100+ Head-Fier
Pros: Great bass, sexy wood design, pleasant fatigue-free signature
Cons: Tangling cable, some lack of treble, small L/R marks
Shozy has kindly provided me a review unit in exchange for the honest opinion. They are in active use for about 6 months.

I should first note that my experience with IEM is a bit limited by now, so the nuances I mention should be taken with a grain of salt. It would be great for you to read other reviews as well should you consider getting a pair for yourself.
35 y.o, an avid music lover since 18-20. Mainly listening to jazz, soul, funk, and also love disco, reggae, afrobeat, new wave, some trip hop and electronica and a bit of classical (hard rock and metal genres are a bit out of my music world, so I may not be the best adviser). Also love to hear vinyl should I have a chance, but mainly use digital lossless files for convenience and portability.

I prefer not too bright, fatigue-free sound without too much harshess (maybe a bit dark, but not veiled and without losing much in resolution). Sony MA900 is my favourite open-back model for home use, but IEMs became my most used way of listening both in office and on the go (which happens on a daily basis). That is why fit, convenience and ease of use along with reasonable isolation do mean a lot to me along with the sound quality.
Now let’s talk about Shozy Zero.

Build quality and comfort

The set of accessories is not really outstanding: Zero comes with three pairs of silicone tips of different size. Practically it is enough, although there are budget models nowadays with the richer packages which can futureproof your spendings. What’s much more impressive is the quality of wood in drivers, jack and chin slider: it does look really tasteful and you get the whole aesthetics while holding these IEMs in your hands.

Cable is quite soft but feels durable at the same time. The only drawback is that it tangles quite easily no matter if you store earphones in case, backpack or simply in your pockets, and it often takes some time to untangle. As for the jack, it looks sturdy and seems like a gold-plated one (so, the quality is high indeed). L/R markers, however, are very small (my review unit comes with slightly different wood color on each side, but I’m not sure if it’s the same in your case).

These IEMs are quite compact, so fitting them into my ears does not cause any issues. Wearing them cable down I do perceive some microphonics, however, an over-ear way completely eliminates the problem. Please, also note that on my unit the eartips may occasionally get loose from the driver, so please take some care while taking IEMs out of ears since otherwise you may simply lose a tip.

Isolation is fine, especially for a dynamic driver model. Not sure about the subway, but on the street it feels sufficient especially with music turned on. You can still hear a signal from auto, loud noise or very loud voices. I guess the amount can be lowered further after playing with tips, however, I prefer to hear something from the outside world and did not aim to achieve a total seal.


I am not a pro in measurements, but Zero does seems a bit dark and smooth in overall tonality (be it a but V, W or even L-shaped based on various descriptions). Still, all frequencies are well-present and not much lack of either mids, highs or deep bass is perceived. Personally, I chose a seal which is not too deep since there is a bit more low frequencies in this case (not affecting other ranges of spectrum), but YMMV.

Bass is really the star of the show here. It reaches deep into the subbass regions but still remains detailed and well-controlled. It’s very tight and resolving (especially on well-mastered recordings) and, from memory, never turned boomy even on hip-hop tracks.

Mids are just slightly rolled off from bass, but vocal, guitars and other midrange instruments are well-defined and don’t sound veiled. Timbres are natural and instument separation is quite fine may it not reach the BA level of resolution.

Treble is slightly rolled off being very comfortable and non-sibilant or harsh. High-hats are well heard and detailed too, while some may look for more accentuated highs and Zero is not really for treble-heads.

In general, on all sources Zero shows a bit dark tonality. The sound feels quite solid and not hyper-detailed, with fine resolution and instrument separation. Non-tiring, fatigue-free listening with Zero is great for long sessions.

Nuances, comparison and compatibility

Shozy Zero’s sound signature significantly depends on tip selection. I tried Sony Hybrids and to me they provide a bit less subbass but also more clear mids and highs (maybe because of a slightly better ft). General tonality remains the same, and otherwise perception of changes is quite subjective and probably depends on ear shape and size (mine are more or less average).

Even more important is how these IEMs grow with the source,

They provide a good synergy with iBasso DX50 where bass of Zero compensates its lightness in DAP itself, while other frequences are quite fine.

With Hidizs AP100 (modded ver. MM2 with a bit more dark tonality in comparison with stock) lows are better defined and more punchy, and the resolution of theble is significantly better, so to my tastes it’s a definite step up.

A great level of details is heard together with HRT microStreamer. The tonality is more neutral and very musical, although the subbass is even more dynamic and resolving.

I also tried to use Meier Corda Rock amplifier, however to my surprise mids (especially upper regions) became much more fatiguing and I did not listen this combo for too long. So, overall, it’s all about the synergy!

I have compared Shozy with the single balanced armature model, Etymotic HF2. They are two very different earphones and do show a typical nature of both driver types. Bass of HF2 is less “bodily” (while still perceived well), but mids and treble are more detailed. So it’s more or less a matter of mood and taste, while both sound good with AP100 (HF2 is also a bit dark and warm with this source, to my surprise).

Speaking of ergonomics. Etymotic’s cable tangles much less, but the seal is deeper which for me turned out quite tricky since the sound of BAs is much more fit-dependant. It was less convenient to use them on the go, and Shozy’s insertion is much simpler (while YMMV, of course). As for other dynamic models, I’d like to refer you to @HiFiChris’s review where he performs a great and detailed comparison.

Future plans

From what I’ve read, I think of trying Oriveti Primacy, LZ A4, Lear LHF-AE1d, MusicMaker TK12/13 and Blue Ever Blue 1200EX as various upgrade options. They’re all so different that it’s a good idea to try as many as possible not forgetting about the music itself as the main thing.

Zero is indeed musical and I’m truly happy to own it as a first serious IEM at my disposal. The form factor itself was a pleasant surprise since I did not expect such a full sound from an earphone and the isolation turned out superior to all on-ear models which I used before for outdoor listening.

Blue ever Blue 1200EX are an excellent choice if you like single dynamic drivers!
thanks for the great review!
@peter123 thanks, you were one of the first to point me to Shozy :)
@drbluenewmexico yep, I am really curiolus to hear 1200EX
dope work! thanx! 
Pros: Well made, good sound and overall balance that works with a variety of genres. A lack of harshness or distortion at moderate levels. Price.
Cons: Rubbery cable gets tangled easily and is a bit noisy. Not so great at louder volumes.
Some time ago I received a package in the mail inside of which was a small bag with a pair of IEMs and a note to burn them in for 100 hours with orchestral music. The IEMs turned out to have come from Charles at Shozy (and Cozoy), the maker of the Alien DAP.  Very small with wood and metal housings and in-built cable (which uses high-quality wire according to Charles from Shozy) their only negative is the rubbery outer sheath of the cable which makes it tangle easily and transmits a bit of noise.
The first time I listened to them, knowing nothing about them, I was very pleasantly surprised at the good, and fairly evenly-balanced sound, and general lack of any unpleasantness. After burn-in, the sound is more on the warm side of things with a noticeably stronger bass presence, but it keeps its sweet treble and good mids, making them, in my opinion, excellent all-rounders, and worth pairing with a good DAP. One of the best things about them is that the stock tips work perfectly with them. I tried switching in my usual alternatives -- Spinfits and JVC Spiral Dots, but each messed up the nicely balanced sound. The only sonic negative I could find was that they aren't so pleasant to listen with at louder volumes.
Overall, this has put them way above any pair of $50 IEMs I've tried (excepting the Meze 11 Neo) and made them good enough to slip them into a pocket for daily carry duty.

