Packaging is well done, it's a large enough well decorated box to let you know something inside is good. Inside is the very beautiful MD Stellaris, a nice cable similar to the LAN or at least in look. The case is the KATO case, and it fits them well. The Tips are non-standard for MoonDrop, kind of a longer SednaEarfit Crystal in materials but there is also Foam ones in different sizes. The shell is oblong and has that Starfield paint and design look. So, these take many cues from other well liked MoonDrop IEM. Build is very solid with some heft. Once in you won't notice it much. The Nozzles are big and extend deep into the ear, because of this isolation is superb.



Sound:
Bass:
The Lower end on the MoonDrop Stellaris is more of a quality over quantity kind of Bass. There is a good detail and Mid-Bass still has kick when called on, and Sub-Bass shows good depth at times but nothing too deep, this is insertion and tip dependent. Bass has good speed and details overall.

Midrange:
The Mids are clearly a strong point of the Stellaris. The mids present with good energy, they are both open and well textured. Somewhat just shy of transparent and Neutral with separation, and front and center vocals, both male and female are equal in body, quality and details.

Treble:
The Highs are energetic and bright with good details. For certain music and warm sources, they sound very natural and open. The treble has excellent speed and is revealing to a fault with somewhat good microdetails, and while I found the highs pleasant enough on most recording it can be unforgiving on brighter ones. Treble is spiky at some points and combined with upper treble can be harsh at times. Easily fixed with the included foam tips, or use of hybrid ones, and of course EQ. Honestly, I don't like to do ever.

Soundstage:
Its open and has a wide field with good depth and high too, above average in this. The Stellaris also has a fair amount of separation. Imaging is very accurate, and it could do some gaming but it's not holographic, 3D or any other catchphrase.

Afterthoughts:
The MoonDrop Stellaris is a unique tuned IEM planar IEM, not for everyone. It has many good traits, and it should be noted this needs power! I used the ifi Gryphon for the majority of the review with the Questyle M15 and Periodic Neon at times. Its not small either but for me after the right tips it was all just a pleasant experience.

What's in the Box:
- Foam tips
- 3.5 to 6.3mm Adapter
- Shirt Clip
- 3-Flange tips
- Filter replacements, and the tools necessary to perform the replacement.
- ER4-XR units
- Detachable cables
- Storage hard carrying case

The Eytmotic ER4XR comes in respectable packaging inside is all above accessories. They certainly give you a good amount of what you'll need. I found the ER4XR weird at first, I have similar shaped IEM and some triple flanged tips but these fit deep. It will take time getting used to them. afterwards you won't notice they are even there and going back to other IEM the seal and isolation will not be as impressive. The units are made well, and there are tips for every ear. I like the cable and the fact they went with MMCX. There are filters included but they should be changed as directed so it will be an additional expense.

Sound Impressions:
Well start by saying this version has an extended Bass response with a single full range BA driver.

Bass:
There is surprisingly not very much Sub-Bass here. Mid-Bass defiantly is the more and most prominent with good upper Bass details. The Sub-Bass can be heard with enough details but lacks a deep impact. Mid-Bass is super-fast and can handle boosted songs without falling apart to a distorted mess. The Bass in general is detailed and lends to a warm, smooth lower end.

Midrange:
Mids are clear with a warm and sometimes thick register to male vocals, this is in contradiction to the female artist that sound more in your face but not in a harsh way usually. At adequate volumes and lower ones Mids are balanced and well heard with no recession. Source and recording will be intricate in weather the upper mids are presented. Clarity and details are defiantly a feature of the ER4XR and SR Mids.

Treble:
The Highs of the Eytmotic are relaxed and definitely good for treble sensitive listeners but maybe to an extreme.
The highs lack air and energy in general and give the upper end a softness, don't get me wrong there is clarity here fine details and extension are more subdued. Most songs sounded like the symbols were just a gentle presence.

Soundstage:
The Staging on the ER4XR is is small, not narrow but more like a small room very closed in. Imaging, details, as well as the great positioning and fine separation are great features.

