IEM/Earbud/Setup configuration: Stock large silicone eartips,, any form of EQ or MSEB off, 40-60% volume.

(Additional note here: I’ll evaluate the ZS10 Pro 2 first in its stock configuration where the switches are all switched on (UUUU). I’ll explain and compare it to other IEMs right after.)

=================================================================================================================
Sound signature:

• Just like its previous ZS10 siblings, the ZS10 Pro 2 kept its faith to their usual mild-v sound signature, which leans to the brighter sound signature. What makes this different from its siblings is the absence of bloat from their previous variations, making the overall sound more mature and nearly clinical. This also affected the technical performance in a very positive way.

Lows:

• The lows are mildly elevated , but lack the bloat that are found in the previous ZS10 generations, in general. It is still midbass dominant and leans to the faster side of the spectrum in terms of attack and decay. Subbass is still present, does its job, shows where and when it is needed, but never becomes too “ear-shaking” or overly chunky, which may dissatisfy bassheads. However, the bass on this set will be more than enough for most people and their playlist in terms of quality and quantity for its respective retail price.

Mids:

• The mids are still mildly recessed, but are much more cleaner and vivid when compared to the ZS10 Pro. Midbass bleed or bloat is nowhere to be heard in this set, or non-perceivable to my ears, at least. This also means that the lower mids trimmed a bit of weight and depth. Upper mids are still elevated, clear, and have a decent amount of air. As for the mild peaks and harshness, it is still apparent in this region, which made me not recommend this IEM for those people who are very sensitive to bright upper frequencies.

Highs:

• As for the highs, it is definitely bright and elevated on this set. The ZS10 Pro 2 avoided unusual sibilance and harshness in this region, But I will still not recommend this IEM for those people who are very sensitive to upper frequencies and BA timbre. The treble extension is decent and airy. Detail retrieval is average at best.

Soundstage, Imaging, and separation:

• This region is the most noticeable improvement that the KZ ZS10 Pro 2 has. It is more technically capable when compared to its previous siblings. The soundstage is wide with a good amount of depth and height. Separation and layering are above average for its price and handles very busy tracks. Imaging is accurate and renders vocal and instrument positions quite well.

=================================================================================================================
Other Switch Configurations!

DDDD config

• This configuration is also mild-v in terms of sound signature, both ends of the spectrum are less elevated compared to the UUUU config. Technicalities also took a hit on this configuration and sound more “flat” to my liking, particularly on the soundstage.

UUDD config

• This configuration elevates the lows and tones down the upper frequencies, making things sound more thick and warm. This however hits the soundstage as well, in terms of width and height.

DDUU config

• This configuration elevates the upper frequencies, giving its sounds a sense of air and very good resolution. Technical performance is also affected positively in this configuration, at the expense of more frequent peaks and mild sibilance.

=================================================================================================================
Other IEM Comparisons!

VS 7Hz Salnotes Zero 2

• The Zero 2 is a warmer, more balanced sounding set. Mids are near neutral on the Zero 2. Its treble however lacks extension and air to my ears. Technical performance is better on the ZS10 Pro 2, particularly in its separation and layering.

VS Simgot EW200

• The Simgot EW200 is a more neutral sounding set compared to the ZS10 Pro 2. Bass is near neutral on the EW200. Mids are also more open on the EW200, and both sets exhibit unperceivable bloat nor bleed. Treble is more airy and extended on the EW200. Technical performance is better on the EW200, but not by much when compared.

VS Etymotic ER3SE

• Both exhibit some BA timbre, but the ER3SE has less of that when compared. The ER3SE is also dead flat to my ears and does its best to render the actual sound of the track and source paired with it.

=================================================================================================================
Pros:

• A refined, cleaner-sounding KZ Classic!
• All rounder, mild V-shaped sound signature (subjective)
• Clean, non-lacking, mildly elevated lows.
• Clean, open mids.
• Extended, airy treble.
• Above-average technical performance under 40 USD!
• Versatile tuning switches!
• Very good build quality.
• Very good fit, comfort, and isolation.
• Easy to drive.

Cons:

• BA timbre is apparent in most tracks in my library.
• Instances of peaks and mild sibilance are present in certain tracks.
• IEM can be bulky for smaller ears.
• Barebone accessories, they even forgot to put a medium sized silicone eartips in my unit (could be an isolated case, but a good heads up)
• While a very good improvement over the ZS10 Pro X, ZS10 Pro, and the original ZS10, this IEM does not sound dramatically different when compared to other KZs that have recently existed.

=================================================================================================================

KZ is on a roll on “refreshing” their popular sets that have existed before, to keep up to the Chi-Fi’s saturated market and balls-to-the-wall standards. The ZS10 Pro 2 exhibited those standards well for its asking price, in terms of overall technical performance. Looking at a bigger picture however, it struggles to stand out among its competitors for its asking price. Don’t get me wrong, the ZS10 Pro 2 never sounded bad to my standards and preferences, but this won’t definitely be the first IEM that I will recommend for its asking price, due to the fact that its own sibling from the same company, the CCA Trio, is better for less money.

Pairing recommendation/s:

• Source: This works well with neutral sources you pair it with, but this will suit better with warm sounding dongles, such as the Simgot DEW4X as an example.
• Eartips: The included eartips hinder the sound of this IEM, so I suggest using a better eartips such as KBEAR 07s, Tri Clarions, Final Es, or Tangzu Tang Sancais.
• Cable: The cable also hinders the fit a bit to my ears due to its preformed earhooks. NiceHCK cables work well with this set in terms of comfort.

IEM/Earbud/Setup configuration: Stock medium eartips, any form of EQ or MSEB off, 40-60% volume.

Additional Note here: I’ll be reviewing the EA500 LM in its stock, pre-installed gold tuning nozzles first then comparing it to the other nozzles later on.

=================================================================================================================
Sound signature:

• The Simgot EA500 LM follows the Simgot’s house sound which leans to the brighter side of the spectrum. This means that the EA500 LM is a mild-u (near neutral) sounding IEM that leans to the brighter side of the spectrum. What makes this different from its older siblings is that there is a noticeable improvement in technical performance when compared, albeit not being night-and-day.

Lows:

• The bass on this set is mildly elevated, fast, detailed, and non-lacking for most people. Midbass is definitely more dominant here compared to its subbass, exhibiting a punchy, snappy attack and decay. This doesn’t mean however, that this lacks the subbass when the tracks call for it. It still delivers sub bass with a decent amount of depth. While this may not be a basshead’s dream, I am still happy and pumped that they managed to improve the EA500 LM’s overall bass character. It is now more detailed and textured, while keeping its clean, fast characteristics found on its older siblings.

Mids:

• Simgot’s take on the presentation of their mids is always preferred by my ears because of its openness and details, but is not favored by some due to its “thin” in presentation. The EA500 LM exhibits its sound a bit thicker but not far compared to its older siblings. Lower mids are clean and free from midbass bleed, but are mildly recessed. Lower vocals and instruments are detailed in this region, but will sound “thin” for those ears who are accustomed to a warm, smooth, lush character in terms of presentation. Upper mids are elevated, exhibiting a very good amount of clarity, air, and sparkle. The EA500 LM with its gold nozzle does not exhibit any unnatural peaks and harshness, but is still bright and is not recommended for those people with sensitive ears as it can be “too much” for those ears. In a nutshell, Simgot again traded the warm, “safe” character for a vivid, open, airy presentation, which really fits my preferences, but I am also aware that this will not fit some ears, so do take a note of that.

Highs:

• Moving on to this region, the treble in this set definitely leans to the brighter side, exhibiting a very good amount of air and sparkle. Peaks and harshness are still not heard with this good nozzle, which is a good sign for most ears. Detail retrieval is excellent and will definitely render all the details in the track.

Soundstage, Imaging, and separation:

• Here’s where the EA500 LM differs itself from its previous siblings. The soundstage is wide, tall, and holographic. To my ears this is above EM6L and midway to EA1000 in this context, but definitely not on par or above it. Separation and layering is excellent for its price, and will render heavy passages clearly with ease. Imaging is precise and renders vocal and instrument positioning clearly. I did use this when I tested the latest Call of Duty Warzone Mobile game and it is more than enough and precise on that game as well.

=================================================================================================================
Other Nozzles Comparison!

VS Silver Nozzle, Red Ring

• The EA500 LM sounds nearer to the Harman Target with this nozzle. Its bass is more elevated and thick, mids exhibited a smoother warm character, and the treble remained the same. The soundstage however, took a toll on this nozzle to my ears.

VS Silver Nozzle, Black Ring

• This nozzle made the EA500 LM brighter compared to the gold nozzle, elevating the mids a bit compared to the gold nozzle. This also means that the bass became more tight and lost a bit of detail and versatility. Vocals became elevated and sound mildly “nasal” to my liking. This nozzle also introduced peaks and sibilance which is almost non-existent with the gold ring paired. It also affected the layering and soundstage, in terms of width and depth.

=================================================================================================================
Other IEM Comparisons!

VS Simgot EW200

• The EW200 is brighter than the EA500 LM and “thinner” if you find the EA500 and EW200 thin to your preference. Bass is also lesser in quantity on the EW200 and is less detailed when compared. Soundstage is also “flatter” but wider, if that makes sense.

VS Simgot EA500 (Black ringed nozzle)

• The EA500 is brighter and is closer to neutral when compared. It is also prone to sibilance and harshness when compared. Soundstage is more immersive on the EA500 LM. Separation, layering, and imaging are also cleaner and precise on the EA500 LM.

VS Simgot EM6L

• The EM6L is EA500 LM’s thicker-sounding, warmer, “safe” brother. The EM6L is safer in upper frequencies, but the EA500 LM is airier and much more extended. The EA500 LM has better technicalities as well, but not big in terms of difference.

VS Celest Phoenixcall

• The Phoenixcall has more bass quantity and has more recessed mids when compared to the EA500 LM, but is lesser in treble quantity when compared. This also means that the Celest Phoenixcall has less air on the top-end. Technical performance is also cleaner and more precise on the EA500 LM

VS Celest Pandamon

• The Pandamon is a more balanced set when compared. It is thicker as well and exhibits a tinge of warmth. The EA500 LM is airier. Technical performance is also better on EA500 LM due to its soundstage.

VS Letshuoer DZ4

• The DZ4 leans to a more laid-back, neutral, vocal-centric sound when compared. It is also less detailed when compared to the EA500 LM. Technical performance is better on the EA500 LM.

=================================================================================================================
Pros:

• The “perfected” version of the EA500 and EW200!
• All-rounder, near-neutral sound signature.
• Very good technical performance improvement!
• Well-balanced tonal and technical performance in Simgot fashion!
• Fast, non-lacking, detailed bass response!
• Clear, open, near-transparent mids!
• Airy, well-extended sound signature.
• Excellent detail retrieval!
• Holographic, precise, well-layered technical performance!
• Additional tuning nozzles!
• Very good fit, comfort and isolation.
• Very good build quality!
• Excellent among and quality of accessories!
• Easy to drive.

Cons:

• Just like its older siblings, its finish is prone to scratch and smudges.
• While arguably a very good improvement fromEW200 and EA500, its overall improvement isn’t a huge leap when compared.
• While this set is less bright in sound when compared to the EW200 and EA500, this set can still be shouty or “too much” to sensitive ears.
• A cleaning cloth would’ve been a nice treat due to its smudge and scratch prone finish. An additional set or eartips would be a good treat as well.