Pros: Easy on ears sound signature, has good mids. Comfortable. Looks beautiful.
Cons: Has mid bass problems, Lacks top end extension and micro detailing, sounds grainy.
 Shozy, A brand that hails from HongKong, going strong since 2012, better known for their amplifiers, DAPs and DACs has the mighty popular Shozy Alien that looks, sounds and performs outstandingly when it comes to SQ and details. They have plenty of outstanding products and are extending their range with new products ever now and then.
 What I have with me here is their Latest product, their maiden go at In-ear earphones Shozy Zero which ships worldwide is priced $60 comes in a single color scheme, not exactly color but has only one variant. Made out of selected high density Brazilian rosewood chambers and comes with selected cables.
 Some of its features are high efficiency drivers with low impedance, flat frequency response with good extension, low distortion without early roll off.
 It remains to be seen how this turn out in real life though.
 At $60 it has plenty of competition at its hands from Vsonic VSD3/2, Soundmagic E50, Brainwavz S3, Rockjaws Alfa genus, Vivo XE-800 and even the legendary Hfiman RE-400!! I will compare it with RE-400, Alfa genus and Brainwavz S3.
 Lets find out how this wooden beauty performs.
 Before that I would like to thank Ken from Shozy for this sample unit.
 If you want one you can get your from these links.
 Shozy Zero comes with minimal accessories, Nothing fancy at all. You can find 3 pair of rubber tips, a carry pouch and user manual. Its nothing I will complain about buy they should have included a cable clip, doesn’t matter how selected the cable is, it has microphonics and a cable clip will help in keeping it low.
 Don’t expect much from me as mine came with just the earphone and tips. No retail package so I cant show you that.
 Build quality is nice, straight barrel design is nothing one can complain about. Rosewood looks really nice, there is some stress reliving at the earpiece end and it does its job, sadly there isnt much at the 3.5mm jack, just tiny bit to protect it from sharp bends. Y splitter has minimal profile and has no stress relievers at all. There is a vent, oh no its not on the outer side, its at the bottom of the nozzle, yup, that’s a vent. R/T markings are on the stress relievers.
 Cable might have something special inside but to me it looks like just like the ones we see with KZ earphones. It has some microphonics for sure but not excessive, its bouncy and doesn’t exactly look strong but I have used it under stress and it hold up fine. Lacks a cable slider.
 Isolation is average and acceptable.
 I like the use of wood, it looks good but not as good as Dzat DF-10, which looks fantastic.
 This earphone comes from an exceptionally potential brand that has delivered one of the best Hi-res player so it's obvious to have hopes high.
 On first listen its quite good, I burned it for more than 150 hrs and used it mostly every day before I go to bed. It sounds perfect without amping and a mobile phone will drive it nicely.
 Signature is warm, bright and slightly splashy, not as bright as HA2 though.
 I am using stock Rubber tips for this review, which have really wide bore. It sound better with foam and narrow bore tips, try it if you have some lying around, it helps in smoothening things out.
 Lets start with our basics.
 I have to say, Zero responds well to EQ, Try yours.
 It's not exactly balanced, doesn’t take off like a Wooduo neither stays calm like HA2, does its job and keeps calm when not summoned upon.
Bass quality is above average, it has nice thump, good amount of air and can reach deep too. It has nice impact but its more soft than hard. Thanks to the wooden chambers Zero sounds really meaty, organic and natural. The only problem I have with this earphone is that it has some mid bass hump which gets bothersome once you come across some mid bassy songs, it takes the center stage and somewhat overshadows sub bass to an extent, and this mid bass hampers decay too, which is good by all means could have been better.
 Bass has good amount of details for an $60 earphone, control could have been better, not bad by any means, better than Brainwavz S0 and Soundmagic E50 for sure but can't be compared with RE-400.
 Notes do lack some depth, no bleeding what so ever.
 I have seen better, but not from a dynamic driver earphone in this price range, Meelec A1512nd gen is a totally different story.
 I am a fan of beautiful mid range presentations, and as far as I am concerned Shozy Zero has some of the best mid range you will find in an earphone for around $50. There are many earphones which sound better overall but zero has really nice clarity and forwardness which I really appreciate. It has good details and nice transparency.
 Both male and female vocals sound good, meaty, organic and full bodied, thanks to shallower notes depth male vocals sound thick and sharpness with female vocals make them enjoyable, nicely tuned I must say. Upper mid range has some humps which makes some instruments like cymbals and guitars shine a bit more than others.
 Zero has good transparency, imaging, presentation, doesn’t lack much precision and clarity but texture is lacking, it sounds grainy, not as smooth as one would expect, it maybe the housing but what matters in the end is the final output.
 Has a nicely spacious stage, not exactly RE-400 spacious, but spacious.
 I might have sounded harsh, but all in all this mid range is far superior than S0. E50 and will even surpass 151 2nd gen if you don’t like sharper notes presentation.
 Zero has, I have to say good still not so good highs. It has good energy, good amount of details, better than average separation and transparency, nice sharpness, doesn’t sound harsh but at the same time it lacks the extension I was looking for, its good, but there are some dips and few peaks that make things worse.
 Even though it lacks extension, treble on this is neither over done nor rounded off. It sounds cohesive and engaging, doesn’t put anything off, but those peaks with upper mids can be bothersome to some, especially those who are treble intolerant or like it smoother.
 VS Brainwavz S3 :-  S3 sounds cleaner, has better clarity, transparency, better bass with deeper reach, no mid bass hump, far better decay, smoother texture devoid of any kind of graininess, better top end extension, devoid of any kind of harshness. Comes with plenty of accessories. Sounds louder, has bigger stage and sonically superior.
 Zero has better balance, everything sounds meatier and more natural with awesome timber, notes are thicker too. Has less microphonic cable.
 S3 wins Hands down.
Vs RE-400:- Has better sub bass, better extension, faster decay, no mid bass hump. Has better clarity, transparency, details, sound stage and sonicality. Lower microphonics. Better accessories. Has reported durability issues.
 Zero has better cable and build, has more bass.
 Technically RE-400 is a far superior earphone.
Vs Alfa Genus (Black Nozzle):- Alfa genus has far more attack when it comes to bass energy, has bigger and stronger slam. Vocals have better texture and highs are smoother, has better sonicality. Has far better cables, build quality is awesome.
 Zero has better clarity, transparency and details. Everything sounds more natural and organic. Has better decay and top end energy too.
 Shozy all the way unless you want bass.
 Shozy Zero is a perfectly nice sounding earphone with good sound quality, nice timber, good tonality and nice build quality, let down by some mid bass hump and slight graininess.
 If you are looking for an earphone that has natural timber, meaty and warm sound signature, thicker notes with good clarity and transparency, you should consider the Shozy Zero.
 Thanks for reading guys, cheers. Have fun, enjoy.

Nice review, mate! 


Headphoneus Supremus
Pros: Great detail retrieval, Excellent speed and control, above average soundstage, Clear sound, Very good dynamics, Good Build Quality.
Cons: Not so good strain relief above the 3.5 mm jack, present mid bass, overshadowed upper treble.
After giving the Shozy Zero a good listen for a few months and switching to better sources. I finally got the proper analysis. Thanks NLNH and Shozy for the Shozy Zero. This analysis will be short because it's to keep the reader's attention. My previous reviews were too long winded. So let's get down to specifications.

Sensitivity(at 1Khz) 94db

Frequency Response 20hz-18khz

Input connector :3.5mm (1/8 inch gold-plated stereo TRS plug)

The Shozy Zero also comes with 3 Sets of eartips (S/M/L). A rectangle hard clam case. Also a User Manual showing a frequency chart sweep of the Shozy Zero.

Fit: I used the double flange ear tips that came with the Shozy Zero and it was a perfect match. Excellent comfort and for long duration listening.

Build Quality: Considering that it's made out of wood. You'd expect the durability is expected to be far greater than the typical ABS housing of other IEMs? Right? That is correct. The Wooden earphones of the Shozy Zero feels thicker than the typical ABS earphones. Although I wouldn't recommend tossing these around because they are still made out of wood. It is also advised on the User manual to avoid using this in humid weather so the Shozy Zero will not be damaged. Considering that I got the Shozy Zero in the summer. It was unavoidable. However. The Shozy Zero remained unscathed. The dewpoints that I dealt with all summer were typical for tropical areas (Despite being in New York). Anyway. The cable is thick and springy. The springy cable doesn't really bother me. What bothers me is the short and stubby strain relief above the Shozy engraved Wooden jack. It concerns me. The strain reliefs below the Wooden earphones are thick and inspire longevity. Due to the fact that it's rubbery and stiff.

Onward to the sound.

Source used: ZTE Axon 7 w/Poweramp Alpha Build 703. Headset Hi-Fi Mode on Super.

How does one describe the Shozy Zero. Three words. Organic. Smooth. Warm.

The sound of the Shozy Zero is quite simple and straight forward.

Let's start with the bass.