My Afterthoughts:
The Eytmotic ER4xr is unique in its tuning, design and sound. It's a high quality In Ear with excellent details and clarity. I can see why they have a large following.

Packaging is medium in size and inside is a everything I could need for an IEM. I found the shells to be well made and all metal build, they are on the smaller side so fit should not be a problem. I found the comfort and isolation to be very good.

Sound Impressions:
Bass:
The S12 Pro presents with a with a speedy and detailed attack, it sounds almost dynamic, impact is well defined but not very powerful, both the Sub and Mid-Bass have decent weight, and texture, although Mid is more prominent. The Bass in general has an almost neutral feeling at times to the overall bass performance but there is no mistake Bass has a good punch albeit with a rapid decay.

Mids:
Midrange is very clear and forward centered. Vocals have decent body, but male vocals have more weight to them.
The Mids themselves are very well defined and mildly there is a hint of warmth, with a fine texture and pleasant details. I found them not shouty and no harshness.

Treble:
The highs are crisp and detailed without over extending. They have a nice amount of openness and balance.
No harshness up here and just a perfect example of good tuning. Treble sensitive should be able to tolerate this well.

Soundstage:
Stage is wide open, and you can pinpoint things easily even on busy songs, it has good depth and height as well. The separation of each instrument is clearly noticeable. The technicalities in general are much better than most in this price range.

Afterthoughts:
The Lestshuoer S12 Pro is an instant classic and favorite. An enjoyable and very competent IEM most people should try for sure. It is well made and comfortable with excellent accessories.

SPECIFICATION:

MODEL: HIDIZS MP145
IMPEDANCE: 30Ω
SENSITIVITY: 104dB
FREQUENCY RESPONSE: 20Hz - 40KHz
CABLE LENGTH: 1.2M
PIN TYPE: 2-PIN CONNECTOR (0.78MM)
PLUG TYPE: 3.5mm, 4.4mm
DRIVER UNIT(S): (1) PLANAR MAGNETIC DRIVER


The package is medium in size and made of plastic as most Hidizs boxes are. It is adorned with gold lettering and much documentation. Inside one finds these items.
Package and contents:
The two Hidizs MP145 capsules.
3 pairs of tuning filters.
One storage bag.
3 pairs of SxMxL size tips for vocal tuning.
3 pairs of tips size SxMxL for balanced tuning.
3 pairs of tip sizes SxMxL for bass tuning.
1 user manual.
1 warranty card.

The MP145 shells are solid and well built, they are however on the larger size, so small ears should take note. I found comfort for me above average, and isolation was very good. The accessories were well made, but I really would have liked a case for such a nice-looking IEM. It should be noted that these like a little more power than an average BA or DD IEM. I would recommend a decent dongle-DAC at the minimum.

Personal assessment and opinion: The MP145 is large and made entirely of metal. For me the shape and roundness of the back are comfortable, I love the cable but wish it was modular. Besides the pouch for storage, the unboxing was good, and everything points that this is a premium product.

Equpment used:
ifi Gryphon, ifi UNO, Dethonray SG1, Questyle M15, Fosi audio DS2, Hidizs XO, Burson Funk, Periodic Neon, TempoTec V6, Surfans F35, ifi GoPod, and TRI TK-2

Sound Impressions:
The Hidizs MP145 has a unique big Planar sound.

Bass:
The Bass on the MP145 is very well rounded and balanced sounding. There is good speed with both lower and upper Bass and excellent texture. While the Bass does have a fast decay it still manages to be fun without too much overstepping into the Mids.

Mids:
The Midrange is rich and has good note weight, both male and female sound lively and full bodied but not overly thick, the MP145 does have a little recession to the lower mids but it is overshadowed by the wonderful vocal details and transparency.

Treble:
The Highs present with a good energy, they are open and airy with just the right amount of sparkle. While lower treble and upper mids have a slight heat to them this is not always present and not an issue with normal volume and decent recordings. I found the highs to be well extended with control and details.

Soundstage:
The MP145 Has a magnificently wide stage, it does have good depth and height as well. The overall performance has precise location and layering with me being able to hear each separate instrument clearly. The soundstage doesn't suffer any penalties from busy or boosted lower end songs.