=================================================================================================================

As I listened to the EA500 LM, I decided that Simgot took the input they received from earlier sets and applied it to this set. This is their "nearly perfect" IEM for around $100 USD, in my honest opinion. In practice, the EA500 LM's upgrades aren't so "big" when compared to their earlier sets, because, in my perspective, they already made very good IEMs in their respective price ranges, such as the EW200, EA500, EM6L, and many more. But that doesn't affect the fact that I recommend the Simgot EA500 LM to anyone looking for a highly-resolving, technical IEM for less than $100, as long as their ears aren't sensitive to bright, vivid sound signatures. Excellent job Simgot, as always!

Pairing recommendation/s:

• Source: This IEM does not need an expensive, or too powerful dongle to be fully utilized. A neutral, or a warm sounding dongle would fit with this set. Their own Simgot DEW4X fits this so well.
• Eartips: The stock eartips included decent enough for the most part. You may still use your preferred eartips.
• Cable. The cable is good and sturdy enough for daily usage, but you may still use your preferred cable.

• Cable material: High quality OFC wrapped shielding layer
• Connector: Type-C
• Output Power: 70mW (3.5mm) & 150 mW (4.4mm)
• Output plug: 3.5mm,4.4mm

=================================================================================================================
Sound signature:

• Simgot designed this dongle to pair with neutral or bright-sounding IEMs. This means that the Simgot DEW4X exhibits a neutral-warm sound signature, that adds a tinge of warmth to the mids, making things sound a bit more bodied than usual. Despite exhibiting this effect, this by no means ruin or affect the overall setup’s sound in any way.

Build Quality:

• Build quality on this dongle is well-done. No seams or creaks are heard or present. Tactile, independent volume buttons are crisp and double as a gain switch when pressed at the same time. There is an RGB indicator and can only be seen through the dongle’s ports. They could’ve put a tiny hole on the top plate of the dongle in my opinion but it is what it is. Anyhow, the RGB indicators also indicate if you’re using it in max volume and what type of mode you are using. These “features” aren’t seen easily on the manual provided and are only seen at the bottom of the packaging.

Device Compatibility:

• This works on all devices I have, whether it be desktop PCs or smartphones. No driver is also needed to use this dongle in its optimal state. I did noticed also that the amount of power of this dongle is slightly lower when paired with a smartphone, which in returns affect the battery consumption positively.

Battery Consumption:

• This IEM is quite thrifty in terms of power consumption. My phone went from 100 to 94% after 1 hour of usage and it lasts for about 5-6 hours when paired with a smartphone with 3000 mah battery.

Power and volume:

The Simgot DEW4X exhibits a good amount of power for IEMs, even on the most hard to drive ones like Planar IEMs and the likes. This is more than enough for most earphones, but if we’re looking in a bigger picture this is slightly lower compared to the dongles currently available in the market for its asking price. Here are some of the IEMs I have tested the DEW4X with this dongle (Legend: Physical buttons are maxed at 30/30, which equates to 100% in this dongle)

• Etymotic ER3SE - 25/100
• Temperament X6 - 22/100
• QKZ X HBB Hades - 40/100
• Simgot EM6L - 15/100
• Simgot EA500 LM - 12/100
• Tanchjim One - 20100
• Letshuoer DZ4 - 15/100
• 7Hz x Crinacle Zero:2- 12/100

=================================================================================================================
Pros:

• Unusual, warm-sounding DAC! (if we’re talking under 100 USD, at least)
• Neutral-warm sounding DAC.
• Excellent overall build quality!
• Independent volume control buttons!
• Has a high-gain mode!
• Has balanced and SE ports!
• DSD support!
• Has UAC modes!
• Pitch-black, noise-free background.
• Relatively low battery consumption.
• No app/extra drivers needed to sound the best!
• Plug and play!

Cons:

• Power output is a bit lower when paired with a smartphone compared to a laptop/desktop-DEW4X pairing.
• RGB LED indicator is only seen through the BAL and SE ports and is not seen at a glance.
• Gain modes and other features are only indicated at the bottom of the packaging.
• May not be as “transparent” as other dongles in the market in terms of rendition.
• A case or a pouch would’ve been a great treat for everybody.

=================================================================================================================

In my humble opinion, the Simgot DEW4X is one of those unique USB DACs under 100USD not because it is “the best among all of them”, but because it is the “best” warm sounding USB DAC I have heard under 100USD. This is also due to the fact that there are only a handful of warm-sounding dongles that exist under 100USD, and most of them are mediocre or underwhelming and hinders the earphone’s optimal performance in terms of technical performance. A well-done dongle, Simgot!


Who is the Simgot DEW4X for?

• For those people who want and need a warm-sounding USB DAC.
• For those people who use neutral and/or bright sounding IEMs/flathead earbuds.
• For those people who want a plug-and-play DAC.
• For those people who want a DAC with a thrifty power consumption.
• For those people who want to add a bit of thickness to their pairing’s overall sound.

Why should you not buy the Simgot DEW4X?

• If you need a “technical performance-oriented” USB DAC.
• If you want extra juice for your setup (ex. 300mw or more)
• If you need RGB LED indicators that can be seen easily.

Setup configuration: Hidizs S9 Pro paired with phones/laptop/pc.

Essential Product Specifications:

• DAC: ES9038Q2M
• DSD native DSD64/128/256/512
• PCM support up to 768kHz/32Bit
• Build quality: CNC aluminium alloy integration (black, silver)
• Transmission interface: Type-C
• Rated output power (SE): 100mW@32Ω
• Frequency response (SE): 20-50kHz
• Signal-to-Noise Ratio (SNR) (SE): 120dB (@32Ω)

• Signal-to-Noise Ratio (SNR) (BAL): 119dB (@32Ω)
• Channel separation (BAL): 118dB (@32Ω)

============================================================================================
Sound signature:

• In Hidizs fashion, the S9 Pro exhibits a neutral, near-transparent, analytical sound rendition. This also means that this dongle will render the setup’s very best (or worst) sound it can produce. As for the technical performance, it does render things nearly transparent, with the exception of the soundstage and layering due to some mild added depth and separation to the sound with a nice, clean, pitch black background, making it somewhat “pseudo-immersive” to my ears. It can be a bad thing for purists, but not for me because it doesn’t “color” the sound that much and will only be noticed when compared with a transparent-rendering dongle side-to-side.

Build Quality:

• Hidizs always love crafting their products with sleekness and elegance, and it shows here in the S9 Pro. It is basically a glass sandwich with an aluminum chassis, making it a light dongle compared to what it seems. There are no physical buttons in this dongle, LED indicator is shown within the dongle’s logo and lits up in different colors depending on the file type played with it. BAL and SE ports are placed up top, but the BAL port is utilized with a 2.5mm female port, which is quite unusual in today’s setting. However, a BAL port is a BAL port, which is nice to have for those cases where it is needed.

Device Compatibility:

• Just like the recent dongles I have tested and owned, This dongle is plug and play - no apps and requirements needed. The simplicity of this area also means that this doesn’t have any bit-perfect mode, sound filters, EQs, and presets. I personally prefer it to be this minimal while sounding in its optimal state, but you do you. 100mw is also the base power output of the SE port, and is more than enough for all the IEMs I have tried and tested with this dongle, while maxing out on 200mw with the 2.5mm BAL port used.

Battery Consumption:

• This dongle is slightly high in terms of battery consumption. It drains about 20% of battery in an hour when paired with a smartphone at most, depending on the file type and gain that you are using. It drains around 30% when used with the 2.5mm port. Due to its high battery consumption, I prefer using this DAC with my laptop.

Power and volume:

• The Hidizs S9 Pro is based on my tests and experience, more than enough for all of the IEMs I have owned and tested, despite it having low number in specifications on paper (others have 240mw of power in BAL mode, to give you and idea) Here are some IEMs and earbuds I have tried with their respective listenable/ enough volumes (do take note that this dongle does not have any independent hardware volume buttons and relies on the smartphone/laptop’s software/hardware volume (100% = 100% max software volume):

• Etymotic ER3SE - 30/100
• Temperament X6 - 30/100
• QKZ X HBB Hades - 35/100
• Simgot EM6L - 12/100
• Tanchjim One - 15/100
• Letshuoer DZ4 - 15/100
• Simgot EA500 LM - 12/100

============================================================================================
Pros:

• Neutral, analytical-sounding USB DAC!
• Nearly transparent rendition.
• More than enough for all IEMs I have tested in terms of power output!
• “Pseudo-immersive” soundstage and layering rendition.
• Sleek, minimal design.
• No need of any drivers and app to sound optimal!
• Jacked up file format/type support (DSD512)
• Lightweight!
• SE and BAL outputs!
• Well-thought LED design!
• Very good amount and quality of included accessories!
• Noise-free, “pitch black” background.

Cons:

• Near-transparent rendition of sound is always a double-edged sword.
• No physical volume control.
• 2.5mm BAL in this hobby full of 4.4mm users seems unusual.
• No app and filters designed for this DAC may not favor those who want customization (not me tho, so it’s subjective)
• Higher than usual battery consumption.
• Physically warms up earlier than usual compared to the dongles I have used and owned.
• It can be a hassle for novice users because the included cable only works when the other end with the brand’s logo is connected to the laptop/smartphone/DAP (might be an isolated case, but there’s that)

============================================================================================

Despite being released for a while now, the Hidizs S9 Pro held up well in today’s “audiophile” market! Not to mention it is greatly reduced in price, which makes it more competent when compared to the dongles existing within the 150 usd and below segment. This is no surprise to me because Hidizs has been always known to be one of the go-to brands for very good quality USB DACs and DAPs for the past years. However, not all DACs are perfect and this has tiny quirks I have mentioned that is up for you to embrace, or avoid. In a nutshell, I find the Hidizs S9 Pro to be my daily driver USB DAC for my laptop. Good job, Hidizs!

Who is the Hidizs S9 Pro for?

• For those people who want an analytical, neutral sound.
• For those people who want a noise-free listening experience.
• For those people who wants a dongle with a detachable cable.
• For those people who want a very lightweight usb dongle on-the-go.
• For those people who do not want to mess with any app or setting just to achieve optimal sound quality.

Why should you not buy the Hidizs S9 Pro ?

• If you don’t want a minimalist design.
• If you don’t want a neutral sounding dongle.
• If you need physical volume controls.
• If you don’t want a battery-depleting dongle.
• If you need a 4.4 BAL port.
• If you are a purist who wants pure transparency.
• If you need extra features such as filters and modes.

IEM/Earbud/Setup configuration: Stock medium eartips, any form of EQ or MSEB off, 40-60% volume. ============================================================================================
Sound signature:

• The CCZ BC04 still follows its house sound, which also means that this IEM is a warm, V-shaped sounding set that leans to the “fun” side, in terms of elevation of both ends of the spectrum.

Lows:

• Just like most of their IEMs (and most of the IEMs found in this price range (under 30USD), this region is the highlight of this IEM. It is a subbass-dominant, bassy set. Subbass rumbles nicely and is evident on bassy tracks or pop genres. Attack and decay speeds are average for an IEM under 30USD and nothing to write home about. “Audiophiles” and “purists” may find it “sloppy” and “lacking of texture” to their liking, but for most people who will be using the CCZ BC04 as an everyday carry or daily casual IEM, the overall region (and sound) of this IEM will never be a problem.