BASS: For $50. The Bass is quite textured and deep. It seems that it can reach the subbass territory. Will this please bassheads? Probably. Most likely more likely for those who are into Drums and Bass and Trance. It has deep Bass, but it also has some mid bass. As a result the sound is warmer. The bass control is also quite good. It's quick and punchy like a Professional Boxer. There’s practically no Bass bleed. That leads me to talk about the mid-range.

MID-RANGE: This is pretty interesting. Not as good as my Titan 1 (it's close by about 25%), but far better than my retired M-DUO. The detail retrieval is quite good for $60. The strong Bass is helping the mid range become thickened and smooth. Like a delicious cake mix being made for a birthday. This results in a tasty and savory performance of many flavors and for many flavors. Such as Pop, RnB, Hip Hop and Drums n Bass. Another aspect I should mention is the clear vocals. Whenever I listen to Epica's music, I can hear the clear vocals. Clear yet not too forward or too recessed. It's just right. I can actually hear the choir and the lead singer without having to stress my ears. That's good stuff.

TREBLE: It's clearly present due to a bump in the frequency in the upper Mids and lower treble. Although it's not insufferable like the M-DUO. It's softer and more graceful and packed with plenty of detail for a $50 IEM. When I listen to Metal, Classical or Orchestral music. I hear the strumming of strings quite clear. Not TOTL clear, but clear enough that you don't have to focus on trying to hear it. I noticed that that the Shozy Zero does particularly well with Epica’s music. Which is a combination of Metal and Orchestral music. The guitars are like super crunchy and very detailed. It usually puts a smile on my face. The upper treble is there, but somewhat overshadowed by the lower treble.Now onward to the Soundstage/Dynamics.

Soundstage/Dynamics: Now for this part I used a soundtrack that still impresses me bit in this department. I used Evan King's MDK - Shinespark. I was just flat out impressed what this $50 IEM was capable of. You could feel the spaces in between the instruments while maintaining an above average soundstage. Quite impressive. The spaces were still quite small. Yet it was still good. BTW, the soundstage is 3D. Not 360 3D. Mainly because I don't have any true binaural recordings.

Conclusion: After a few months. I have become more attached to the Shozy Zero. It just fits my preference of a more musical experience. The Shozy Zero just does everything right for a $50. If you are into a wholesome warm and musical experience and never owned a wooden IEM and curious about it. Then the Shozy Zero is for you. Otherwise, analytical lovers won't like these. The Shozy Zero is practically the complete opposite.
I agree with your take on the Zero - quite a bargain for $50.  I use it often when I don't want to go out with my more expensive IEMS and I find it totally satisfactory and enjoyable.
I love this IEM. It's accurate and balanced.

Reviewer: AudiophileHeaven
Pros: Soundstage!, Mids, Bass, Accessories - especially the carry case, Cables, Wood housing, Smooth & Dark sound, Isolation.
Cons: Rolled off treble, slightly rolled off bass, driver flex.

My name is George and I'm one a big music fan! I sometimes carry an amp stack to listen to music, even if using IEMs

We use OGG -q10 on almost everything audio related to the games we're creating on

I like bright sounds, clear sounds, lots of treble and bass, and I listen mostly to upbeat music, except for a few select masterpieces - like most of the songs made by Jill Tracy.

I've been using ShozyZero for a while now, then my brother was really looking into them, so I gave them to him. He's been really happy with them since he got them so yeah...

This review will also include real world usage notes and what to expect with heavy usage, travel and after abusing ShozyZero.


Words before we go in depth

Before we even begin this review, please understand that the price area of 50 - 250$ is very crowded with literally hundreds of IEMs from many producers and many different signatures, so nobody will be able to pinpoint a best IEM, but best from the tested ones, or best at something, or best for a personal preference. In these conditions, this review will describe the sound as it is - with most personal preferences noted separately.

Equipment used in this test

- Fiio X5ii
- Oppo Ha2
- Fiio X1ii
- HTC 820
- Xiaomi mi max Hydrogen
- Sennheiser ie800
- Ultrasone dj one pro
- SanDisk Clip+
- Probably should stop here, but there are a few others I used when testing ShozyZero.


- Box
- Short manual
- 3 pair of rubber tips,
- One of the nicest carry boxes for IEMs at this price range.

After 1 month of usage: Carry box held to usage. It has been dropped a few times, even on public concrete floors, still looks ok.




While the cables are ever so slightly microphonic, my listening was done while sitting in front of a computer. On the bright side, the cables are long enough so they don't pull the IEMs out of ears, they allow for over the ear wearing, and the cables are flexible (if not a little springy if I may add).


The cables did not get tangled while the IEMs were thrown around, and don't seem to have shape memory.


It's pretty good. While music is playing at a moderate level, most outside noises are drowned out, but stronger sounds are still audible. Music doesn't escape from them, so ShozyZero are good to listen to in a silent place.


Wood + rubber all around. While it has a certain novelty to it, the wood does it's job fairly well.

At first, I expected the wood housing to provide a strange feeling or sound, but it's proven to be a fair housing for IEMs. I personally prefer metal or ceramic for IEM housings, but my brother likes the wood both in feeling to the touch and sound.


Good, with the mention of some driver flex. While this is not a deal breaker for most people, I prefer no driver flex.

Note: My brother doesn't seem to care much about driver flex, nor to notice it, so not everyone is affected by driver flex.



Bass is thick, slightly rolled off at the low end, and while it has a great presence, it never feels slow nor sleazy. One thing that can be said about the bass is that it keeps up with the pace while sounding natural. The signature is certainly warm, but the bass has a normal decay.

[Short story]: It is there, thick, doesn't overtake any other frequency.


Mids are sweet. They sound sweet, are emphasized, the signature being slightly rolled off at low end and rolled off at top end (so we can say that the signature is mid-centric to begin with). Shozy is honest and brings this feature upfront in their advertising. While this signature won't please everyone, listening to guitars surely is a treat and voices are right on spot.
If mids were to be described they would come off as very clear, detailed, and having a specific sweet sound to them.

[Short story]: Mids are the center of Shozy Zero's sound, very clear, good details and an interesting tonality that's dark, warm, but clear.


Treble is rolled off. Compared to my tastes and listening habits, treble relaxed but it is rolled off.

Now this is both a good and a bad thing, depending on whom you ask. While I need treble to strike with true brightness, my brother likes this smooth signature.
Best way to put treble is that it's a like it or break it thing. It is not for treble heads. Don't get me wrong, we can easily hear cymbal crashes, but they are so very smooth. Adding treble via EQ alleviates the situation, but they won't become bright regardless of adjustments.


Soundstage is a very strong point of ShozyZero! It insantly hits the listener how all sounds can come from different parts of space. For a IEM this small, soundstage is huge, comparable to open back headphones. Bass notes can be heard coming from exact areas in around of the listener, instead of being present in the entire audio space.
It is probably related to the wood housings, but soundstage is one of the very strong points of Shozy Zero.


Source synnergy

ShozyZero sounds pretty good out of my phones (HTC 820 or Mi max). They are not very source dependent, so if you want to buy a ShozyZero and listen to them using a smartphone - it's a pretty good idea. Fiio X5ii surely made the sound better for them, and allowed for a much better EQ than my phones, but the sound directly out of the phone was not disastrous. ShozyZero is pretty sensitive, so most sources will be able to drive them well.

Hiss or other problems

No hiss or other problems were detected, but the signature is forgiving by itself. The forgiveness of the signature can be noted as a problem since I personally want a very bright, revealing and tight sound.

Closing words

ShozyZero sure is an interesting IEM, with a fun sound, that will appear to some. It's very clear, has a good bass, has a warm - darkish mid centric signature with an unexpected large soundstage, especially for it's price.

To describe my experience with them: After receiving ShozyZero, I allowed myself a pause from driving of about 15-25 minutes where I was really intrigued by the sound, especially the soundstage. They need EQ to work well, and Fiio X5ii came in and has really helped ShozyZero sound more to my liking, but I was able to watch a few music videos straight out of my phone and the sound was still clear and detailed, ergo without the treble and the jump in resolution that x5ii brings compared to phones sound.

[Disclaimer : The test unit was provided by Shozy, but the opinions were not affected in any way by any party except for the mood in the moment of writing this review. All impressions are based on one set of ears and one musical preference, so they should be taken with a grain of salt. Comparison with other IEMs or headphones felt unfair as most other IEMs tested or that took part in the test are not in the price class and have a radically different signature.]