Afterthoughts:
The Hidizs MP145 is one of those IEM like the S12 destined to be on everyone's list. It has the right combination of an accurate and detailed but never boring sound. The design is cool, and it is made extremely well.

Product Information
Model：FEDAI DX2
Drive unit：11mm moving coil unit.
Impedance：16Ω
Sensitivity：98db
Interface type ：3.5mm/Type-C gold-plated plug

The Fedai DX2 comes in a familiar case much like most ultra budget IEM it is small but this one is well decorated.
Inside you get three sizes of generic Starline tips, a cable similar to the old CCA ones and the units that look familiar too. Build is decent and isolation was average. I did find them comfortable and light. It is easy to drive despite low sensitivity.

Sound:
Bass:
The Sub-Bass is powerful, but the Mid-Bass is more in front and has more boom to the mix. Bass is well textured and warm.
Mids:
Midrange is Warm and thick bodied, with some recession and smooth details, vocals sound pleasant and are positioned slightly forward with a good smoothness.
Treble:
The highs have energy and sparkle, but details are smooth and relaxed.

Stage: is above in width and average in technicalities having a decent separation and accurate imaging but is far from a technical monster.

The Fedai DX2 is a super inexpensive IEM with a detachable cable and a fun V-shaped signature. It reminds me much of my old KZ ZST pro but with better control in both lower and upper frequencies.

Large and wide extension with a smooth top end and commanding bass is what to expect from MACH 70s impressive soundstage: a listening experience perfect for all people and music genres.
The MACH 70 features a proprietary seven-driver system with single low, dual mids, and quad highs and a 3-way passive crossover.

TECH SPECS

3-way Passive Crossover
DRIVERS: Seven Balanced-Armature Drivers
FREQ RESPONSE: 5Hz – 22kHz
SENSITIVITY: 110dB @1kHz
IMPEDANCE: 42 Ohms @1kHz

The Westone Mach 70 comes in a well decorated box with ample information, inside is the hard case, in the case is a large assortment of accessories, a carabiner, the Mach70 unit, Estron ULTRABaX stock cable, a large number of tips both silicone and foam, a velveted pouch, tool for cleaning, cable organizer, and warranty card with a sticker. The Mach70 itself is made of a high impact plastic with a gray and black matt finish. light and durable, I found them comfortable. Isolation is very good; this product is for performers, so it has to be. The huge case is a great touch. everything is well made; however, while the Estron ULTRABaX cable is one of the thinnest upgrade cables with 224 strands and a quad-twisted design. It also has an ultra-low impedance rating of 0.6Ω, this is so it won’t color the output and it is well made but it also doesn't offer a balanced connection. The foam in the case can be customized to fit your needs.
The Mach70 is very lightweight even with the included cable. It provides excellent isolation and comfort.

The sound impression:
Bass:
The Bass is tip dependent but with the right fit you'll find it is much different from the Mach 60 and 80.
Sub-Bass is deep and powerful but yet doesn't stand in front of the other frequencies. There is a nice lower rumble with good details and control. The Mid-Bass is more prominent with an impressive slam and good speed. Despite there being only a single BA driver for the lows it is fun and dynamic sounding. The bass in general is well controlled and doesn't fall apart on heavy boosted recordings like some BA configurations.

Mids:
The Mids present with a nice thick lush tone. The Mids do not suffer recession despite the Bass and vocals are forward center, vocals have good body and male vocals really sound impressive.
There is great separation throughout and the Mids here are warm with excellent emotion. The details are a little more smoothed than the more reference oriented M60.

Treble:
The Treble presents open and airy with good energy and smooth details. Its more energetic to match the Bass prowess of this unit. The highs are well balanced in the mix and sparkle but roll off quick and naturally. Treble sensitive will enjoy this, as it is never harsh or fatiguing.

Soundstage:
The stage is naturally open and well placed. It handles the busiest of recordings with ease. There is no penalty from the Bass or heavy boosted music. It has accurate details and is organic in its shape.