Mids:

• Warm and thick are the two words I first thought when I heard the region of this IEM. It is smooth and exhibits a bit of added depth on male vocals. This also means that this set suffers midbass bleed and has a slight veil on certain instances. Upper mids are elevated and exhibits a good amount of clarity, air, and sparkle. Most of the time, the upper mids of this set does not suffer from peaks and pierce, but I have experienced some “grittiness” on poorly mastered tracks. This isn’t a deal breaker for this IEM, but should be watched out by those people who have very sensitive ears.

Highs:

• Moving on to the treble, it is well-extended, has a sufficient amount of air, and has a decent amount of clarity. I haven’t experienced any harshness or sibilance in this region, which is a good sign. Detail retrieval is average on the BC04, it has good rendition of most details but nothing to write home about.

Soundstage, Imaging, and separation:

• As for the soundstage, the CCZ BC04 has your usual IEM soundstage wherein it is wider than deep with an average height. Separation and layering is average with minor congestion on heavy passages. Imaging is accurate and can render vocal and instrument position easily. It is also good enough for competitive gaming, if that matters.

============================================================================================
Other IEM Comparisons!

VS KZ Castor (Harman)

• The KZ Castor (Harman) leans to a more “neutral” / u-shaped approach. The BC04 definitely has more bass quantity and treble elevation, but the Castor Harman has better mids presentation and technical performance.

VS KBEAR Rosefinch

• The KBEAR Rosefinch is a basshead set and has more bass punch and rumble compared to the BC04, but lacks the treble extension and air that the BC04 has. Technical performance is more or less the same between the two sets.

VS Salnotes Zero

• The Salnotes Zero also has more bass compared to the BC04, and exhibits a warm, “organic” character in its overall sound. Treble has more air and extension on the BC04. Technical performance between the two are more or less the same.

============================================================================================
Pros:

• Fun, all-rounder sound signature.
• Warm, smooth sound.
• Subbass-dominant low frequencies.
• Thick, smooth mids.
• Non-fatiguing upper frequencies.
• Very good soundstage width.
• Sufficient imaging capabilities (particularly on gaming).
• Very good fit, comfort and isolation.
• Very good amount of accessories for a budget set!
• Easy to drive, does not need any high gain or extra amplification.

Cons:

• Midbass bleed is present and exhibits a mild veil on lower mids.
• Keen ears may want additional bass texture and tightness.
• Upper mids may sound “unrefined” on certain tracks.
• Separation and layering may experience congestion on heavy passages.
• A case or a pouch would’ve been a good treat for everybody.
• Sounds good for a budget EDC, but does not bring anything new to the table.

============================================================================================
The CCZ BC04, just like the company’s other sets, aimed for a mass-appealing, EDC-worthy budget IEM. Its fun sound signature will work for most music listening sessions, whether it be during commutes or during chores. If we’re looking to it as a hobbyist-oriented set, this will be a sidegrade, or even a “skippable” set due to its redundant sound. I can recommend the CCZ BC04 for those people who want a budget EDC, but can be skipped by the “audiophiles” who want the latest and greatest, mind-boggling, technical marvel, graph-worthy IEM they could think of.

Pairing recommendation/s:

• Source: This IEM is fairly easy to drive, but will benefit greatly from a neutral sounding source, to trim down some of its warmth.
• Eartips: The stock eartips included decent enough for the most part. You may still use your preferred eartips.
• Cable. The cable is good and sturdy enough for daily usage. You may still use your preferred cable.

• Noise Floor - <1μV
• Supported Formats - PCM (up to 32bit/384kHz), DSD (DSD256, DSD128, DSD64)
• Indicator Lights - PCM (blue), DSD (red)

============================================================================================
Sound signature:

• Just like the Tanchjim Space I own, this is a neutral, analytical set, but is not as transparent when compared to the Space. However, their differences aren’t really that big or substantial, making the Allegro a more “practical” dongle for most IEMs. My etymotic ER3SE and Letshouer DZ4 sounded dead flat on this dongle.

Build Quality:

• I personally like what they did on this dongle in this area - it is very unique and a visual candy since you don’t usually see this type of design in today’s USB DAC scene! The smooth, rounded corners, the chunky design, the tactile buttons - speaks premium. It’s a shame however, that they missed the opportunity to make the retro gamepad buttons functional, like the D-pad as the volume control, and the A/B buttons as gain switches or playback buttons. But who knows, they might implement that on their future DACs or dongles. It gets warm to touch after a long period of time, just like most IEMs I have tried within the 100 USD and under category. The cable is nicely built as well, looks and feels similar to the Tanchjim Space cable.

Device Compatibility:

• This dongle is plug and play - no apps and requirements needed. The simplicity of this area also means that this doesn’t have any bit-perfect mode, sound filters, EQs, and presets. I personally prefer it to be this minimal while sounding in its optimal state, but you do you.

Battery Consumption:

• This dongle is quite average in terms of battery consumption. It drains about 10% of battery in an hour when paired with a smartphone at most, depending on the file type and gain that you are using. It drains around 10-15% when used with 4.4 port. I also noticed that the Allegro has more power to deliver when plugged into a desktop/laptop PC when compared to it plugged in a smartphone. This can be an isolated case.

Power and volume:

• The Kiwi Ears Allegro is enough for most IEMs - even on planar magnetic and other hard to drive IEMs. Here are some IEMs and earbuds I have tried with their respective listenable/ enough volumes (do take note that the volumes indicated are only based on adjusting the hardware volume buttons to 5 steps from its factory hardware volume setting, with the software volume variable. 100% = 100% max software volume):
• Etymotic ER3SE - 40/100
• Temperament X6 - 50/100
• QKZ X HBB Hades - 60/100
• Simgot EM6L - 20/100
• Tanchjim One - 30/100
• Letshuoer DZ4 - 30/100

============================================================================================
Pros:

• A neutral-sound, fairly powerful dongle!
• Neutral, nearly transparent sound.
• Very clean, noise-free, black background.
• Fairly powerful for its asking price.
• Independent volume control!
• 3.5 SE and 4.4 BAL ports!
• Precise, volume buttons!
• Up to DSD256 support!
• LED indicator.
• Unique, retro console look!
• Sturdy, well-built overall build quality!
• Well-built included cable!
• Plug and play, no drivers and apps needed!
• Average battery consumption.

Cons:

• No high gain mode.
• The LED indicator is oddly placed at the bottom side of the dongle, making it practically useless if you ask me.
• The retro console buttons are not functional, but only a design.
• Lacks additional filters such as filters, bit-perfect mode, which may be a necessary for those dongle enthusiasts (subjective)
• Power delivery from phone to dongle is mildly lower compared to the dongle plugged into Desktop PC/Laptop (might be an isolated case, subjective)
• The dongle will be warmer to touch after quite some time (this is normal for dongles I have tried under 100 USD, still subjective)
• A pouch or a case would’ve been a nice treat for everybody.

============================================================================================
The Kiwi Ears Allegro is definitely one of my current top recommendations if you’re looking for a neutral sounding USB DAC under 100USD! Its neutral, nearly transparent-sounding DAC will fit most IEMs and setups easily as this does not boost any frequencies. This is shockingly close to the Tanchjim Space to my ears, and is only behind in terms of power delivery, features, and transparency. In a practical perspective, this is worthy to be a daily driver. And yes, this will definitely stand out in a world full of simple bar dongles. Well done Kiwi Ears!

Who is the Kiwi Ears Allegro for?

• For those people who want an analytical, neutral sound.
• For those people who want a noise-free listening experience.
• For those people who wants a dongle with a detachable cable.
• For those people who want a very lightweight usb dongle on-the-go.
• For those people who do not want to mess with any app or setting just to achieve optimal sound quality.

Why should you not buy the Kiwi Ears Allegro ?

• If you don’t want a non-minimalist design.
• If you don’t want a neutral sounding dongle.
• If you need extra features such as filters and modes.

IEM/Earbud/Setup configuration: Stock medium eartips, any form of EQ or MSEB off, 40-60% volume.

============================================================================================
Sound signature:

• - Just like most HBB collab sets, the Hades follows the same HBB signature wherein bass is the highlight of the show, which is tuned according to his preferred genre. In a nutshell, this IEM is a L/V-shaped fun, smooth, thick, basshead set.

Lows:

• - HBB-tuned sets have always been an IEM tuned for bassheads at heart (and ears), and the Hades is no exception. The bass is definitely elevated on this set, and both midbass and subbass are greatly elevated in this region. It is thick, boomy, and smooth in character, and the decay and attack lean to the slower side of the spectrum. Overall, the bass on this set is definitely for the bassheads, particularly those who prefer the same genre as HBB, which is hip-hop, rap, pop, EDM, and the likes. I enjoyed listening to UK Garage on this set!

Mids:

• - Due to its basshead level of elevation, the mids of the Hades is greatly affected, which can be a good or a bad thing depending on one’s preference. It is definitely recessed, suffers midbass bleed, and has a noticeable veil on vocals and instruments. Lower mids are warm, smooth, and thick. Upper mids are ever so slightly elevated, with a decent amount of clarity, but lacks the air and sparkle to my liking. This also means that I haven’t experienced any form of harshness and sibilance in this area, and I can confidently recommend this set for those who do not want to experience any form of harshness. Overall, the mids of this set is smooth and laid back, which can also greatly improve with additional volume and power.

Highs:

• - The treble also blends well with the rest of the frequencies - it is non-fatiguing, borderline dark, and lacks air to my liking. Microdetails are quite absent on this set for the most part and will only show the more volume or power you feed it, making this IEM not recommended for clinical listening as intended based on what I see (and hear), at least. On the positive side, this will be a good set for easy and casual listening for long sessions.

Soundstage, Imaging, and separation:

• - Just like the other frequencies, this part of the overall sound is heavily affected negatively to my preference, particularly on the separation and layering as it sounds quite cramped on heavy passages. The soundstage exhibits good height, width, and depth. Imaging is accurate enough for casual usage.

============================================================================================
Other IEM Comparisons!

VS 7Hz Legato

• - The Legato is the slightly expensive alternative for the Hades, to put it simply. Their differences are very minimal and are only heard when heard side-by-side. The Legato is better in build quality due to its shells being metal in material, and its accessories.

VS Kiwi Ears Cadenza

• - Both exhibits the same warm character, but the Cadenza leans to the neutral side of the spectrum. Its overall tonality is better when compared, particularly its mids. Their technical performance is identical to my ears. The Cadenza is not as bassy compared to the Hades when compared.

VS Simgot EM6L

• - Their price difference also says it all, the EM6L is the better set between the two, at the expense of sounding “too normal” to some enthusiasts due to its Harman-ish sound. Everything sounds better on the EM6L, from its bass quality down to its clarity and technical performance.

============================================================================================
Pros:
- Fun, bassy signature (subjective)
- Bass-centric sound for pop and EDM genres.
- Thick, smooth, overall bass response.
- Rumbly, big bass response.
- Smooth, thick mids.
- Non-harsh upper frequencies.
- Sound quality scales with additional power/volume.
- Very good fit, comfort, and isolation (for medium-large sized ears).
- Eye-candy IEM appearance.
- Eye-candy packaging!

