• Charging Time 4 Hours
• Frequency Range 60Hz-20kHz
• Product Dimension φ72 x 184mm/φ2.83 x 7.24inch
• Product Weight 0.52kg/1.14lbs

Packaging:​

The packaging is as careful as on every Tronsmart product; however, this is a cheaper product. Inside, we find:

• Type-C Charging Cable
• Aux Cable
• Lanyard
• Warranty Card
• User Manual

We can say that the accessories are the basis for a similar product. The charging cable is a good one.

Design/Build Quality:​

In terms of design, we are faced with the classic speaker. On Amazon, you will find many that resemble it. At first glance, it seems like a T7 Lite with a slightly more minimal aesthetic but if you check better, you will realize that the passive radiators on the sides are smaller, which already makes you think of a less powerful product.


The product appears more anonymous; we do not find any brand in plain sight but only the logos on the radiators. In front, we have the buttons, which, as you will see, are fewer than those seen on the T7 Lite; in fact, this cannot be managed via the app. On the back, we have the usual cap to cover the charging input, aux input, and microSD reader. It is a complete portable speaker that can be paired with other identical speakers but has no other particular specifications. As regards the quality of the external materials, I think we can safely say that it is on par with the T7 lite.

The LEDs with the rhythm of the music work well and are of great effect. Too bad for the lack of DSP.

First configuration and test:​

The Bluetooth chip is always a customized 5.3 with much nicer prompts than the classic stock ones. Super fast connection and no stability issues.

I believe the Bluetooth chip is identical to the one present on other Tronsmart products, after the first pairing the connection is super fast. The only flaw is that stereo pairs can only be made between identical devices, therefore between two Mirtune C2 speakers but not with a T7 Lite.

Starting from the top, we find:

• On and off button + switching of LED games
• BT button to start pairing manually
• Volume up button / if held down – next song
• Volume down button / if held down – previous song

Equipment used for testing above

Device:​

• Redmi Note 7
• Poco M4 Pro

Software:​

• Amazon music UHD 24bit 96kHz
• Spotify

Sound impressions:​

Bearing in mind that this is a low-end economic product, I must first tell you that it should not have the starting price of the T7 Lite.


The motivation is immediately clear when you have both there. The sound, even if it is declared to be 24 watts like the T7 Lite, is absolutely not similar in power or equal in tuning. The Mirtune C2 aims for 360 degree sound so you will never have direct sound from both speakers at the same time but you will find a more dispersive sound. So you will actually never hear the alleged 24W, but always half, while the others will be dispersed in another direction. If you are indoors, obviously, the dispersion will be lower. But the real problem is that the quality of the drivers is certainly lower than that of the T7 Lite. I had noticed it from the size of the passive radiators and I had confirmation as soon as I started the test that their power was lower. Bass tends to be weaker and distort earlier.



The sound pressure, having the two speakers placed in different directions, is more complex to measure but certainly does not have the same impact in open spaces.


I would describe it as more balanced across the entire sound spectrum. The problem could also be cheaper amplification rather than the drivers themselves.


If kept indoors as in my test, the sound aiming for a 360 effect bounces off the walls giving good volume and quality. With powerful bass it tends to move because it doesn’t have a rubberized side. The T7 Lite in my opinion (perhaps you can also hear it from the video) has a much more crystalline and also more directional sound.

Fast comparison:​

vs TRONSMART T7 Lite


The Tronsmart T7 Lite is undoubtedly better than the Mirtune C2. Although, at first glance and after reading the specifications, they may appear identical to those less experienced, I can assure you that they are totally different. The absurd thing is that it is offered with the same starting price despite the clear difference. If it is a slightly cheaper product, it should not have the same starting price. The T7 lite also has the SoundPulse app and technology, which further improves the sound. I would have no doubts about which one to choose.

Conclusion:​

The Mirtune C2 is a reasonable product, but it should have a lower starting price, in my opinion, of around $29.99 USD, which can then be discounted further. I honestly don’t see the need for a similar product but in some countries, at the right price, it is certainly a product that will sell well. The sound in general is excellent but the 24 watts are, in my opinion, a little weak when compared to the T7 Lite, which has more or less the same specifications. Mirtune C2 got excellent battery life as usual, and LEDs work great. Having said that, given the price difference, I recommend you go for the other model.

At the price of around 25 USD, I think it is an excellent product. The market is very saturated with similar products and I believe that given how similar they all are in design, many people choose them for the promised wattage. Whether they are true or not, almost no one will notice, but I hope that Tronsmart will try to get closer and closer to JBL’s quality by experimenting with more drivers from more suppliers to find the best value for money.

The Letshuoer Cadenza 4 was sent to me as a review sample from Ivy from Letshourer, for which I’m grateful!


After the opportunity to try the S12 Pro, S15, and DZ4, I will finally tell you my opinion on the Letshuoer Cadenza 4.


The collaboration with Heygears continues; lately, Letshuoer shells are all produced by them. The aesthetics are always very minimal but I must say that the workmanship of the shells is still excellent.


Unlike the others, this is the first hybrid I’ve tried from Letshuoer so comparisons will be made with other brands.


I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music.


So I’m not going to use super technical words to review it, but I will do my best to describe it.

Tech Specs:​

Packaging:​

The packaging is the one we have already seen on the Letshuoer S15. It differs in very small details that are difficult to notice. It looks like a box of expensive jewelry or a beautiful watch. In the upper part of the box, we find a small letter with manuals and QC inside and immediately below the Cadenza 4, while in the drawer below there are the following accessories:

• Hard Case
• Adapters
• Cable
• Tips

If there’s one thing I like about the Letshuoer standard equipment, it’s the modular cable (even if it’s a bit stiff). The tips are carefully chosen and give you two options. The case is not the most comfortable but certainly one of the most resistant. The quantity and quality of accessories are good.

Design/Build quality:​

As you may have noticed, the Letshuoer Cadenza 4 follows the aesthetics of the DZ4 and S15. Letshuoer has been collaborating with 3D printing company HeyGears for a while now. The aesthetics are very minimal; they may not appeal to everyone, but I would like to say that on the aesthetic side, there are IEMs with superior aesthetics. In any case, the use of 3D printing allows you to create precise structures for the internal parts and probably also the tubing of the drivers. I’m not particularly interested in aesthetics but if I had to choose, it would be for the shells made from solid aluminium. The Letshuoer Cadenza 4 is still a nice sight. The faceplates are made of metal, which is very simple on the aesthetic side. We see that on the shell we only have one ventilation hole. The nozzle is massive and could annoy some but the shape is perfect as far as I’m concerned.


This time, the configuration is hybrid! We have a 10mm beryllium dynamic driver coupled with 3 balanced armatures. The first balanced armor is a Sonion, while the other 2 are Knowles. A decidedly interesting configuration already makes you understand why the price is a little high.

Comfort/Fit:​

As already mentioned, the shape of the shells is one of the best so far. The most classic forms are often the best and this proves the theory. They are very light and extremely comfortable. The original tips are both fine if you don’t want to replace them but I still used the Tangzu Sancai wide-bore ones. Decent insulation but not perfect.

Initial sound impression:​

At first listen, I noticed its medium-centric tendency. It’s not a bad thing but I noticed it immediately because I spent weeks with Simgot in my ears. I went from something with a certain brightness and definition to something that has a certain roll-off at high frequencies. It makes everything very safe and appealing to a wider audience.


It winks at the Harman target, rather than V-shaped, I would say it is W-shaped or U-shaped at times. The sound has a warm, lush note that is extremely pleasant. All in all, there is an excellent balance between all frequencies, with a slight preference for the mids. Everything sounds particularly natural; the sub-bass has a nice push that adds that depth that I like so much. Another very important thing is that it goes well with practically all musical genres.

Final sound impression:​

Equipment was used for the testing above.

Device:

• iMac
• Redmi Note 7 Snapdragon
• Poco M4 Pro Mediatek

Software:

• Amazon music UHD 24bit 96kHz (Both)
• Spotify

DAC:

• Moondrop Dawn Pro
• Fosi SK02
• Fiio KA11
• Fiio KA17
• Simgot Dew4x (Top synergy)
• iBasso DC04pro
• EPZ TP20 Pro
• Hidizs S9 Pro Plus
• EPZ TP50 (slightly less dew4x)
• Creative SoundBlaster X5 (slightly hot cirrus/Creative signature)

My first impressions after about 20 hours of burn-in, in which I let them play without listening to them, are that the Letshuoer Cadenza 4 is a very interesting set and certainly, given the tuning chosen, many will like it. Furthermore, she goes with different musical genres. I started from EDM, D&B, R&B, Jazz, classical, and rap, and there isn’t a single genre in which I wasn’t surprised with the performance.


Letshuoer has created a good mix while remaining on the safe side. In terms of Dac/Dongle, you don’t need an exaggerated amount of power to drive them at their best but a good dongle with balanced output certainly helps them considerably. If you have something analytical and neutral, even better! Its slightly warm nature is mitigated by analytics dongles such as the EPZ TP50, Fosi DS2 or Fosi SK02. The synergy it has with the Simgot DEW4X is particular, which presents a superior soundstage. Personally, I think it is the combination that I like the most and that I will continue to use for the review.

Tips Rolling?​

Tips Rolling

An upgrade of the tips is not strictly necessary but the Tangzu Sancai Wide Bore had just arrived and I thought I’d try them. The nozzle practically comes to be totally free in your ear, avoiding reductions in soundstage. Excellent combo.


The Divinus velvets, as usual, prove to be universal; every headset you mount them on will give you the perfect seal and improved comfort. In terms of sound, I didn’t notice an exaggerated change from the stock balanced tips. Maybe less bass.


The Dunu S&S I didn’t think they could be suitable for the Cadenza 4 and instead I had to change my mind. They move the IEM away from the ear a little but we remain in our comfort zone. The difference compared to the Tangzu is a slightly less full bass, brighter mids and slightly more refined highs. Obviously, the soundstage is wider and I can tell you that all in all, it has an excellent result if you are willing to sacrifice a bit of bass.


In my opinion, the included SS20 similar tips are exceptional, even the others are not bad at all for being stock. You don’t need a real upgrade but if you have some tips rolling at home, it never hurts.

Bass​

I must say that with the Tangzu wide bore tips, the basses have a very pleasant level up, the sealing obtained is perfect, andthe insertion is also quite deep. The bass quantity is not high, but the 10 mm single DD returns a rich, warm, and textured bass. Let’s be clear: it’s not at a basshead level but it still makes itself felt. The one that is properly emphasized is the sub-bass, which adds the rumble and the right rich and deep vibration. Honestly, very pleasant bass in the quantity that I would have liked to hear on the Simgot. A slight emphasis, without exaggerating, is an excellent combination with the mids.

Mids​

The mids are the real protagonists of Letshuoer Cadenza 4. They present themselves ahead of everything, making the vocals and instruments alive and rich in detail. Track after track, we become more and more sympathetic to this kind of choice. A silky representation of the voices, which are all extremely exciting, the instruments are particularly well sounding and natural. I only notice a very light nasal note and a very small haze on some tracks. Let’s say that it isn’t noticeable that much and perhaps it is precisely this touch that gives a certain warmth and sense of reality to the voices. The precise separation of frequencies here becomes much clearer, the tubing of the drivers is well done, and the sounds are all in their place without invading regions that do not belong to them. What is perhaps missing is a slight extra sparkle on the highs, which causes some detail to be lost.

Treble​

As I already said, they didn’t exaggerate with treble extension. I can say that the choice certainly makes sense since many do not tolerate these frequencies very much, but those who tolerate them will certainly notice that some details are lost. Fortunately, the loss is not high and the highs are very fluid with good resolution, as they are not extremely high you cannot hear sharp highs. The IEM can be pushed at high volumes without reaching annoying peaks. The separation is excellent but for trebleheads, it could be considered warm and calm, even if, in the end, there is a good presence of macro and micro details. A touch more sparkle would have been perfect, however, there are DAC combinations that solve this situation slightly.

Soundstage and Imaging:​

Letshuoer Cadenza 4 doesn’t reach the levels of the Letshuoer S15 but I can tell you that the result is excellent. The driver tubing and precise tuning maintain excellent sound separation which contributes to a wide soundstage with good depth. Each sound arrives at the eardrum clear and perfectly distinct from another. Following every little nuance of the track you are listening to is very simple. Good job!

LETSHUOER Nebula Cable Upgrade:​

Nebula Cable & Earhook
If you expect a difference between day and night, then know that this is not the case. However, against all expectations, despite being a copper cable (which usually increases the bass), here we have a very strange increase in brightness. I say strange because I doubted I would notice any differences, especially regarding the high frequencies, somehow like a sprinkling of stardust on the already excellent Lethshuoer Cadenza 4. Somehow it makes them extremely attractive, starting from the mids, which lose the very light note of warmth or nasality they had. With this upgrade, the Letshuoer Cadenza 4 seems much less mid-centric, giving a superior balance between all frequencies.


I’m very much for the placebo effect, it’s almost inevitable that our brain comes into play. There is a bit of self-conviction that the new cable is better than the old one. In any case, if there were large variations in sound it means that one of the two cables was made of non-conductive material. I am also passionate about audio systems and speakers and have already suffered from cable disease. Now I feel better and as long as we’re talking about pure copper everything is fine.


Without bench tests with measurements, my words stop at personal sensations.

Comparison:​

vs Letshuoer S15


If you prefer the bass of the DD, the Letshuoer S15 will probably not be considered. The almost $100 higher price makes them fit into a totally different budget. There are those who consider them one of the best planar IEMs to date but they have opponents like the Hidizs MP145 who question their price. What I can tell you is that the planar presents many more macro and micro details and the soundstage develops in a wider and more precise way. Personally, I prefer the bass of the Cadenza 4 but on everything else, the planar driver has a superior and more immersive performance. The rumors about Cadenza 4 are slightly better but both are very attractive.

vs Simgot EM6L​

Simgot EM6L
A much cheaper hybrid IEM from Simgot. One of the best examples of a successful hybrid in a price range where others have failed to achieve great results. Every time I wear them, I am surprised, even though the driver configuration does not include BA from Sonion or Knowles. Its sound is full of energy and the tuning is also suitable for gaming as it is very precise on details. The Simgot EM6L, although successful, does not keep up with the brand new Candeza in terms of technicalities.

vs Simgot EA1000​

Simgot EA1000
The Simgot EA1000 but also the EA500LM allow you to ask yourself the following question: “Do we really need more drivers?”


Honestly, in the case of the EA1000, the answer is that no other drivers are needed. This is not a rule but Simgot has demonstrated that it is possible with a single driver to obtain something extremely close to what we can define as high fidelity, both in terms of performance and timbre. I consider them a point of reference for those looking for something that sounds extremely faithful.


vs Hidizs MS5

Hidizs MS5
The MS5 are the IEMs that decided to start the reviews. A sort of first love. A fairly extreme hybrid IEM from Hidizs with a purely V-shape nature with borderline highs, if you are sensitive, these are absolutely not for you. They go far beyond the brilliance you can experience on Simgot. In terms of bass, they are more present and emphasized. my favorite nozzle is obviously red. The others are too much, even for me. At the detail level, the macro and micro details are more highlighted.


But its biggest flaw is that it is not an IEM suitable for any musical genre. In terms of results, the Letshuoer Cadenza 4 is superior,in my opinion.


vs Hidizs MS3

Hidizs MS3
I consider the Hidizs MS3 to be an excellent rival, typically more V-shaped, providing a much more robust bass and livelier highs. Sometimes they could be at the limit but I’m on balanced cable, and they are more contained than the MS5, giving that touch of brilliance that is kept more controlled on the Cadenza 4. Depending on what you are looking for, they could be an excellent alternative.

Conclusion:​

Undoubtedly, Letshuoer has managed to make an extremely exciting hybrid IEM, and the Nebula cable is certainly an appreciable upgrade. Also keep in mind the importance of the eartips and, above all, the DAC with which they are combined. In my opinion, the Simgot DEW4X is the one that has the best synergy of all.


The Letshuoer Cadenza 4, aesthetically, is simple but sturdy; the design may not appeal to everyone but the HeyGears shell is of excellent workmanship. Comfort is optimal and being light, they do not cause any problems of heaviness even after several hours of listening. On long listening sessions, it does not cause any kind of problem or annoyance, whatever genre of music and listening volume you choose. I can’t say the same thing about the Hidizs MS5, on which the volume I can tolerate depends a lot on the track; the highs literally bite the eardrum despite some extra detail. I really liked it, one of the best hybrids so far.

The brand new Letshuoer Nebula cable, It is a cable that I personally define as premium and, of course, expensive, and I struggle to talk about it without a bit of skepticism. I am not one of the “skeptical cable users,” and I usually purchase a cable to improve functionality or aesthetics.
Seeing the declared strengths, it makes you think of a cable made with extreme care that has very high conductivity. Cable, connectors, and soldering are theoretically superior, but I certainly have no way of verifying this. In-depth laboratory tests are needed and as I had already informed myself, someone had tried to compare cheap cables with expensive cables and the result was not obvious. I usually go for copper cables that range from 20 to 30 dollars so reviewing one for 160 and recommending it to you without a shadow of a doubt is not for me.

Tech Specs/Strong points :​

Strong Points

Packaging & Aesthetics:​

UnboxingFirst lookUnboxed
It arrives at your house in a package that could contain an IEM; it comes in a rigid case similar to the Cadenza 4. At first glance, I can not say I was surprised by its construction. From a distance, it resembles a CCA or KZ cable. I admit it is not a compliment, but I challenge anyone who looks at them in passing not to notice a strikingly similar strain.


NebulaEarhookOn hand
The difference is in the cable’s quality, which should be made of very pure 6N OCC Taiwanese copper, with gold-plated connectors and professional silver welding. All of this is based on trust, as I lack the technical skills to argue otherwise.

Splitter4.4mmPinsUltra macro6N OCC copper0.08mm strains
The earhooks, on the other hand, are a little unusual; instead of the standard shape, they wanted to make it customizable by inserting a soft steel core, which, in my opinion, should have been longer. It is difficult to shape it correctly, so it may feel more uncomfortable at first than the standard cable. Another thing that perplexes me is that it is not modular like the standard one, which would have been ideal for the requested price. You can choose between 3.5mm and 4.4mm jacks.You can choose between 3.5mm and 4.4mm jacks.

Honest premise:​

I start with the premise that some measurements should be made, which I have no way of doing.


Talking about it freely is not the most correct method to demonstrate that the cable is worth the cost. Materially and aesthetically, you have already been able to see from the photos that it is not the thick cable that one would have expected. The thick cables ultimately serve no purpose other than adding weight but perhaps a little thicker wouldn’t have been a bad thing.


Since it came with Cadenza 4, I decided to try it with these.

Does it affect the sound?​

Despite the fact that this is a copper cable, which usually boosts the bass, there is a surprising increase in brightness. It is like a sprinkling of stardust on the already excellent Lethshuoer Cadenza 4. This makes the high frequencies even more appealing.

On the Letshuoer S15, however, the differences are lower than expected. I don’t feel a huge change; perhaps the enthusiasm is dampened by the lost comfort due to the earhooks.

Considerations and costs:​

160 USD of cable is not a small amount. Many people cannot spend that amount on a similar product. I am part of this category of people. There are even more expensive cables but this is already an important price for me. For the same price, I got my old Redmi Note 7.


I was surprised to hear an improvement in the sound; I did not expect to hear anything different. The earhooks, in my opinion, are the biggest flaw; they are not exactly universal and plug-and-play.


They must be reshaped based on the IEMs used. The Letshuoers S15 lacks comfort, and even when they are reshaped, the positioning is not quick or easy.


Cables, like eartips, are not universal; some pairings work better than others.


The same rule applies to the Letshuoer Nebula, which is undoubtedly a good cable, but you cannot pair it with 40 USD IEMs. From my point of view, we need an IEM that costs at least as much as the Cadenza 4, and we are still at the limit in terms of the IEM/cable ratio. Another thing to consider is how many bends the earhooks can withstand and how many pins can be inserted. I usually avoid cable rolling for fear of loosening the IEM pins.


To summarize, if I had the money, I would definitely buy cables similar to or better than the Letshuoer Nebula, but for the time being, I am using my savings to purchase other IEMs or Dac/AMPs. Despite its thin and simple appearance, the Nebula is likely made of high-quality materials. I am hoping for a future modular version, perhaps even at a lower price.

P.S. The placebo effect on cables is a factor to take into consideration, our brain convinces itself of the improvement but the reality is that bench tests should be carried out with scientific and precise measurements to establish an actual improvement. Having said that, this is more of a presentation than a review.