Conclusion:
The Westone Mach70 Is well made and more than suitable for a fun sounding monitor but also has that engaging midrange, smooth pleasant Highs, and enjoyably fun Bass too. The M70 is made well and comfortable for all day use.

Technical Specs:
3-way Passive Crossover
DRIVERS: Six Balanced-Armature Drivers
FREQ RESPONSE: 8Hz – 20kHz

The Westone Mach 60 comes in a well decorated box with ample information, inside is the hard case, in the case is a great assortment of accessories, a carabiner, the Mach60 unit, SuperBaX stock cable, a large number of tips both silicone and foam, a velveted pouch, tool for cleaning, cable organizer, and warranty card with a sticker. The Mach60 itself is made of a high impact plastic. light and durable, I found them comfortable. Isolation is very good; this product is for performers, so it has to be. The case is a great touch. everything is well made; however, while the LINUM ESTRON SuperBaX cable "with a resistance rating as low as 0.75Ωs" is made of high-quality materials and performs well, it is rather thin and springy, it also doesn't offer a balanced connection. The foam in the case can be customized to your needs.

The sound impression:
Bass:
The low end presents with good energy and depth, while not overpowering it has medium speed, precise decay, and details. There is less of a boost compared to the MACH70 and more of a neutralish tone. Maybe due to one more Bass focused driver in the M60. The bass works well for speed metal and EDM music.

Mids: The Midrange presents itself balanced not over emphasizing instruments or vocals. Both are forward and evenly placed. Mids are lush and have good body but are medium in thickness in most recordings but can sound thinner at times. They do have great details allowing you to hear each instrument separately quite well.

Treble:
Highs are detailed and have good air to them but are overall smooth and natural. The energy is kept in control with a ample amount of separation and decent speed. I found them to be not harsh even under poor recordings. The tuning is more suited to monitoring or critical listening.

Soundstage:
The stage is shaped with a decent width and less depth it has a smaller room, perhaps a club or garage band like openness. It does have a well-done imaging and accurate overall presentation.

Conclusion:
The Westone Mach60 is part of the Reference line and is more geared towards professional use or the decerning critical listener. It has a nice lightweight feel and is a natural sounding IEM with a good neutral and detailed signature.

The MS1 Galaxy is a more budget friendly offering from the company. It comes in a responsible package with Small to Large tips, a cable that is decent quality and the MS1.
The MS1 one is built like a typical IEM in its price range, very light weight and plastic build. It is comfortable and provides adequate isolation.

Sound:
The MS1 Galaxy presents with a warm V-shaped signature.
The Bass is highlighted and forward. The Sub-Bass is king here giving a commanding boom to the mix. Mid-Bass is behind with a nice slam but is overshadowed by the SUB. Mids are as expected. Warm and thick bodied, with some recession and smooth details, vocals sound pleasant and are positioned slightly back. The Treble has enough energy to be noticed stringed instruments sound natural. Stage is average having a decent separation and accurate imaging but is far from a technical monster.

Conclusion: The Hidizs MS1 is an enjoyable budget IEM, it is targeted towards POP, Hip-Hop and Electronic music. The Bass is too overwhelming for Metal but Classic Rock sounds fine. It's a fun and warm IEM nothing too serious for gaming or critical listening.

Sound:
Bass: The new composite driver Delivers a faster performance, and the Mid-Bass is Punchy and neutral focusing more on precision than low end rumble, still it has a great detailed Bass that is non fatiguing and well controlled.

Mids: are rich with details somewhat neutral and bright on top but there is that slight warmth down in the lower mids. They also present some really clear vocals with decent body and vocals shine without being shouty or harsh. Male and Female vocals sound good and instruments have a good amount of separation and clarity throughout.

Treble: The highs here have some sparkle and decent details. The performance is much improved here but they are still a little laid back, not that it is a bad thing as they never got to a harsh point but some details are lost to me due to their laid back nature. Still they are easy on the ears of treble sensitive people and present a nice balanced non peaky Treble.

Soundstage:
Is above average with very good imaging and nice separation overall, it feels natural and open. It could be good for mobile gaming.