Cons:
- Heavy midbass bleed that drowns/veils vocals and details significantly.
- Bass is nearly monotonous.
- Bass is boomy and sloppy in character.
- Treble is borderline dark.
- Treble lacks air.
- Technical performance is affected significantly, particularly on separation.
- Needs a bit more volume/power than usual to sound good.
- Accessories are quite underwhelming for its asking price in terms of quantity and quality.
- Overall packaging/presentation is not fitting on the model naming (very subjective).
- IEM shells may not fit smaller ears (subjective)
- Overall sound is genre-dependent (subjective)
============================================================================================
Before you put your pitchforks and probably point my listening preferences, I am here to say that I quite enjoyed this set for most mainstream genres and playlist, and I believe that HBB really tuned this set for those genres he mostly listen, at the expense of sounding “normal” in the audiophile hobby. Despite being an unusual set for most, these types of IEMs exist for a group of people who need the unusual out of the norm. After all, personal enjoyment should matter more than anything else. If you prefer that chunky, smooth, big bass, this one’s for you!

Pairing recommendation/s:

• Source: This IEM is one of those IEMs in the market that needs additional power to shine, because this IEM sounds underwhelming when underpowered, or in low volumes. I prefer using a neutral, fairly powerful source for this set, like the Tanchjim Space for example.
• Eartips: The stock eartips included decent enough for the most part. You may still use your preferred eartips.
• Cable: The cable is good and sturdy enough for daily usage, but it is quite flimsy and thin in quality for its asking price. You may still use your preferred cable.

• - Fosi Audio DS1.
• - Sony Xperia X Compact
• - Local Files via Foobar, YouTube Music, Deezer, and Qobuz with UAPP.

IEM/Earbud/Setup configuration: Stock small eartips, stock dual-flange eartips, any form of EQ or MSEB off, 40-60% volume.

==============================================================================================================
Sound signature:

• - Just like the majority of the IEMs under 15 USD, this is a bassy, V-shaped sounding set, and can also sound L-shaped, depending on your setup and hearing perception. What makes this different from the IEMs within this price point is that this is a well-done, non-fatiguing IEM in a bullet-shaped driver enclosure at the expense of “okay” technical performance.

Lows:

• - This is without a doubt the highlight of this tiny bullet, owing to the fact that it is the most elevated of all the regions of the spectrum. It's elevated, thick, and will sound boomy in most genres. It is also midbass dominant and has a soft quality to it. Its bass is slow and may sound "sloppy" on certain tracks. Having said that, this can be a budget basshead's dream, but it will sound "dirty" to those who have previously used a bassy IEM with a textured, detailed bass response.

Mids:

• - In this region, the NiceHCK is warm, thick, and lush. This also means that this set will be lacking in texture, openness, and detail if we don't consider the fact that it is only 10-15 USD. Upper mids are slightly elevated, with good clarity. This never sounded harsh or peaky to my ears, and some people who prefer more presence over their preferred sound may find this lacking. Overall, I had no serious issues with the X39 in this region because it is fatigue-free and smooth, despite my lack of preferences in this set.

Highs:

• - Moving on to the treble, this region is not airy, does not extend much like the other sets in this price range, and will sound rolled off, particularly for those who prefer a brighter, airier response. Detail retrieval is average at best, rendering the majority of the track's details.

Soundstage, Imaging, and separation:

• - In a nutshell, the technical performance of the NiceHCK X39 is quite underwhelming to my preference. Its soundstage is small in width, with average height and depth. The separation and layering is average most of the time and suffers congestion on very busy tracks. Imaging is also average and can be used with competitive FPS games with sufficient accuracy.

==============================================================================================================
Other IEM Comparisons!

VS KZ Ling Long

• - The KZ Ling Long is also a v-shaped bassy set, but is lesser in bass quantity compared to the X39 and is subbass focused compared to the X39’s midbass-focused character. Mids are more or less the same, except for the fact that the Ling Long is prone to peaks. Treble is also identical. The soundstage is a bit wider on the Ling Long, while the rest are identical. The KZ Ling Long suffers some driver flex, while the NiceHCK X39 doesn’t.

VS Tanchjim Zero

• - The Tanchjim Zero is flatter, uncolored, a tad bit wider compared to the X39 in terms of overall sound. Its mids are miles better when compared, in exchange for a polite, tight bass. The Tanchjim Zero also needs a bit more power to sound good compared to the X39.

VS KBEAR KW1

• - The KBEAR KW1 also shares the same sound signature to the NiceHCK X39. When compared, the KW1 has an obvious veil to the sound, making things muffled compared to the X39 that only suffers muffled vocals. Soundstage is wider on the KW1, while the rest are more or less the same.

Pros:

• Portable, bassy bullet-shaped IEMs on a budget (around 10-15 USD)!
• Bassy, warm, V/L-shaped sound signature (subjective).
• Thick, elevated bass response.
• Thick, smooth mids.
• Non-fatiguing upper frequencies.
• Average technical performance for its price.
• Excellent build, comfort, and isolation!
• Very good quality of accessories.
• Minimal, low profile design! (subjective)
• Easy to drive.

Cons:

• Midbass bleed is definitely present on most genres and my test tracks.
• Bass leans to the boomy side of the spectrum.
• Vocals will sound muffled at times (to my liking, at least).
• Treble is borderline dark.
• Treble lacks air.
• Not the most resolving IEM within this price point.
• Separation and layering suffers mild congestion from busy/heavy passages.
• The included eartips (aside from the included dual flange) cripples the overall sound.
• Non-removable cable.
• Mild cable microphonics.
• They could’ve chosen to include a pouch or a case for practical reasons, but they chose to include a keychain, because why not?

==============================================================================================================

- Despite all of my nitpicks and criticisms of the NiceHCK X39, I genuinely enjoy this set because of its "easy-going", blunt, fatigue-free sound, which I usually require when I need to focus on something. Not to mention that this is a minimalist, low-profile, portable set, which is very useful for my purposes because it allows me to focus more on what is going on around me when I walk through malls or ride in vehicles during commutes. The NiceHCK X39 will never be a part of the hype train or the Chi-Fi hall of fame, which is fine because it performs slightly better than the common, unbranded earphones found in dollar stores, which is already a good job, at least for me.

Pairing recommendation/s:

• - Source: This IEM is fairly easy to drive, but will benefit greatly from a neutral sounding source, to trim down some of its warmth.

• - Eartips: Aside from the dual flanges included, the stock eartips included on this IEM cripples the sound. I suggest changing eartips such as the KBEAR 07 or spinfit CP100 eartips. As usual, you may also use your preferred eartips.

IEM/Earbud/Setup configuration: stock earbud foams, any form of EQ or MSEB off, 40-60% volume.

============================================================================================
Sound signature:

• Just like most of the Ksearphone earbuds I have owned and loaned, the Temperament X6 presents itself in a neutral, clean manner. If we’re being specific, the Temperament X6 is a neutral-sounding set, mildly leaning to the brighter side of the spectrum.

Lows:

• - The X6 produces a good amount of bass in terms of quality and quantity, which I prefer at this price point of less than $50. It only elevates when the track requires it, showing how balanced its bass presentation is. The midbass punch is more prominent than the subbass rumble, resulting in a punchy and clean bass. This also means that the decay is leaning to the faster side. Overall, the bass on the X6 is a significant improvement over the previous LBBS, at least from what I recall. I'll never forget how the previous LBBS sounded lacking and limp in bass when I played my favorite bassy tracks with that earbud.

Mids:

• - Despite not being elevated, this is the highlight of this earbud in my opinion due to its clear, immersive quality. The entire midrange is immersive, clean, transparent, and free of any midbass bleed or bloat. Lower mids maintain a good level of thickness and depth without sounding too thin. The clean, neutral sound did not deter from the details or texture. Upper mids are slightly elevated, with an airy, clear, and crisp character. I didn't hear or feel any harshness or sibilance, but people with sensitive ears may find this "too bright" if they're not used to a neutral-bright sound signature. Overall, I love how the mids of the Temperament X6 sounds due to its bleed-free, clean, detailed character, but it will not be for everyone, especially to those people who prefer V/U-shaped sound signatures.

Highs:

• - The treble is well-extended, airy, and full of detail. This area is not as elevated as the upper mids, according to my hearing. Cymbals are "crispy" here, with plenty of definition and decay. Detail retrieval is above average, making microdetails much easier to hear. Trebleheads will be happy and satisfied with the Temperament X6’s treble, but as expected, people with sensitive ears may find it “too bright”.

Soundstage, Imaging, and separation:

• - This region is where the Temperament X6 excels the most, along with its mids. Everything sounds immersive and well-layered for its asking price, even on the most busy passages on my test tracks. The soundstage is wide and immersive, exhibiting good height and depth. Separation and layering is clean and transparent, presenting busy tracks and passages with ease. Imaging is precise and gives this “pseudo-headphone” like effect to my ears most of the time.

============================================================================================
Other Earbud Comparisons!

VS NiceHCK EB2S Pro

• - The EB2S Pro sounded a bit thin when I compared this with the Temperament X6. The mids were more elevated and prominent on the EB2S Pro. Bass is better in quantity on the X6. Treble is more detailed on the X6 when compared. The stage is a bit wider on the EB2S Pro but lacks the X6’s height and depth. Separation and layering is better on the X6 as it threads better on heavy passages. Imaging is more or less the same.

VS NiceHCK EB2S

• - The EB2S is definitely warmer and bassier compared to the Temperament X6. The rest of the comparison is identical to the EB2S Pro vs Temperament X6.

VS Ksearphone LBBS

• - The Temparament X6 is a “refined refresh” of the previous LBBS in my opinion. The bass here on the X6 is better both in quality and quantity compared to the LBBS. The mids were also a bit thicker and more elevated when compared. Brightness was also trimmed down when compared to the LBBS, exhibiting nearly zero sibilance and harshness unlike the previous model. Technical performance is a bit better on the X6 due to its better height and depth.

============================================================================================
Pros:
- Currently the “best” relatively neutral-sounding earbuds under 50 USD!
- A refined, more “ear-friendly” version of the previous LBBS in terms of sound.
- Clean, neutral sound signature.
- Non-lacking bass quantity for an earbud.
- Clear, open, immersive mids
- Excellent vocal presentation for its asking price.
- Airy, well-extended treble.
- Excellent technical performance, particularly on separation and layering.
- Has two options of wearing for a nearly universal earbuds fit.
- Patented, “modular” design.
- Excellent build quality for an earbud!
- Very good quality of accessories.
- Easy to drive.

Cons:
- While not experiencing any peaks or sibilance, some ears will still find this as too “bright” due to its neutral, airy sound.
- Despite having adequate amounts of bass quantity, some ears may find it lacking in terms of texture.
- IEM users who are not used to using flathead earbuds may find the sound “thin”.
- L/R indicators are non-intuitive during the first sessions/hours of usage.
- Its “patented” modular design is quite pointless in my opinion.
- A hard case would be nice for its asking price since this is an earbud with an uncommon modular cable design.

============================================================================================

The Temperament X6 is currently my top Earbuds recommendation under 50 USD! If we’re talking in a practical sense, this is the only earbuds you need before spending a 200-300 USD earbud, or actually buying a decent pair of headphones such as the Sennheiser HD600, for a better sound quality. Unlike the Chi-Fi IEM market, the sound of this set is noticeably refined and does not resemble any similar earbud. Despite all the complaints I listed on the “Cons” section of this review, I can happily recommend the Temperament X6 to everyone in the hobby who prefers flathead earbuds, assuming that they don’t have any problem with brightness in sound.