Disclaimer:​

Good morning, Readers! Today we will go over the Simgot EA1000 Fermat. I eventually made it to the top after starting with the EM6L, EW200, and EA500LM.


Even though it’s not exactly a single driver, I feel like comparing it to other similar IEMs. Simgot wanted to add a passive radiator to the EA1000 in order to achieve the desired result, but because it is passive, it cannot be considered a driver.


If you are sensitive to sparkling and slightly spicy highs, these are not for you, just like the EW200 and EA500LM.


I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music. I fall into the audio enthusiast category.


So I’m not going to use super-technical words to review it, but I will do my best to describe it.

Tech Specs:​

• Driver: Second generation DMDC 10mm dual-magnet & dual-cavity dynamic driver + 6mm PR
• Diaphragm: Purple-gold dome diaphragm
• Impedance: 16Ω±15%(@1kHz)
• Sensitivity: 127dB/Vrms Frequency response range: 10Hz–50kHz
• Effective frequency response: 20 Hz–20 kHz
• Connector: 0.78mm 2-pin
• Cable material: high-purity silver-Plated OFC Litz Structure
• Price: 260 USD more or less

Packaging:​

The packaging of the Simgot EA1000 Fermat represents a clear improvement, and considering its price, it seems correct that it stands out for class. Aesthetically less mystical but with a tribute to the mathematician named Pierre de Fermat, I don’t think there is a particular correlation; simply, the result obtained by the EA1000 is the result of precise calculations.

Accessorie boxes
Once the package is opened, we find the tribute to Fermat, and underneath the IEMs are the following accessories:

• Hard case
• Nozzle with base
• Nozzle o-rings
• 6 pairs of tips
• Litz cable
• Manual and QC

Obviously, the packaging is richer and reflects the price at which the product is positioned quite well. The hard case is finally not anonymous but has the Simgot logo above and a phrase below. The tips are the standard 07; I am not sure why they included two identical sets, but the cable is noticeably better than the one used on previous models. The nozzles arrive on an aluminum base rather than in a plastic bag, and I noticed a small error in the writing engraved on the base, which reads “Salu” rather than “Salute”. I could not tell whether it was a problem with the machine or an error in the file. I do not think it is anything serious, but I would prefer not to see control issues on a similar product.

Design/Build Quality:​

The Simgot EA1000 Fermat is the closest thing to a jewel; the aesthetics, and especially the materials and color choices, evoke jewelry. This choice may not appeal to everyone, but I do not see any issues, and I do not believe I am losing masculinity by wearing the Simgot EA1000.


In terms of shapes, we are more or less the same as those seen with the EA500LM, quite natural shapes that shouldn’t cause problems of any kind. In the internal opening, we have 3 ventilation holes, one of which is really large. On the outside, the faces appear to be made of glass, which is aesthetically very elegant with a rose gold or copper-colored edge. What I can notice is that the shells are not exactly very light; I think they are obtained from a metal fusion and then CNC machining.


The Kefine Delci, on the other hand, have a machined aluminum shell and are much lighter, undoubtedly with a higher quality shell. I hope to see a Simgot with a similar shell in the future. As for the ventilation holes, I can venture that the small ones are for the DD while the larger one is for the passive radiator, assuming that it is truly an opening and not just something aesthetic.

Initial sound impression:​

What I noticed as soon as I put on the Simgot EA1000 was the tuning, which corresponds exactly to what I expected, but what is surprising is the timbre, which has a devastating naturalness. I don’t know if there are IEMs with a more correct tone but this really seems to me very close to what something natural should be. The driver, despite the same technology as the EA500LM, has a totally different material dome, which should be more rigid. I can tell you that it has a very high resolution and the transitions are lightning fast.



Harman tuning follows and using the nozzles, you can try more variations even if a couple are very similar to each other. The mids, on the other hand, could be a bit shouty at times, but fortunately, 98% of the time, this is kept under control. The medium is vivid and detailed with a very high resolution. What is surprising is the timbre of the voices, which is extremely pleasant and natural (they also have the right thickness). Then there is the instrumental part, where guitars and cymbals are extremely real thanks to the vibrations that have. The treble could be high for those sensitive to high frequencies, but the reality is that they are extremely crisp and smooth and make their representation rich in macro- and micro-details with a large presence of air; they have that touch of crystalline and transparent.

Tips Rolling?​

Tips Rolling

Depending on what nozzle and source are used, you may want to slightly adjust the sound with different tips. It is needless to say that the BGVP 07 tips are excellent but you can certainly try models with higher quality too.


I currently tried the TRI Clarion, which has excellent comfort but made me slightly lose something in the low range.


The Kbear SS20, on the other hand, has an excellent balance between Stage and the other frequencies, but it appears that I have lost something in the bass. In this case, I switched to the gold-colored nozzle, and everything seems to be great again.


I decided to try the KZ Starlines, and to my surprise, they provide incredible comfort while slightly reducing the sharpness of the high frequencies, giving the body a lower range. Surprisingly, they appear to be very good, but I seem to have lost some definition.


Honestly, using tips like Starline on a similar product doesn’t make sense so I continued with the tests.


I thought the Dunu S&S were not comfortable on this model; I had to change my mind but I think they give a bit of a concert hall effect. I don’t particularly like them.


The Divinus Velvet, on the other hand, has excellent comfort but I usually use it where I need to reduce the pressure in the ear canal and in the case of the Simgot EA1000, there are no important pressures to eliminate. Reduces low frequencies a bit.


The BGVP 08, on the other hand, surprisingly resembles the KZ starlines; the shape varies very little but what they have in common most is the structure that surrounds the nozzle. I have come to the conclusion that, compared to wide bore tips, narrow bore tips are slightly more suitable. However, you sacrifice a bit of soundstage so as a final balance, the SS20 tips are the ones I decided to use for the review.

Comfort & Fit:​

For comfort, I feel like recycling the same thing I wrote for the EA500LM:


“As far as comfort is concerned, the shell has the right shape. The only sore point could be their weight; if, by chance, you have a particular shape of the ear, it could create pressure points. Usually, with the right tips, you can solve these problems.”


Fit with SS20

Nozzle:​

Gold White:

On the EA500LM, I was certain that this was the best nozzle; on the EA1000, the question is slightly different. As you can see from the photos, the silver nozzle with the red o-ring appears to be the most free of them all. The gold one has a fabric filter with a hole in the middle. I believe it affects both treble and bass, while also slightly smoothing up midrange perception. My main concern is that limiting the freedom of sound output so drastically will compress the stage slightly. I was wrong because, in reality, after thinking about it, this is the nozzle, which has a central part completely free of filters. The sound has a greater sense of harmony and balance, as well as being more holographic.

Silver Red:

It suppresses the holographic image a bit, but in reality, the nozzles are also made of different materials; the gold one is like brass, which could also oxidize, while the other does not. In my opinion, the material also has little influence. The positioning of the various sounds with the gold nozzle seems much more precise to me.

Silver black:

I wonder if this nozzle really makes sense, as I feel very little difference from the silver red. Despite the presence of the foam, there are very few changes to the trebles, which are slightly more docile (they would need a higher density) and the sub-bass, which seems slightly fuller.

I didn’t notice any differences after burning it for a few hours. They sound great right out of the box.

PR Vent
As previously said, I continued the review with the Kbear SS20 tips. Certainly, the driver, although similar to that of the EA500LM, has a totally different dome. In addition to that, there is the configuration of the single driver combined with the passive driver. Reading among the specifications, the larger ventilation hole corresponds to the passive driver, and the internal driver has a closed cavity that communicates with this passive driver, which has an external vent.


In fact, this “driver,” which is more of a membrane, resonates alongside the main driver, aiding in frequency response, particularly in the low range. It is difficult to demonstrate how and if it has an impact, so I will refrain from going into detail and relying on assumptions. What I can say is that the bass reverb has a distinct definition that I did not experience on the Letshuoers DZ4.


Simgot’s sound timbre is undeniably distinctive. In fact, I could describe them exactly like the EA500LM, though the driver is far more refined in his presentation of every detail.


The tonality in the midrange is slightly more coherent than that of the EA500LM, and I do not notice the slightly cold touch to the voices. The highs, on the other hand, are much more detailed, but they also have a lot of separation and airiness.

Bass​

In terms of bass, we are absolutely not at basshead level but the quality is extremely good. There is a clean bass and a slight emphasis on the sub-bass without deviating from the naturalness of the tuning. The bass is precise, fast, and rich in texture, just the way I like it. Compared to the EA500LM, the quantity seems very similar to me but the quality is slightly different, probably the rumble has more thickness due to the passive radiato. It seems to have more control.


No track will emphasize bass or sub-bass rumble beyond the “natural” threshold.

Mids​

It’s been a while since I heard such interesting mids; even though they should be recessed, I hear them at the forefront with the other frequencies. A lot of upper-midrange energy might be a little warm for some of you but I assure you that if you have no problems, you will be rewarded with super silky and luxurious female voices. On the lean, you could have used a touch of extra warmth but honestly, you just need to have the headphones with something similar to the Hidizs S9 Pro Plus.


As far as musical instruments are concerned, extension and separation help the instruments maintain their naturalness. The male voices are slightly less pleasant and are also less forward than the female ones. It could simply be because of my preferences!

Treble​

With airy and open high frequencies, the amount of detail that overwhelms you, leads you to believe that there are other drivers at work, but the reality is that the tuning and driver have worked wonders. Air and sparkles can be appreciated track by track, but if you are particularly sensitive, they may bother you. Despite this, compared to the EA500LM, I noticed fewer tracks that were too hot or harsh. A treble extension that does not make me miss anything from the songs.


Because it is brighter than other IEMs, it is obviously more difficult to achieve high sound pressures (the Hidizs MP145 are more tolerable at high volume), but if you plan to push, you should consider switching to foam tips.

Soundstage and Imaging:​

In my opinion, the Simgot EA1000 soundstage is superior to the EA500LM (not exaggerated but there is a certain concert hall effect in certain tracks), but what makes the biggest difference is the precision of the image, in which each sound seems to have a fixed and precise track that reaches your eardrum without crossing any other sound. You will notice that each instrument and the voices are totally separate. The layering is also excellent.

Comparison:​

The price of the Simgot EA1000 Fermat becomes spicy, we are no longer in the territory considered economical but more in a medium/high price based on who is reading the review. If we consider the prices of audio products, it is not an astronomical sum. In this price range, planar drivers also come into play.


vs Simgot EA500LM


Simgot EA500LM

Some people prefer the Simgot EA500LM over the Simgot EA1000, so who am I to tell you which one to buy? Yes, I am nobody! As far as I’m concerned, the resolution is on another level, the difference is certainly more marked than the EW200 and the EA500LM. There is a difference but the tuning and sound signature are the same so unless you are so attentive to detail, you can easily stop at these. Furthermore, if you don’t have both, you can’t say which one is better. Are you ready to shell out 400 USD?


vs Hidizs MP145


Hidizs Mp145

The Hidizs MP145 were a huge success, and I do not believe there has ever been a more popular planar IEM. In terms of detail and high frequency extension, the EA1000 outperforms them. The Hidizs MP145 have decidedly warmer tuning and a much more present bass; they can be pushed to higher volumes without issue, and you will not be flooded with too spicy highs. The soundstage, on the other hand, is one of the largest ever, and the planars excel in this area. Both are constructed with high quality materials. It is undoubtedly more appealing to the majority of people. The shell is very large and is not comfortable for everyone.

Conclusion:​

Simgot EA1000 + SS20

I have no doubts that the Simgot EA1000 Fermat are excellent IEMs. I am aware that these are IEMs that a newcomer to the hobby would be unlikely to purchase, but I am confident that many in the audio industry will appreciate them. The target users are those who enjoy high fidelity; recording must be as close to reproduction as possible, and in this case, I believe there is nothing to improve, at least in terms of sound quality.


In terms of personal preferences, I would have preferred more bass presence. However, the Simgot tuners know what they are doing in terms of sound, and an audio enthusiast like me has no right to criticize their work. In addition to the sound, they got the aesthetics right; it is very elegant and solid, and the accessories are adequate, but I would use two different types of tips in future.


If the brilliance does not knock you out, you will be rewarded with an IEM that takes you through track after track, providing details, sparkles, and resolution of a completely different kind.

Disclaimer:
Good morning, readers! This time, I received a product from FX-AUDIO, a brand that somehow introduced me to this hobby. My first product, or rather, the first desktop DAC that I purchased years ago, was the FX-AUDIO X6. It cost just over $50 and was considered a miracle. It was difficult to explain such a price, but those who owned the first models and had the opportunity to look inside for some OP-amp upgrades know that the components were recycled (second third life) and the welds were completed quickly. Surprisingly, it worked especially well; subsequent versions were much more precise in their soldering.
I also tried the Tube 01, which is a type of tube buffer pre-amp, but it is no longer in use.
After several years, FX-AUDIO finally releases a new model, which obviously piqued my interest.
Despite having a lot of Dongles, I did not have many Desktop DACs and DAPs, but I will try to conduct a thorough analysis.
The review, as always, will be completely unbiased, uninfluenced and free of affiliate links
I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.
My opinions are obviously subjective.


Tech Specs:


For convenience, I have taken the specifications from the manufacturer's website, which, however, omits some specifications that may be of interest to those who purchase it.
To recover some information, I had to take it apart.
In the manual, there is information missing from various sites and the only extra thing I couldn't find is the OPA1656. But in its place, I found the following:
Upgradeable dual OP-amp: LM4562NA
For the headphones section, I found a TPA6120A2 and I found an AKM4118, which is responsible for OPT and COAX inputs.

Packaging:

For me, who has already bought FX-AUDIO products, the packaging is nothing new. The box is all white and very anonymous; it looks like a pre-release product with a box that is not totally definitive but I don't think there will be any changes.
At first glance, I noticed the Hi-Res logo had a slightly "copied" appearance.
Inside, we can find:

• Power supply: 12V/2A
• BT antenna
• Remote
• USB cable
• Manual

The product is carefully packaged, the accessories are of high quality, and the USB cable appears to be from another brand, but I replaced it (there is no change in sound, only in appearance). Perhaps an optical cable could have been included.

Build Quality/First Impressions:
Having previously handled their products, I can assure you that the quality has always been high in comparison to the price, albeit not perfect. In my unit, I noticed that the volume knob was not perfectly aligned. When I disassembled it, I discovered a somewhat artisanal shim inside where the pin is housed to keep the knob from touching the chassis. On one side, there are two micromarks where the paint has worn off.

Let us assume that quality control can be improved further. The front panel includes a physical on and off button, as well as 3.5mm and 6.35mm inputs; however, there is no balanced output. The volume knob is also used for other functions that make the remote control more useful.

Behind, however, we really have a lot of inputs, even though personally, I almost always use the USB input but in reality, it is a much more versatile product.
In terms of size, it is much larger than the old Fx-Audio X6, and it also warms up significantly more in use. Out of curiosity and to discover its secrets, I opened it. I can tell you that the PCB is quite clean and decidedly more refined than in the past. There are still some traces of flux but otherwise, the soldering seems well done.

I forgot to talk about the small display; some details need to be significantly closer to be readable. I must admit that it looks a lot like the display that could be used on a Dongle. It still fulfills its function.


Configuration:

The FX-AUDIO DR07 replaced the old X6 on my desk. The outputs that I will currently use are the RCA ones with which I enter a Breeze Audio (BRZ hifi) TPA3116 amplifier, which is now a few years old but does its job perfectly. It is not the chain for absolute Hifi quality but one of the cheapest that could be put together a few years ago. As speakers, there are a pair of Scythe Kro Craft Rev. B. For those who know them, you will know very well that they are not perfect at all but for 50 USD per pair, they are absolutely crazy. The only flaw is the tweeter is a little too cut; he seems shy and too directional.
The USB cable is custom, short, and "hi-fi" but it significantly reduces tangles. The original one is fine but too long for my purpose.

Let me start by saying that they are not high quality speakers but compared to the X6, I noticed a much better sound. I would have liked the tone controls but unfortunately, they cannot be adjusted. The sound appeared clearer and above all, the highs came to life slightly. Operation via remote control is the most welcome thing ever. By now, I have gotten used to some products with remote control and volume control is a must have. Fortunately, you can also adjust a few settings, such as manually selecting the input, selecting whether to leave the output automatically (if you insert headphones, the RCA outputs are deactivated) or in ALL, where both remain active.

As on the old model, when it goes into play/pause, there is a sort of "click," but honestly, it doesn't cause me any annoyance or problems. I think the outputs are disconnected to avoid background noise.


Digital Filters & Sound Signature:
There are some digital filters available; in total, there are 6:

1. Short Delay Sharp Roll Off
2. Short Delay Slow Roll Off
3. Sharp Roll-off
4. Slow Roll-off
5. Super Slow Roll off
6. Low dispersion, Short Delay

The changes are extremely minimal; the slightly greater difference is felt from the sixth to the first filter. I'm happy there are some functions but unfortunately, most of the buttons on the remote control have no functions. But those who have other products considered CHI-FI know that it is not difficult to see the same things on even higher-end products.

Sound Signature & Power:
The sound of the FX-AUDIO DR07 is almost neutral from both speakers and headphones. To be extremely honest, I don't think it was created to replace any headphone DAC/AMP. It doesn't impress with almost any headphones or IEMs in particular. It's not that it sounds bad but I have dongles that definitely sound better with more synergy. The thing I noticed right away is that with extremely sensitive and efficient IEMs, there is background noise and the only way to eliminate it is to use an impedance adapter. The noise is like a hiss that is heard at very low volume settings, with quiet, relaxed songs and between songs. The absolutely strange thing is that I haven't found anyone complaining about this problem. They could have tested it with only some high impedance headphones..1100 mw at 32 ohm are not very few and if the background is not very silent, you risk hearing this noise.

To exclude other problems, I started with the power supply, trying to use a different power supply with an extra 1A without success. I changed the USB cable and socket but the noise is still there.
This noise is not particularly audible, but the FX AUDIO DR07 is not suitable for headphones or low impedance IEMs.
I tested the Hifiman He400Se, Re-9, Sundara Close back, Philips Fidelio X2HR without experiencing significant background noise. I recommend keeping the gain low which is more than enough for most of my headphones.
I think it's right to point this out because it's not as universal as others with similar power. I think the background is actually not as silent as it seems. It was a different story for the RCA outputs, where I couldn't hear any kind of problem but the Scythe speakers are not very sensitive and could muffle the problem.
I noticed that after a few hours of use, it reaches quite warm temperatures, I think it depends on the listening volume but as there are no air vents, it could also heat up slowly and gradually.


Fast Comparison:

vs FX-AUDIO X6
You never forget your first love, I have to tell you that the first model was assembled in an unprofessional way, the parts were recycled and some components were rusty, it worked and it was a miracle. After several years, it failed, probably due to a mistake on my part in handling it while doing some OP amp rolling. I bought it again immediately and the new one was made with much more care and much better components. It was an excellent entrylevel DAC/AMP and still does its job. I will definitely use it on another PC. The DR07 pretty much covers all the gaps the X6 had by adopting better components and extra features. In terms of sound, the X6 seems slightly warmer to me, while the DR07 is super neutral. I don't feel like saying that great improvements have been made in terms of headphone amplification.

vs SMSL Sanskrit 10th
My Sanskrit works well but despite the slightly more renowned brand, I had to return the first unit as it created artifacts in the sound. I must say that it works very well connected to the Hivi Swans T200C but it does not have BT or headphone output. Also, in this case, the remote control has many buttons without functions. Aesthetically but also in terms of finish, it is slightly better. They are two products for a different target but if you are not interested in the headphone output, I recommend you keep that in mind.

vs Creative Soundblaster X5
The full review of this product will arrive soon. A sort of mix between desktop DAC/AMP and headphone amplifier with an eye also on gaming. In addition to having a balanced 4.4mm output, it also has a microphone input. A lot of functions are available via apps on your smartphone or software on your PC. We can create custom EQs, update firmware, and much more. Its versatility is superior, as is the price, but the product is infinitely more refined. The sound is slightly warm, in a Creative sound style. It resembles the Creative Sfxi AMP Dongle.


Conclusions:

Definitely a versatile product but not perfect as described by several reviewers. If you are looking for a DAC for your speakers, it is certainly very comfortable and works very well, but if you are also interested in listening with headphones or IEMS, you should know that it is not suitable for everyone. Leaving aside the background noise, I wasn't thrilled with any headphones I used; I didn't find any particular synergies. I could probably try replacing the OP-amps and see if I notice any improvement. It is absolutely perfect for what I intend to use it for, and it is far superior to the old X6.
FX-Audio is a brand with potential, I hope in the future they concentrate more on the QC which is often left out of even much more important brands. On the next I would like to see a balanced output and a slightly larger display.