SHOZY Zero IEMs Review - Expatinjapan

 Head Pie  
SHOZY Zero IEMs review​
 - expatinjapan​
It was pleasant to receive a set of beta SHOZY Zero IEMs in the post recently. I love wooden headphones and earphones. They have a natural, organic, smooth and lush sound. 
I was not disappointed by the SHOZY Zero they seemed to tick all the right boxes straight off the bat.
The construction is very simple, nothing too complicated about how they are put together. 
Simple is best, less is more and other adages to explain this concept.
The SHOZY Zero is made of (edit) ??? Wood nice and solid.
The size is great and would suit any ear canal size with the right tips.
No chin slider for fans of the old chin sliders.
Wood everywhere, even the cable seems to look like its made of wood. ​
The groove is an air pressure regulator.​
The SHOZY Zero is an easy fit.
They can be worn hanging down or over the ear, I myself prefer over the ear usually as I can get a good seal and also lock the IEM in place.
Very comfortable for extended periods of time.


The sound is well matched with the SHOZY Alien DAP and no
doubt they had a close relationship when it came to tuning these Zero IEMs.

Like the Alien DAP the sound is smooth, organic and accurate.

The SHOZY Zero is fairly flat, it does not seem to overly favor the lows, mids or the highs.

It scales up well with more volume whilst losing no accuracy and creating no distortion.
The Zero has a fast response, great separation, good width and lots of height.
Instrument separation and layering is wonderful.

The vocals are well matched to the music and are neither forward or recessed, but just right where I like them - with the music.

The SHOZY Zero reproduces the original recordings with an accuracy that belies their asking price.
SHOZY Zero frequency response.​

The SHOZY Zero is priced at US$50. A reasonable price for the IEMs. They could be priced a bit higher and still be acceptable.
It`s the kind of IEM I would feel happy buying a friend for a gift, smooth, well layered, good width and height, detailed and also lush; not to mention comfortable to wear.


The SHOZY Zero is a bargain IEM in terms of its price and performance.
Very smooth and silky, well balanced between the lows, mids and highs make this a pleasure to listen to.
It scales up well with more volume losing no accuracy and creating no distortion.
The Zero has a fast response, great separation, good width and lots of height.
Instrument separation and layering is wonderful.

It is an IEM I could listen to with pleasure for extended periods of time, laid back but without settling for less in the separation, detail, layering departments, decent width and height make this $50 IEM a possibly popular choice in the coming months after its release.
Thank you to SHOZY for sending the ZERO (beta) to Head Pie for review​

100+ Head-Fier
Pros: Analog Sounding, Rich Mid-range, Solid Mid-bass, Coherent and Precise Soundstage
Cons: Recessed Highs,Lacking some Sub-bass Decay. Strain reliefs do not feel adequate, Springy Cables
Before I start this review, I would like to reiterate that we all have different experiences when it comes to using earphones/headphones. YMMV and this is merely my "subjective opinion". I hope that helps and if there are any disagreements, feel free to comment :). I'm all ears! 
Some history behind Shozy:
Shozy is a brand from Hong kong that is relatively known amongst the "audio enthusiast" community for releasing the odd looking "Shozy Alien". Recently, the brand decided to release several IEM's to penetrate the already crowded "budget IEM' market. I didn't show much interest initially, until I saw the gorgeous Shozy Zero. I'm rather fond of "wooden housings" (my ZMF Vibro Mk2's are a testament to that statement). The CNC finished nozzles and resonance chamber housed driver sounded rather ambitious, considering that this is Shozy's first IEM offering. Most importantly, they only cost 59 SGD. The attractive price called out to me. 
The Shozy Alien in Gold
As you guys know, I am an avid believer in single-driver configurations. I tend to apply a reductionist-objectivist view with IEM's. "Less is more" and damping/material design is the best way to achieve any given sound signature. The Shozy Zero fits that bill and I decided to purchase them from Null Audio. Do take note that I am in no way affiliated with Shozy or Null Audio
Special thanks to Null Audio for the speedy delivery of my IEM's.
Package and Accessories:
[size=xx-small]Taken from a Japanese Forum[/size]​
The package was rather sparse. The box's design is non-descript, with some of the Shozy Zero's features printed at the back. Upon opening, we have:
1 X Shozy Large Pouch
1 X Shozy Zero IEM
1 X Frequency Chart/Measurements
1 X S, M, L Eartips
I am pleased to say that the overall package is rather cohesive. There is enough provided to get started with your IEM's. The Shozy Pouch has an embossed "Shozy" logo on the top. Its clam-shell design is rigid yet flexible, providing ample protection for your IEM's. Do take note that the case is a tad too large (considering the IEM's have a slim, negative profile). The extra space allowed me to fit in a couple more accessories (My Cowon Plenue D fits snugly inside). 
I have to commend Shozy for including the frequency chart print-out. This is unheard of with most audio companies and it serves as a "convenient extra", saving us the trouble of visiting the website for the measurements. I welcome this change and I hope competitors could be as transparent as Shozy.
Overall, the accessories and it's offerings are well thought out and I have no qualms about them. 
Build Quality:
Right out of the box, the Zero's feel solid and robust. The  shells are beautifully finished, with some minor imperfections (characteristic of the wood used) such as discoloration. Aesthetically, the earphones look exotic. The rosewood chinslider is easy manageable, with a taut firmness when adjusted. The engraved "Zero" logo on the Y-split and jack-end are nice subtle touches. The fitment of the Zero's is incredible. The nozzle length is adequate and fits snugly in my ears with the medium tips. The IEM's are comparatively tiny to many of its competitors, with an almost negative profile. Isolation is decent, blocking out at least 80 percent off outside noise (YMMV) 
However, the springy cable sheathing is oddly "sticky" and clumpy feeling. It tends to spring out into a mess when rolled up nicely. The strain reliefs on the driver housing and jack end doesn't exactly inspire confidence. The strain reliefs feel a tad too soft, with a lack of "length" to offset the weight of the cable to the reliefs.

My Selected Playlist:
Plastic Love by Takeuchi Mariya (Imaging/Soundstage Test)
Songs for Judee by Case/Lang/Veirs (Female Vocals)
No Fun by The Stooges (Fatigue Test)
Downtown by Destroyer (Vocal Positioning Test)
From the get go, my first impressions of the Zero's are "Lush, Mid-Centric and Recessed". The liquid mids are smooth and supple. The highs are somewhat muted, with a tinge of sub-bass and speedy mid-bass punch. These are not "bass-monsters" and I wouldn't recommend these to bass-heads. I burned them in for approximately 20 hours through regular usage (had a holiday in Chiang Mai). The treble was noticeably clearer with an added "rigidity". The Zero's have an impedance of 32 ohms. The low input impedance is easily driven from any portable source. 

Imaging/Soundstage Test: This J-pop (lollita) track sounds mellow, rich and spatious. The highs from the wind instruments and keyboards are rather muted, but the forward presence of the mids captures the timbre of the aforementioned instruments beautifully. As mentioned in my previous reviews, IEM's aren't exactly known for their immaculate soundstage. But as far as IEM's go, the Zero's have vivid depth and width between the instruments and the vocals. Takeuchi's slow and slightly masculine voice is easily positioned among the array of instruments in the track. The somewhat "misty" atmosphere of the track fits perfectly with the Zero's.

Female Vocals Test: When it comes to female vocals, a clear and concise mid-range is required to achieve peak performance. In this case, the Zero's sounded "engaging". The thickly layered vocals displayed by Case/Lang/Veirs were superbly presented by the Zero's. The inflections of their voices were natural and enveloping. However, alittle more shimmer/ high-extension is needed to launch this song into "detailed" territory. 

Fatigue Test: Being an archaic song recorded in the 1960's, No fun is rash, loud and poorly recorded. The treble spikes are intense, with claps sounding razor sharp and distorted guitars sounding mushy and discombobulated. However, the Zero's are naturally forgiving. The incessantly loud treble spikes and gritty highs are masked over, with a clear mid-range capturing the spirit of the song effectively. From that conclusion, it's safe to say that the Zero's are forgiving of poor recordings. 