Pairing recommendation/s:

• - Earbud foams: Full foams will add more depth in exchange for a less clearer mids. Earbud foams will retain the mids wile adding bass.

• - Source: This earbud is easy to drive, but will sound better on warmer sources. I had no problems pairing this with my Tanchjim Space and Fosi Audio DS1 since this pairing checks out what I prefer, but this definitely benefits from a warmer sounding source like the Whizzer DA1 or Tempotec Sonata BHD Pro.

• - Cable: Technically, the cable of the Temperament X6 is replaceable with their own “patented modular cables” which is the portion of the cable from underneath the y-split below. This is quite pointless in my opinion since it is proprietary and costs almost the same as the whole product here in our country, but it is possible.

Setup configuration: Tanchjim Space paired with phones/laptop/pc.

============================================================================================
Essential Product Specifications:

• - Headphone port: 3.5mm SE / 4.4mm Bal
• - Input port: USB Type-C
• - Frequency response: 6hz-85kHz
• - Background noise: 1.3uV(BAL), 1.1uV(UNBAL)

• - Output power: 4Vrms (BAL High), 2Vrms (BAL Low), 2Vrms (UNBAL High), 1Vrms (UNBAL Low)

============================================================================================
Sound signature:

• - The Tanchjim Space exhibits an analytical, reference, transparent/uncolored sound that focuses more on utilizing the gear and the audio file’s optimal sound quality. This also means that this DAC is a “revealing” set, which can be a good or a bad thing depending on the user. It will reveal how wide or narrow an IEM/earbuds sound, how well layered the whole track is, how muffled or clear the files played with it, and the likes. I can clearly hear how compressed Spotify sounds, and how “rich” or clean Deezer, Qobuz, and my ripped CDs sound on this dongle. YouTube Music sits in the middle in terms of sound quality, and is the most practical among the file types/streaming platforms I’ve tested to my liking.

Build Quality:

• - I personally like what they did with the Space - it is very light in weight without skimping on the build quality. The design exhibits a sturdy,industrial-type of motif in a sleek, minimalist, gray color. It is also smaller in height and a bit wider in width as well, which makes it more portable compared to other dongles I’ve tested and loaned.

Device Compatibility:

• - Just like the Fosi Audio DS1 which is my current daily driver for a year and a half, this dongle does not need any proprietary app to sound in its optimal sound quality, making it very easy to connect across all of my android and windows devices. Hardware volume control is also detected in UAPP, and is easily detected on UAPP, Hibymusic, and Eddict player.

Battery Consumption:

• - This dongle is quite average in terms of battery consumption. It drains about 6-10% of battery in an hour when paired with a smartphone at most, depending on the file type and gain that you are using.

Power and volume:

The Tanchjim space was sufficient (and even more than enough at times) on delivering power and volume on all of my IEMs and earbuds. It has a high gain mode on both BAL and SE connections. Here are some IEMs and earbuds I have tried with their respective listenable/ enough volumes (do take note that the volumes indicated are only based on adjusting the hardware volume buttons to 5 steps from its factory hardware volume setting, with the software volume variable. 100% = 100% max software volume):

• - Etymotic ER3SE - 30/100
• - Temperament X6 - 35/100
• - Simgot EM6L - 20/100
• - Tanchjim One - 25/100
• - Simgot EW200 - 15/100
• - Letshuoer DZ4 - 25/100

============================================================================================

Who is the Tanchjim Space for?

• - For those people who want an analytical, uncolored sounding dongle.
• - For those people who want a distortion, jitter free-sound.
• - For those people who wants a dongle with a detachable cable.
• - For those people who want a very lightweight usb dongle on-the-go.
• - For those people who do not want to mess with any app or setting just to achieve optimal sound quality.

Why should you not buy the Tanchjim Space?

• - If you want a dongle that forgives recording/setup flaws.
• - If you are looking for a warm-sounding dongle.
• - If you mainly use easy-to-drive IEMs (The Tanchjim Space Lite sounds about the same to my ears but with only one SE port, 2vrms max output and no hardware volume buttons).
• - If you need a dedicated app for your dongle.
• - If you care about MQA too much.

============================================================================================
Pros:
- An excellent reference/analytical, transparent-sounding DAC under 100 USD!
- Clean, pitch-black,noise and distortion-free, spacious sound (literally).
- The most “revealing” DAC I’ve used under 100 USD.
- Well-done, powerful output (230 mw @32 Ohms).
- Offers two modes of gain.
- Offers SE and BAL ports.
- Independent hardware volume controls!
- Detachable cable!
- Does not require any app to sound in its optimal performance! (There’s an app but it is buggy as of this moment)
- Does not get too hot unlike most USB DACs.
- Minimal yet intuitive LED indicators!
- Quite tiny in terms of form factor!
- Excellent build quality!
- Visually pleasing appearance!
- Visually pleasing packaging! (subjective).
- Average power consumption.

Cons:
- Having a revealing, transparent sound is a double-edged sword. (heavy emphasis on this one)
- Having an independent volume control also requires at least an - indicator or a tiny screen for me to see what volume step I am in.
- Some people may ask for a well-done, properly-functioning dedicated app for this dongle (I don’t need that as it works excellent without it, still subjective though).
- Cable is visually aesthetic and very durable, but it is quite stiff to my liking.
- A pouch or a carrying case would’ve been nice if included for its price, to prolong the dongle’s overall life span.

IEM/Earbud/Setup configuration: stock earbud foams, any form of EQ or MSEB off, 40-60% volume.

============================================================================================
Sound signature:

• Unlike its previous siblings, the EB2S and EB2S Pro, the NiceHCK YDX leaned slightly to its MX500 (NiceHCK YD30 and Traceless) siblings in terms of soundThe YDX exhibits an all rounder, mild-v sound signature that tilts slightly to the brighter sound of the spectrum.

Lows:

• - The lows on this earbud are a little elevated for an earbud, and it has a punchy character. Its decay is quick, monotonous, and lacks detail to my liking. Because of this type of bass, bleed is minimal to none, resulting in very clear mids. Without a doubt, this is not a "budget basshead's dream," but it will suffice for most tracks as an earbud.

Mids:

• - When describing this region of the set, the words clear, crispy, and open came to my mind. Lower mids are clear, bleed-free, and have a good amount of thickness and texture. On very heavy/busy passages, this region will sound slightly boxy, but on most tracks, it will sound clear and open. Upper mids are light, airy, crisp, and clear. On poorly recorded tracks, this region is prone to mild peaks and excessive harshness, but not to the point where it will be tiring, given that the user is conscious of his/her listening volume level. Overall, this earbuds sounds very goods and enjoyable on most tracks, but excels mostly on vocals and instrument-oriented tracks that I listen to with it.

Highs:

• - This region is definitely elevated, bright, airy, and well-extended. Just like its mids, it will introduce mild peaks on poorly-recorded tracks. Detail retrieval is average and renders most of the nuances and details as is.

Soundstage, Imaging, and separation:

• - As for the soundstage, it is wider than deep, but has a noticeable height and depth. Separation and layering is average for its price and will sound congested on very heavy passages. Imaging is average at best and will render vocal and instrument placement accurately.

Other Earbud Comparisons!

- VS NiceHCK EB2S Pro

• The EB2S Pro is a neutral-midcentric set to me, due to its forward mids when compared. Bass however, has more quantity and elevation on the YDX, but not by a mile. Treble is elevated on the YDX but exhibits the extension the EB2S Pro has. Detail retrieval and technical performance are better on the EB2S Pro, but the YDX has better height and depth when compared.

- VS NiceHCK EB2S

• The EB2S is definitely warmer compared to the YDX. The rest of the comparison are identical to the EB2S Pro vs YDX.

- VS Temparament X6

• The Temparament X6 is a step above in the overall sound compared to the YDX, particularly in the technical department. Everything sounds immersive on that set, as it should be due to its price compared to the YDX.

- VS Faaeal Iris Ancestor

• The Ancestor is a warmer, smoother sounding set that excels on the tonality, while the YDX excels on the technical performance when compared. The Ancestor also need a bit more power to sound “correct”.

- VS NiceHCK Traceless

• The Traceless is a warmer, mildly thicker set, but has a smaller soundstage compared to the YDX.

============================================================================================
Pros:
- A well-done, go-to earbud under 20 USD!
- All-rounder, well done, mild-v sound signature.
- Non-lacking bass quantity for an earbud.
- Tight, elevated lows.
- Clear, open mids.
- Well-extended, airy upper frequencies.
- Average technical performance, a “substantial” step up from Vido earbuds (subjective).
- Very good fit and comfort.
- Removable 2-pin cable connector, something that you don’t usually see on earbuds!
- Very good cable quality!
- Very good quality of accessories!
- Enticing, visually-pleasing packaging and aesthetics (subjective)
- Easy to drive.

Cons:
- Upper frequencies will be prone to peaks/excessive brightness when used without earbud foams (subjective).
- Bass may sound “monotonous” to some.
- Bass may lack texture to some.
- Mids may sound boxy on busy tracks.

============================================================================================

The NiceHCK YDX is definitely added to my “EDC Recommendation” list! Aside for having a really good, all-rounder sound, it is quite practical due to its removable cable, prolonging its lifespan, unlike most earbuds in this price range (under 20USD). This earbuds definitely checks all the boxes of my EDC criteria. Very good quality as always, NiceHCK!

Pairing recommendation/s:

• - Earbud foams: Full foams will add more depth in exchange for a less clearer mids. Earbud foams will retain the mids wile adding bass.

• - Source: This earbud is easy to drive, but will sound better on warmer sources.

• - Cable: is already good as what it is, but you may use what you prefer. Normal 2-pin IEM cables will work just fine with this IEM.

IEM/Earbud/Setup configuration: stock medium eartips, any form of EQ or MSEB off, DSP/USB-C plug, 40-60% volume,
Sound signature:

• The Simgot EM6L, like its brighter-sounding siblings the EW200 and EA500, aimed for a mildly fun, versatile, mild-U/V shaped sound signature, but now added a reasonable amount of lows. What distinguishes this from other Harman sets I've dealt with and listened to is that it manages technical and tonal balance almost evenly.

Lows:

• Despite Simgot's addition of some lows on this set, it isn't as obtrusive or bass heavy as I expected. The bass in this set is very versatile, slightly elevated than I prefer, but quick and adaptable to whatever tracks you throw at it. The lows on the EM6L were never monotonous, overpowering, or overly lean/dry. However, bassheads at heart may find the bass of this IEM lacking in quantity, as it lacks the chunky, boomy, greatly elevated bass of the 7Hz Legato.But overall, I can confidently say that the bass will be enough for most people and hobbyists, and may be more enough for those people who are seeking neutrality.

Mids:

• The mids on the EM6L are open, detailed, and free of bloat and bleed, despite not being the IEM's highlight or focus. The lower mids are notably thick and textured. Male vocals and instruments in this region have excellent definition and thickness. Upper mids are mildly elevated and exhibit excellent clarity, air, and sparkle. There are no unnatural peaks or sibilance in this IEM, which is great news for those with sensitive ears who can't get enough of the "Simgot house sound" but are wary of the EW200 and EA500's prone to sibilance and peaks when the tracks demand it. Overall, despite me being a sucker for a forward mids, I enjoyed the mids on the Simgot EM6L a lot, just like its older siblings mainly because of its resolution and versatility.