Disclaimer:​

Good morning, readers! I finally had time to review the Simgot EA500LM. I confirm that all Simgot products follow a certain tuning style that I really like. Their tuners know their own! Musically full of energy, they stand out from the crowd and they honestly seem to be one better than the other. There isn’t an IEM of theirs that I haven’t liked so far. I have yet to review the Simgot EA1000, which will be the next review to be published.


What I like about Simgot is that they take great care of the aesthetics of the product, starting from the packaging, passing through the aesthetics of the product without forgetting the sound, and giving very good tuning. If you are sensitive to trebles, these may be too much for you.


I thank Simgot for sending me this sample so I could review it.


I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music.


So I’m not going to use super-technical words to review it, but I will do my best to describe it.

Tech Specs:​

• Driver: Second generation 10mm dual-magnet & dual-cavity dynamic driver
• Diaphragm: The second-generation lithium-magnesium dome diaphragm integrates with flexible suspension
• Impedance: 21Ω±15% (at 1kHz)
• Sensitivity: 123dB/Vrms at 1kHz Gold Copper nozzle & Red Silicone Ring) / 123dB/Vrms at 1kHz Silver Steel nozzle & Red Silicone Ring) / 124dB/Vrms at 1kHz Silver Steel nozzle & Black Silicone Ring)
• Frequency response range: 10Hz–50kHz
• Effective frequency response: 20 Hz–20 kHz
• Connector: 0.78mm 2-pin
• Cable material: high-purity silver-plated OFC cable

Packaging:​

The Simgot EA500LM box is mystical, especially at certain angles, with the sun’s rays dazzling you with rainbow reflections.



A package capable of attracting anyone’s attention. Opening the package, we immediately find the Simgot EA500LM as beautiful as two jewels. Inside, we find 2 boxes with the accessories inside:

• Nozzles
• Tips
• Hard case
• Cable
• Manual and QC card.

The cable is identical to that found in the Simgot EM6L; it is not particularly attractive, but it is a good stock cable that is flexible and lightweight. The tips are the “07” type, which often works well with all IEMs and is the best you can find already included in the package. The hard case is similar to the one seen on the EM6L, but a little anonymous; it is not a big deal, but I would have added a nice Simgot logo.

Design/Build Quality:​

For my personal preferences, these fully represent my aesthetic taste. Maybe they are too minimal but the metal shell with mirror finish is absolutely fantastic. We have the possibility to choose 3 different nozzles (a choice that I prefer compared to the switches that I hate), the faceplates are simple with the Simgot and LM logo, and on the inside we find two ventilation holes.


The nozzles are quite large so they might bother some of you. Like various chrome products, obviously dirt but above all, skin sebum sticks to the surfaces. I note that unlike some recent IEMs such as the Kefine Delci, the shell of the Simgot EA500LM is probably obtained from a fusion and is therefore heavier. I hope in the future they will also arrive with a model with a shell machined from solid aluminium using CNC machining.

Initial sound impression:​

At first listen, I wasn’t particularly surprised due to the stock tips, which, despite being good for most of the IEMs on the market, this time didn’t get along with my ears. After changing tips, I immediately appreciated what I was listening to. I would have liked to make a comparison with the EA500, but from what I saw graphically, I believe that the EA500LM is a revisitation with more bass, sub-bass, and treble.


Everything remains very balanced, in my opinion, and even if it winks at the V-shape at times, it resembles more of a W-shape. You immediately notice how Simgot always has a certain sound signature on its products. I can feel that they are all from the same brand. The Simgot EA500LM has somehow merged the treble of the EW200 (further improving it) with the rest of the older EA500, where they have added more bass. The overall mix immediately seemed rich in detail, with a precise image but a quite intimate soundstage. IEMs are also suitable for gaming but currently the best in this area remains the EM6L. I think I’ll look for a balanced cable to match it.

Comfort & Fit:​

In terms of comfort, the shell is the ideal shape. The only drawback could be their weight; if you have a unique ear shape, this could cause pressure points. Typically, with the right eartips, you can solve these issues.

Tips Rolling?​

I believe it is one of the IEMs most sensitive to tip rolling, thanks to its stocks, which are not particularly suitable. I absolutely recommend you try the Whizzer/Kbear SS20 tips or the Tri Clarion, as they are the cheapest to try. If you want to try something more expensive, I recommend the Divinus Velvet or the DUNU S&S. For the Dunu, in particular, they may not suit you well on all IEMs.

Final sound impression:​

Equipment used for testing the above


Device:

• iMac
• Redmi Note 7 (MIUI-Based)
• Poco M4 Pro

Software:

• Amazon music UHD 24bit 96kHz
• Tidal Hifi Plus

DAC:

• Hidizs S9 Pro Plus
• Fiio Ka11
• Fiio KA17
• Fosi SK02
• Muse Hifi M4

I waited some time as usual; in the meantime, I performed a burn-in for a few days and also waited for my mind to adapt. The second-generation dynamic driver mounted has a lithium-magnesium dome and a flexible suspension. As far as I’m concerned, I won’t go into detail because I would have to disassemble a driver to verify the information but the dome seems to be made of white material and can be glimpsed by removing the nozzle. I have no doubts about the quality of the driver.


It should have the same technology as the driver mounted on the EA1000 (the dome material is different) and I believe it is also the only one in my possession with a similar composition of the dome.


Regarding the timbre, I consider it natural, even if perhaps it has a slightly colder touch than I personally like but it still has a slightly warm note. I think it might not appeal to everyone because it takes away a bit of body warmth from the mids, which could be heard as slightly cold.


In any case, it follows a V-shape curve and through the nozzles, you can have variations based on your tastes and various tolerances.


Honestly, it has a very clear and detailed tuning and the mids don’t appear to be so recessed that calling it V-shape tuning is a bit misleading.


It gets along very well with POP, EDM, house, and R&B music, in my opinion, but if you like to have a more decisive bass presence, there are certainly other IEMs that are even more suitable.

Nozzle:​

Gold Red:​

In my opinion, this is the best nozzle. Everything remains balanced and appears to be in harmony. Furthermore, it is the tuning as Simgot conceptualized it, whereas the others are variations. This nozzle was used the majority of the time while reviewing. The voices, in particular, appear to have a strong presence here.

Silver Red:​

This nozzle brings the tuning closer to the Harman target; it actually doesn’t add warmth to the sound. The highs are almost unchanged, just slightly more bright/sibilant but by relatively little. I seem to have missed some bass body and detail However, this is also the spiciest one. Already with the gold nozzle, there are somewhat borderline traces so completely removing the nozzle sponge makes some problems stand out even more. There is a minimal difference from the stock gold nozzle.

Silver Black:​

Although it looks like the gold-colored one, at first glance I might think that the sponge inside has a different density. From what I feel, it should be a lower density; in fact, the bass loses a bit of body but gains in resolution. Honestly, it’s not bad but I prefer the gold one as it’s more balanced and a little less bright.


Nozzles help a lot and are especially useful instead of switches. Because I do not like changing them frequently, I choose the most balanced option. I am not sure why the two with red gaskets look so similar, whereas the silver/black one reduces bass and increases treble. When it comes to nozzles, the possibilities for modding are obviously limitless. Without a doubt, I would have preferred more variation between some nozzles.

Bass​

In terms of bass, we are absolutely not at basshead level but the quality is extremely good. There is a clean bass and a slight emphasis on the sub-bass without deviating from the naturalness of the tuning. The bass is precise, fast, and rich in texture, just the way I like it.


I think in terms of tuning, they probably listened to the feedback on the EA500 and improved that aspect. Their basses are very composed and present but only if required by the track. Personally, everything is particularly clean and pleasant, especially due to the precise separation they have. Maybe they are too present for some and too few for others but in my opinion, they have found an excellent balance.

Mids​

The midrange part has the voices that dominate it. Female voices are silky, vivid, and rich in detail. The best nozzle to maintain the best balance is absolutely the gold-colored one. With the one without sponge, there is no difference at all. The other nozzle with the sponge instead dampens a little too much for my tastes. Personally, the part that I consider slightly cold is the mids, which, with a slightly warmer touch, would have been decidedly more enjoyable.


I think I read that someone had a metallic experience regarding the mids but I think it’s just a sensation due to the brilliance of the tuning together with a slight resonance of the material. I can assure you that the mids are represented in a fabulous way and the musical instruments are very faithful to reality.

Treble​

I think the trebles of the EW200 are much more elevated but in terms of detail and precision, I think the Simgot EA500LM returns more detail without adding peaks that could be noticeable. In my opinion, we are at the limit beyond which I personally would consider them as such, some very complex tracks are already at the limit with the gold nozzle. If the Simgot EW200 is already too much for you, these will not be suitable for you. Even if they seem more fluid, if you raise the volume beyond the safe limit, you will certainly have the opportunity to experience some sibilance or treble situations that become very lively. The presence of air is excellent.


Thanks To Gizaudio

Soundstage and Imaging:​

I would have expected the Soundstage to be wider due to that really large ventilation hole compared to what you usually see, but despite being more intimate, the ultra-detailed, bright but above all, precise image is excellent, as is the layering. This also makes them particularly suitable for gaming, which, however, does not take full advantage of them. I must say that the sound seems to me to develop in height and depth rather than in width. The effect is at times holographic, given how clearly the image is placed in front of you. I tried it in a few games on PS4 and I had no problems locating enemies through the sounds of footsteps.


Overall, it keeps everything as natural as an audiophile would like; in fact, they are the closest thing I can think of to what one of them would want.

Comparison:​

They are in a segment where both single-DD and hybrid IEMs can be found. There are so many products in this price range but there are some IEMs with a lower price that come into play.


vs Simgot EM6L


It is not a single DD so the performances are slightly different but I would also recommend this IEM for gaming. As excellent as the Simgot EA500LM is, it does not achieve the separation and soundstage of the EM6L. Honestly, the EM6Ls are full of energy and take you in and immerse you completely in the music. They have a different approach that engages you more easily. However, I must say that the shell of the EM6L is slightly less premium and resistant than the Simgot EA500LM.


vs Whizzer HE10

Whizzer He10
If you’re looking for something harmless on the treble side, this is for you. Despite having very hot tuning, it manages to restore a lot of details and a more accentuated bass region. The bass is very present but all in all, it blends together in an impeccable manner. The slightly warm mids give depth to the voices, which honestly don’t even sound too recessed. Excellent highs that are inoffensive but still rich in details with a good presence of air. I don’t think I have a review here on MBA but I’ll give you the link to the one I did. In my opinion, it is a hidden gem that has never had much success. It remains one of my favorites, together with the HE01, which is often found at super discounts.


vs Kefine Delci


The Kefine Delci are the new monsters in the sub 100 territory. Making a direct comparison with the Simgot EA500LM is difficult, as one is for Bassheads and the other is not. What I can tell you is that if you like a lot of bass, this IEM is for you. Furthermore, it has an ultra-light CNC machined shell with a very good driver capable of maintaining details and good sound despite the bass. They are a must-have set and are also extremely competitively priced. How could I prefer one over the other? Honestly, personal taste comes into play here. The Delci has a fun approach, while the EA500LM has a more serious profile oriented towards more audiophile listening. If we add the price factor, it is obvious that Delci is the winner in terms of quality/price ratio.


vs Simgot EW200


It is the Simgot that comes closest to what the EA500LM are. Obviously, they can’t compete but if you’re short on money, the Ew200 is still a great alternative. If you want something even better, the EPZ Q5 has a slightly warmer tone and a wider soundstage. Even technically, I would consider them slightly superior but they have a rather obnoxious and delicate MMCX connector.


Despite their similarities, I find them to be slightly warmer, with a bass that appears to be the same quantity but has a less heavy/beefy and slightly slower impact.


I would like to say that the EA500LM can be considered an upgrade of the already excellent EW200. Although double the price in this case does not mean double the sound quality.

Conclusion:​

Unfortunately, I was unable to test the EA500, but based on the graphs, the EA500LM is a variant developed in response to user feedback. Personally, I find them to be IEMs with a high quality/price ratio, especially under 100 dollars. They have a purely audiophile nature where quality comes first; there is a slight note of fun but they are purely serious. I cannot hide a certain similarity with the EW200, which, despite costing half the price, still manages to compete in the same race. The real monsters are IEMs like the Ew200, EPZ Q5, and now also the Kefine Delci, which, despite their price, stand up to IEMs that cost twice as much. The Simgot EA500LM is undoubtedly better since the definition and details are a step higher but not by much.


Aside from rock, I think it works well with a variety of genres, particularly those from the 2000s. I am quite young, and I admit that I mostly listen to modern and electronic music, even though I experiment with every musical genre without any real preferences. As far as I am concerned, it is a tuning that works well with a variety of genres.


What I have noticed is that it requires a good dongle to express itself properly. If you have a slightly warm one, I think this combination is ideal, but it also works well with the SIMGOT DEW4X, which is slightly neutral. Another thing to consider are the tips; clearly, this is an IEM that is heavily influenced by tip rolling.


If your budget is limited but you want Simgot’s sound signature, the EW200 could be a great alternative to the EA500LM. Obviously, you will sacrifice some macro and micro details, resulting in a lower resolution but still above average.


Considering the cost-benefit factor, I see myself having to give a slightly lower rating to the Simgot EA500LM, this is because the wow effect is superior to the EW200 which are truly fantastic in that price range.

Good morning, Readers! Today I have the honor of reviewing a product from Creative Labs! The Creative Aurvana Ace 2 is one of the first TWS to feature the brand-new xMEMS drivers.


When they first contacted me, I did not believe it was them because they are a large and well-known brand, but I had to change my mind. I have previously owned their products, including 2.1 PC audio systems and, more recently, the Creative SXFI® AMP, which is still one of my favorite dongles.


Because these TWS are decidedly complex products, the review will be a little more detailed than usual, with the goal of highlighting all of the product’s advantages and disadvantages.

Tech Specs:​

Packaging:​

The Creative Aurvana Ace 2 comes in a surprisingly small package, but with meticulous attention to detail. To open the box, we need to remove the two seals on the bottom. We can immediately see that the Creative Aurvana Ace 2 is enclosed in a plastic bag; above them is the housing for the included accessories, and at the bottom of the package is a manual with quick instructions in multiple languages.


As accessories inside, we find:

• 3 Pairs of oval tips
• Type C into USB charging cable

Personally, I would have added more eartips and perhaps a small bag to store the earphones in the package. They are two small accessories that I would have liked to find in the package.

Design/Build Quality:​

The Creative Aurvana Ace 2 features a distinct design. I will begin by stating that the materials used are of a certain quality; the charging case weight is primarily due to its thickness. The satin smoked plastic choice allows you to get a vague glimpse of the interior and components (I personally prefer this look). The shiny copper contrast enhances the overall effect.


The case has Aurvana writing on the front; underneath, there is a master reset button, a case status LED, and a Type C charging port. On the back, however, we can see the label with the certifications and some model data, as well as a glimpse of the wireless charging.

Front & back
Opening the case reveals that this design choice extends to the TWS, which houses the 10 mm driver, Bluetooth modules, and batteries. Two small status LEDs are located on both sides, beneath a small copper-colored perforated insert (which I believe houses the microphones). On the other side, we notice how on both sides there are two ventilation holes. The nozzle, as on many TWS, is unfortunately oval. This feature doesn’t drive me crazy but I don’t consider it as a problem. What perplexes me is the near-impossibility of replacing the original eartips with those already in my hands. Luckily, the original ones are fine but I would have left more space in the case so we could put the tips we like best. Using Divinus Velvet for example, the TWS are unable to go all the way and therefore recharge.

Built-in Technology:​

The Creative Aurvana Ace 2 is a concentrate of innovations. First of all, let’s talk about the Bluetooth technology used:

“Experience superior CD-quality clarity and precision, enhanced by Snapdragon Sound™ with Qualcomm® aptX™ Lossless technology, Qualcomm® Adaptive Active Noise Cancellation, and more. These premium features are beautifully complemented by an aesthetically pleasing translucent compact charging case.”
Creative Labs

Click to expand...

Creative has integrated a Qualcomm chip, which is responsible for processing the audio and managing noise cancellation via the 6 microphones. I’m sure I’ve located 2 of them, while I’m still looking for the third. A microphone is underneath where the charging pins are, one in the copper colored insert but the third could just be one of the 2 holes that I thought were ventilation.


It integrates another technology called Bluetooth LE (which stands for low Energy) but to be able to use it, you will probably need brand new smartphones or adapters capable of this new technology and the possibility of using the new LC3 codec. In my case, I was not able to thoroughly test the numerous codecs as I have a Poco M4 Pro (which can only use them in AAC) and a Redmi Note 7 (which can use them in aptx).


This is to tell you that to take advantage of the latest codecs, seventh/eighth generation Snapdragons will certainly be needed.


Are they necessary to enjoy unprecedented sound quality? In my opinion, no! From what my ears hear in AAC, we are well beyond even Hifiman Svanar Wireless in LDAC.

xMEMS:​

The real peculiarity of the Creative Aurvana Ace 2, however, is the driver with xMEMS technology. These new drivers are slowly appearing among the newest IEMs and TWSs.


I’m certainly not the best suited to understand this new technology but in any case, these are solid-state drivers with piezoelectric technology and silicone membranes.
They are rectangular in shape and in the case of Creative, we have the DD with xMEMS in front. From the photos, you can see something that could be the special driver.


I leave you with the site that talks about this new technology:

Home

Click to expand...

xMEMS Official Site
On the Creative Aurvana Ace 2, the xMEMS driver is responsible for the high frequencies and all the details, while the dynamic driver placed on the back is responsible for the low and medium frequencies. I didn’t find any details on the type of driver used but the result goes well beyond my expectations for a wireless product.

Fit & Comfort:​

The Creative Aurvana Ace 2 is undeniably comfortable; they do not move in my ears, and I can use both the medium and large tips for a deeper and more comfortable fit. Even when moving, they remain stable, but everything is dependent on the shape of the ears. The charging case is comfortable and compact; however, if you have slightly fat fingers, you may have difficulty removing the TWS.

Tips Rolling:​

As I previously stated in the design section, the eartips cannot be changed at will. You will probably need to get them in an oval shape, as the classic ones do not let the TWS touch the charging pins. So, in this case, I am unable to advise you on alternatives at the moment.


Update:


Tanchjim MINO Tips on the front (longer & bigger M size)
I have not received any new tips, but I own the Tanchjim MINO medium tips, which are also oval but fall somewhere between sizes M and L. As far as I am concerned, sealing and stability have reached their peak. There is a small improvement in the low range.

App & Features:​

The Creative Aurvana Ace 2, thanks to Snapdragon technology, has one of the best ANC and ambient modes I’ve heard so far. Compared to Hifiman Svanar Wireless, which costs much more, they perform much better in all situations. The gestures for mode, music, calls, and volume control work well, but the Creative app only allows for limited customization. In this app, we also find the possibility of checking the battery status of the TWS, changing the modes, and, above all, having access to different presets with the possibility of creating new and personalized ones. Everything is so versatile that we honestly have the possibility of making it have the sound signature we prefer.


Another very important thing is that you can update your Aurvana Ace 2 via the app. The first update is a little slow but please be patient.

Gestures for Calls & Music:​

Audio Codecs:​

I haven’t had the chance to try the best performing codecs but as far as I’m concerned, the stability in Aptx and AAC is really very high. Without barriers or obstacles, you can actually reach just over 10 meters; then, it depends on the smartphone and also any interference nearby. I hope in the future to get a new smartphone with a recent Snapdragon processor to understand if I have missed something so far or not.

Equipment used for the testing above.​

Device:

• Redmi Note 7 (Aptx)
• Poco M4 Pro (AAC)
• Hotwav Pad 8 (SBC)

Software:

• Amazon Music UHD 24bit 96kHz
• Tidal Hifi

Sound impressions:​

Track after track, I realize that we are closer to the result of some planar IEMs, with the difference that the bass comes from a dynamic driver. As for the sense of spatiality and high resolution, in addition to the drivers, there is also an excellent tuning job by Creative, which has certainly added its sonic signature. I can’t say that with the preset on FLAT, it’s a natural and neutral listen but they are certainly as fun as they are serious. I didn’t think similar quality on TWS was possible and yet I had to change my mind.


In terms of maximum volume, I would have liked a little more but it’s only because I’m used to using dongles where more reckless volumes are reached.


Another big surprise is that switching between ANC and Ambient modes does not cause any major changes in the sound. Something I had experienced on the Svanar Wireless.


