The package in Nicley decorated. inside is a large variety of tips a good cable and case.
The Quartet themselves are very rounded and are comfortable for long usage, I found the isolation excellent.

SOUND:
The Kiwi-Ears Quartet is a fun, warm sounding V-shaped IEM with a smooth detail and relaxed tuning that goes well with most music.

Bass: The lows on the Kiwi are prominent with the Mid-Bass just a little more so. Bass in general has good Texture, weight and speed. There is a little bleed into the lower mids.
It is sufficient enough to please most Bass loving audiophiles.

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

Treble: Presents with a good amount of air and a smooth relaxed extension. I found it to b enjoyable for most types of music without any harshness. This is perfect for treble sensitive listeners.

Soundstage: Is accurate and natural in size, it handles some busy recordings well and while not the most technical in nature I think gaming should work well.

Afterthoughts: The KiwiEars Quartet is a well-made and comfortable IEM, it is not a detail monster but rather a super fun and relaxed IEM, I think it appeals to the casual listener for its enjoyable signature. It's like the bigger brother to the Cadenza but just more of the good stuff.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

User Manual

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

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

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

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

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

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



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

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

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

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

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

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

The Fosi DS2
The DS2 dongle comes with a cable and adapter and manual.

The DS2 is very similar in sound to the DS1, it is lighter inn build but still made of metal and has dual outputs.
It performed very well in both full-sized headphone and sensitive IEM.
The sound is a slight warm but very transparent quality with an open and airy signature.
Impressions: The DS2 sounds clean, with good details, transparency and natural tonality with a hint or warmth and musicality making it very pleasant. In A to B testing, it provided a louder and better sounding presentation than the stock DAC chip included. It has a fair amount of air and openness, and soundstage is accurate and above average in width and depth. headphones tested with the DS2 were the HiFiman HE x-4, the Fostex T20rp, Dekoni Blues, 1More Triple and Philips X2HR to name a few, IEM use were the Moondrop Kato, Sonic Memory SM2, NF NM2 plus, the Kinera Hodur and Moondrop Aria SE.

The DS2 is an exceptional value in my opinion, it offers a noticeable improvement at a good price to performance ratio.

The Z2 features an LCP Dynamic Driver and comes in both a 3.5mm or USB-C fixed cable bullet style earphone.
It comes in a nicely decorated box, inside there are a number of different type and size tips and the default are very interesting cone shaped wide bore. it comes with a pouch and a silver foil cable.

Sound wise these are excellent. I wasn't expecting them to have good details and neutrality.
Bass is well controlled and slightly elevated from the neutral position.
Mids are clear forward and have a decent tone with minimal to no bass bleed.
Treble is responsive and controlled with enough sparkle and details.
Soundstage is moderate and accurate with it being wider than deep.

Sound;
Sub-Bass has more prominence than Mid-Bass, because of this there is very little bleed into the mids. The Bass in general is good but the KBear Little-Q and Dumpling produce a much better-quality bass.
Mids: are thin and forward but there's not too much energy there. Female vocals sound better than male.
Clarity and separation are good.
Treble: Is smooth and lackluster with a few peaks and a tiny bit of sparkle on top.
Soundstage: is open and wide, seems accurate for most uses.

Conclusion: This is a decent IEM but there are better options, although the cost is worth the tips and case perhaps.
Its not horrible it performs well just not up to the hype generated.

The packaging, accessories and cable are all typical for KZ, I would have liked one of their better flagship cables but this one does in a pinch.

Ergonomics are above average, and I found the comfortable with good isolation. The build quality is very good, and they look great too. This one has a resin back like the Standard PR1. I'll be judging this on the PR1 HiFi as I didn't have the pro or standard.

Sound quality and impressions:
Bass:
The Bass, lows on the PR2 are surprisingly nimble. this is planar bass done well. Both Mid and Sub have impact and texture with good depth and speed. Its detailed and almost Dynamic in presentation.
The Midrange:
Mids are rich but not over emphasized they are just perfectly focused; they have good body and texture to them.
The highs:
Treble has a nice airy and open sound with high details and a well-controlled extension, there is zero harshness on this part at normal volume.
Soundstage:
The staging is wide and deep with an accurate and detailed placement.

Afterthoughts:
The HBBxPR2 is one of those exceptions to the rules. Its a planar with planar Mids but has a more dynamic sounding bass. There is good resolution and details but it also very enjoyable and fun to listen to.