Highs:

• The treble here is mildly elevated, but not as elevated as the bass, which means that there are no instances of sibilance or pierce in this region. Trebleheads may find the air on this set slightly lacking in comparison to the EW200 and EA500, but in terms of extension and air, they are nearly identical in my opinion. Microdetails are above average and will easily render subtle nuances.

Soundstage, Imaging, and separation:

• "Excellent and easy-going" were the first words that came to mind when I heard this set. To my ears, this IEM never sounded like it struggled to render the complexity of any tracks I threw at it. The soundstage is expansive and pseudo-immersive, with plenty of height and depth. Separation and layering are excellent for the price, in my opinion, and can compete with sub-200 USD IEMs in this context. Imaging is as precise as ever, slightly more so than on the EA500 and EW200, with good rendition of vocal and instrument positioning.

=====================================================================================================
Other IEM comparisons!

VS Simgot EA500 (Black Nozzles)

• The EA500 is a more analytical, brighter sounding set when compared. Bass is tighter on the EA500 but lacks quantity on some tracks.

VS Simgot EW200

• The Simgot EW200 is also a bit brighter when compared and also has lesser bass. Technicalities are better on the EM6L, but the EW200 isn’t that far. The EW200 is also easier to drive, interestingly.

VS Letshuoer DZ4

• The DZ4 is a safer, more neutral or linear sounding set. It definitely has lesser bass, and less clean separation and layering.

VS Celest Phoenixcall

• The Celest Phoenixcall is a more fun-sounding set with a more “rounded” soundstage, if that makes sense. Bass is more pronounced and chunky on the Phoenixcall, but the EM6L has a more tight and clean rendition.

VS BQEYZ Autumn

• The BQEYZ Autumn sounds more “natural” and mature when compared, while the EM6L is “fun” yet versatile. Mids are more forward in the Autumn while the EM6L makes up for it by exhibiting the same-same thickness and smoothness. Technical performance of the EM6L is on par with the Autumn, mainly on the separation and layering.

Pros:

• Simgot’s most “well-thought” Harman-sounding IEM yet!
• All-rounder, mild U/V-shaped sounding IEM (subjective).
• Just like the EW200, this IEM managed to balance tonal and technical performance relatively evenly.
• Very cohesive sound for a multi-driver IEM.
• Elevated, versatile, well-balanced bass rendition in terms of punch and rumble.
• Open, lively, mildly smooth yet detailed mids.
• Well-extended yet non-fatiguing upper frequencies.
• Excellent, incisive technical performance that goes toe-to-toe with sub-200 USD IEMs.
• Very good fit, comfort, and isolation. Very lightweight yet sturdy!
• Visually-pleasing build quality and aesthetics! (highly subjective)
• Fairly easy to drive compared to the EW200 and scales/sounds better with an external DAC.

Cons:

• Technical performance is definitely excellent for its asking price, but it isn’t miles and leaps ahead compared to the Simgot EW200 and EA500.
• Faceplates are definitely scratch and smudge-prone.
• QDC-type connection may be a downside to some (highly subjective).
• A cleaning cloth and an extra set of eartips would be a good treat for everybody in this price point (definitely a nitpick)

=====================================================================================================
Simgot’s EM6L reminds me of a saying I’ve heard before somewhere: "If you're doing something common, make sure that you’re doing the best version of it”. Despite exhibiting a “common” sound signature, Simgot always pursues “mastering” and “perfecting” their sound target, which is true to their “Phoenix”. Most snobs may find this sound target common, but the sound the EM6L is the best version of “Harman sound” I have experienced and tested within the 150 USD and below, to my ears, at least. Again, well done Simgot!

Pairing recommendation/s:

• Eartips: The eartips are alright and enough for the most part. You may always use your preferred eartips.
• Source: This IEM is easy to drive and will sound good with a phone, but benefits well on a hifi dongle or USB DAC, mainly on its bass rendition.
• Cable: is already good as what it is, but you may use what you prefer. Normal 2-pin IEM cables will work just fine with this IEM, QDC cables will offer a bit more protection though.

IEM/Earbud/Setup configuration: stock medium eartips, any form of EQ or MSEB off, DSP/USB-C plug, 40-60% volume.

(We'll start this review with all of the switches flipped on, as it is the "stock" configuration of the KZ Castor out of the box.)

================================================================================================================
Sound signature:

• - The KZ Castor (Neutral) quite resembles the overall sound characteristic that the KZ EDA (Balanced) had, but greatly improved. It is still a “harman” or mild-u-shaped sounding set, but managed to balance both tonality and technicalities for its price greatly, in terms of quality.

Lows:

• - This region isn't the Castor neutral's strong suit because it isn't the most raised or textured in this IEM. It's punchy and somewhat raised, with a fast attack and decay, yet it can get boring on certain tracks. When compared to the EDA Balanced, it is noticeably thicker and has better decay for most genres, including bassy ones. However, the Castor Bass version is the one to choose if you want a bassy sound while still preserving the Castor naming scheme.

Mids:

• - Now we are at the highlight of this IEM, in my humble opinion. Sure, it is slightly more recessed than the other frequencies, as are most u-shaped IEMs, but it is quite open, clear, and detailed for the price. Male vocal fans may find the thickness of the male vocals missing, but it is usually insignificant and has the details when needed. Upper frequencies are slightly raised, clean, airy, and contain a lot of sparkle. This region will sound "peaky" to sensitive hearing on badly recorded or particularly sibilant tracks, but it will never be sibilant or piercing. Overall, I like the mids of the KZ Castor Neutral and probably it’s their best rendition of their signature mids among all of their products I have auditioned.

Highs:

• - This set's treble is nicely extended and somewhat raised. It's neither sibilant or fatiguing at all, while still retaining the necessary presence of this region. Detail retrieval is average, nothing new or something to write home about. It still has most of the details needed for casual music listening sessions.

Soundstage, Imaging, and separation:

• - Just like the EDA Balanced, the Castor Neutral quite has the balance in terms of technical and tonal performance. The soundstage is better on this set in terms of depth and height, layering and separation is also a bit better but nothing too significant and may struggle on very busy tracks compared to their recently released IEMs. Imaging and separation is very good and very good for listening to live performances and fps games.

================================================================================================================
Switch configurations in a nutshell!

• Just like the first KZ to do the tunable switch feature, the switches here in the KZ Castor exhibits the “add/subtract” type of mechanism. One switch flip equates to a 1db elevation in the low/high frequencies.

================================================================================================================
Other IEM comparisons!

VS CVJ KE-S

• - The KE-S is definitely warmer, smoother, but suffers less treble extension, air, and detail. Technical performance is also better on the Castor Neutral.

VS Tanchjim Zero

• - The Zero is literally dead flat, neutral, and prioritizes the technical performance more than the tonality. The Castor Neutral is a bit behind on the layering, but is on par on all technical aspects when compared. It is also easier to drive when compared.

VS CCA Duo

• - The CCA Duo is a brighter, more peaky IEM. It edges out the Castor Neutral on the detail retrieval and layering, but the rest both IEMs are on par. The Castor Neutral does not suffer in any form of harshness though. It is cheaper as well.

================================================================================================================
Pros:

• - For the nth time, their “best” IEM is under 30 USD yet!
• - The usual, “neutral” sound signature (subjective).
• - Well-balanced sound quality in terms of technical and tonal performance.
• - Well-controlled, smooth bass bass response.
• - Open, detailed mids.
• - Non-fatiguing yet airy upper frequencies.
• - Very good technical performance under 25 USD.
• - Versatile, “KZ-signature” tuning switch.
• - Very good fit, comfort, and isolation.
• - Smooth, sleek “fluid” design! (subjective).
• - Easy to drive.
• - Relatively cheap!

Cons:

• - Due to two existing versions of this IEM, the switch feature is quite pointless or a gimmick (subjective).
• - Bass may sound monotonous at times (subjective).
• - Sound isn't good when all switches are turned off/ some of the switches are turned off.
• - Despite not being sibilant or harsh in any way, people with sensitive ears may prefer the bass version more or look for something else due to its “clean-neutral” sound approach (highly subjective).
• - Barebone accessories.

================================================================================================================

In a very good, positive way, there is nothing significantly new about KZ's current lineup. All of their products are really good, refined, and very capable of sounding great on casual music listening sessions. This KZ Castor Neutral version, in KZ manner, is by far, their best yet and their “for the masses” IEM yet! However, I do find its switch feature rather pointless and definitely a useless gimmick due to the Castor’s dedicated “bass” version. Despite the said gimmick, the KZ Castor is definitely on the top of my budget recommendations if you are looking for a neutral-sounding set, well done!

Pairing recommendation/s:

• - Eartips: The eartips are alright and enough for the most part. You may always use your preferred eartips.
• - Source: This IEM is easy to drive, but benefits well on a Hi-Fi dongle or USB DAC.
• - Cable: is already good as what it is, but you may use what you prefer.

IEM/Earbud/Setup configuration: stock medium clear eartips, any form of EQ or MSEB off, DSP/USB-C plug, 40-60% volume, ================================================================================================================

Sound signature:

• Following the company’s refreshed house sound, the Simgot EW100 DSP is a harman-sounding (u-shaped) set that leans to the warmer side of the spectrum.

Lows:

• This region of the EW100 DSP is the most elevated among all the other frequencies. It is punchy, thick, with a good amount of speed on its attack and decay. Despite being classified as a “bassy” set to my ears, it never sounded soft or muddy even when used with bass heavy genres or tracks. Bassheads on a budget will like this set, but will find this not too bassy if they have listened to the KBEAR Rosefinch and KS2 already.

Mids:

• Despite not being the IEM’s highlight, the mids here are clean and open while maintaining its presence. This is why I described its overall sound as a “well-done Harman”. Lower mids exhibit a good amount of thickness and texture. Upper mids are well-elevated, never sounding sibilant, while maintaining the overall clarity, air and sparkle.

Highs:

• Moving into the treble region, this is also well-extended and never sounded “bright” to my ears, but never sounded “dark” either. It exhibits a good amount of presence, air, and detail.

Soundstage, Imaging, and separation:

• Simgot managed to tune this IEM with a good balance of technical and tonal performance in terms of quality. Soundstage is average, wider than deep, with a good amount of depth. Separation and layering here is average to my ears and sounds clean on heavy passages. Imaging is precise and has no problem rendering positions on both music listening sessions and competitive gaming.

================================================================================================================
Other IEM comparisons!

VS CCA Duo

• The Duo is a brighter, leaner sounding set. EW100 is warmer with up to par technical performance.

VS Tanchjim One

• Both exhibit nearly the same sound, with the EW100 DSP sounding a bit “open” than the One. However, the One excels on the presences of its mids and technical performance by a tiny bit. Its cable is removable too.

VS Simgot EW200

• Despite being made by the same company, The EW200 is better overall when compared. It is cleaner, more detailed, more technical, but leans more on the brighter side of the spectrum. Build quality is also better.

================================================================================================================
Pros:

• All rounder, “well-balanced” sound signature.
• Fun yet clean and “fairly precise” sound.
• Thick, impactful lows.
• Clean, clear mids.
• Non-fatiguing upper frequencies.
• Very good upper frequencies.
• Does not need any extra DAC because the cable has the DAC itself.
• Suitable for all phones that have USB-C as the only port.
• Plug-and-play.
• Very good mic quality.
• Very good fit, comfort and isolation.
• Very light to the ears! (subjective)
• Fairly easy to drive.