In my opinion, they are excellent V-shapes on flats, even if the response would have been to start with a more neutral one.

Treble​

The high frequencies are never harsh or sibilant in any situation, but the amount of sparkle and air is truly impressive. The sensation of depth provided in contrast to the dynamic driver is the most striking aspect. You literally hear sounds beginning and ending in different places. You can position musical cymbals and violins with accurate precision.

Mids​

I don’t actually find the mids to be so recessed; on the contrary, they are very natural, rich in details, and silky. Both male and female voices are full and vivid, as are musical instruments, especially stringed instruments such as guitars. You can really focus on the vibrating strings.

Bass​

The bass has a decidedly important presence, making the Aurvana Ace 2 very fun but at the same time serious due to the quality of its bass. Even with regards to the sub-bass, there is emphasis, which at the same time helps to give a sense of spatiality. The basses are decidedly full-bodied and rich in texture, as I like them but what enriches them is that sensation of air movement that makes them atmospheric. It vaguely reminds me of the effect on the Hidizs MP145 but more pronounced.

Soundstage & Imaging:​

At the moment, it’s the TWS that has surprised me the most in terms of soundstage, perhaps it’s also a little too extreme in terms of effect but I like it. It embraces you and immerses you completely in your favorite tracks and in ambient mode, it almost seems like an openback. The image here too is very clear and detailed; all the sounds are composed and well separated. In terms of overall quality, we are close to some IEM worth 80 to 120 USD, in my opinion.

Practical Consideration:​

In everyday use, they are the ones that absolutely stood out from the other TWS in my possession. Taking Svanar Wireless as an example, these are certainly superior in several aspects. The most important side is the audio, on which Creative Aurvana Ace 2 is no joke at all. Then we have Creative support and the companion app with firmware updates. The ANC and ambient modes work very well and do not cause any sound changes. The ambient mode is very sensitive, it allows you to hear various noises, even faint ones such as birds in the distance.


However, it brings a white background noise that I have already experienced on other TWS, Audible if the music is at low volume or paused. In any case, the mode works well and the microphones capture a lot of details from the outside. The ANC also has excellent external noise suppression, which is good even without activating it. In everyday use, I had some difficulty with gestures, and sometimes they did not recognize them correctly. You have to aim for the highest part of the TWS and sometimes I obviously touch with little decision and lower than necessary.




With some regret, I saw that to raise and lower the volume, you can unfortunately only choose the long press. The only change made was to remove the voice assistant and add the possibility of returning to the previous track. I hope they add total freedom of customization and also the single tap, which is currently not available.

What could be improved?​

Although there was the possibility of bringing out the details with the new driver, they opted for a sound with a lot of bass. Fortunately, through EQ, you can still achieve the tuning you prefer most.


As for the ANC functionality, I admit that it adds a bit of ground noise, which is especially noticeable between pauses during a phone call or when switching from one song to another. Same thing in ambient mode, where the ground noise becomes more accentuated but the same happens on other TWS too.


But honestly, compared to the Hifiman Svanar Wireless, they fare much better.


The review was done with the latest firmware available but a new one could easily add options and fix some things.The app currently has some bugs with the equalizer that I have to adjust on a second device connected to the TWS.

Update:​

I managed to get around the EQ problem by starting to play music saved on my phone and then starting a streaming service (Amazon Music). In this way, I managed to get the equalizer back.

Fast Comparison:​

vs Hifiman Svanar Wireless

Svanar Wireless sunset
The Svanar Wireless has a decidedly high price but despite this, they disfigure compared to the Creative. The sound is much more neutral and flat, certainly not as fun as the Creative one. The features are unfortunately poorly implemented in comparison. We don’t have an app; there are no updates; finding compatible tips is almost impossible; and even wearing them is quite difficult. When they first came out, they cost 500 USD, and you would expect the best of the best. Let’s be clear, their Topology driver sounds really good in high fidelity mode, much more natural.

Conclusion:​

Creative is a fantastic brand, and I am confident that after conducting some xMEMS TWS, they will have discovered the recipe for the ultimate TWS. The Creative Aurvana Ace 2 will be my new daily TWS from today. Their sound is especially pleasing to my ears, and the level of detail in general does not make me miss the wired stuff I enjoy so much. I am hoping that with an update, the current flat preset will become a “Creative Sound House” and a true flat will be introduced to showcase that fantastic xMEMS driver.


As for the ANC & Ambient modes, I am convinced that Sony and Bose still hold the crown but we often talk about much more expensive products. Creative has improved these modes with the updates and honestly, when using it on the road, I haven’t noticed any major problems. In Ambient mode with a volume not too high, I can continue to speak with friends and hear the noises around me, while with ANC active, the suppression, although not total, completely removes the noises to the point of making them barely perceptible.


P.S. I will update the review in case of future firmware upgrades.

Disclaimer:​

Good morning, readers! Today I can finally review the Shanling Sono, which were kindly sent to me by them. I hope to have the opportunity to try some of their dongles in the future.


Reading online reviews I noticed how many did not take into account some particularities of the SONO. I will try to carry out a complete analysis.


I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music.


So I’m not going to use super-technical words to review it, but I will do my best to describe it.

Tech Specs:​

Packaging:​

The packaging is refined and simple in design, reminiscent of the packaging of the Muse Hifi East 6 and some Simgot. Inside, we find the Shanling SONO. They are surrounded by accessories. I found the equipment to be correct for the asking price.


Inside, we find:

• Tips of two types but only one pair of double flange
• Decent-quality cable
• Case (anonymous but good)
• 2 pairs of nozzles
• Manual

Maybe I would have liked to see at least the double flange tips in a complete set but I find the rest adequate. Then there is a question about the particularity of the nozzles, which I deal with in the following paragraph.

Design/Build quality:​

I like the chrome-plated metal IEMs a lot, but I think many other resin IEMs are sometimes unable to compete at all. It’s very personal as a preference; some resin IEMs are works of art. The Shanling SONO design is minimal but this time the shape is correct for absolute comfort: compact and with soft corners.


They fit into the ear without causing discomfort. The Shanling logo appears on the faceplates, and you can see yourself in the mirror. There is only one ventilation hole on the internal side because they chose to place the second one on the nozzles. This choice perplexes me because the nozzles are relatively short, and the hole could be covered by the installed tips. The original tips have a slight step in the “mouth,” but most of the ones you buy don’t. Naturally, covering a vent causes changes, especially in terms of bass response and pressure. I am not sure why we did not make the ventilation hole right before the nozzle. When we remove the nozzle, we can see that the double DD is in the center of the IEM and that the BA is placed sideways, rather than straight and shooting into the ear. I was surprised that none of the reviews I read mentioned this peculiarity. The sound changes, and so does the rating.

Initial sound impression:​

At first listen, I wasn’t particularly impressed by the black nozzle. As a source, I used the FiiO KA17, which is my new point of reference. I noticed its strong V-shaped tendency. The bass response is particularly aggressive; we are almost in Bassheads territory, with sparkling highs but the voices are a little covered. Coming from Kefine Delci, I wasn’t surprised.

Nozzle Filters:​

At first glance, the filters look very similar; both have a tuning sponge in the nozzle, which appears to have a very similar density. They both have a vent hole that you need to be careful not to cover (Shanling confirmed that it needs to breathe). Let me start by saying that the differences are minimal. The nozzle with a black o-ring is for a balanced sound and actually the bass is less accentuated, while for the red one, it seems to bring out the V-shaped signature more. Despite this, I prefer the fun approach. In my opinion, it also sounds better in terms of definition or the perception improves by reducing the highs a little. At high volume with a balanced nozzle, the highs become a little biting.

Comfort & Fit:​

As anticipated, the shape of the shell is spot on; if the Muse Hifi East 6 had had a similar shape, it would have been a good buy. These are absolutely comfortable. The double coaxial DD, one above the other, allows it to remain compact with the shell. You just need to pay attention to how the tips are mounted. Lightweight, hassle-free cable.

Final sound impression:​

Equipment used for testing the above


Device:

• iMac
• Redmi Note 7 (MIUI-Based)
• Poco M4 Pro

Software:

• Amazon music UHD 24bit 96kHz
• Tidal Hifi Plus

DAC:

• FiiO KA17 (strong bass response)
• Moondrop Dawn Pro (bass increases)
• Simgot DEW4X (mids and treble improvements)
• EPZ TP50 (good balance)
• iBasso DC04 Pro
• Muse Hifi M4
• Hidizs S9 Pro Plus (better mids)
• Fiio Ka11
• Fosi SK02 (less bass, more brightness)

I gave them about 10 hours of burn-in but as usual, I think it’s more my brain getting used to it. The red nozzle certainly gives some satisfaction in terms of bass. Even in terms of definition, technicalities, and soundstage, there are now DD singles that have raised the competition tremendously. On a similar hybrid, one expects a precise division of frequencies, which is there but is especially present for the basses, for which one feels that 1 DD is responsible for these frequencies and in fact, they are produced in a more than excellent way. The trebles, instead left to BA, are slightly affected by the somewhat cold timbre of BA. The DD responsible for the mids and, therefore for the vocal part is a little sleepy. The voices are recessed and dull, not at the same level as some single drivers.


After several hours of testing, however, I realized that the red filter overshadows the mids and therefore the voices even more. I went back to the balanced nozle and continued the evaluation using that.


I used the FiiO KA17 most of the time and then switched to the Fosi SK02, which has a brighter sound. The Shanling SONO is particularly suitable for bright sources rather than warm sources. However, although the bass has softened on the mids and highs, the timbre is a little unrefined.

Tips Rolling?​

The rolling tips are quite complex due to the fact that they decided to put a nozzle, which requires tips mounted at the tip. The stocks have a step that keeps them stable even if inserted very briefly into the nozzle. The only ones that could be similarly stable are Divinus Velvets.

Bass​

The bass is good, almost at basshead level but not enough to enter that category. With the black nozzle, it doesn’t stand out, while with the red nozzle, it becomes more impactful and enveloping. To tell the truth, with the red nozzle, the bass becomes more enveloping. Good depth, strong impact, quite fast.

Mids​

The DD, who should take care of the mids, is a little overwhelmed by the rest. The tuning is absolutely V-shaped, but the mids are particularly not very vivid and energetic. The result is that the voices do not have the silkiness and refinement that we expect. They appear a little dark and in the background, failing to fully inspire. Let’s be clear: they are not that bad but there are better representations of mids on the market. If you want to improve the presence of the mids, the balanced nozzle is more suitable.

Treble​

The highs are quite good, there is the right presence of air, the brightness is there without being excessive, and they seem quite smooth to me. The best representation is with the balanced nozzle, which returns some energy to the mids and continues up to the highs. At high volumes and particularly complex songs, the treble becomes slightly spicy due to BA timbre.

Soundstage and Imaging:​

The soundstage is quite good but certainly below average, and the image is precise thanks to the presence of drivers with divided frequencies. Since IEMs are already more than a few months old, several options have been released with even superior performance. All the sounds do not go far outside the ear, and although they are all distinguishable, the sensation is of intimate listening. Personally, I like it but maybe some might expect more.

Fast Comparison:​

vs Simgot EM6L


The Simgot EM6L is special. Full of energy, musicality unmatched anywhere in my collection, and brilliant, vivid, and present voices. There is air in the treble area and a very pleasant soundstage and imaging. As hybrids, they are, in my opinion, one of the best representations in this price range. The low range is excellent and is less pronounced than the SONO but still pleasant.


vs Kinera Celest Phoenixcall

Phoenix Faceplate
Kinera produces hybrids with exotic configurations and a particular sound. The Phoenixcalls are slightly over budget but worth mentioning. Very pleasant and above all, the voices are much more present and at the center of listening. They impress you more at first listen than the SONO. Less natural timbre, less present bass.


vs Kinera Celest Plutus Beast


They sound brighter than the PhoenixCall, with a more tactile bass perception thanks to the BC driver. The sound is immersive and envelops you. Even if you don’t particularly follow fashion, Kinera manages to produce products that stand out from the crowd. In my opinion, these that are positioned at the same price have a more pleasant sound and balance, at least for my personal tastes.

Conclusion:​

Being a model that is now a few months old—to be honest, 8 months—I imagined that it might have been slightly inferior to the newer models. It is still technology that evolves every day. A few months for an IEM is a huge period. The Shanling Solo is, however, a high quality product. Some accessories look very similar to those seen on the Muse HiFI EAST 6, such as the case, which is identical. The construction is similar and of high quality, and the sound is very good but there are now IEMs in this price range and even at a lower price that have literally dominated the market. I am sure that Shanling has much better performing models than SONO and, above all, excellent-quality dongles and DACs. By lowering the price of this model, it could easily return to selling on the market.

Disclaimer:​

Good morning, readers! Today, we are going to test the new Fosi DS2. The dongle has undergone a hardware review and now has a certain interest, especially in the entry-level range. As usual, I thank Hifigo for the review unit.


The Fosi DS2 features two CS43131 chips. The market is now full of dongles that use this chip and the choice is increasingly complex. However, the new DS2 has price and power as its strong points.


The review, as always, will be completely unbiased and uninfluenced.


I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.


My opinions are obviously subjective.

Tech Specs:​

• Dual CS43131
• Sampling Rate: 32-bit, 384khz / DSD256
• THD+N: 0.0001%,
• Noise: <1.6UV.
• Frequency response: 20Hz-20kHz (±0.5dB)
• S/N: ≥130 dB
• Power : SE: 130mw /32Ω, BAL: 510mw /32Ω
• Hi-Res certification
• Independent volume

Packaging:​

The packaging is very simple, I would even say a little oversized, half the box was enough.


Fortunately, inside, we find the following accessories:

• Type C to Type C cable
• USB A adapter (always much appreciated)
• Manual

In terms of first equipment, I think it’s more than fair. The Type C cable reminds me of some cables I’ve already seen, very flexible.

Build quality/First impressions:​

I’ll start by saying that I didn’t own the old DS2 but judging from what I’ve seen, the shell is identical. They have kept the same design with an aluminum shell, which is very light but resistant. Personally, I really like the gunmetal-like color; aesthetically, it is very minimal. On the front, we find the LED and the “Fosi Audio DS2” labeling, and on the back, we simply find the Hi-Res sticker.


On one side, we have the volume buttons and nothing else. Personally, I would have liked to find something written on the shell so as to immediately identify that it was the new model. The gain switch is missing; honestly, I would have put it there. It’s not essential but let’s say that if you have particularly sensitive IEMs, in some cases you might need it. But fortunately, it still has independent volume and allows precise volume adjustment.

Power:​

The Fosi DS2 has decidedly generous outputs; the declared values are both at 32 ohms, so for headphones with lower ohms, you will have considerable power available.


To give you an idea of the DS2 power, with the 28-ohm Kefine Delci and the volume set to maximum, my iMac only requires three volume bars out of sixteen. Getting to half the volume is extremely difficult. You won’t have any kind of problem with any IEM that comes out with SE cable.

Macro Outputs
While the 4.4mm side provides even more power, switching to the Hidizs MP145 requires only 5 volume bars out of 16.


The thing that surprises me is that despite the decidedly low price, it is one of the most powerful CS43131 dongles currently on the market. By now, the entry-level products have reached decidedly very high quality. With a product like this, you can easily use planar headphones without problems.

The lack of a gain switch is made up for by an independent volume that combines with the volume of the device to which it is connected, giving you many more adjustment possibilities.


During the test with my iMac, I discovered a strange peculiarity: when I stop and restart a song, the volume gradually increases (which I think is a fantastic feature); however, I have noticed that the volume sometimes comes from one channel rather than the other. The operation is bizarre, and I am not sure if it is a firmware bug or not, but it seemed appropriate to inform you. There were no issues while changing tracks.

Sound Signature:​

The Fosi DS2 is slightly atypical for a Cirrus Logic dongle. In terms of sound signature, it is more similar to the new CS43198, although in terms of definition and refinement of the sound, we are more on par with the newest CS43131 on the market. The bass is slightly smoother; it follows the bright line, giving it the right balance with some aspects of the Fosi SK02. It has a decidedly brighter sound than other Cirrus Logics, with a good soundstage and amount of detail. It has some resemblance to the iBasso DC04Pro; both are practically colorless and very flat, although in my opinion the DC04Pro has a very slight difference (in its favour) more in terms of soundstage and refinement of details.


The New Fosi DS2 costs practically 60 USD and has a very high output power that you can’t complain about and the differences in terms of details can only be noticed by those who have many other products to compare. An entry-level user who picks up such a dongle can only smile from the first listen to the last. Basically, it is a very natural-sounding dongle, and I feel it has a very flat sound compared to many others. You might like it for this feature. There aren’t many DACs without coloration.

Fast Comparison:​

If you want other comparisons just ask and I will answer you.


vs EPZ TP20 Pro


The EPZ TP20 Pro is an excellent dongle; it sounds extremely good, they have improved the shell, it has the gain switch but otherwise it has no other features. We can say that it is very similar to many others in terms of configuration. It sounds great but it comes at a higher price than the others.

vs Hidizs S9 PRO Plus​

With Hidizs S9 Pro Plus, if you like warmer and slightly more present instruments and voices, the Hidizs sound signature doesn’t miss a beat. It has currently dropped in price so its purchase is very close to the price of the Cirrus Logic dongles, which, as we know, are the cheapest. Personally, I like it a lot but if you have some planar to experiment with it, the Fosi DS2 has more power in reserve.


vs Moondrop Dawn Pro


The Dawn Pro was the CS dongle that dominated the others. Very low price, working app with some settings, compact shell but with some defects. But for 50 USD, it’s honestly one of the best entry-level ones yet. They are slightly different; the Moondrop has a slightly warmer sound coloration and a slightly nicer design (personal) but sometimes the QC strikes. Honestly, I would currently opt for the Fosi DS2, which is slightly more powerful and therefore should be enough for several IEMs and headphones. The app isn’t that essential.


vs FiiO KA11

FiiO Ka11
It may seem crazy to you, but with a small dongle like this, many of us will be completely satisfied. With its unique outputs, it has few competitors in terms of SE output. Most of us use headphones with the classic 3.5mm jack, so the FiiO KA11 is all you need. The app works reasonably well, and there are firmware updates available. With its features and, above all, thanks to its slightly warmer sound, it has become one of my favorite dongles for everyday use. Especially when I’m traveling, it’s the most compact solution possible.

Who do I recommend this DAC to?​

The Fosi DS2 competes with the other dongles mentioned above. I think for the price, this one slightly beats the Moondrop Dawn Pro in terms of build quality and versatility. Moondrop has an app and you have the ability to manage some dongle stuff but at the same time, the quality of the dongle is slightly lower than the Fosi DS2.


In direct comparison, the choice depends on your preferences; they both sound very good for entry level and personally, I would choose the new Fosi DS2 as the versatility is greater. As regards possible distortions, in my opinion, they wanted to keep a very high gain to have a greater volume, even on devices with software and hardware limitations. This means that the volume setting on the dongle should be kept lower. I doubt that any of you will reach such high volume levels.


Regarding the soundstage, I was influenced by the last month, in which I only used the FiiO KA17. Initially, I wasn’t particularly surprised, as I was on higher-performing models but after carrying out a comparison with the others, I noticed that it was almost on the same level. The Fosi DS2 performs very well, especially for its price. Consider that the similarity with the DC04Pro is truly remarkable, unlike the fact that iBasso has the app to manage some features of its dongle.

Fosi Audio DS2 Dual CS43131 Portable Dongle DAC Headphone AMP

Disclaimer:​

Good morning, readers! Today FiiO sent me the FiiO KA17, a portable dongle with an almost desktop configuration. I currently believe it to be one of the most powerful and complex dongles in my possession.


The review will be more complex than usual and possibly longer. To make comparisons, I don’t have any recent desktop Dac/Amp so I deduce that any comparison would be superfluous but I will try to do my best.


The review, as always, will be completely unbiased and uninfluenced.


I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.


My opinions are obviously subjective.

Tech Specs:​

More information:

• https://fiio.com/KA17_parameters
• https://fiio.com/KA17
• https://www.esstech.com/essnews/ess...nnel-audiophile-digital-to-analog-converters/

Packaging:​

The packaging of the FiiO KA17 is simple but refined. Just opened, we have the KA17 and its imitation leather case, a very welcome accessory, in my opinion, given the price of the dongle.


Under the first layer, we then find the type C cable and the USB A adapter (thank goodness).


The set of accessories is, in my opinion, correct for the price; if we want to be picky, I would have liked a slightly more robust type C cable. The cable for the additional power supply is missing but personally, I have so many cables at home that it is the least of my problems.