Sound:
The KBear Pecker presents with that classic fun V-shaped signature from a hybrid IEM.
The Bass is deep and Sub-Bass has a nice rumble, mid-Bass has a nice slam and texture but Bass in general is slow and a little thick.
Mids are warm and lush with a little recession and vocals placed sightly in your face but not shouty.
Treble is extended well with air and sparkle; it has smooth overall details.
Soundstage is below average with decent separation but not much else going here.

Conclusion: The KBEAR Pecker is a fun but not serious budget IEM that is a drop in the water of mediocrity.

Looking at the package you can tell this is a premium product.
Inside is a large number of accessories making the unboxing much more exciting.
I personally love the look and fit of these, and the cable is one of the best modular stock cables I've used.

Sound:
The IDUN Golden 2.0
The Bass is tight and fast with great control, it has presence but is far from emphasized.
Mids are well placed and have a nice warmish and organic tone. There are fine details and vocals sound rich and inviting.
Treble has excellent details and is open with a very good extension. There is both micro details and separation but just a little air.
Soundstage is slightly above average but not by much, it does have good accuracy and separation.

Conclusion:
The Kinera IDUN Golden is a well-tuned and beautiful IEM with its own unique charms, strengths and weaknesses.

Sound:
The VZ10 Bass is nibble and light, it is more a quality Bass than quantity. It is both neutral and detailed, with a good Mid-Bass punch.
Mids on the VZ10 are forward center and have a decent body but can be a little thin, they have a nice neutral quality and are never harsh. There is fine details in upper and lower Midrange but female vocals have a more pleasant tone.
Treble has a great extension and clarity. Its airy and well detailed with a slight sharpness but it's not too unforgiving.
Soundstage is equally wide as it is long and is deep, it's a natural field that works well. much detail and separation make it pretty good compared to others.

Afterthoughts:
The Joyodio VZ10, is an excellent choice for a good all-around non offence daily driver.

The box is typical and so is the cable unfortunately. While KZ has come a long way since that awful striped tangly mess of a cable that came with my ZST pro, I would have liked to see the Zar cable or JoyOdio cable come with the flagships. KZ for the most part have 4 basic tips, the White, The classic Starline, foam and those new spirally things. So, let's talk about the build quality, this is a solid design. There is excellent isolation and while they are big, they fit me comfortable. The look is a cool 3D design and I do like that.

Sound:
The Bass on the AS24 is neutral/ Balanced to boosted just a little, it has good speed in both Sub and Mid and excellent details. It works well with speed metal, Jazz and EDM.
The Midrange is balanced with good body and separation. Vocals are forward and clear as bass bleeds very little.
The Treble is open and airy with rich details and just enough sparkle and extension.

The DZ4 is a truly unique configuration. The packaging is beautifully simple. Inside is all the great accessories included. The DZ4 themselves are light and comfortable. They are a sturdy 3D printed shell and I really like the look as well. The case is very sturdy but on the smaller side, still it works good enough. The cable is both pretty and well made, it also comes with tips of good quality.

Sound:
Bass: presents neutral with a little Sub-Bass boost but tastefully so. Bass in general is more quality than Basshead. The speed and details are excellent but is a little less in texture than the average Harman.

Mids: midrange shows off the DZ4s neutral tuning mids sound fantastic and have a nice natural sound with plenty of energy and details. vocals are forward and female vocals sound a little better in my opinion.

Treble: The highs have air and sparkle without harshness and over extension, good energy and details in general things sound crisp.

Soundstage: Is accurate and open but the Width is much more impressive than depth. Still, it doesn't suffer on busy recordings.

Afterthoughts: The DZ4 offers an exceptional value for someone looking for a neutral IEM with good quality Bass, Mids, Stage and non-offensive treble.

Packaged in the typical KZ/CCA packaging simple and sturdy is the less than simple CCA Duo a dual dynamic IEM with two 7mm Dynamic Drivers, with dual magnet arrays, and dual cavities each shell.
I found them to be comfortable and they provided good isolation.

Sound:

Bass:
Thew CCA Duo presents with well controlled and very clear Bass, lows are present and have depth but are more of a quality Bass than a thunderous impact. Texture is good but Bass in general is neutral, fast and detailed.
Mids:
The Midrange is very well detailed with a forward center position. Vocals sound a little in front of the instruments and thinner and colder than I was expecting. Still, it has a refreshing charm that shines with female vocals.
Treble:
The highs are surprisingly airy and smooth with a nice fine details and good separation.
Soundstage ETC:
The soundstage is open and has a decent width, depth and height in equal proportion. There is fairly accurate imaging.

Conclusion: The CCA Duo is a refreshing new tunning from the company and a few fine tunings, and it could be amazing. If you are into a more neutral kind of Bass, this might be interesting.