Cons:

• May sound “too common” for some hobbyists (subjective).
• Non-detachable cable.
• Barebone accessories.

================================================================================================================

The Simgot EW100 DSP welcomes the modern music-listening area with a practical approach: utilizing the USB-C port while being relatively cheap, in a budget “audio-enthusiast” way. While it may not be the most “unique” product to have ever existed in this saturated, Chi-Fi audio market, it sure is one of the recommendable IEMs as an everyday carry due to its all-rounder, clean sound signature and quality. Well done!

Pairing recommendation/s:

• Eartips: The eartips are alright and enough for the most part. You may always use your preferred eartips.

IEM/Earbud/Setup configuration: stock medium clear eartips, any form of EQ or MSEB off, 3.5 SE plug, 40-60% volume, low gain and high gain.

================================================================================================================
Sound signature:

• The Hidizs MS1 Galaxy sports the usual Hidizs house sound - a fun, mild-v-shaped sound signature. Compared to the MS1- Rainbow, this sounds a lesser in bass quantity.

Lows:

• This region is the highlight of the MS1-Galaxy. It is elevated, thumpy with a good amount of punch and rumble. Midbass and subbass are fairly equal, and are average in terms of attack, decay, and texture. Bassheads on a budget will be happy with this IEM catering their bassy genres.

Mids:

• The mids isn’t the strong suit of the MS1 Galaxy. It is mildly recessed, will sound thin at times, lacks some “openness” and suffers from some midbass bleed, making the lower mids warm but not too much to make it sound congested. Lower mids have good thickness and texture most of the time. Upper mids are slightly elevated compared to the lower mids, with a decent amount of clarity, air, and sparkle. There isn’t any form of sibilance or harshness in this area, which also means that this IEM can also be used with those ears who are sensitive to excessive upper frequencies.

Highs:

• As for the treble, it is fairly extended, but not as elevated compared to its lows. Trebleheads may find this lacking or rolled off, but will be just fine to most people. Detail retrieval is alright for its asking price and is not capable of showing clear microdetails which is fine since this IEM is not made for critical listening.

Soundstage, Imaging, and separation:

• “Mediocre” is the first word that came into my mind when I heard this IEM. Don’t get me wrong, there isn’t anything “bad” in this region of the MS1 galaxy, but this isn’t the strong suit or competitive aspect of this IEM in this price point. The soundstage is wider that deep, with a good amount of height and depth. Separation and layering is average with some congestion on very busy tracks. Imaging is accurate for the most part, and is sufficient enough for competitive gaming.

================================================================================================================
Other IEM comparisons!

VS CCA Duo

• The Duo leans to a more neutral, refined sound profile compared to the MS1 Galaxy. It has a lesser bass presence but punches and decays quickly when compared. Mids are more open on the Duo and more detailed, but is brighter and has peaks when compared to the MS1 Galaxy. Treble is also more extended on the Duo. The soundstage is a bit wider on the MS1 Galaxy, but not by much. The rest are better in quality on the Duo.

VS Kiwi Ears Cadenza

• The Cadenza is more cohesive, smoother sounding than the MS1 Galaxy. Both don't have the advantage in technical performance, but the Cadenza is noticeably more lush and rich in sound character compared to the MS1 Galaxy.

VS Simgot EW200

• The Simgot EW200 is better overall in terms of technical and tonal performance. It is more open, airy, detailed, but is brighter when compared. The fit and comfort is better on the MS1 Galaxy though.

================================================================================================================
Pros:

• All-rounder, fun sound signature.
• Fairly controlled, elevated bass.
• Decent mids quality in terms of presence.
• Non-fatiguing upper frequencies.
• Good technical performance for its asking price.
• Aesthetically-pleasing design among all the MS1 variants (subjective)
• Very good, tight build quality!
• Excellent fit, comfort, and isolation.
• Very good mic quality!
• Literally easy to drive.

Cons:

• Mids may sound thin at times.
• Mids lack definition to my liking. (subjective)
• Technicalities are good, but nothing to write home about.
• No in-line volume control buttons.
• Barebone accessories. A pouch and/or a cable winder would’ve been a treat for everybody for its asking price.

================================================================================================================

The Hidizs MS1 Galaxy exists as one of the “options of the many” IEMs due to its all-rounder sound signature. While not be anyone’s first choice, the Hidizs Galaxy MS1 performs well for its asking price and suits well as an everyday-carry IEM since it is very reliable on conference calls and casual music listening on commutes.

Pairing recommendation/s:

• Source: This sounds just fine when plugged straight to a phone due to its easy to drive nature. However, using an external dongle or DAC wouldn’t hurt.
• Eartips: The eartips are alright and enough for the most part. You may always use your preferred eartips.
• Cable gets the job done and is sufficient for the most part. You may always use your preferred cable.

IEM/Earbud/Setup configuration: stock large narrowbore eartips, any form of EQ or MSEB off, 3.5 SE plug, 40-60% volume, low gain and high gain.

================================================================================================================
Sound signature:

• The Tanchjim One falls in the same sound profile as the Tanchjim Zero, Ola, Ola Bass. It is a neutral-sounding set with a clean, punchy bass boost.

Lows

• This part is the most elevated in One’s sound. It is punchy, impactful, clean, with even amounts of sub bass and midbass in terms of elevation. Attack and decay is on the faster side, but never lacked on most genres. Despite its bass being boosted, bassheads on a budget may find this lacking, especially if you had bassy IEMs in your possession. It sure has more bass presence than the Tanchjim Zero though, adding a bit of thickness to its sound.

Mids

• As for the mids, it is well-placed and can sound forward at times. It does not have any midbass bleed to add a bit of warmth to the lower mids, making things clean and close to transparent as much as it can. Lower mids have an adequate depth. Upper mids are also well-placed with a good amount of clarity, air, and sparkle. There isn’t any form of unnatural peaks, harshness, or sibilance in this region.

Highs

• Moving on to the treble, it is well-extended but it lacks a bit of air to my liking. It isn’t rolled off or anything like that, but the cymbal crashes aren't as satisfying to my liking (personal preference). However, the detail retrieval here is still great and very commendable for its asking price.

Soundstage, Imaging, and separation

• The Tanchjim One managed to keep the Tanchjim Zero’s technical performance - it is above average for its asking price. However, the soundstage isn’t as wide compared to the Zero, but it is far from narrow or compressed. Separation and layering is really good for its price and has no problems rendering heavy passages. Imaging is precise and is able to render everything accurately, even when used on playing competitive games.

================================================================================================================
Other IEM comparisons!

• VS Tanchjim Zero
  
  • The Zero is a more neutral, sterile, thin sounding set. Both Zero and One are really good sets, and are more of a “different flavour” rather than an upgrade.The Zero is cleaner sound just by a hair bit, while the One is thicker in sound.

• VS KBEAR KW1
  
  • The KW1 is warmer in sound, and loses on the technical performance.

• VS Final E500
  
  • The Final E500 is a neutral sounding set, but is a bit mid forward compared to the One. It is a bit harder to drive as well. The One is thicker in sound and has more transparent mids when compared.

================================================================================================================
Pros:

• - “Relatively neutral” sound signature.
• - Very good balance of tonal and technical performance for its asking price.
• - Managed to keep the Tanchjim Zero’s positive qualities (subjective).
• - Chunky, impactful yet clean bass.
• - Open, transparent mids.
• - Decently extended, detailed treble.
• - Non-fatiguing upper frequencies.
• - Very good technical performance for its asking price.
• - Very good scaling capabilities!
• - Excellent fit, comfort, and isolation - even better than the previous Tanchjim Zero.
• - Very good, minimalist, sturdy build quality (subjective).
• - Excellent amount of packaging and accessories!
• - Fairly easy to drive.
• - Removable cable for a bullet-shaped IEM is quite rare!

Cons:

• - While being easy to drive, it needs at least 1.6vrms-2vrms dongle to sound the best.
• - Treble slightly lacks air to my lacking (subjective).
• - Soundstage may sound intimate to some (subjective).

================================================================================================================

Now that I have finished this review, I have realized that the Tanchjim “numbers” and Ola lineup seems to be the Tanchjim’s attempt to recreate the Etymotic lineup, in their own way. It does have the same sound profile, but it isn’t close when it comes to how “raw” the sound of Etymotic IEMs are. However, they managed to nail the nearly similar sound but with a better, ear-friendly fit, which makes me want to recommend the Tanchjim One to everyone who is looking for a comfortable, relatively neutral-sounding IEM aside from the Tanchjim Zero. I do find myself using it more often than my other daily IEMs. Highly recommended!

Pairing recommendation/s:

• - Source: This sounds just fine when plugged straight to a phone due to its easy to drive nature. However, using an external dongle or DAC wouldn’t hurt.

• - Eartips: The eartips are alright and enough for the most part. You may always use your preferred eartips.

• - Cable gets the job done and is sufficient for the most part. You may always use your preferred cable. However, its female pins are recessed so longer 2pin cables are most likely to fit well with this IEM.

IEM/Earbud/Setup configuration: stock large clear eartips, any form of EQ or MSEB off, 3.5 SE plug, 40-60% volume, low gain and high gain.

Additional Note here: I will be testing the Konoka with the stock configuration first (Music Mode), then compare it to the other configurations.

Sound signature:

• The CVJ Konoka follows the current CVJ house sound, wherein the pursuit for being a “budget all-rounder” sound is achieved. This is a fun-sounding, v-shaped set.

Lows:

• This is the highlight of the Konoka, coupled with its "quirks." In terms of attack and decay, the bass on the stock setup is raised, meaty, thick, somewhat rapid, and relatively clean for a cheap IEM. Switching to its "3D" modes, especially Movies and Esports modes, adds a little of "tactile vibration" to its bass nature, making the bass literally felt the more the Konoka sits flush in your ears. However, the tactile bass feature somehow only affects the midbass and not the subbass, exhibiting a “weird” character to it. It is punchy, can be felt, and will be perceived as “hollow”. However, these characteristics do not exist on the other two modes, so there’s that.

Mids:

• As for the mids, it is bassy, fairly clean for its price, and nothing to write home about. It is the mids that you would expect for its price in terms of quality. Lower mids are mildly recessed and show some minimal midbass bleed to keep things warm. Upper mids are elevated, bright, sparkly, clear, and airy. Regardless of what configuration you are with, the Konoka shows some sibilance or harshness in this region, creating a “strident” character, especially on sibilant prone tracks. This IEM is definitely not recommended for those people who have very sensitive ears.

Highs:

• Moving on to the treble, it is elevated, bright, with a very good amount of air. Instances of peaks and sibilance are still present in this region but it isn’t as prominent compared to its upper mids. Detail retrieval is average for its price and can pick up most details fairly easily.

Soundstage, Imaging, and separation:

• Average is the most fitting option to the Konoka in this category. It is properly done but nothing to write home about. Its soundstage is your usual wider than taller with decent depth. Separation and layering is alright for its price and suffers some slight congestion on heavily busy passages. Imaging is accurate and has no problems being used in competitive fps gaming.

Other switch configurations!

“Monitor” Mode

• The lows are a bit toned down and now more quicker, making the upper frequencies and its peaks more obvious. The overall sound is now cleaner though.

“3D movies” Mode

• This mode activates the vibrating driver, creating that “tactile” bass impression. Midbass are now more felt literally, punchier, but lacking in body. The mids also seem to recess more, and the upper frequencies are now brighter.