Build quality/First impressions:​

The FiiO KA17, being a flagship dongle, also boasts excellent build quality. The product is solid, not too heavy, and not too large considering the double PCB it contains; in fact, FiiO has kept the analogue part separate from the digital one to avoid background noise and possible disturbances. The Oled display is excellent, I think it is the same model that I have already seen on the EPZ TP50.


Honestly, I hope to see more and more displays on dongles, as they allow you to manage various settings without having to use apps. In my opinion, the screen is much faster than using the app. Returning to the build quality, it seems excellent in every respect, metal shell (the dissipation seems good even with the case), volume buttons, desktop mode, and a button to access the menu. On one side, we have the red type C input for additional power. Another very small constructive criticism is that I would have used two metal audio outputs like those seen on the Fosi SK02.

App & Firmware:​

I waited a while to test the FiiO KA17 and after a quick check with the factory firmware, I immediately updated following the instructions that we can find on the official FiiO website. Currently, the most recent firmware is 0.99 but I believe some other updates will arrive in the short term. In any case, the main improvement is the possibility of using the PEQ app, one of the most complete I’ve seen so far. However, when the FiiO KA17 switches from EQ ON to EQ OFF and vice versa, playback is interrupted. This happens because the interfaces are somewhat separate. When the equalizer is active, the dongle is limited to 24 bits at 192 kHz, and when you enter and exit these modes, the device it is connected to recognizes it as a new connection.


For example, Tidal will request access in exclusive mode again. The FiiO application can also record both interfaces but you will only need the interface that you can record with the EQ ON. I can’t tell you if in the future they will be able to make this functionality more fluid, currently, it is absolutely usable, just leave the EQ on and if by chance you don’t want it, there is the EQ bypass, which allows you not to turn off the PEQ but still hear the sound without any change. Having said that, once you have created your presets or modifications, the app is not strictly necessary as you can easily access everything via the display.

For the functions of the menu, I leave you a small reel, which is certainly more practical and useful.​

1. Gain Selection: High or low gain selection
2. Filter selection: 8 digital filters
3. Volume steps: you can choose between 60 and 120 volume steps
4. S/PDIF: you can enable this function
5. ADV-L/R: To adjust channel balance
6. Dimmer: Display brightness
7. EQ: 7 preset EQ + 3 Custom profiles
8. Max Volume: You can limit the volume
9. Rotate Display: Display orientation can be adjusted
10. OFF Display: display auto off after inactivity
11. U-audio: USB mode selection
12. Language selection
13. Version: Firmware check
14. Recovery: Factory Reset

Firmware Download: FiiO Forum


MQA disappeared from the menu in the latest update and is now automatically activated when playing an MQA file, as long as EQ is deactivated. On my POCO M4 PRO, I noticed some micro-interruptions in playback when I switched from one interface to another (the problem could easily be attributable to the smartphone), however, once I entered MQA mode, if by chance you have a mixed playlist, I noticed that it was not able to exit that mode, playing no sound in the case of FLAC.

Power:​

The FiiO KA17 has certainly raised the bar on the market; even if it doesn’t have to be a race to see who has the most powerful output, this dongle makes me smile so much. Unfortunately, I don’t have a lot of space for desktop dac/amps and seeing such a small dongle be able to deliver such power is truly fantastic. FiiO did an excellent job with two ES9069Q chips and two OPA1662 Op amps, accompanied by a balanced THX AAA 78+. A real madness that could be seen on a desktop DAC/AMP but hardly on a dongle. To make the 3.5mm output a little difficult, I asked for the help of the 75 Ohm impedance adapter but I can tell you that even when approaching 100 Ohms in total, the FiiO KA17 does not seem to be affected.


Honestly, I had no doubts since even the slightly less powerful Fosi SK02 had no problems.


Below are some of the tests I carried out.


The tests were carried out in high gain and desktop mode, using supplementary and non-supplementary power.

Test of the SE 3.5mm with 270+270 mW at 32 ohm:​

• Kefine Delci: Another pairing that particularly stands out. The Delci are truly great IEMs and together with the FiiO KA17, they are truly a spectacle.
• HIFIMAN Sundara:You need to squeeze the volume a little more until you reach 40/60. Openback planars really need a lot of power. It doesn’t make much sense to stick with an SE cable if you can use it balanced.
• EPZ Q1 Pro: Obviously, no problem. I feel like she added a bit of bass.

Testing the BAL 4.4mm with 650+650 mW at 32 ohm:​

• Hidizs MP145: The sound signature goes with any IEM. The MP145 has enough power. The bass is full and powerful, and the details and soundstage seem better than usual. Really good synergy. 25/60 of the volume needed.
• Letshuoer S15: is pretty similar to the MP145 in terms of needed power. 20/60 of volume due to his brightness
• Kefine Klanar: Similar result and same volume of MP145 needed. No efforts at all.
• EPZ x Tipsy Star One: 64 ohm Star One on balanced only needs the volume at 20/60. At 30/60, we are already well above the volumes considered safe for long listening sessions.
• EPZ Q5: Obviously, no problem; it would work fine even on a 3.5mm output so on a balanced 4.4mm, it needs very little volume on the FiiO to play correctly. The synergy of this pairing stands out particularly.
• HIFIMAN Sundara: On a balanced cable brings literally life; the power of the FiiO Ka17 unleashed the dynamics. With the volume at 30 out of 60, we already have excellent sound pressure and good volume. Hifiman headphones and especially planar openback ones, also need a lot of current due to the very high dispersion they have outside.
• HIFIMAN Sundara Closeback: Also, having the closeback model allows me to make an objective assessment and say that openbacks really have a lot of dispersion. Compared to the same volume, we have a much higher volume.

Power management:​

After a month of using it, I realized that the second power supply is not extremely necessary to activate desktop mode. If the device you connect it to has the capacity to supply at least 5V and 1A, there will be no need for the other power supply. Nowadays, I believe that both the latest Mediatek and Snapdragon can easily handle it. If you don’t want any drain on your phone’s battery, then you’ll have to use external power. On my Poco M4 Pro, I don’t seem to notice any lack of power, but it is also true that the KA17’s power supply is very efficient; there is no interruption or background noise when connecting the external power supply. FiiO did a great job of isolating interference.


On my smartphone, despite the dual power supply on the FiiO KA17, the volume is lower than on the PC. I deduce the limitation is not due to the lower current but mostly due to the phone’s software. I am in Europe and unfortunately, we have limitations to prevent hearing damage.


The only background noise is heard when you leave it connected to external power but the data cable is disconnected.


In the meantime, I bought two type C testers. In the future, I will update the review to tell you how much current it requires.

Sound Signature:​

The sound signature of the FiiO KA17 somewhat follows what I heard on the FiiO KA11. It certainly follows the FiiO sound style, very technical, excellent neutral tendency, only slightly warm. I think it is the dongle that is closest to the iBasso DC04PRO, or at least I think they are very close. Since PEQ is available, you can still adjust the sound to your liking, making the versatility of the FiiO KA17 absolute. You can make it as cold or extremely hot as you like. I love the sound of it as FiiO produced it. Being neutral, it pairs well with any IEM without significantly changing its sound.


The combination of DAC, OP AMP, and THX amplification is truly remarkable, and I must say that this dongle is truly absurd. I would have liked to bring you some comparisons with some Cayin, but unfortunately, I don’t own any.

Fast Comparison:​

vs Fosi SK02


The Fosi SK02 is probably the dongle/dac/amp that comes closest to the power of the Fiio KA17. Their similarity ends there. They are two completely different products. The Fosi is very bulky; it is more suitable for desktop use, its sound signature is brighter than many dongles on the market; but it also has its own type of IEM, which it pairs excellently with. There are two totally different prices that are difficult to compare but if you are looking for power and not mobility, this is a monster.


vs iBasso DC04 Pro


Even though it is an outdated model, it is still one of my favorites. Its extremely refined sound has made it one of the best CS43131s. Obviously, it doesn’t keep up in terms of power but to this day, it remains one of my favorite dongles. The FiiO KA17, in my opinion, with all its features, takes it off the throne.


vs EPZ TP50


The EPZ TP50 seems to share the same display as the KA17; graphically, I don’t notice any substantial difference, but some heavy graphic animations on the KA17 have changed. The TP50 is a very technical and analytical dongle, from what my ears hear. It doesn’t look out of place next to this monster. Even the TP50, despite the specifications being more modest, seems to me to have a lot of power; in fact, I never know whether to trust the declared specifications. Unfortunately, the PEQ is missing, I don’t know if EPZ intends to add some presets in the future but the customizable part would probably be missing. To be honest, the price difference is very little and the FiiO has much more present support.

Who do I recommend this DAC to?​

The choice of a similar product can happen for various reasons. FiiO decided to make a similar product to see the market reaction. If sales go well (and I think they will), we will probably see a sequel. Many who enter this hobby at the beginning may buy a DAC for around 60 USD with a double Cirrus Logic chip; today, their level has improved considerably and the choice makes sense. But if by chance the hobby takes you, know that after the first dongle, the second or perhaps third will probably also arrive. The search for something better and better is constant; too many products come out and as it is always technology, it evolves every week. The FiiO KA17 is a dongle that will take away the desire for future upgrades for a while. A similar product has raised the bar so much that for a while I feel fully satisfied. On Amazon.it, it currently costs less than 160 USD, which is an absolutely interesting price. It costs more on AliExpress or in stores. It costs less than two good dongles so as far as I’m concerned, it’s worth it!

The final rating takes into account the cost, accessories, and particularities of the product.

Good morning, readers! Today we are here with a new portable speaker, the Tronsmart Bang SE. This is my second review regarding portable speakers. At home, I have several portable speakers with variable sizes and different performances. I own the whole series of the GGMM E2, E5, M4, and many others.

First of all, I wanted to thank Nora from Tronsmart for sending me the Tronsmart Bang SE.

I’m going to be as objective as possible, and being a common audio enthusiast, I will use simple words in this review.

I will highlight what I liked and what I didn’t, without any fear.

I would like to warn you that, compared to other portable speakers, this one already has significant dimensions and a weight that must be considered.

Tech Specs:​

• Color: Black
• Audio Codecs : SBC
• BT Version: 5.3
• BT Range Up to 15m/49ft (Open Area)
• Input Power: 5V/2A, via Type-C port
• Power Bank function
• Output 40W
• Microphone Built-in
• IP Rating: IPX6
• Play Time (Varied by Volume Level & Audio Content) Up to 24 Hours (Varied by Light Display)
• Charging Time: 4.5 Hours
• Frequency Range: 60Hz – 20kHz
• Playing Modes: Wireless/TF Card, USB, AUX
• Voice Assistant Supports Siri, Google Assistant, and Cortana
• SPL: 104db
• 3 LEDs mode
• Product Weight: 2.08 kg/4.59 lbs

Packaging:​

Tronsmart’s packages are always very carefully crafted. I really appreciate this brand because they produce products of very high quality. The Tronsmart Bang SE is yet another excellent speaker. Opening the package, we immediately find the speaker and its accessories:

• Type-C Charging Cable
• Aux cable
• Warranty Card
• User Manual
• SoundPulse® Card
• Strap

On the accessories side, I wouldn’t have expected anything else; the equipment is correct and the cables are good. The strap to carry it over the shoulder is simple but functional.

Design/Build Quality:​

The Tronsmart Bang SE has a considerable size. Here we are already in the territory of party speakers, who usually have more demanding dimensions. Its shape vaguely resembles something already seen; perhaps you could have opted for something more unique but I must say that the design is excellent. The handle is sturdy, it seems to be made of solid plastic, and the body is very resistant and made of good material.


The front grille this time is made of metal, and the brand is printed but not in relief, as we saw on the T7 Lite and Mini. On the top, we find all the buttons for managing the speaker and its functions.


The back part is simple; we find a silicone cap that hides all the inputs (I remind you that for waterproofing, it must be kept closed). On the sides, we find two generously sized passive radiators, driven by two white cone drivers. Together with the large battery, they contribute to the weight of the speaker. Its weight is synonymous with quality.

Built-in Technology​

The speaker is equipped with LEDs that dance to the rhythm of the music. These LEDs, which I thought were hidden behind the woofer cones, are actually behind the Tronsmart logo, in the middle, and facing the cones. They have a very high brightness and the effect is very beautiful. I must say that the LEDs follow the rhythm of the music a little lazily; they are a little less in rhythm than those seen on the T7 Lite. It’s not a problem but it seems right to point it out to you.


The Tronsmart Bang SE also has a DSP called SoundPulse, unlike the T7 Lite; however, we do not have an app to manage more settings. It is possible to connect multiple speakers of the same model to each other.


In the back, we have a variety of inputs, including Aux (which I doubt I will ever use), USB stick, and micro SD. However, if you keep the rear compartment open for an AUX cable or a USB stick, you should be aware that the waterproofing is no longer present.

SoundPulse:​

This feature slightly helps the sound appear wider and the bass has a little more body. Size limitations remain present and in terms of sound, it’s all about volumes. This being larger and having two 20W drivers, each with a lot of excursion, is able to reproduce all frequencies much better. At times, it seems like a sort of loudness function with a slight improvement in the soundstage and better clarity.


In any case, at a distance of 50 cm, peaks of 103.8 dB are reached, which is very high and suitable for indoor and outdoor parties.

First configuration and Test:​

The connection is always very fast. The Tronsmart Bang SE comes with the standard Bluetooth 5.3 module and only uses SBC as a codec. I am not sure if AAC makes a difference, but the audio quality is excellent! The 40W GGMM M4 I own focuses on quality, whereas the Bang SE combines both quality and power.


Starting from the top, we find:

• On and off button with BT and charge indicator
• SoundPulse Button
• Volume down button / if held down – previous song
• Play/pause
• Volume up button / if held down – next song
• TWS Pairing (with other Bang SE)
• Light effects

Equipment used for testing above:

Device:​

• Redmi Note 7
• Poco M4 Pro
• Hotwav Pad 8

Software:​

• Amazon music UHD
• Tidal Hifi Plus

Sound impressions:​

We cannot speak of absolute quality but the step forward is certainly notable. If the T7 Lite sounded very good for its size, the Tronsmart Bang SE at 70 USD (or less) represents a leap forward. If you don’t care about size and want to party anywhere without bringing a full-size speaker, then you are looking at the right product.


The sound has much more depth and the bass is already starting to be more perceptible in the air and therefore tangible on the skin. The passive radiators and drivers have a considerable excursion for their size and despite this, they manage to keep the mids clean and the highs quite crystal clear. Two tweeters would certainly have helped a lot, but the higher model already has them. The volume behaves differently depending on the connected device; on my Poco M4 Pro, it works independently, but on the tablet, it is dependent.

Video Test:​

Sound Test
It has a very high volume, even if beyond 80% the bass no longer increases; after that, the volume simply increases in decibels, which is ideal for open spaces. I think the fact that the bass no longer increases beyond a certain level is a solution to limit distortion; in fact, there is very little of it. Many speakers are pushed beyond their limits by distorting, while those from Tronsmart fare much better. As for the bass, I must say that this party speaker makes you have fun. It is always about bass coming mostly from passive radiators, which have a very different depth and texture than a subwoofer or woofer with a designed bass reflex.


The best example is the GGMM M4, which adopts a large woofer with bass reflex and in terms of the quality of the low range, we are on a completely different level. However, it is also much bulkier than the Tronsmart Bang SE, which is also waterproof and built in a significantly more robust way. A portable speaker is designed for use on the go and therefore must be built exactly like this one.

Fast comparison:​

vs GGMM M4​

I have always loved the GGMM M4 but carrying it with me has always been very inconvenient. The dimensions are very generous, and the weight is the same. Ruining it is just as easy as covering it in leather. Leaving aside the higher price range (now I think it’s out of production), the Tronsmart Bang SE beats it in terms of ease of use and above all, you’re not afraid of ruining it.

vs GGMM E5​

Here we enter a different territory. The GGMM E5 is a portable smartspeaker with WiFi connectivity, a physical equalizer, a dedicated amplifier, four drivers, and two larger passive radiators. What is surprising is that this speaker still has a stunning design and sound. Here we are talking about real 20W and I assure you that you can all hear it. It costs around $120 if you can still find it. In terms of design and portability, we are on a completely different level. It is not waterproof but it is a truly successful product.

Conclusion:​

Tronsmart Bang SE
As I previously stated, this type of product is becoming increasingly competitive. In this category of products, there are portable speakers that prioritize quality (obviously at a higher price) and others, such as the Tronsmart Bang SE, which costs just under $70 and provides excellent performance. For example, the GGMM M4 is also a 40W, with wood and leather materials, Texas instruments, and Wolfson chips in the components and amplification, but it cost around $200 USD. Those who want to listen to music on the go are unlikely to look for similar products, but they may want to consider more well-known brands such as JBL or Sony. Obviously, a similar speaker from these brands costs more than $200, which is not a low price like the Tronsmart Bang SE.


For the same money, you could get a JBL Flip Essential 2, which is much smaller and as good as JBL at producing bass. I do not believe it is completely capable of competing with the Tronsmart Bang SE, which has two excellent drivers. Obviously, if you want to stick to something with more compact dimensions, I absolutely recommend you read the review of the Tronsmart T7 Lite and, if necessary, evaluate the T7, which is a good middle ground.


If, however, you are looking for something even more compact, the Tronsmart T7 Mini could be an excellent choice, even if the total size varies little compared to the T7 Lite.


Now I am very excited to test the more powerful models, such as the 60W Bang and the 130W Bang MAX, especially since the latter has a full driver configuration that will undoubtedly delight. However, I remind you that if you want to experience real bass the speakers should probably be made of wood, calculated in volumes and have a bass reflex, the GGMM has all this and in fact the bass is decidedly more real even if we are still talking about a portable speaker powered by battery.

Disclaimer:​

Good morning, readers! I apologize tremendously for the delay in publishing the review of the GeekWold GK10S. Honestly, it’s not even the kind of review I would like to release but for total transparency, it should be published like all the others.


I particularly liked the GeekWold GK20 and they were very pleasant IEMs (I still have them and there are absolutely no complaints about them).


However, the review will still be 100% honest and, in no way, biased.


I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music.


So I’m not going to use super-technical words to review it, but I will do my best to describe it.

Tech Specs:​

• Driver: 1 balanced armature, 2 Piezoelectric ceramics and 2 Dynamic drivers
• Frequency:20Hz-40kHz
• Impedance:100
• Sensitivity:106dB
• Cable length:1.2M
• Headphone cable specification: 1.2m, 4 strands, oxygen-free copper, silver plated

Packaging:​

The packaging of the GeekWold GK10S is really basic. I can’t say she’s beautiful at all but that’s not what matters. On the accessories side, nothing is missing; in fact, we have:

• Carrying pouch
• Cable
• 6 pairs of tips

We can definitely say that the tips are not the best and a single set of BGVP 07 would have been welcome. These tips should become the basic standard, as they are very balanced and often work well. The cable is not bad at all—a 4-wire braided silver-colored one that is quite flexible.

Design/Build quality:​

At this price, obviously, the design is not very elaborate, the GeekWold GK10S shows off a look that resembles a heart, and the faceplates are not extremely beautiful but passable. The shell is made of plastic—nothing fancy but it’s comfortable and that’s what counts. On the shell, we can see two ventilation holes, one on the inside and the other near the connector.


They managed to put many drivers inside:

• 7mm graphene-plated DD for midrange
• 8mm titanium-coated DD for bass
• BA for treble
• 2 piezoelectric ceramic tweeters

If we think that the GeekWold GK10S is sold for 50 USD, the presence of so many drivers is really crazy. It is not clear how they can sell them for so little. Other brands for this money usually include a good dynamic driver, certainly not 5 different drivers. In my opinion, the problem is that they overdid it; if they had put in a few fewer drivers, the result would probably have been superior. It’s not just a question of how many drivers you can squeeze into one shell.

Comfort/Fit:​

The GeekWold GK10S are absolutely very comfortable and light. I did a 3-hour listening session without feeling any discomfort. I’ll leave you some photos of how they fit me.

Initial sound impression:​

When I put them on after a decidedly long period with the Kefine Delci, I felt a noticeable downgrade. We are discussing two IEMs with a preference for low frequencies, but there is no comparison between them. I literally threw away the original tips; I did not even try the tips with the narrow hole because the stage was already quite limited. I put the BGVP 07 on and saw some improvement, but nothing spectacular. They do not sound bad, but for all of the drivers present, they lack detail, brilliance, and are rather dark.