Conclusion: The Janus3 is the continued evolution of the product line in a good direction.

The Neon comes with some very good specification and a Qualcomm QCC3034 inside, there is also a professional grade 6mm diameter condenser microphone. To use for calls or video. Neon has four dedicated buttons: volume up, volume down, the classic “triple button”, and a source button. Each button has a unique shape for ease of identification. A single LED intuitively shows current status of Neon. Neon also has our legendary AO² Auto-On/Auto-Off power control.

Sound:
The Neon has a nice balanced signature with very good clarity and dynamics. I found it to be a little north of neutral with just a hint of warmth.
Bass, Mids, and Treble present with good details and volume is more robust.

I had no connection issues and it performed better than expected considering the size and cost I think it's a great addition to my travel equipment.

It is sufficient enough to please most Bass loving audiophiles.

Mids: Present rich and thick with warmth and body. It has a slight rescission because of the typical V-shaped signature. Still Mids are full of character and smoothness. I found male vocals to be very pleasant.

Inside is the EW200, a cable, three sizes of tips, and a felt pouch. All of the items are decent quality, The EW200 are made well a nice solid metal build with shiny polished outside casing. The shape is comfortable, and the isolation was very good.

Sound:
Bass:
The EW200 present with a tight and speedy Mid-Bass punch, The Sub-Bass is thee in the background and has details and presence but is Neutral and Mid-Bass is more prominent. It is definitely a quality more than quantity Bass.

Mids:
Mids are highly detailed and while it handles both well female vocals sound a little more emphasized. Mids have good clarity with separation and an accurate portrayal of note weight.
Treble:
The treble is surprisingly energetic but still has a control on how much is put out. There are good details here and it's even more amazing that this is just a single DD. Highs present crisp, open and well-extended.

Soundstage:
The staging is small but even being equally wide as its depth, still it makes, and accurate portrayal of space and imaging is good.

Conclusion:
The SIMGOT Maze EW200 is a well-tuned neutral IEM with good technicalities, its comfortable well-made and is very pleasant at normal volumes.

The package is simple, accessories include a cable and tips as well as the unit, they are typical CCA quality as I've come to expect. Nothing too fancy just made well. The pianist shells are resin and metal with cool angled venting. The look reminds me of other KZ IEM, they provided decent isolation and good comfort for me.

Sound:
The lows present deep with a fast decay and a well-controlled punch. they have a natural warm tone with good texture and details.
The Mids are warm and present with forward vocals, notes have good weight, particularly on stringed and percussion instruments. Upper Mids are brighter and a little more forward. There is a small amount of elevation in the upper mids and lower treble.
The Treble is extended well with energy and sparkle. It sounds excellent but it's not the most natural highs and might not be for treble sensitive.

Soundstage: Staging is accurate with good overall positioning it is average in width and perhaps a little deeper.

Afterthoughts:
The CCA Pianist is a new, interesting Hybrid. It has a theme and backstory I found interesting. The triple driver produces a good overall performance. I found it shined best with acoustical and jazz music and similar. Driving it directly off my phone it seemed more bass heavy and typical V-shaped, it opened up more with a simple dongle DAC.

Build quality was very good, I think on par with the second- Gen but I really liked the look of the original to be honest. The packaging is decent, to be candid I always thought the Kato unboxing was superior.
The case is more than adequate in size, the cable is good but not on par with other brands in this price range like Kinera. Tips are weird and it does take much time to find a second party tip that will not ruin the beautiful sound of the B3. I ended up with spinfit and symbio, the later didn't perform to my liking on this IEM. I found them large, so you'll not want to sleep with these on, but they were comfortable on me for a few hours at least.

Sound:
Bass:
The Bass is very good on this one and scales depending on source and music. It has the ability to dig down deep when listening to rap and K-pop and stay composed during acoustical. Both Mid and Sub are adaptive, have a good speed and neutrality. Bass in general is an improvement over the B2 but still can present a little thin.

Mids:
Are excellent and present more balanced than neutral, they have a decent weight and timbre. vocals are placed perfectly and sound so natural and rich. This does both female and male quite good.