“3D games” Mode

• This seems to exhibit the same sound as what the 3D Movies mode has, but with less recessed mids and tamer upper frequencies.

================================================================================================================
Pros:

• All-rounder, fun sound signature.
• Well-tuned, smooth sound on stock configuration.
• “Tactile” bass response, literally!
• Fairly clean sound.
• Elevated, fairly thick lows.
• Substantially present mids.
• Bright upper frequencies (subjective).
• Average technical performance.
• Easy to drive.
• Versatile tuning switches.
• Very good fit, comfort, and isolation.

Cons:

• Instances of sibilance are present on sibilant prone tracks.
• The “vibrating bass” effect only works on certain configurations.
• The “vibrating bass” effect only affects the midbass, creating a somewhat hollow effect on the sound quality (subjective)

================================================================================================================

Despite exhibiting some “odd quirks” as a budget IEM, I truthfully enjoyed my test period with the CVJ Konoka. It is quite a unique experience for me to feel a mini-bass speaker/subwoofer attached in my ears. Without any gimmicks turned on, it actually is a well-tuned set and is very suitable to be an all-rounder IEM for daily usage, whether it be for gaming or for casual music listening sessions.

Pairing recommendation/s:

• Source: This sounds just fine when plugged straight to a phone, but is vastly better when used with a proper source. I suggest using a warm sounding DAC for this one to trim down some warmth.
• Eartips: The eartips are alright and enough for the most part, but using Final E-tips or any narrowbore eartips will help to tame down the sibilance and brightness.
• Cable gets the job done and is sufficient for the most part. You may always use your preferred cable.

================================================================================================================
Sound signature:

• Much like most Harman-tuned IEMs, the CCA Duo is a u-shaped, fun-sounding set. When paired with a neutral-sounding source, it may sound “neutral” to most ears.

Lows:

• The CCA Duo’s bass is clean, punchy and textured. Midbass and subbass quantity exhibits a good balance on this set. Attack and decay leans to the quicker side of the spectrum while sounding more than sufficient on most tracks, in a very good way. This is not a “basshead set” like what Legato is, but the overall character of the bass of the Duo will be sufficient on tracks, regardless of any genre.

Mids:

• Just like what the Harman Target aims, the mids here in this IEM are mildly recessed, but are open, clear and detailed. It will sound “thin” at times depending on the track. Lower mids are quite transparent in terms of thickness and texture with a slight midbass bleed enough to keep things slightly warm. Upper mids are definitely elevated, airy, sparkly, and clear. There are instances that peaks are apparent on sibilant prone tracks on this set. It is nowhere near fatiguing or annoying, but I do see those people with very sensitive ears might have a problem with the Duo.

Highs:

• The Duo exhibits a not-overly-bright, clear, and decently- extended treble without any signs of peaks, pierce, and harshness. Detail retrieval is above average as microdetails can be easily picked up, along with the macrodetails.

Soundstage, Imaging, and separation:

• The technical performance on this IEM is average to above average in my opinion. It isn’t the widest sounding IEM, but it never sounded cramped. It is wider than deep, with a good amount of height, width, and depth. Separation and layering are above average and will handle very busy passages easily. Imaging is precise, making it very suitable for live recordings and playing competitive games.

================================================================================================================
Other IEM comparisons!

VS Truthear Zero (Blue)

• The Zero has more bass quantity when compared, but is quite slow in terms of attack and decay. Its mids exhibit less warmth and texture when compared, with some instances of shout on its upper mids. Treble is a bit more extended on the Blue, but is quite unrefined to my ears. As for the technicalities, the Zero is a bit wider, while the Duo excels on the imaging and separation when compared.

VS Kiwi Ears Cadenza

• The Cadenza is miles better on the tonality due to its rich, lush, more cohesive, thick character It is also less extended on the treble area. It loses on the technical performance compared to the Duo though, except for its soundstage.

VS Simgot EW200

• The Simgot EW200 is definitely miles better in terms of overall sound. It is airier, cleaner and more precise in terms of sound compared to the Duo, but the Duo does not fall short in terms of its price to performance ratio.

================================================================================================================
Pros:

• A well-tuned, Harman-sounding IEM.
• Balances both technical and tonal performance quite well for its price.
• Fun, all-rounder sound.
• Clean, thick lows.
• Clear, open mids.
• Decently extended, sparkly treble.
• Average-above average technical performance.
• Excellent fit, comfort, and isolation.
• Very good build quality.
• Easy to drive.

Cons:

• Slight peaks are present on the upper mids on sibilant prone tracks.
• Minimal accessories for its asking price.
• Mids may sound thin at times.

================================================================================================================

The CCA Duo is a very recommendable set to everyone due to its all-rounder, fun sound while keeping the tonal and technical performance balanced in terms of quality. Despite exhibiting the same sound profile like most IEMs exist in today’s Chi-Fi market, CCA showed that they tuned the Duo well, making it to my top recommendations under 50USD. Well-done!

Pairing recommendation/s:

• Source: This sounds just fine when plugged straight to a phone, but is vastly better when used with a proper source. I suggest using a neutral sounding DAC for this one to trim down some warmth.
• Eartips: The eartips are alright and enough for the most part. You may always use your preferred eartips.
• Cable gets the job done and is sufficient for the most part. You may always use your preferred cable.

================================================================================================================
Sound signature:

• The KBEAR KB-KW1 sports a warm, v-shaped sound signature without any signs of fatigue or harshness throughout its sound. However, there is an obvious veil or “a blanket” type of presence in its overall frequencies, affecting the sound negatively, most of the time.

Lows:

• The lows are elevated, thick, and midbass focused. Attack and decay leans to the slower side, and will sometimes sound boomy. Midbass bleed is evident, making things muffled most of the time.

Mids:

• Mids are recessed, thick, smooth, lush, but suffers from veil, making things sound congested or nasal most of the time. This also in return hinders the detail and texture of this IEM . Upper frequencies are clear enough, but lack sparkle and air. No sibilance or any form of harshness are perceived in this region.

Highs:

• The highs are not that extended and will sound rolled off most of the time. It lacks air and sparkle. Details are average and not for critical listening.

Soundstage, Imaging, and separation:

• Due to the veil present in this IEM, the technicalities are also affected negatively. The soundstage is average in terms of width, height, and depth. Soundstage and layering are below average as the congestions are a bit apparent, and the imaging is accurate most of the time.

================================================================================================================
Pros:

• Fun, all rounder, warm sound signature.
• Chunky, elevated bass.
• Thick mids.
• Non-fatiguing upper frequencies.
• Excellent fit, build, and isolation.
• Lightweight, easy to use design and form factor!
• Clear mic quality!
• Very good fit and comfort!
• Very good amount of accessories!
• Very good design language (highly subjective)
• Fairly easy to drive.

Cons:

• The veil affects the overall sound quality of the IEM.
• Technicalities are below average for its asking price (due to veil)
• Mids are muffled and congested (due to veil)
• Treble is quite rolled off to my liking (subjective)
• Cable microphonics are apparent.

================================================================================================================

The KBEAR KW1 is one of the company’s newest products that goes within the “EDC” or everyday carry motif. During my real life, practical tests, they held up pretty well when used outside, particularly during commutes and calls-on-the-go. As for the hobbyist or “audiophile” side, this may not be the first option that you’ll be recommended with, but it is one of the options, that’s for sure!

Pairing recommendation/s:

• Source: Both products are more than fine with any smartphone, but the KW1 sounds better when paired with a neutral DAC.
• Eartips: Eartips are fine for the most part, but you may always use your preferred eartips.

IEM/Earbud/Setup configuration: stock medium clear eartips, any form of EQ or MSEB off, 3.5 SE plug, 40-60% volume, low gain and high gain.

================================================================================================================
Sound signature:

• The Kiwi Ears Cadenza is by far the best IEM under 50 USD in terms of tonal performance. “Neutral”, mild-u-shaped, “harman”, and “balanced” are the main descriptors of the Cadenza, and also lean to a slight warmish tone most of the time.

Lows:

• The bass on the Cadenza is mildly elevated, fairly controlled, and midbass focus. The bass here is nowhere near basshead levels, but is sufficient for most tracks. The decay leans to the average side in terms of attack and decay. There are times that the bass will sound monotonous and will lack texture, especially on bassy or basshead level tracks, creating a somewhat “soft” character to my hearing perception.

Mids:

• The mids are mildly recessed and are on the “natural” side in terms of position. There is a presence of midbass bleed here, making the lower mids warm and thicker than usual. Ed Sheeran and Sam Smith’s voices here are thick, smooth, and may lack texture at times in return. Upper mids are mildly elevated and exhibit a good amount of air, clarity, and sparkle. No abnormal harshness or peaks are present on this IEM during my tests, making it very recommendable for those people who have a set of upper frequency-sensitive ears.

Highs:

• As for the treble, it is “naturally” extended, has decent amount of air and sparkle. It never sounded rolled off nor too extended during my tests. Detail retrieval is average and retrieves most details in a track quite well.

Soundstage, Imaging, and separation:

• Technicalities is not the forte of the Kiwi Ears Cadenza. The soundstage is average in terms of depth and height, and wider than taller. Separation and layering is average to below average and it really shows when the tracks get busy. Imaging is average at best as it renders vocal and instrumental positioning decently.

• The Dolce edges out the Cadenza in the technicalities, but is less smoother and leans to a drier, brighter side of the spectrum. The Cadenza is also bassier as well.

VS KZ Krila (stock config)

• Both share the same sound signature, but the Krila is more technically competent. However, it is less warmer and suffers some metallic timbre, making things not smoother when compared to the Cadenza.

VS Celest Pandamon

• The Pandamon is a more balanced, thicker sounding set that also edges the Cadenza in the technicalities. The Cadenza is a bit airier in the treble department compared to the Pandamon.

VS Simgot EW200

• The Simgot EW200 is definitely better in the technicalities than the Cadenza and is on par in terms of timbre to the Cadenza when compared. The EW200 leans slightly to the brighter side of the spectrum and is miles airier when compared to the Cadenza.

================================================================================================================
Pros:

• Has the best tonal performance under 50USD I have tried.
• Non-fatiguing, smooth yet not too warm sound signature.
• “Natural” timbre.
• Mildly elevated smooth lows.
• Well-placed, open lush mids.
• Non-fatiguing upper frequencies.
• Average technical performance.
• Excellent fit, comfort, and isolation. Definitely one of the most comfortable ones!
• Visually-pleasing build quality (subjective).
• Easy to drive.
• Very good amount of eartips.

Cons:

• Bass may sound monotonous and may lack texture at times.
• Technicalities are nothing to write home about for its price.
• A case or a pouch would’ve been a great treat for everybody for its asking price (subjective).

The Kiwi Ears Cadenza sure is the best IEM in my book under 50 USD in terms of timbre! I really enjoyed using these daily during my test periods because it sounds really “rich” and “smooth” on most of my test tracks. Its smooth, musical character suits most of genres and everyday, casual listening. This will be one of my top recommendations if you are looking for the best budge IEM in terms of timbre! Well done Kiwi Ears!

Pairing recommendation/s:

• Source: This sounds just fine when plugged straight to a phone, but is vastly better when used with a proper source. I suggest using a neutral sounding DAC for this one to trim down some warmth.
• Eartips: The eartips are alright and enough for the most part. You may always use your preferred eartips.
• Cable gets the job done and is sufficient for the most part. You may always use your preferred cable.