Faceplate

Final sound impression:​

Equipment used for testing above


Device:

• iMac
• Redmi Note 7 Snapdragon

Software:

• Tidal Hifi Plus (Mobile)
• Amazon music UHD 24bit 96kHz (Both)

DAC:

• LessFox Da2
• LessFox Da1 (neutral)
• F.Audio KS01 (bright neutral)
• Moondrop Dawn Pro ( Good choice but doesn’t help the tuning)
• Simgot DEW4X (extra refinement)
• EPZ TP50 (Audiophile combo)
• iBasso DC04 Pro (always good)
• Muse Hifi M4 (on-the-go option)
• Hidizs S9 Pro Plus (better mids)
• Fiio Ka11 (doesn’t help the tuning)
• Fosi SK02 (extra brillance)

After listening to it for the first time, I decided to let it run for a few hours at medium-high volumes.


Having read some reviews to see if what I felt aligned with other people’s opinions, I decided to also try changing cables.


There was an improvement by switching to an economical but balanced cable but a minimal variation was more dictated by the greater power or perhaps by the different DAC used. It doesn’t change noticeably.


What changes is how our brain receives sounds and the more I listen to them, the more I adapt.

Treble​

I must admit that the highs are far too smooth due to the presence of BA and Piezo drivers. They are certainly extremely tolerable but the lack of some spark quickly makes itself felt. The nasality of the tone is felt less in this region but overall it is also affected. The cymbals sound a little dull.

Mids​

Here comes the most painful note: they are recessed and invaded by excessive heat, which often makes the sound sound nasal. The bass bleeds into the mids and especially the male voices sound nasal. The instruments here, too, are slightly out of tune.

Bass​

There is really a lot of bass; maybe we are in the Bassheads area but the quality is not the best, and they are also a little lazy. But I still have to say that I enjoyed them, especially on deep house tracks. Unfortunately, the sparkling touch of the highs is missing and therefore the lows dominate the tone, making the IEM dark.

Separation/Imaging/Soundstage:​

The soundstage is quite intimate, and for the drivers it has, I would certainly have expected more but I imagine the problem is in the internal structure of the IEM, which will certainly not be very elaborate. As for the image, it’s not the best but it commands respect, but it lacks resolution and macro details. In terms of separation, it doesn’t do terribly well, but it doesn’t excel either. You must always consider that it is a hybrid IEM.

Fast Comparison:​

It is practically impossible to compare other hybrid IEMs in this price range. In this price range, we have an infinite number of single DDs with much higher technical performances. If prices go up, we will already start to see more concrete hybrids from Celest. We can say that GeekWold has proven its ability to create $50 hybrids.

vs Celest Plutus Beast or Phoenixcall​

They are both out-of-the-box IEMs with exotic configurations that have attracted the attention of many enthusiasts. It starts from the packaging up to the beauty of the shells. In both cases, I recommend you read my complete reviews but there is no comparison in sound quality or price. In my opinion, these are products with such a different concept that any comparison makes no sense.

vs Kefine Delci​

Beauty
Taking Kefine’s latest IEM, the Delci, as an example, we find ourselves with a single DD IEM (of excellent quality) with a CNC machined shell that is also of high quality. The package is well cared for and complete with accessories. In terms of sound, we have both an excellent low range that remains seemingly composed in its region without bleeding elsewhere and crisp, detailed highs. The midrange has the correct tone and also a more marked presence than that heard on the Gk10s. The rule of only one good and well-tuned driver is always valid.

vs EPZ Q5 & Simgot EW200​

If the single DD for bassheads is not for you but you are looking for something balanced, you can absolutely look at the EPZ Q5, which is fabulous and balanced with an excellent soundstage. If you want something with a more chic shell and a less problematic connector, then the Simgot EW200 is equally good but slightly inferior to the EPZ Q5 in terms of musicality and soundstage.

Conclusion:​

I thank Siyuan of GeekWold again for the opportunity to test one of their models. In this market segment, there is really too much to offer. On paper, the GeekWold Gk10s offer everything you need to have a well-sounding hybrid IEM but in reality, I would have expected more technique from a hybrid than a single DD. I think they wanted to be too daring by putting 5 drivers per side in a 50 USD IEM. Let’s be clear, it doesn’t sound bad but compared to the competition, it fails to stand out. The bass is very present and borders on the high frequencies, bringing out an L-shaped tuning. Unfortunately, the nasal mids and slightly subdued trebles don’t make it stand out in this price range. In any case, there is considerable potential in GeekWold products that I greatly appreciate.

Good morning to all readers! Today we try out EPZ’s new CS43131 dual-chip DAC. After trying the top of the line, the EPZ TP50, expectations are understandably high. Clearly, from my perspective, the market for dongles that mount the CS43131 has become extremely saturated. Unless power amplifiers or specific implementations are used, it is difficult to stand out among the crowd.

The review, as always, will be completely unbiased and uninfluenced.

I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.

My opinions are obviously subjective.

Tech Specs:​

• DAC: CS43131*2
• PCM: 32Bit/384KHz/DSD256
• Output power: 2vrms @ 32ohm 121mw (3.5) / 4vrms @ 32ohm 171mw (4.4)
• Signal-to-noise ratio: ≥125db (3.5)/ ≥130db (4.4)
• THD+N: ≤0.0008%
• Dynamic range: ≥125 dB (3.5) / 130 dB (4.4)
• Output:3.5MM/4.4M
• Weight: 25g (excluding packaging box)

Packaging:​

The EPZ packages have undergone very minor, purely aesthetic changes; as is typical, there are a few minor errors. This time, it is in the little manual.


However, when it slides open, we immediately see the TP20 Pro and its type C cable.


There is nothing else, and as I previously stated for the TP50, the USB adapter is also missing from the TP20 PRO.


However, I think the packaging is excellent; all that’s missing is the USB adapter. If we want to be extremely precise, perhaps we could opt for a cable covered in fabric to be more resistant. These braided cables are beautiful but much more delicate.

Build quality/First impressions:​

The new TP20 Pro now has a much lighter weight; the TP20 was a 55-gram block of cast aluminium, while the TP20 Pro has a much lighter CNC-machined aluminum shell.


The two faces are theoretically made of real carbon fiber, which gives it an almost more serious look compared to the TP50, which has a less serious aesthetic. The improvement from the previous model is obvious: a lighter shell and buttons that are more comfortable. As always, we have the physical gain switch, which is very convenient and easy to use and in addition to the volume buttons, we also have the play pause button. Obviously, the buttons also work on my iMac so the convenience isn’t just on mobile.



360 Overview

Power:​

In terms of power, absolutely nothing has changed but it is also excellent for driving some planar IEMs (on balanced output, obviously) or some IEMs that exceed 64 ohms. If you have more demanding loads, you have to increase the budget. No problems with the EPZ x Tipsy Star One or even with the Hidizs MP145.

Sound Signature:​

The question you are asking yourself is, “Has anything changed, or are we still dealing with the same dongle but in a lighter case?”


When I first connected to my iMac, I noticed that the USB interface was identical to the old TP20; essentially, the computer is unable to distinguish between them, so suspecting that it is the same motherboard is entirely legitimate and correct.


The operation is identical to that of most CS43131 DACs, so the only way to determine if there are differences is to disassemble both dongles and inspect each component individually. What I can assure you is that the TP20 Pro has far more resolution and refinement than the old one, which falls into the category of an old cirrus that is a little dark and has a stage that is not overly developed. So the TP20 Pro is undoubtedly better.

Fast Comparison:​

Donglemadness
For price reasons, I am not going to compare it with DACs equipped with the CS43198; they normally cost more and are slightly more refined in sound. So I will make comparisons with cheap dongles that use the same chip. More are coming out so there will definitely be something better in a month. Now under attention is the Fosi DS2, which has a remarkable output.

vs Moondrop Dawn Pro​

For price reasons, the Moondrop Dawn Pro remains in the entry level range, the dongle to beat. It’s cheap, it has an app, the buttons are a little loose but it also sounds very good (we’re already at the best version of the CS43131). Obviously, it has some cons in terms of aesthetics; the shell has holes and dirt or moisture can enter involuntarily.

vs EPZ TP20​

Currently positioned at 50 USD, in my opinion, it cannot compete with the Dawn Pro at the same price. Even though it is an excellent DAC, it lacks resolution, and the soundstage is not as developed. Its weight does not make it extremely suitable for use on the move without worries.

vs FiiO KA11​

Fiio Ka11
If balanced output doesn’t interest you and your priority is lightness and power, then the Fiio KA11 remains the best choice. I remain in love with this very small dongle. For someone like me who started with the ALC5686 with the same shape, having achieved such interesting powers in super-compact formats is remarkable. Of course, it sounds like the newer Cirrus Logics and has an accompanying app.

Who do I recommend this DAC to?​

Front Faceplate
If we start from the assumption that every 2 weeks a supposedly better product is released, I certainly wouldn’t be able to recommend anything to you. However, I would like to point out to you that it is not a race to see who comes out with the most power, but rather that we need the right balance between power and quality. Many manufacturers are starting to write only the power, omitting the THD, so we must not think only about the power but also look at our needs. A dual CS43131, even without dedicated OP amps, is more than sufficient for most of our IEMs. The EPZ TP20 Pro is an excellent dongle on par with the Moondrop Dawn Pro; aesthetically, the TP20 Pro is more resistant, the carbon fiber is beautiful, and the app is missing but honestly, I don’t use it that often, even where it is available. When one can fix the gain, he is already a happy man. Excellent when combined with bright IEMs to slightly reduce peaks, or to add thickness to IEMs that are already rich in bass. Congratulations to EPZ for bridging the gap with its competitors.

Good morning, readers! It is time for Kefine Delci!


Today we are going to talk about a new brand called Kefine, which is a SIVGA subbrand. Their first IEMs were planars at a very low cost. If you are interested, I recommend you take a look at the KEFINE Klanar.


The brand new ones are called Delci and are a single DD IEM with an excellent quality-to-price ratio. Their goal is to provide high-quality products at low prices, and they appear to be successful.


Thank you, Kefine, for sending me this unit to review.


I am not an audiophile; I am just a guy who enjoys trying out different IEMs and DACs and spending a lot of time listening to music.


So I will not use super-technical terms to review it, but I will do my best to describe it.

Tech Specs:​

• Driver type: 10mm DLC + PU
• Frequency response: 20 Hz–20K Hz
• Sensitivity: 108 dB +/- 3 dB
• Impedance: 28 ohm +/-15%
• Plug size: 3.5mm SE
• Shell: CNC-machined aluminum
• Weight: 5.3 g for one side

Packaging:​

The new packaging is noticeably more refined than the previous version. The Kefine Delci arrives in a very fine and elegant package, and this time it is well-equipped with accessories.


Inside, we find:

• A nice cable (only present with 3.5mm termination)
• 2 types of tips (7 pairs)
• A rigid case for transport

Finding a nice cable, absolutely high-quality tips, and a case for such a well-made IEM is truly impressive. The price is only 59 USD, and I do not recall seeing other IEMs with such a comprehensive package. KEFINE has surprised me because, despite being new and unknown, they have managed to keep their prices low. I would have preferred to be given the option of selecting a balanced cable; not much power is required, but a DAC/AMP is extremely beneficial.

Design/Build quality:​

The Kefine Delci has a particularity compared to the competition, namely that the shell is not obtained from a mold but is CNC machined from aluminum blocks. In this way, the shells are extremely light and, above all, resistant; furthermore, the gunmetal finish should not present defects over time.


The design vaguely recalls those of the Klanar; the brand is on the faceplates and is clearly visible but not invasive; the shape of the shell is very ergonomic and, above all, compact; in terms of size, they are approximately the same as the Simgot EW200. In the part facing the inside of the ear, we have two ventilation holes; the rest is all sealed.


These types of shells are usually seen on higher-cost IEMs; the same is true for DLC + PU drivers.

Initial sound impression:​

I noticed right away how similar the overall sound was to Klanar. They decided to stick with the same V-shaped philosophy (staying safe), which I like. If the Simgot EW200 or EPZ Q5 are too bright for you, this IEM could be the solution. As a very first test, I connected the Fosi SK02 to it and I will tell you that it wasn’t bad at all; it was actually a bright and powerful source with a warm IEM.

Beauty
I gave it a quick listen, focusing primarily on the very full-bodied and energy-rich bass (a slight pressure in the ear canal is felt), and I noticed a very good soundstage. I began with a deep house playlist, and if the track requires a lot of bass, the Delci pushes extremely hard; in my opinion, it enters basshead territory. However, it manages to maintain a high level of detail in the trebles, with a hint of air.

Final sound impression:​

Equipment used for testing the above

Device:​

• iMac
• Redmi Note 7 (MIUI-Based)
• Poco M4 Pro

Software:​

• Amazon music UHD 24bit 96kHz
• Tidal Hifi Plus

DAC:​

• Moondrop Dawn Pro ( Good choice)
• Simgot DEW4X (extra refinement)
• EPZ TP50 (Audiophile combo)
• iBasso DC04 Pro (always good)
• Muse Hifi M4 (on-the-go option)
• Hidizs S9 Pro Plus (better mids)
• Fiio Ka11 (great pairing)
• Fosi SK02 (extra brillance)

After performing a bit of burn-in as usual, whether I needed it or not, the Kefine Delci immediately sounded good and I didn’t notice any extra improvements.


I started trying different dongles and some led to some improvements, especially in terms of depth. I personally stopped on the Fiio Ka11, which has excellent synergy with the Delci. The soundstage has literally opened up compared to the Creative Sfxi Amp; perhaps the greater power of the KA11 or simply the amplification stage, is more refined.


Of the original tips, I liked the wide-bore ones as usual, but it’s definitely a set that deserves some rolling tips.


The shells for my ears are decidedly small but in reality, it is not a problem at all, as you have more positioning possibilities and, above all, greater possibilities with different tips.


Kefine certainly got this model right, and I think many will like it.

Comfort & Fit:​

If you have large ears, they may be small, but they should not cause you any problems. If you want them to be more external, consider getting tips like the DUNU S&S or Tri Clarion. In the photos, I am wearing Tri Clarion tips in size L.

Tips Rolling?​

The originals are fine; you don’t necessarily have to buy other tips like on similar sets, but since I have a lot of tips to test, I decided to try playing with them a bit.


Divinus Velvet: I don’t know how but they are universal; any IEM I pair them with makes sense. In this case, they slightly reduce the bass pressure in the ear canal while keeping the sound almost unchanged. There are some small improvements in the high frequencies.


DUNU S&S: What a pleasure, Excellent combination. The Delci have a slightly short nozzle so even if the Dunu are a little longer, they don’t create any problems. Improved soundstage, slightly softer bass, and a slight recovery of medium and high frequencies.


Tri Clarion: If you want to keep your budget low, these tips are great on the Delci, and I honestly do not notice any loss of bass; in fact, because they are so wide, they do not compress the sound, and they keep the soundstage open. Excellent comfort.

Treble​

Kefine Delci managed to maintain a certain brilliance on the high frequencies, although they remained in the safe zone. The driver has sparks, brightness, and even a bit of air. There is energy but even the most sensitive can tolerate it. The macro details are present and I would say that even some micro details manage to emerge. I was greatly surprised by these controlled trebles.

Mids​

In terms of mids, I thought they were much more recessed. Although they are not protagonists, they are particularly natural and well represented. The mids feel thick, silky, and rich. Vocals are pitch correct but not tonally neutral. It’s an IEM that focuses a lot on the fun factor without losing too much seriousness. Excellent both male and female voices. Cymbals and musical instruments sound vivid and full of energy. There is a certain musicality.

Bass​

Kefine has a decidedly heavy and abundant hand. The bass has great emphasis, transporting you to the dark side of the bass as soon as the track calls for it. I must say that they are fast and well defined for the quantity.


The subbass doesn’t have much roll-off and overpowers with harmony. I would describe him as nice, rich, and thunderous. Despite its weight, the driver manages to maintain a certain level of control even through complex tracks. If you are looking for something neutral, this IEM is not for you.

Soundstage and Imaging​

Both the driver and the CNC-machined shell have resulted in accurate acoustics, and the soundstage is decidedly wide for the average. In this price range, I hadn’t yet tried the IEMs that Bassheads would like so for 59 USD, they are truly amazing. The image is very good, in some cases, it loses a bit of resolution but overall, it is really well done from several points of view.

Comparison:​

vs EPZ Q5 & Simgot EW200


I have grouped them together as they are not comparable as they aim at two user targets that, in my opinion, are different. Here we are talking about very high-value IEMs, characterized by a bright and detailed sound signature. The bass sounds more natural and overall, it is less fun-oriented than the Kefine Delci. I can say that Delci easily competes with them but in the bassheads category.


vs EPZ x Tipsy Star One

Front & back
The EPZ x Tipsy are the ones we can compare the most in terms of musicality. The Tipsy driver is 64 ohm with excellent scalability and is characterized by a totally dark background that highlights the track in the center. The shell is made of resin (with handmade details), and the accessories included are a little scarce for the cost but I must say that it still has something that makes me buy it. A slightly more balanced sound is characterized by less emphasis on subbass and a slightly more natural sound.

vs Kefine Klanar​

I was forgetting to compare them with the Kefine Klanar; the planar driver has a much less accentuated but still very strong bass and sub-bass. If you have the opportunity to purchase both (both are excellent and cheap), you will notice how the DD provides a fuller bass, perhaps a little slower. The mids feel less recessed, and macro and micro details come out more easily from the tracks. It has another level of definition and resolution. However, it is noticeable that they come from the same brand, even if this is slightly more balanced.

Conclusion:​

Kefine is proving to be a brand that knows what it’s doing, and despite following a safe path, the results are still worthy of note. The Kefine Delci enters the Simgot and EPZ markets, targeting the segment that loves full-bodied basses. The bass also has a lot of pressure in the ear canal; my left ear has become particularly sensitive to moving air so I’m pretty confident. If you are sensitive to the acoustic pressure exerted in the ear canal, these are certainly borderline; however, if bass & subbass is your secret love, this IEM will certainly be a joy. For 59 USD, you get a complete IEM, full of well-made accessories, a very light and robust CNC-machined shell, and a DLC + PU driver (more expensive than an LCP).


Congratulations to Kefine, who is following a decidedly successful path. Thanks to Collin Yang for sending me this unit to review. I am delighted with it and it will stay with me for future comparisons.

Good morning, readers! Today I will talk about an IEM that has already had a lot of success. It is a little late to ride the wave, but I am happy to share my thoughts. Thank you, as always, to Betty at Simgot for providing me with the Simgot EW200 unit to review. I am waiting for the EA500LM and EA1000 to arrive before I can fully understand Simgot, but so far, the EM6L and now the EW200 follow a sound concept that I particularly like.


As always, I remind you that I am not an audiophile, but rather an enthusiastic participant in this hobby. It is not my job or a source of income. So far, I have not sold any products.
The review will be truthful and honest.

Tech Specs:​

• Driver: 10mm dual-magnetic circuit & dual-cavity SPC dynamic driver
• Diaphragm: double-sided vapor-deposited silicon crystal diaphragm
• Impedance: 16 ohm +-15% (@ 1kHz)
• Sensitivity: 126dB/Vrms (@ 1kHz)
• Frequency Range: 10Hz–50kHz
• Frequency Response: 20Hz-20kHz
• Connector: 0.78mm
• Cable : high-purity silver-plated OFC cable

Packaging:​

Accessories
For the price range in which it is positioned, the Simgot EW200 has a very respectable package. Definitely very elegant; not too complex but the presentation is excellent. Inside, we immediately see the EW200, which looks amazing.


As accessories, we find:

• The cable
• Tips
• Carrying pouch
• Manual and QC

The cable is not excessively thin; in fact, it is perfect for maintaining maximum comfort and is, above all, soft. The tips, on the other hand, absolutely do not do the IEM justice. My advice is to buy different tips directly.


It’s not a problem anyway; often the original tips are quite cheap but perhaps you could have opted for SS20 or 07.

Design/Build quality:​

The Simgot EW200 wins quite easily. The material and mirror finish please the eye. They are beautiful and well built for my personal taste; they are really beautiful, especially when coupled with a silver cable. As we can see from the shell, we find two holes for driver ventilation, which actually seems to be of high quality. It uses a particular SCP membrane, which should give a hybrid combination compared to the results of the DLC and LCP membranes.