Vocal Positioning Test: As featured previously in another review, Dan Bejar's musky spoken word are at the forefront, alongside blaring saxophones and a thick bass-line. The female back-ups are effortlessly easy to pin point . If my head were represented as a 3D ball, the soundstage would be that of a intimate performance. Overall, the vocals are separated with no overlap. 

The Conclusive Sound Description:
After ample usage and testing, it is safe to say that the Zero's are a strong contender in the Mid-fi market. The creamy mid-range, it's smooth forgiving nature and "warmish" tint is suited for all genres. It has a quick sub-bass decay and strong mid-bass punch. The highs are muted and could be lackluster to some. Soundstage is surprisingly large and instruments are easily distinguished (even in poor recordings). 
Do take note that the Zero had a noticeably wider sound-stage and speedier mid-bass slam when amped (the improvement isn't exactly night and day).
Yay or Nay?
It's a YAY (if you're in the market for a easy-going daily listen). It isn't going to dethrone high-end IEM's, but the Zero's are all-rounded and adept at what they do. It is truly a breath of fresh air to see IEM manufacturers doing "simple" the right way. They do the "mid-range" justice and I highly recommend them as a spare beater.

@DaveLT Thanks for your opinion! I'm getting tempted buying one of this wooden gem. They earbud is more of a disappointment but I hope this zero can save that up.


Headphoneus Supremus
Pros: Light and comfortable, and non-fatiguing.
Cons: Detail, clarity, and transparency are generally a bit lacking.
First of all, I would like to thank Shozy for the review sample of Shozy Zero!

I believe what makes Shozy Zero unique is the wooden housing. The driver’s housing is made of high density Brazilian rosewood, the type of wood that is also commonly used for musical instrument. The cable splitter and the 3.5 mm jack barrel are also uniquely made of wood. The simple bullet housing design allows both straight down or over the ear wearing styles. Personally I like the simple and elegant woody design of Shozy Zero. The IEM is very light and very comfortable, even for a very long listening session. I had it for more than a month before writing this review, and so far I don’t see any quality issue on my unit. The only complain on the build quality is the missing of the left dot indicator, and the super small and difficult to see left and right marking. But that can be easily solved, like using other eartips with different color between left and right driver.
There is no information on the website about the driver, but Shozy confirms that Zero is a single dynamic driver IEM. At 94 dB sensitivity Zero needs a little push on the volume as compared to other higher sensitivity IEMs in this category. But just a little, and Zero is still relatively easy to drive and smartphone friendly, though I sometime pushed the volume on my Galaxy S4 to the max for some recordings.


Non-fatiguing, bright recordings friendly.
Light and comfortable.


Detail, clarity, and transparency are generally a bit lacking for distant miking recordings such as classical, and binaural recordings.
Obscured Left and Right markings, no left dot for quick identification.

Suggestions for improvement:

Improvement in detail and clarity.
Clearer Left and Right markings.
Microphone version for smartphones.

Sound Quality

Smooth warm and pleasant sounding are probably best described Shozy Zero sonic character. It has intimate presentation, and in my opinion sounds best with Pop and Vocal. Vocal sounds smooth and intimate with good body, and most important sibilant free. I’ve spent hours listening to Zero using various players and DACs, listening to various recordings. I’ve read some reviews and comments about Zero, and many people seem to like it. I like the fatigue free and vocal centric character of Zero, but frankly, overall Zero sonic character is not really my cup of tea, as it is a little too warm for me, and I generally prefer something with more clarity. But this is more of personal preferences, not really about good and bad. 
With Zero sonic character, some recordings shine nicely, while some don’t. So IMHO, not really an all-rounder, and matching Zero sonic character to the recordings is the key to get the best of it. Many vocal and pop albums sound more pleasing on Zero than for example, one of my favorite IEM, DUNU DN-2000J that cost more than 5 times of Zero. It is sometime tiring listening to Pop albums using DN-2000J due to its analytical signature. On the other hand, listening to classical and some audiophile binaural recordings using DN-2000J is a bliss, while Zero may sounds rather veiled and not transparent enough for those recordings. The recordings we listen play a great role in choosing the right IEM. And from my experience so far, close miking modern recordings such as Pop and vocal are what make Zero shines.
Special venting design on the nozzle for air pressure control:
Tonality of Zero is pretty smooth without any annoying peaks and dips. Zero strongest character is in its midrange. It has mild to moderate emphasize on mid-bass to midrange area, but in a nice and good way, and doesn't sound like a boring mid-centric IEM. Bass and Treble extensions are decent. Bass has decent punch and doesn’t sound anaemic, but doesn't go very deep. Bass is emphasized more on the mid-bass area. Bass speed and texture is average, quite ok for this price range, just don’t expect a very fast and detailed bass. Treble sounds soft and smooth, no sibilant and bright recordings friendly. Upper treble extension rolls off rather early, and perceived clarity and treble sparkle is on the soft side. Dynamic is quite ok, especially for an IEM in this price range. Good enough to make music sounds lively and enjoyable.
Shozy recommended some burn-in, and I followed their recommendation with 200 hours burn-in. I did some measurement before and after burn-in. The measurement result shows that burn-in improves the bass extension of Zero. And from what I can remember, besides the slight improvement in sub bass extension, I don’t remember any other significant changes in sonic character, before and after burn-in. I would say the changes in sonic character after burn-in is rather mild. I’m not a burn-in fanatic, and in many cases that I experienced, burn-in doesn’t always make any significant changes in sonic signature. But in the case of Zero, there are some measureable differences after burn-in. Sonic impression in this review is based on the after burn-in sonic signature.
Before observing the measurement results, please take note of the following disclaimer:
  • Frequency response measurement in this review was done not using standard measurement instrument for in-ear monitors. Therefore measurement result should not be considered as absolute result, and should not be compared to other measurement result using different measurement instrument.
  • Measurement was done using MiniDSP UMIK-1 USB measurement microphone with a DIY acoustic coupler. The program I use for measurement is the famous Room EQ Wizard, REW v5.17 Beta 8. I measured left channel and right channel multiple times, take 3 most consistent measurements for each channel, apply Psychoacoustic smoothing, and then average the result.
  • From my own observation, measurement result beyond 10 kHz doesn’t seems to be reliable, therefore can be ignored.
  • What shown on measurement result does not always correspond well to what I audibly perceived.

Comparison is important to see the value and performance of a product in perspective to other products in the market. Below are the comparisons of Shozy Zero with other IEMs that I have, that are more or less are in the similar price category.
MEElectronics M-Duo
No fight, Zero is clearly better than M-Duo. M-Duo tonality is too V shape with kind of hole in the middle. Besides that the dual drivers inside M-Duo don’t sound very coherent. The treble region sounds kind of detach from the midrange.
Fidue A65
It’s a tie. Fidue A65 shares some similarities to Zero. Both have pleasing, smooth warm type of sound signature. Fidue A65 has slightly thicker bass notes, while Zero has slightly better perceived clarity. Level of perceived detail and dynamic are more or less similar. Both are great for Pop and vocal recordings. Though I like them equally, but if I have to choose, I would probably pick Zero for the little extra clarity. In this case, the measurement result doesn’t correspond well with what I hear, as it shown that Fidue A65 to have more treble than Shozy Zero, but to what I hear, the level of treble is more or less similar.
Audio-Technica ATH-IM50
ATH-IM50 in my opinion is technically better than Zero. Higher perceived detail with better clarity and dynamic. Though sonic preferences is something personal, but objective evaluation is as important. IM50 tonality can be perceived as balance with a slight emphasize on upper midrange to make vocal sounds a little forward. Overall clarity is much better on IM50. Bass and midrange sounds tighter with better texture, and to me that’s very important. Moving from IM50 to Zero I feel that Zero is a tad veiled and congested. So in this comparison ATH-IM50 is a winner in my book. But some people might not feel comfortable with the shape of IM50 and over the ear wearing style, and might prefer the simple bullet shape design of Shozy Zero.

DAPs Pairing

Shozy Zero is not picky on sources, even my old Galaxy S4 drives them quite well with good sound quality. I tested it with some DAPs and DACs, and generally I prefer brighter sounding sources for Zero to give a little boost on the clarity. For example, my Onkyo DP-X1 is a little too dark for Zero, and my old DX-90, Fiio X3 2nd generation, and the new Astell&Kern AK70 match better with Zero. As for DACs, my ifi micro iDSD, Chord Mojo and Geek Out 450 are good choices for Zero. And the Superlux amp I used for IEM comparisons also sounds great with Zero. So far I find Zero is easy to pair and matches well with many of the sources I tried, but I would avoid rather dark sounding DAP like my DP-X1.