Treble:
The highs present with a smooth almost neutral sound, medium energy level, and fine sense of openness. There are fine details but no harshness ever.
Soundstage:
The stage is vast but not artificial. It lends itself well to live performances. openness, accurate and wonderful separation. can handle busy recording with ease.

Conclusion:
The Blessing3 is a continuation of the B2 and also an improvement Bass wise. I think in general it is better tuned with some small improvements overall. It looks amazing and should be considered for fans of the B2.

User Manual

The Cleer II sport is a improved version of the original with a bunch of upgrades and smart features.
The ARC2 sport is lightyears ahead in terms of bass quality and impact, while far from a bassheads dream there is a notable Sub-bass and Mid-bass kick while being balanced and clean. Mids are still very clear and only a hint of warmth is present with most music. Treble has air and sparkle but falls of quickly. The stage is that same wide open and massive real-world natural goodness of the original.
Hand gestures, better chipsets, a replaceable cable, and much better call quality round of the improvements.

The Cleer Scene is built very well with a solid feel to it and looks premium as well it has a wide shaped body cylindrical with a sloped front and looks sexy in the red. Setup was easy and quick.

Calls sounded clear and this is a useful feature I like. The device can also work wired if the source has no Bluetooth but a 3.5mm output jack.
Buttons are located in easy to reach places on top and the BT and power on back.

Sound: The Scene has dual 48mm Drivers two base ports on each side and sound radiates from the front cloth grill.

I found the Bass to be punchy and tight with a speedy SubBass response, Mids are clear with great vocals and highs are sparkly with good overall details and a balanced yet fun signature. The sound fills the room and like the STAGE the SCENE can get nice and loud without distortion.

The XO's Box is little and inside is the XO, documentation, a Type-C to C cable ,and a USB C to USB-A cable.
The Hidizs XO is silent producing no ground noise even on all BA IEM and low Ohm IEM, it has a transparent and Neutral with a little warmth to give it character. It still manages to be very detailed and can has good technicalities.



Conclusion:
This is a cool looking kind of niche dongle, offering a nice crisp, and detailed, Neutral sound. The lights are unnecessary but satisfying! Its not the most resolving or the most powerful but it looks good and is a vast improvement over the stock chipset in terms of quality and volume.

The AZ20 is the latest earhook adapter from KZ, it is designed with their products in mind but there are other companies that use QDC 0.78 two pin connectors, and they work fine too. It comes with impressive internals and support for Bluetooth 5.3 and aptX Adaptive and LL, there is no LDAC but they sound great regardless.
The AZ20 is made well and comfortable for listing for hours, honestly you won't know it's there.
The sound modes are useful but in balanced mode the have a nice rich textured bass and a wide stereo sound with good details. I did have a lot of cut out issues out walking but indoors they worked perfectly.

In a nutshell:
This is a convenient way to listen to my KZ camp IEM, and it's really easy and carefree to use. I like this kind of product more than I thought I would but for walking around or hiking the area unreliable.

The ifi GoPod is a Bluetooth ear hook adapter that lets you turn your IEM into a great sounding TWS earphone.
The device comes with a large 1500mAh battery case and two different connecting hooks a MMCX and a Two pin 0.78mm, there is also others available to purchase. It has touch controls and placing the connect IEM in the case will activate the IE match feature. Call quality is excellent thanks to its Qualcomm chipset. Comfort is okay, I think the hooks themselves are a little stiff and small for larger ears. otherwise, I would have given it a 5*

Sound:
The quality is large with a nice open and detailed presentation. It is for the most part neutral and transparent.
It has excellent dynamics, and it is linear. There is little difference using a all BA or a Single Dynamic in terms of ground noise, it's very silent with no hiss or static. I ran a large variety of IEM both hard to drive and very sensitive, from Planar to multiple configurations, BA, DD, Estat, Planar and Hybrid. The GoPod handled them all perfectly.

Conclusion.
The ifi GoPod is a super convenient way to enjoy my collection, with LDAC and enough power I don't see any big limitations with this product.