“The EW200 utilizes a revolutionary diaphragm material – the SCP Diaphragm. This diaphragm incorporates a special polymer film as a substrate that is coated with a hybrid silicon layer through dual-sided sputtering deposition. By combining the strengths of DLC and LCP diaphragms, it maintains the high-density mid-range performance of LCP diaphragms and the extended, exquisite high-frequency response of DLC diaphragms. Additionally, it overcomes the challenges of high-frequency control and slight harshness found in some audio sources with a DLC diaphragm, resulting in a luxurious and smooth sound with rich layering and spaciousness. The diaphragm is further enhanced through specialized molding techniques and precise material blending, optimized to deliver a full and textured low-frequency response, a natural and dense mid-frequency performance, and a detailed and splendid high-frequency reproduction. With the powerful driving force of the dual magnetic circuit and dual cavities, the diaphragm and magnetic chamber achieve a harmonious balance, thus enhancing overall performance.”

Indeed, the sound performance is fantastic, and together with the EPZ Q5, the entry-level range has really become competitive. Continuing to observe the shell, thanks to my macros, you will notice that the assembly is excellent, the finishing is excellent and the writing on the faceplates is very fine. An IEM that I would also aesthetically define as HI-RES.

Initial sound impression:​

Lately, I’ve been seeing a lot of people calling them “shouty,” so I was a little worried but in the meantime, I was listening to the EPZ Q1 Pro and from a quick comparison on Squiglink, I noticed they were much brighter. Since the EPZ Q1 Pro is anything but shouty, sibilant, or harsh, the Ew200 couldn’t have been worse. I connect them directly to one of the brightest sources I currently have and am immediately impressed! Less than $50? Truly? It’s true that a single DD expertly tuned is better than 4/5 that aren’t perfect.


The EW200 vaguely reminds me of the EM6L; they have 1/3 of their musicality and energy. I take the original tips and replace them with Whizzer SS20s and they get even better. I haven’t changed its cable, as I already consider it perfect. But if I were to find a good offer for a silver OFC, I could definitely think about it. This Simgot EW200 will remain with me anyway.

Comfort & Fit:​

The Simgot EW200 has a fairly small shell; they are heavier than some resin ones as they are probably obtained by casting and not by CNC machining but the shape with the right tips will not give you any trouble. I’ll leave you some photos.

Final sound impression:​

Equipment used for testing the above


Device:

• iMac
• Redmi Note 7 (MIUI-Based)
• Poco M4 Pro

Software:

• Amazon music UHD 24bit 96kHz
• Tidal Hifi Plus

DAC:

• Moondrop Dawn Pro
• Simgot DEW4X
• Hidizs SD2
• EPZ TP50
• iBasso DC04 Pro
• Hidizs S9 Pro Plus
• Fiio Ka11
• Fosi SK02

I let him run for a few hours of burn-in, although I think my brain just got used to it quickly. Coming from the review of the EPZ Q1 Pro, I was already used to something bright; the EW200 is audibly less bright; they have thicker notes; in terms of details and soundstage, I think the EW200 is capable of being slightly superior but the credit probably goes to the driver with the SCP membrane. In terms of shades, I would place them between the Q1 Pro and the Q5. The timbre is very natural and not at all fatiguing, and the resolution and clarity are truly excellent.

Bass​

The bass has more kick and push than the Q1 Pro but the difference is not overly marked unless the track requires it. The bass is really precise, with excellent speed and quality. Let me be clear: this is absolutely not for bassheads.

Mids​

For personal taste, I find them perhaps superior to those on Q1 Pro, probably due to the depth of the voices. In both, we are at very high levels. Female voices have consistent silkiness track after track and musical instruments have energy and detail while maintaining a natural timbre. In some cases, it lacks a bit of depth and emphasis and some voices sound slightly thinner than they should. But the musical instruments are especially correct.

Treble​

If you are sensitive to this region, you have landed on the wrong review. In my opinion, they are bright but far from harsh, shouty, or sibilant. There are those who describe them with some adjective like that; I imagine they are simply not very tolerant of certain frequencies and amounts of brightness. The crispness of the highs and energy is overwhelming; for some, it may be too much.

Tips Rolling?​

The included tips don’t do it justice; the quality itself is good but the closed nozzle limits its soundstage and performance, in my opinion. If you don’t want to spend a lot in the AliExpress Choice section, you can find the Tri Clarion, SS20, or 07 (under different brands). You could get all 3 types for over $10.


Obviously, the Divinus Velvet tips are also extremely good but I want to keep the final cost low. The Dunu S&S are slightly cheaper but I didn’t find them particularly comfortable with this set.


I immediately found total comfort with the Whizzer/KBear SS20, which has a wide bore.

Soundstage and Imaging​

I would say that in this price range, they are truly stunning. We are faced with an IEM that has everything that someone who wants to enjoy a bit of high resolution could be looking for: the image is very sharp and precise, and the soundstage is sufficiently wide (even above average) in all directions without being too distorted from reality. They are the kind of single-DD IEMs that immerse you in the sound and make you enjoy the quality of your favorite tracks.

Comparison:​

Endless comparisons could be made but I will limit myself to those that come most naturally given the price range. If you have any particular requests for comparisons, please feel free to comment.


vs EPZ Q1 Pro

So Beautiful
If the EW200 is not bright enough for you, you can get the EPZ Q1 Pro, which further enhances the brightness without being sibilant or shouty. They are monsters of clarity and are also particularly beautiful to look at. Yet another successful model from EPZ that could satisfy some trebleheads. I would recommend reading the entire review.


vs EPZ Q5


The EPZ Q5 is the direct competitor of the EW200. Both are entry-level destroyers that leave very little room for the competitors in this price range. What I can say about it is that the Q5 has a slightly warmer tone in the mids so the overall perception is a slightly warmer tuning with a slight extra weight on the notes. The bass is slightly thicker. The trebles are slightly calmer but plenty of detail and air remain. The soundstage, being half open-back, is even bigger. Two truly excellent IEMs. Maybe the Q5 has that extra magic touch, although that MMCX may be an Achilles’ heel.


vs Tiandirehne Se846 (hidden gem)


An IEM that I have yet to find the time to review as I consider it a hidden gem. This DD thrown into a Shure-like shell (pretty cheap materials) sounds ****ing good. They sound 88% like the Q5 but the price is absolutely crazy. We are around 26 USD with cable, some good tips, and a case. Here, you only pay the price for excellent sound. They are a little less brilliant, they lose some points in image and layering and above all, the soundstage is not as developed as on the Q5. Compared to the Simgot EW200, the sound is less musical but warmer. They are a successful experiment. Seeing is believing!

Conclusion:​

I finally understand all the hype built around the Simgot EW200; I can only confirm it. For those who judged them to be shouty, the only reason is that you are not very tolerant of high frequencies.


Although it is bright, I mostly tested it with fairly bright DACs to see if they are as shouty as some users claim. I can assure you that I have had no issues with either the Fosi SK02 or the EPZ TP50. The DEW4X is slightly more balanced/neutral than the other two and pairs exceptionally well with the EW200. If there was a deal for this combination, I would consider it.


Hearing differs from person to person in this hobby, and age also plays a role. The Simgot EW200 follows the very brilliant Harman curve, resulting in a very energetic, musical, and detail-rich IEM that did not previously exist at this price. The EPZ Q5 followed, which improved a few minor aspects.


Given that the Simgot EW200 has been on the market for a while and continues to impress, the hype surrounding this set is entirely justified.


My heartfelt congratulations to Simgot for making this hobby accessible to anyone with an IEM like the EW200.

Good morning, everyone! Today we’re going to see the new EPZ DAC together! The EPZ TP50 was sent to me by EPZ with a discount. I thank them for this opportunity to test their products.


This is the second DAC I own that features a dual Cirrus Logic CS43198; the first was the Simgot DEW4X. Obviously, comparisons will also be made with the old EPZ models.


EPZ seems to be constantly in the spotlight these days, but I believe he deserves it. After several excellent IEMs, the new DAC/Dongles have finally arrived. I am delighted to have the chance to review them for you.


The review, as always, will be completely unbiased and uninfluenced.


I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.


My opinions are obviously subjective.

Tech Specs:​

• DAC: 43198*2
• Power amplifier:RT6863*2
• PCM:32Bit/768KHz/DSD256
• Output power: 2 vrms @ 32 ohm 125 mw (3.5) and 4 vrms @ 32 ohm 240mw (4.4)
• Signal-to-noise ratio: ≥125db (3.5)≥130db (4.4)
• THD+N: ≤0.0005%
• Dynamic range: ≥125 dB (3.5) 130db (4.4)
• Output:3.5MM/4.4MM
• Frequency response:20HZ-80KHz
• Volume control: DAC volume
• Display: Oled
• Weight: 28g

Packaging:​

The packaging of the EPZ DACs has remained almost unchanged. The EPZ TP50 packaging is excellent; it is a very rigid cardboard package that protects the contents very well. Some extra detail has been added in terms of graphics. As you may notice, there is a small error in the description on the packaging; it is reported as dual CS43131. Unfortunately, the first batch will have this error on the packaging and something else in the instructions.

• Small manual (where the menu functions are missing and the instructions aren’t for this dongle)
• Type C to Type C cable

On a similar DAC, I would have expected at least a USB adapter, unfortunately it is missing and you will have to get one if your PC does not have type C. The menu functions are missing in the manual but luckily they are there on the product page on AliExpress.

Build Quality/First Impressions:​

Compared to the old TP20 and TP30, the leap in quality is truly remarkable. The first ones were well made but very heavy, not too comfortable attached to the type C of the phone. These are finally lighter. The EPZ TP50 has the same dimensions as many other DACs (it is not as compact as the Simgot), the shell is made of metal, the faces have a sort of panel that resembles a carbon texture with blue inserts and in the front part we find the screen OLED (a real gem). The general quality is very good, perhaps I would have preferred to see a 3.5mm output in metal rather than plastic but all DACs are like that.


As for the included cable, I find it to be of good quality, although I see this type of cable as more suitable for IEMs. A cable like the one seen on Simgot that is covered in fabric might be more durable.

No App? No Problem!​

This is the first DAC that, despite not having a dedicated app, doesn’t really need one. From its small display, you can adjust any setting from a sort of secret (not so secret) menu. By holding down the M button, you enter the system menu with the following options:

1. LEVEL: Volume control during music playback, such as adjusting the volume level of music. It can also be used to describe the sound quality of an audio signal, such as adjusting the level of bass or treble.

*In reality, in the LEVEL menu, it simply adjusts from LOW to High Gain

1. ADJ-L/R: Balanced left and right channels.
2. FLT: Output the input signal in single-ended form. It means using single-ended output to achieve amplified audio effects.

*FLT are just digital filter options.

1. DAC OM: is an output mode that converts digital signals to analog signal output to provide a listening experience closer to the original audio signal.

*I can’t hear any differences here.

1. S/PDIF: A digital audio interface jointly developed by Sony and Philips. It is a series of protocol and technology standards. It is widely used in digital signal transmission between current CD, DVD, DAT, VCD, MP3 players, and other electronic devices. (Sony/Philips Digital Interface Format)
2. H-DEPOP: is a circuit used to eliminate unwanted crackles or clicks in a circuit, often quantified in terms of “pop performance”. (High Dynamic Range Anti-Crackling/Suppression Circuit)
3. DISP BN: Display brightness.
4. DISP ROT: 180° rotating display
5. OFF-DISP: Screen lock duration.
6. HID KEY: Some or all of the amp’s settings will be hidden or locked to prevent unauthorized changes. This allows users to focus more on the listening experience without having to worry about misoperations. (Avoid misoperation)
7. UAD FW: The meaning of firmware of Unified Audio Device Driver. UAD FW is the software running inside the headphone amplifier, which is used to manage and control various functions and parameters of the headphone amplifier. By upgrading UAD FW, users can get the latest features, fix known bugs, and improve headphone amplifier performance and stability. (Version)
8. RST DEF: Restore factory settings.
9. Button control: Press the M key twice to light up the screen, long press the M key to enter function switching, click +/- to increase or decrease the volume by 1 (0-100), and long press +/- to continuously increase or decrease the volume.
10. Switch between previous and next songs, pause: After the HID KEY switch is turned to ON, the M key is for pause/play, click the + sign for the previous song, and click the – sign for the next song. After turning on the HID KEY switch, the +/- keys cannot be clicked to adjust the volume, but can be adjusted by long pressing.

Take a look at my 360 + Setup Menu Reel!​

360 + Setup Menu

Power:​

The EPZ TP50 has excellent output, both on PC and smartphone, but the volume remains almost unchanged. It keeps the volume in memory, and above all it is independent with 100 volume levels, which, together with those of the connected device, are almost double. The anti-pop function is very interesting, although lately many are including it, it allows you not to hear those very annoying pops when connecting or disconnecting the DACs and also during playback.

Outputs side3.5mm plastic and 4.4mm metalClose look to the buttonsFaceplate close lookNice reflections
As for the declared TP50 data, I can’t tell you if they are reliable; theoretically, it should be less powerful than the Simgot DEW4X but they both seem to be on the same level. The EPZ TP50 has a double CS43198 chip coupled with two RT6863 OP-Amps; some values seem a little low to me.


The test is carried out with the maximum volume on the DAC.

Test of the SE 3.5mm with 121 mW at 32 ohm:​

• Simgot EM6L, no kind of problem obviously so I added a 75 ohm impedance, which allows me to reach the maximum volume but the sound pressures are still quite high.
• Epz Q1 Pro with a 75 Ohm adapter, the sound pressure is still excellent. I would say that for most IEMs, they will have no problems. Just keep under 100 ohm.
• Celest Plutus Beast being less bright, you can push yourself to higher volumes. Great pairing.

Testing the BAL 4.4mm with 240 mW at 32 ohm:​

• Hidizs MP145 There is all the power needed to make them express themselves at their best. I have to say the pairing with warm headphones or IEMs is particularly notable. There’s some extra sparkle in the trebles.
• Letshuoer S15 is pretty similar to the MP145 in terms of needed power.
• EPZ x Tipsy Star One, which I finally put on a balanced cable, expresses its best with this analytical and luminous signature. There are no driveability problems. 3 bars out of 16.
• EPZ Q5 For them to be balanced, very little volume is needed from the device to which the DAC is connected. 1/2 bars out of 16.

Sound Signature:​

It appears that the CS43198 DACs are much more analytical than expected! I can say that they follow the same path as the Simgot DEW4X, but it is difficult to say that they are Cirrus Logic, which is known for its warm sound. This produces a relatively cold sound but works well with a variety of Harman curve IEMs. I must admit that having similar DACs is extremely beneficial to me when reviewing. Many have different sound colors and in some cases, unwanted colorations are added. I know some will think that a good DAC should be neutral but almost all of them have some implementation that doesn’t make them so. As far as digital filters are concerned, they really work, and the changes are noticeable even if, obviously, they don’t overwhelm. A PEQ is actually missing; adding a menu where you can adjust bass, mids, and treble would be great.

Fast Comparison:​

Donglemadness

vs iBasso DC04 Pro


Despite the CS43131 chip, he has a definition that few have achieved until today. iBasso has always been the benchmark in terms of successful CS DACs. The OP-AMP section is probably well finished and of good quality. The soundstage and image also benefit.


vs Simgot DEW4X


Simgot DEW4X has an extremely compact shell, is theoretically even more powerful on paper and goes well with any IEM. Slightly less cold sound but still tending towards neutral. It has a more affordable price but fewer options as it lacks both apps and displays.


vs EPZ TP30


The TP30 could have some chance if it were to drop in price. Currently, the price difference between them is only 20 USD, which is a bit small considering the features of the TP50. I must say that the TP30 is even less analytical and slightly warmer. It serves as a compromise. It would re-enter the market if its price fell.


vs EPZ TP20


The TP20 is now outdated, characterized by a mostly warm sound and now has several opponents, such as the Moondrop Dawn Pro, which is currently, together with the Fiio Ka11, the first choice for newcomers to the hobby. I’ll leave you with the full review.


vs EPZ TP20 Pro (coming soon)


The TP20 Pro is recognized by my iMac in the same way as the TP20; the USB interface is the same without customization but regarding the sound, it sounds more similar to the new Cirrus CS43131. This, given the good aesthetics and the price, can compete against the more recent ones. The full review is in progress.

Who do I recommend this DAC to?​

The EPZ TP50 raises the bar for the CS43198. Before, the TP20 and TP30 seemed outdated; now, with the new TP50, we find ourselves at the forefront again. The CS43198 + Op-Amp RT6863 configuration is a nice combination but the addition of the display is absolutely the coolest thing about this DAC. Despite the absence of a dedicated app, the display makes up for this lack. I will tell you that intervening directly from the display is much faster and more immediate. Personally, I find it really comfortable. The only DAC with a display I have is the F.Audio KS01 but I couldn’t change settings on that one.


The tone of the TP50 is actually tending towards cold, much more analytical than expected and goes divinely with warm IEMs. Together with the DEW4X, the TP50 is one of my current favorite DACs. I would have liked to see at least one USB adapter in the package, like the one present in the Simgot. The same thing goes for the menu instructions, which are only present on the AliExpress page. Some points are not even very clear to me, such as the OM DAC setting, where I don’t notice any differences.


But, to be honest, it is a fantastic DAC/dongle, complete with (functional) digital filters and a nice display to manage it.

Good morning, readers! In this review, we will analyze Fosi Audio’s latest product. I thank Hifigo, who, together with Fosi Audio, sent me this Fosi SK02 unit to review. I needed something more powerful and this big dongle/AMP has a lot of power.

By now, the quantity of Dongles in my possession has reached a considerable amount. I don’t consider myself a foreigner but hopefully you like my review and find it useful.



The review, as always, will be completely unbiased and uninfluenced.


I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.

Packaging:​

The box is very simple; I’m not even sure that it is the final packaging of the product, as it was sent to me before the end of the Kickstarter. As you can see, it is not tailor-made. Inside, we find the Fosi Audio SK02, the cable with an integrated USB A and Type C adapter (a magnificent accessory), and the manual.


I don’t know the final price yet but theoretically it should be under 100 USD, I think the set of accessories is correct.

Build quality/First impressions:​

Even before opening the package, you can feel its weight. It is certainly not a dongle. Opening the box, its size is immediately apparent; the body is entirely made of aluminum alloy, painted black in a matte finish. The volume knob is also a solid block of aluminum. The peculiarity is that it runs infinitely and allows precise volume adjustment (it has a memory of the settings). The knob also has the function of being pressed and is used to mute, play, or pause.


On the front, we have 2 more buttons, one for the gain and the other for the input mode.


As you can see, the front panel is full of LEDs that indicate the gain. the sampling rate, the input, the power status, and even the volume (or power) level.


In fact, next to the audio/speaker symbol, there is a purple and blue LED that indicates the right and left channels and lights up when the power demand becomes important. Obviously, it lights up to the rhythm of the music. Here, it would have been nice to see two series of LEDs with the musical spectrum, perhaps in the next product.


On the front, we have the two outputs, 3.5mm and 4.4mm balanced, both very powerful.


In the back, we have double input, optical and USB, but also an AUX output if for example, you wanted to use an AUX to RCA cable to connect a speaker amplifier. This output also has optical functionality but its operation is not explained very well, You need a 3.5mm optic cable and in my opinion, it always acts as an audio output so you can connect it to a home theater or a soundbar.


However, it is an extremely versatile product and despite its size, we can also consider it portable as it does not require external or extra power supplies.


Qualitatively speaking, the construction is well taken care of and the assembly is free of defects.

Power:​

In terms of power, considering that it does not require an external power supply, it is a little monster. On the 3.5mm output, we have 280 mW at 32 ohms, which I assume is per channel, This is because, compared to the FiiO Ka11, the volume is much higher. I connected the Hifiman Deva Pro to it with only 18 ohms and it is impossible to reach the maximum volume. The power is sufficient for most headphones and IEMs already on SE output.


On the balanced output, we have 1100 mw at 32 ohm, which I would say are per channel (I have to check with Fosi) but they could easily be the summed values. But seeing the power in the SE of the FiiO KA11, I don’t think it can develop less power. Also because the volume is significantly higher.


Needless to say, it has no difficulty with any IEM or headphones. I don’t have anything with extremely high impedance but I will soon be looking for something with at least 300 ohms.

3.5MM​

For the moment, the heaviest test I can do on a 3.5mm output is the EPZ x Tipsy Star One 64 ohm + adapter with 75 ohm impedance.


I can tell you with certainty that it is not affected in the slightest. Obviously, I have to turn the volume up more but it is still not possible for me to reach the maximum volume. I don’t think you would have any problems with 300-ohm headphones as long as they have good sensitivity.


The Hifiman Deva Pro on 3.5mm seems connected to a balanced output (they also have an impedance of only 18 ohm).