Market for sub $100 IEM is quite crowded, therefore competition is very tough. Some comments said that Shozy Zero competing well with IEMs many times its price, well I honestly don’t think so. But within this price category, Shozy Zero actually competes quite well, offering a unique sonic character that many may found pleasing and non-fatiguing.

Edit: It's been brought to my attention by the Shozy team that the Sound Blaster E3 does not play nicely with the Zero. I will be re-evaluating it paired from different devices per Shozy's request.
[color=rgba(0, 0, 0, 0.8)]In the audiophile world, it’s not uncommon to see products promise to deliver great things, often at prices that undercut their competitors. The community loves to take these claims and run with them, often generating hype trains that blow these promises even further out of proportion, leading inevitably to disappointment when the product is delivered. Unfortunately, the Shozy Zero is one such product. While it’s not bad by any means, the Zero (to my humble ears) does not live up to the hype it’s gotten from many a forum on the internet. At $60, the Shozy Zero is already a good value. But in an already-crowded price segment of high price:performance IEMs, does it stand out?[/color]

[color=rgba(0, 0, 0, 0.8)]Preference and Bias: Before reading a review, it is worth mentioning that there is no way for a reviewer to objectively pass judgment on the enjoy-ability of a product: such a thing is inherently subjective. Therefore, I find it necessary for you to read and understand what I take a natural liking to and how that might affect my rating of a product.[/color]
[color=rgba(0, 0, 0, 0.8)]My ideal sound signature would be an extended sub-bass with a leveled, but textured, bass. The mids should be slightly less pronounced than the treble, but still ahead of the bass. I prefer a more bright upper range.[/color]
[color=rgba(0, 0, 0, 0.8)]Source: [/color]The Zero was powered off of a Nexus 6P -> Creative Sound Blaster E3. All music was served as FLAC, ALAC, or as 320Kbps Mp3.

-Sound Signature-

[color=rgba(0, 0, 0, 0.8)]Initial Impressions: These impressions were taken before I’d seen any FR response graphs or measurements. Impressions are taken off of random songs in my music library.[/color]
[color=rgba(0, 0, 0, 0.8)]The Zero has pretty good left/right separation. It’s definitely warm leaning, and took some time to adjust to. The mids seem slightly veiled, but seem less so as my brain burns in. Bass is fast and precise, but isn’t deep and rumbly or boomy. Treble pushes through the mix well.[/color]
[color=rgba(0, 0, 0, 0.8)]Treble: Songs used: White FlagMidnight CityOutlands[/color]
[color=rgba(0, 0, 0, 0.8)]Treble is toned nicely in White Flag, but isn’t the focus of the song. Some vocal effects can sound slightly metallic, but not significantly enough for me to notice the majority of the time. Accuracy and detail is pretty good, but not perfect.[/color]
[color=rgba(0, 0, 0, 0.8)]Midnight City’s electric treble was placed well in front of the song, and had a clear and cutting presentation, without sounding harsh or piercing.[/color]
[color=rgba(0, 0, 0, 0.8)]The violins of Outlands were presented well, but had a certain softness to them.Pairing the Zero with my 6P and M8 brought out the transparency that I look for in classical songs, and helped solidify the edges of the violins that I was looking for. The symphonic presentation that I was looking for is now more present.[/color]
[color=rgba(0, 0, 0, 0.8)]Mids: Songs used: Flagpole SittaJacked UpI Am The Highway[/color]
[color=rgba(0, 0, 0, 0.8)]While I found the vocals of Flagpole Sitta to be rather immune to the muggy coloring of the mids, the guitars and background vocals tended to get caught up in the warm tuning of the Zero. While it doesn’t compromise the sound, it does at a flavoring to it that not all listeners will appreciate.[/color]
[color=rgba(0, 0, 0, 0.8)]Jacked Up’s pianos were resolved fairly well, but didn’t have super clean edges to them. The guitars, piano, and vocals never mixed together or smudged, which is a plus. There is a lot of detail present, and the general timbre of the mids is pleasant and effortless. The Zero does a particularly good job at resolving guitars of both the acoustic and electric type.[/color]
[color=rgba(0, 0, 0, 0.8)]I Am The Highway’s vocals were placed forward and center, making them easily take control of the song, and stay in control. The guitars had a very good attack and decay to them, lending the Zeros a very precise feeling. Upper mids are rather well presented, and sounded full-bodied.[/color]

[color=rgba(0, 0, 0, 0.8)]The Zero sounds like it tuned for optimal performance in songs such as Lights. The mid and sub-bass are present, but importantly, shaped. The bass sounds organic, but is not emphasized too much. This lends the song depth and makes for a pleasant listen.[/color]
[color=rgba(0, 0, 0, 0.8)]Gold Dust is one of the two songs I use to determine how well the Zero performs on the majority of bass-heavy genres such as Dubstep. Once pairing with my HTC One M8, it was easy to see that the team at Shozy did not abandon us electronic music listeners. Sub-bass response is good, shaped, and clean. Believe it or not, it's a night and day difference compared to the bass response on the Sound Blaster E3.[/color]
[color=rgba(0, 0, 0, 0.8)]99 Problems [/color]sounded good, and had a decent amount of depth to it. The more organic and deep bass presentation of the Zero paired with my M8 significantly helps the drums have an impact and body to them, something I really was not expecting considering my initial experiences with the Zero.
[color=rgba(0, 0, 0, 0.8)]The bass-laden intro to Leave Me was rather sonorous and had a good amount of depth to it. The presentation and poise of the song is good, and doesn’t have the “disconnected” feeling to it that I got from my previous test tracks. Even when powered off my M8, I still find myself wishing for a little more sub-bass presence in Leave Me. The bass drops still sound a little too shallow for me to get really into it.[/color]
[color=rgba(0, 0, 0, 0.8)]Clarity: Songs used: ThroneMap of The ProblimatiqueI’m Not Alright[/color]
[color=rgba(0, 0, 0, 0.8)]Clarity is one of the Zero’s strong points, and this is especially evident in Throne and I’m Not Alright. Many of the ambient and background sound effects were present and resolved completely, and there was no notable distortion during the chorus. Instrumental separation is on point.[/color]
[color=rgba(0, 0, 0, 0.8)]Sound Stage[/color]
[color=rgba(0, 0, 0, 0.8)]The Zero’s sound stage is intimate, but not cloistering. It makes for a rather immersive, but not symphonic, experience. Left/right separation is very good during hard-panning. It could use a more air in the sound-stage. I would say the Zero performs right at its price point in terms of staging.[/color]

[color=rgba(0, 0, 0, 0.8)]The Zero is strikingly similar to the Rain2 appearance-wise, but falls short of it in terms of overall musical presentation. While the Rain2 is much warmer, it is just as precise and excels in mid and sub-bass reproduction. It’s got some softened mid reproduction, but lacks the fuzziness of the Zero. All said and done, I think the Rain2 is well worth the $30 over the Zero. The same holds true, even when comparing the two off my M8.[/color]
[color=rgba(0, 0, 0, 0.8)]Zero v.s Rock Jaw Alfa Genus V.2 ($60)[/color]
[color=rgba(0, 0, 0, 0.8)]The Zero and Alfa Genus V.2 have strikingly similar sound signatures. The Zero has a warmer, but less boomy bass and is quicker, while the Alfa Genus V.2 provides more bass quantity. I’ll still have to give the Alfa Genus V.2 the win considering it’s durable cable, inline controls, and tuning-filter system.[/color]
[color=rgba(0, 0, 0, 0.8)]Zero v.s Hidizs EX-01 ($40)[/color]
[color=rgba(0, 0, 0, 0.8)]The Zero’s bass is less emphasized than the EX-01, but is significantly more accurate and quick. The Zero is warmer, but at the same time is also brighter than the EX-01. Bassheads should go for the EX-01, while listeners looking for a more versatile IEM should head for the Zero. In terms of build quality, I’d take the Zero any day. The EX-01’s chromed plastic looks and feels cheap in comparison. I'd say the Zero takes this one.[/color]

[color=rgba(0, 0, 0, 0.8)]Exterior construction of the Zero is very well done. The driver housings are made from rosewood, and the cable is malleable, yet not too thin. It doesn’t tangle too easily, and is smooth enough to not catch on random surfaces. While it doesn’t appear to be too safe from impacts, the Zero doesn’t feel fragile at all. The cable terminates in a straight 3.5mm jack. I wish it would have terminated at 45 or 90 degrees.[/color]

[color=rgba(0, 0, 0, 0.8)]The case is, however, rather nice. It’s a little large for my tastes, but is certainly designed well. You’ll have no problem fitting the Zero into it, and should expect a good amount of shock and impact protection. One side of the case has a net, which is handy if you tend to keep other accessories with your earphones during your travels.[/color]

[color=rgba(0, 0, 0, 0.8)]

[color=rgba(0, 0, 0, 0.8)]The Shozy Zero is a mildly-warm IEM with solid bass impact. It's a great all-arounder that performs very well for the money. With an organic rosewood build, protective carrying case, and attractive cable, the Zero is certainly worth considering for $60. While it certainly doesn't beat more expensive IEMs, it's solidified it's place in my top five earphones under $100.[/color]

Build & Design:
Build quality is about average; not bad, but nothing outstanding. The housings are probably the better made part of the whole Zero IEM, half wood and half metal. The main driver chamber is made of wood and fully sealed, while the front and nozzle part is metal; both parts well attached together. The nozzle is quite peculiar; the lip is cut, apparently for better venting purposes, which seems to work pretty well. The cut is a bit sharp, and mounting the eartips is a bit tricky at first. It'd be better if the lip ends where smoother. The strain relief at the housings is a bit short and stiff, but well glued; the R and L markings are a bit difficult to see. The cable is a bit springy and kind of rubbery. The plug and Y-split are also made of wood, a bit small and lack a proper relief, and a chin slider is also missing. The design itself is quite attractive, like its sound, it looks rather smooth and elegant yet discreet.
Fit, Comfort, Isolation:
In short, really good! This is a strong characteristic on the Shozy Zero. The straight and compact housings are very light and easy to fit and can be worn both down and over-ear ways. They stay fixed and are among the most comfortable earphones I've tried. Just for reference, the fit is similar to the Zero Audio Tenore and Hifiman RE400/600, and just as comfortable. Same goes for the isolation, which is quite good being a sealed back IEM. Some driver flex is present, mainly on the right side (at least on my pair). Microphonics are about average.
The Shozy Zero has a warm, sweet and very smooth sound. Like its design, the sound is very comfortable, relaxed and easygoing, with slight punch, good clarity and a rich tonality; which could be expected for a wooden in-ear.
Bass is not large quantity wise but has good body and decent natural decay. When needed the mid-bass is very slightly enhanced giving some fullness to the overall sound. Quality is rather good without a noticeable bloat, very well controlled but not the tightest or quickest at its price range, and rather limited in depth but reasonably well balanced.
The midrange is laid back, well rounded but not too upfront. It's very smooth and rich, and nicely balanced from low to upper mids and almost clean of any hint of bass bleed. Vocals are sweet but don't carry the best texture; mainly upper vocals can sound a bit off due the lack of treble emphasis. On the whole, the mids show a quite good level detail and clarity. They sound very coherent and have the rather natural texture and richness that 'wood' earphones usually present, but definitely not meant for those who seek in crispness and transparency.
The transition from mids to high is very smooth (even more than from lows to mids). The treble is very delicate and laid back in comparison to the midrange. Probably one of smoothest and most forgiving earphones I've got to listen. Clarity is not as impressive as with the midrange, and might sound a bit dull or off next to a Fidue A65 or Soundmagic E50 which aren't especially trebly sounding IEMs. As a result they Zero won't be as airy and may sound congested at times. The good thing is there are zero hints of sibilance and harshness even with brighter tracks and very forgiving on poor recordings.
Extension is limited on both ends, giving a closer and more intimate presentation. Soundstage is a bit narrow but less compressed than mid-centered in-ear sets such as the A63. Still, the overall presentation is competent for having a more intimate sound.
There's also a very interesting thing on the Zero. It responds quite well to equalization which can help to achieve a better balance.
Zero Vs SoundMagic E50:
The SoundMagic E50 is one of my favorite IEMs among the sub $100 bracket, and one of the easiest to recommend both for its sound and as a whole package. The E50 and Zero share a very good sense of musicality and overall balance, with a rich and full midrange. The E50 is a more all-rounder earphone, having a more solid and extended bass response, as well as stronger yet controlled highs. On the other hand, the Zero is softer in bass and much smoother in treble, with more laid back mids. The E50 wins in build quality, while the Zero might have slightly the upper hand in terms of comfort for some people. Personally, I'd pick the E50 as my daily IEM, but both are very strong contenders.

Pros: Wide soundstage, pleasurable romantic sound, beautiful rosewood, competitive on sound with many IEMs under $200
Cons: Bass definition a little soft with stock tips, midbass/upper bass can be overemphasized, could use more treble extension, few accessories


Thank you Shozy for the review sample in exchange for my honest opinion.



Shozy is a manufacturer out of Hong Kong known for their interesting portable DAC/Amps and price to performance ratio. The company responsible for the brand has also manufactured under the name Cozoy. I think Shozy sounds nicer. The Zero continues in the same price to performance vein where the esoteric Alien and Alien Gold DACs have tread before, but the Zero is a lot more approachable.
Shozy sells the Zero on their website for $60 and notes that there are only a limited list of authorized distributors, check that your local (or not so local) shop is associated with the right distributor.
Like most sensible people I started falling in love with music as a child. My first portable audio device was a Sony Walkman (the cassette kind) that I got when I was 10 years old (24 years ago).  I listened with the cheap Sony on ears that came with the Walkman until I bought a Koss CD boombox and started listening to UAF College Radio and 103.9 (alternative rock at the time) in Fairbanks, Alaska. I once listened to Louie Louie for 3 days straight, and I’m not insane. My musical tastes started out with listening to what my friends liked (Dr. Dre and Green Day) and what my parents liked (The Beatles, Rolling Stones, Bob Dylan) and I only really discovered my own musical tastes and sonic preferences in my late teens to early 20s. What I discovered is that I have very eclectic and some would say weird tastes. I could be listening to gay punk rock, Japanese dream garble pop, 8-bit chiptune, Scandinavian black metal, Latin guitar, the Mariinsky Orchestra, or Miles Davis, but I mostly listen to Classic Rock and Indie/Alternative. I’m a big fan of intelligent hip-hop like Metermaids, Kendrick Lamar and Aesop Rock, also.
I tend to like headphones and gear that are all-around performers, this generally means a balanced or neutral sound. If I have to choose between warm and bright, I’ll choose bright almost every time. A few screechy high notes are preferable to me than a foggy unfocused bass guitar. I somehow never manage to have much money, so I don’t want to buy infinity headphones to switch between my myriad genres that I play. I can hear all the way down to 10hz and all the way up to 23Khz—these are what I’ve heard doing test tones on headphones. It has been a long time since I had a test with an audiologist. I’m sensitive to peaky treble but do enjoy smooth extended treble. I like deep rich tight bass and impactful drums, and dislike upper midbass emphasis.  I like my vocals crisp, so stay away from Josh Tillman’s voice you nasty upper midbass hump.  I hear soundstage better than just about anything I identify in music, but my words haven’t caught up to my ears. I listen at volume levels that others consider loud (72 to 75 dB), but I just set it to where the dynamics peak. I’m not here to shatter my eardrums. I like them just how they are.
I generally don’t believe in using EQ, not even for inexpensive headphones, especially in reviews. I won’t claim that I haven’t done it, but I generally try to avoid it.
I’m a firm believer that cables can make a difference, but I don’t think they always do. When I tried out Toxic Cables line, none of them had labels and the cheapest looking one was the one I liked the best. I was excited that I wouldn’t have to spend much to improve my sound. It turned out that the cheapest looking one was the Silver/Gold top of the line cable. I’ve heard the difference that USB cables can make, from upgrading from the crappy cable that came with my Geek Out 1000 to a Supra USB, and then again when upgrading to the LH Labs Lightspeed 2G with the iUSB3.0. When I picked up a cheap shielded power lead from Mains Cables R Us (who also sell iFi gear) to replace my standard kettle lead on my amplifier, I heard more crunchy and clearer treble. I switched the leads with my wife blinded and she heard the same difference. I didn’t tell her what I heard and let her describe it herself. But cables don’t always make a difference. When I switched from my standard HD650 cable to a custom balanced cable (Custom Cans UK, very affordable), the sound stayed exactly the same when hooked up via a top tier (custom made by @dill3000 silver/gold) 4-pin XLR to 6.3mm converter. Balanced mode made a difference in clarity and blackness of background. Your mileage may vary and you may not hear a difference, but I have.