4.4MM​

On balanced 4.4mm output, I have tested all the planars in my possession. As far as IEMs are concerned, it doesn’t have any kind of problem. The KZ PR2 V2, which is the least easy to drive, will likely explode if I try to reach maximum volume. The driver can’t even keep up with the power. As for Hidizs MP145, Letshuoer S12 Pro & S15 and Kefine Klanar, they are managed without any kind of problem.


The Hifiman He400Ses, on the other hand, definitely benefits from the extra amplification. The driver acquires dynamics that I don’t notice with other balanced outputs, including improved soundstage and bass with greater impact.

AUX OUT:​

Given the somewhat particular functioning of this AUX, I asked Fosi for clarification.


I noticed that this output is also amplified and the volume is always controlled via the knob. Theoretically, I would have expected a classic AUX output like I have on my FX AUDIO DAC X6 that I connected to my speaker amplifier. Connecting two amplifiers in cascade, as my colleague Sean pointed out, is not a big deal. Practically, we could also connect headphones to the rear audio output. Now it remains to be understood whether it can also be used at the same time (I doubt it). Furthermore, it is also an optical output and this works normally; we can connect a home theater or any audio system to it.


Update from Fosi Audio:


The rear output has very low amplification and can be used together with the balanced output without problems. I would say that in this case, you can use the output on the back to connect it to a speaker amplifier without any problems. I personally won’t use it that way, as I already have another DAC. The Fosi is extremely convenient for me for headphones and IEMs.

Test/Sound Signature:​

Like all the DACs that use the same chip in my possession, the Fosi SK02 is also characterized by a bright sound. It’s not the brightest but it definitely doesn’t have warm undertones, in fact, if a headphone/IEM is warm, it tends to make it more balanced. You may or may not like this feature but personally, I don’t experience any kind of problem, on the contrary, it doesn’t place an emphasis on the low range like some Cirrus logics. However, in the case of the Hifiman He400Se, the greater amplification gave body to the bass.


So I presume synergy also comes into play, even if it is rare and in some cases, the performances may differ from expectations.

Even the Tanchjim Zeros connected to it demonstrate a certain amount of bass despite being bright.

As far as I’m concerned, the Fosi SK02 will remain on my desk as a neutral, bright, and powerful reference. For a little more analytical and critical listening, it seems suitable to me.

The Fosi Sk02 works differently depending on what I plug it into. On my iMac, I can play-pause tracks, while on my smartphone, I can only mute them. On the iMac, the volume can only be managed by the SK02, while on a smartphone, you have double adjustments. In both cases, it works perfectly, demonstrating high performance even from type C.

Fast Comparison:​

vs iBasso DC04 Pro

iBasso DC04Pro
iBasso DC04pro has something more than the others; they may be small things but although the chip is identical to that of the Moondrop Dawn Pro, the OP-Amp department is evidently more refined. I don’t think the price difference is just a matter of brand but to be sure, they would need a teardown. It comes across as more musical and refined, with a soundstage that sometimes seems wider. The Fosi SK02 is brighter and, in any case, much more powerful and practical for desktop use.


vs Hidizs S9 PRO Plus

Side
Hidizs S9 Pro Plus has its own sound coloring in the DACs. There are those who might think that it is a negative factor but the difference is that even if it doesn’t upset you on some IEMs, it is more noticeable. The sound is slightly warmer and focused on the vocals. It somehow makes even trebles smoother without losing detail.


vs Moondrop Dawn Pro

First look Moondrop Dawn Pro
This is an excellent entry-level DAC that allows everyone to get close to the balanced output. For the asking price, the Moondrop Dawn Pro is definitely the right choice. In terms of sound, it is warmer than the Fosi SK02 but not too much.


Vs Fosi K5 Pro

Fosi Audio K5 Pro
I’ve reviewed it elsewhere so I’ll put a friend’s review in the link. The Fosi K5 Pro is certainly a much less serious DAC, the difference is noticeable but it has the convenience of being able to adjust the highs and lows. This feature is great and would have been very useful on the SK02.

Who do I recommend this DAC to?​

Like all the DACs that use the same chip in my possession, this one is also characterized by a bright sound. It’s not the brightest but it definitely doesn’t have warm undertones; in fact, if a headphone/IEM is warm, it tends to make it more balanced.

Packaging:

Hidizs SD2 has less elaborate packaging. We do not find the classic rigid plastic packaging but a cardboard package. However, the packaging is quite neat but what is surprising is the standard equipment of the small dongle.



Once opened inside, we find the DAC embedded, and below we find the accessories:

- USB A adapter

- Type C to lightning

- Manual + QC/warranty


Build quality/first impressions:


At first glance, I would dare say that we are faced with a slightly cheaper product than what we are used to with Hidizs. The Hidizs SD2 comes with an extremely particular "Mecha" design. The two faces appear to be made of metal, while the body is made of plastic, or, I would say, solid construction.

The design intrigues me, but at the same time, it makes me think that it could put a strain on the type C sockets. Both the shape and the angle of the headphone jack create important levers on your type C sockets. In any case, we can define it as the successor to the Hidizs S3 Pro. If it weren't for the design, it would be very difficult to distinguish them in operation.


Power & Sound:

The newcomer contains a slightly dated but still excellent chip, the ES9270, which, unlike the one mounted on the S3 Pro, produces 140 mW at 32 ohms. So this little dongle is definitely more powerful. I tested it on the 64ohm EPZ x Tipsy and they drive them at excellent levels and I don't feel any fatigue on the bass, which remains nice and full-bodied. I also tried it with the Hidizs MS5 to see if it could surprise me even with other level IEMs. I must say that on the iMac, I only need 3 volume levels and it is impossible for me to go beyond halfway. With the addition of the 75 ohm adapter, you can reach the maximum volume; it is better to stay around 64 ohm at most.



It supports the microphone; not many have this functionality, but I must say that it is convenient if you also use it for calls, conferences, and even gaming.





I think for the most part of this hobby, the power is sufficient but now there is also the Fiio KA11 on the market.

In terms of sound, I struggle to distinguish it from the S3 Pro. Hidizs always follows that tone that is not too neutral but slightly warm. On bright IEMs, it helps to better control the treble region while maintaining excellent details. I also feel slight coloration in the midranges but I must say it was a pleasant result.

Fast Comparison:

I don't think comparing it to models with balanced output makes much sense; obviously, they perform better. So the comparison will be made with other single ended DACs.

vs Hidizs S3 Pro



Very similar, so extremely similar that it is impossible for me to say that I noticed real differences in sound. I think there is slightly more emphasis on SD2 but it could be the extra power that gives it dynamics. We have less power and a much more elegant design but the rest is the same.

vs FiiO KA11



The increased power is instantly noticeable. The KA11 requires only two volume bars, whereas the Hidizs SD2 requires three. Both have a slightly warm sound, with Hidizs taking the lead. The Fiio produces a more controlled and decisive bass. The designs are completely different, but the most traditional is probably the most comfortable. I suggest you read the entire review.

Who do I recommend this DAC to?

At the time I'm writing this review, I don't yet know the market price, but I can tell you that to compete, it must be offered at an extremely aggressive price. The FiiO KA11 has positioned itself with a very low price; the power is excellent and it cuts out all the competition. However, the Hidizs SD2 has very broad compatibility on its side, including the USB A and Lightning adapter. You can use it on any device without buying additional adapters, and the sound is still very pleasant, even if it is not suitable for overly critical listening. Regarding the shape and angle of the jack, I'm not too convinced of the design. I see it as much more comfortable to connect to a laptop well placed on a desk than to use it on a smartphone that fits in your pocket.

Hi everyone! After having had the opportunity to get to know Simgot with the review of the EM6L, they also sent me their brand new DAC/Dongle, the Simgot DEW4X.


It is my first dongle with the Cirrus Logic CS43198 chip. I don’t know exactly if it should differ much from the more common CS43131 but I will try to convey to you as best I can the sensations I have had.

Though I’m still not as skilled as the most knowledgeable person you can find online, I’m starting to acquire an intriguing amount of Dac.

The review, as always, will be completely unbiased and uninfluenced.

I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.

My opinions are obviously subjective.

Tech Specs:​

• DAC Chip: Dual CS43198
• Decoding specifications: PCM: 384kHz/32 bit; DSD: Dop 128/Native 256
• Output power: 2x70mW on 3.5mm, 2x150mW on 4.4mm
• Distortion: 3.5mm SE 0.0005%@32ohm, 4.4mm BAL 0.0003%@32ohm
• SNR at 32 ohms: 3.5mm,125db / 4.4mm 130db
• Body material: Aluminum alloy sandblasting oxidation black
• Interchangeable Line Design: YES
• Cable material: high-quality OFC-wrapped shielding layer
• Connector: Type-c
• Output plug: 3.5mm, 4.4mm
• Body: 41.7*24.2*12.0mm
• Cable: 105mm
• Weight: 24g
• Price: 79.99 USD

Packaging:​

The box is decidedly simple: thin cardboard with a chrome effect. The package opens in a classic way; we find the Simgot DEW4X among some foam.


As accessories, we have:

• Excellent type C cable, covered in fabric
• Type C to USB adapter
• Manual

Given the price of the dongle, the packaging is absolutely perfect, the set of accessories is complete and the covered cable is nice and thick but still has good flexibility. I would say it is of excellent quality.

Build quality/First impressions:​

I confess that I thought it was bigger but in reality, it is one of the most compact dual chips. The construction is very solid and simple. The metal body has satin black paint; on the front we find the “X” logo, which vaguely resembles that of Twitter; and on the back we have some specifications and acronyms. As you will see from the photos, the design is very minimal, so minimal that even the volume buttons do not have + and – signs (many others have no signs at all). The feedback from the buttons is excellent, they are stable and seem resistant and durable.


The same goes for the LED inside, which does not have its own hole but can be seen by looking inside the outputs. I am not sure if it was a design decision, but they could have used the X on the front to light it up. Actually, looking more closely at the body, there is a small hole near type C! Honestly, you can see the LED light better by looking at the outputs.

Power:​

This is not the most powerful dongle; the market is raising the bar with each passing month. Fiio has dropped several bombs, including the Fiio KA11 and KA17, which have absurd powers. However, it’s not just a matter of brute power. I expected the Simgot DEW4X to produce a sound similar to that of a DAC equipped with CS43131. The shape indicates that the motherboard is not the standard PCB that is commonly used on multiple dongles. In terms of pricing, it is comparable to the Hidizs S9 Pro Plus, which is slightly more powerful.


Testing the SE 3.5mm with 140 mW at 32 ohm:

• Simgot EM6L, no kind of problem obviously so I added a 75 ohm impedance, which allows me to reach the maximum volume but the sound pressures are still high.
• Epz x Tipsy Star One with a 75 Ohm adapter, the sound pressure is still excellent. I would say that for most IEMs, they will have no problems.

Testing the BAL 4.4mm with 300 mW at 32 ohm:

• Hidizs MP145 requires a bit of extra amplification to express themselves at their best and I would say that you can’t complain here. Open soundstage and an excellent performance. Perhaps the DAC’s tendency to be slightly brighter pairs well with the set.
• Hifiman He400se After testing them with the Fosi Sk02 (full review coming soon), I admit that the difference can be felt. It’s not so much the question of the sound pressure reaching the same high levels, but I believe it is precisely the power reserve of the DAC that you connect to it that gives it dynamics, depth, and thickness. Let’s say that the DEW4X does well overall but if you have some full-size planars, you need to increase the power.

Sound Signature:​

I must say that despite it being the first dongle with this chip, I was positively surprised by the overall sound quality and as a chip, it is slightly superior to the more widespread CS43131, where, in my opinion, some details are lost. Obviously, I would like to remind you that to establish these things, you should put each dongle on a test bench and measure everything with precise instruments. My review is based on what my ears heard, with possible placebo effects included.


We don’t have digital filters but at least we can change the gain by pressing both buttons together at the same time. To understand which mode you are in, you have to look inside the outputs: if you see blue, you are on high gain; if it is green, you are on low gain.

Fast Comparison:​

vs iBasso DC04 Pro​

iBasso DC04pro has something more than the others; they may be small things but although the chip is identical to that of the Moondrop Dawn Pro, the OP-Amp department is evidently more refined. I don’t think the price difference is just a matter of brand but to be sure, they would need a teardown. It comes across as more musical and refined, with a soundstage that seems wider.

vs Hidizs S9 PRO PLUS​

Hidizs S9 Pro is a decidedly good model; like all the Hidizs I have tried, they are not very analytical but a little colorful to my ear. In price, it is equivalent to the Simgot DEW4X and personally, I prefer it. It has a sound that I would define as more “mature.”

vs Moondrop Dawn Pro​

First look Moondrop Dawn Pro
If you are on a limited budget, this is the best choice if you are interested in balanced output. Furthermore, it is slightly smaller than the DEW4X, even if the quality is slightly lower. Here we find the accompanying app where you can manage your dongle. Read the full review for more information.

Who do I recommend this DAC to?​

The Simgot DEW4X is an excellent dongle that is ultra-compact and has a decidedly more robust appearance than the competition. I am just sorry that some minor details were overlooked, such as the LED, which did not have a dedicated hole on the shell. Watching through the audio outputs is not a big deal, but it seems like a minor oversight. I’m sure a companion app would have been useful to many, but apart from a few important brands, there are usually no accompanying apps.


Personally, in terms of sound quality, I currently place it immediately after the iBasso DC04Pro, followed by the Hidizs S9 Pro. However, if I had a limited budget, I would definitely take a look at the Moondrop Dawn Pro or the Fiio KA11.

Disclaimer:​

Finally, the Fiio brand noticed me and I couldn’t be happier with this new collaboration. The Fiio KA11 was kindly sent to me for review purposes.


Though I’m still not as skilled as the most knowledgeable person you can find online, I’m starting to acquire an intriguing amount of Dac.


The review, as always, will be completely unbiased and uninfluenced.
I would like to remind you that I am just a person who enjoys trying out new items and listening to a lot of music; I am not an expert.
My opinions are obviously subjective.

Packaging:​

The Fiio KA11 box is presented in a very simple way; a more luxurious box would have unnecessarily raised the price. The opening of the box is sliding and we immediately find the KA11 nestled in the packaging inside a protective plastic bag.


By removing the packaging, you will find the manual and warranty policies. I would have thought of also finding a type C to USB adapter for connecting to a PC. Unfortunately, it is missing but for a few dollars, you can find it on AliExpress.

Build quality/First impressions:​

At first glance, it immediately seems to be of excellent construction and workmanship. The main body is made of some metal alloy to better dissipate heat (it heats up slightly), the design is simple, and a LED indicates the sampling being played.

Type C (midnight blue)
The cable is nice and thick and covered in fabric; I think it’s one of the most robust I’ve seen so far. The type C is slightly different in color from the DAC’s black; it is more of a midnight blue.

Power:​

We are faced with the most powerful entry-level dongle on the market. I don’t think there are other dongles so cheap that reach these powers. The Fiio KA11 is certainly revolutionary compared to all the dongles in the price range. Despite its only 3.5mm SE output, its 200 mW at 32 ohm is exceptional.


If I take, for example, the Jcally JM10, which has the same chip but isn’t as powerful, it has a cable that you can replace, the construction is good, but it costs more than the Fiio, which also has an app included. I’ll compare them later in the review.


You must take into account that the power varies if you connect the phone to the PC; probably the phone model also influences performance. It all depends on how much current the smartphone’s type C can output.


I therefore decided to compare the different power sources.


TEST on POCO M4 PRO with Tidal


In the test, I took IEMs and headphones that were a little more difficult to drive. IEMs like the Plutus Beast with 8 ohm impedance are a joke for this dongle.

• Epz x Tipsy Star One (64 OHM): The KA11 is not affected in the slightest. It seems to have connected to an IEM that is very easy to drive. Nice full-bodied bass. It is impossible to go beyond half the volume.

• KZ PR2 V2 (energy hungry): Hard to believe but going above 80% volume will cause immediate deafness (thanks to the fantastic treble of the PR2)

• Hifiman He400se (dongle eater): Here is the limit, at least on my smartphone. You can easily listen to them but you don’t reach scary levels.

TEST on iMac with Amazon Music

• Epz x Tipsy Star One (64 OHM): With a third of the volume available, you are already at the finish line.

• KZ PR2 V2 (energy hungry): Practically like the Star Ones on smartphones. Super easy. Unfortunately, the volume doesn’t go up much due to the very spicy treble.

• Hifiman He400se: You immediately notice the presence of a greater low range. It’s not just a question of volume but also of power reserve. They can drive them without effort but it reaches at least 80% of the volume.

He therefore demonstrates the ability to even drive full-size planars from a smartphone while maintaining excellent levels. However, I managed to obtain his maximum potential via computer.


This was my extreme final test: Star One 64 Ohm + 75 Ohm Jcally adapter




Obviously, I have tried several planar, hybrid, and single DD IEMs, and I must say that in most of them, this DAC is suitable. I didn’t notice any accentuated background noise, even on low impedances. This is not to say that the Hifiman He400Se reaches its maximum potential. Obviously, they are planar headphones, and the more power you give them, the more their dynamism increases. The test just understands the limitations of this dongle.

Sound Signature & Fiio App:​

The Cirrus Logic has recently lost a bit of warmth; in any case, it sounds less hot and slightly more refined. It is probably thanks to the amplification stage that uses SGmicro OP-Amps but I also believe in the improvements implemented by Fiio.


On the treble range, it remains very composed; in fact, some ESS is more suitable for trebleheads; the midrange is enriched with warmth; the voices are pleasant; and the bass remains the flagship of the Cirrus Logic.


Thanks to the proprietary app, you can change the filters but in any case, the KA11 is slightly warm and the mids are slightly recessed. Compared to an EPZ TP20, where the heat turned off the voices a little, this one is definitely better. Bass is always emphasized on cirrus chips or at least has a heavier or fuller impact.


DAC apps are always a bit approximate, but the necessary functions are there. We can choose between UAC 1.0 or 2.0 in case of compatibility or playback problems and between 5 digital filters. The volume control is absent, although it appears to be present on the product page. I must say that compared to the filters tested on the Hidizs S9 Pro Plus, I can feel the differences here, even if they are minimal. For a dongle of this price, it is definitely surprising.

Fast Comparison:​

vs Jcally Jm10 (old version)


One of my first DACs, the JM10, was a nightmare for me. Mine was part of a faulty batch that ran on almost nothing. I had to flash the Sonata BHD firmware and now it works. The volume has undergone a notable increase, as if it were always on high gain. It doesn’t excel at anything in terms of audio quality. Considering the higher purchase price, I would struggle to recommend it nowadays. Yet in terms of volume, my modified JM10 is impressive but loses out in detail compared to the KA11. The bass is also weaker.


The sound of the Ka11 is noticeably better for my ears since it manages to keep the sound open and very dynamic.

vs Hidizs S3 Pro​

The small Hidizs feature an ESS chip and the power is not very high. It is certainly not as versatile as the Fiio KA11, which has a more interesting output. However, if the connected headphones are not difficult to drive, I notice a certain emphasis in the vocal area, which makes the Hidizs DACs very musical.

vs F.Audio KS01​

I also added this model as it is extremely economical and feature-rich. It has very good power and a slightly brighter tone than the others. I don’t think the declared power is real. There is lots of firmware to try and key operation options. I would call it a DAC for nerds. The build quality and QC are not great.


Vs Moondrop Dawn Pro


Another excellent entry-level dongle; here we also have balanced output, the versatility is superior and we have a little more power. In terms of sound, they are quite similar; the Dawn Pro is slightly brighter (but that could just be my impression).

Who do I recommend this DAC to?​

In my opinion, this is the right dongle for anyone approaching this hobby. I say this because it costs exactly the same as a pair of DACs with an ALC5686, which, after a maximum of one month, could already be unsuitable for you. This guarantees you a few months of peace (with your wallet) and several hours of satisfactory listening both from your smartphone and PC (buy a small adapter if you don’t have Type C). It is not a dongle for analytical listening, as there are more neutral ones but for beginners, these problems do not exist (in reality, I don’t have any problems either, as I simply love listening to music).

In terms of durability, I don’t think you will have any particular problems. The construction is very solid and the cable is quite robust. On the site, they also declare that various resistance tests have been carried out.

I conclude by saying that this DAC will certainly sell a lot. I would not recommend it if you need to drive a He400se or full-size planars because there are more suitable dongles (obviously not at the same price).

If instead you need a more versatile dongle for a few dollars more, you can find the Moondrop Dawn Pro. In terms of sound, the latter seems slightly brighter, but it is a very minimal difference.

I thank Fiio for this opportunity. The only real lack of the Fiio KA11 is the lack of the USB adapter; for the moment, it is an unrivaled entry level.