Vital Statistics (specs from manufacturers and distributors)

In this section of my reviews I try to let the manufacturer’s story about their product be told. Manufacturers and retailers always have something to say about their products, some of the time it’s accurate. The review sections will tell whether that is the case here.
Shozy doesn’t provide very informative information on their website, and has it formatted in a way that makes copy/paste onerous, the whole page is a jpeg. Shozy should definitely improve on making their website not just pretty, but functional. You can put lipstick on a pig, but you probably won't want to take that pig to the village dance--I don't presume to know what your community does. I’ve chopped the relevant bits up for you here.
Try googling pig with lipstick, you'll get racism, misogyny, judgemental religious blogs, and other fantastic things besides this great image. She's so stylish, she even knows how to wear pearls. Better trot out your best Sunday suit.

Conspicuously missing from the specs were driver size and impedance. Whilst the driver size isn't listed, it's a pretty safe bet to say between 8 and 10mm. The website says of low impedance. I have no idea what this means, but I'm guessing it means somewhere around 16Ω.
As can be seen, Shozy kind of sucks at drawing graphs. The scale here is obviously not linear, which makes it difficult to discern where that heavy roll-off really starts happening. That dip that drops down to 0 doesn't look so good to me. Luckily, it sounds better than that graph makes me feel. Maybe I just suck at reading graphs. After all, I've used the XKCD cartoon below for teaching economic modelling.


Form & Function

The units I received were one of many beta units sent out into the wild by Shozy, and I was very happy to be approached. My unit came in a simple padded mailer with no case or retail packaging, so I can’t comment on the packaging first hand. These are the accessories listed by Shozy as coming with the IEM:
  1. Carrying pouch
  2. Single flange eartips (S/M/L)
  3. User manual
The stock tips have a very wide bore, which I found to increase stage width but decrease bass definition. I preferred the slightly smaller stage and improved overall definition and clarity of the spinfits. One interesting thing on the nozzle is there is a little notch on the bottom. Shozy indicates that this is for tuning, but I found that it also makes it easier to get tips on. The Shozy Zero has quite a large bore and loading the tips over the notch makes fitting tips much easier.
Overall the accessories are pretty bare, but are acceptable for the price range. There are headphones at lower prices with much nicer accessories, like the Brainwavz Jive. This is an area where Shozy could improve here, but from what is listed on, the cost of the wood might necessitate the price, and further accessories may cut into margins too much. According to Penonaudio:
SHOZY Zero in-ear earphones use simple in-ear design, wearing comfortable. Earphone front shell is  precisely processed by lathe and CNC,it has a remarkable acoustic structure designed to allow normal speaker releasing excellent sound; the rear shell, splitting and the plug shell, and are using good quality red sandalwood, precision lathe processed, carefully selected (1500 sets of wooden shell can pick out only about 300 sets). Imported speaker driver, high-sensitivity low impedance, mobile phone can drive it easily, if play with the high-end players and decoding amp, sound quality increase significantly and clearly.
The description on Penonaudio using ‘red sandalwood’ is not an error, as rosewood and red sandalwood are varieties of the same family. Rosewood is known for its excellent density, which makes it desirable in audio and woodcarving applications. Suffice to say that rosewood, a less expensive variety of red sandalwood, is still an expensive component.
Something to note ahead of getting into all this. I was advised by Shozy’s representative to burn the headphones in using classical music for at least 100 hours, preferably 200 hours. I think that this is a completely unreasonable amount of burn-in for a $60 headphone. If it requires this much burn in, most of this should be done at the factory. I’m also of the opinion that music doesn’t give drivers the same exercise as noise. I would usually burn-in headphones using what I’ve coined ‘Neapolitan noise.’ Neapolitan noise is white noise, pink noise, and brown noise; it’s like vanilla, strawberry and chocolate ice cream combo bricks you find in your grocery freezer section. Noise gives a more full frequency workout that reduces time to burn in drivers completely, and I’ve found that most headphones after 20 hours of noise exhibit no further changes. I have run into headphones that change around 50 hours, but there aren’t many. For the Zeros, I followed the manufacturer instructions, mostly. I tested them at zero, 20, 50, and 100 hours and noted that there were changes along the way. After 100 hours I gave them some Neapolitan noise to firm them up. The zero is more strident at first blush and mellows out over time. Give it due time.
  1. 3 minutes white noise
  2. 3 minutes pink noise
  3. 3 minutes brown noise
  4. 2 minutes digital silence
The noise is off the Ayre Acoustics – Irrational but Efficacious System Burn-In Disc, and the 2 minutes of digital silence is off of Binkster Audio Test CD. The digital silence is necessary, as the workout that is being given to your drivers is strenuous. They need periods of rest. Burn-in should be at normal listening to slightly louder listening volume. Don’t blast it unless you want to ruin your drivers. After burn-in some drivers will need a little time relaxing with music to settle. Give a few hours before making judgments on sound. I’ve had drivers sound fragile after burn-in, but they recover from the stress.

Audio quality

The Shozy Zero has a warm mid/upper bass emphasis with smooth and pleasant sounding treble that does very nice with violins. I found that with the stock tips the bass could be a little fuzzy. A bit more control would be an improvement. The sound stage has good width but depth is superficial. You can hear the relative weight in the stage of instruments at different depths, but you can’t feel the air moving through and around instruments. It is like a painting done with broad brush strokes versus a painting using finer strokes. Both are pleasing, but the details are far superior when the more delicate brush is used. Instrument placement could be more palpable, with better separation in the depth dimension. Soundstage height is excellent on the Shozy Zero. I think the stock tips trade off some detail in order to blast out an impressively wide soundstage.
Switching to Spinfits, which give the bass more control and crispy up the treble a bit, I tried the Shozy Zero with a few DAC/DAPs. The Cyberdrive Feather DAC (a crazy bargain at current prices, $30 on IndieGoGo for DSD256 native DAC) is a nice pairing. The Feather DAC is a bit bass shy, so it controls some of the excesses on the Zero. I prefer a bit less emphasis on bass quantity, and more emphasis on bass quality most of the time, and the Feather tones down quantity nicely with the Zero. Soundstage height is still exceptional at this price. The LH Labs Geek Out 1000 is also a good pairing. The GO 1000 is fairly neutral with a bit of treble emphasis giving it a sharp sound that can be a touch metallic. This works well with the Shozy Zero. The iBasso DX50 has a bit of emphasis in the midbass to lower mids, which is where the emphasis is on the Zero also, so it didn’t make as good a pairing. The Opus Audio Opus #1 is a great pairing for anything I threw at it as it is sublimely neutral and was no different with the Shozy Zero.
When compared to the MEE Audio Pinnacle P1 (link to review), listening to Father John Misty – The Night Josh Tillman Came to Our Apartment, the Shozy Zero has more soundstage width and height, but lacks the definition and depth. The Shozy Zero has a romantic quality to it that many will find inviting. It has more forward mids and bass, and smooth treble that doesn’t extend as well as the Pinnacle, which makes it a less detailed sounding IEM, in comparison. Detail is still good with the Zero. I use Josh Tillman’s voice to check whether the midbass is bleeding into the lower mids and colouring the sound. Whilst there is emphasis in the midbass and upper bass, the Zero didn’t colour Josh Tillman’s voice, which made me very happy.
Listening to San Francisco Symphony Orchestra – Concerto for Organ with Percussion Orchestra - I. Allegro (off American Mavericks), with the LH Labs Geek Out V2 as the DAC (low gain, 100mW) the Zero keeps pace well and has good impact, but the 64 Audio X2 is a bit more composed with a greater sense of depth and a bit more impact on drums and percussion. Downloads now has a slew of fantastic recordings, and I particularly enjoy San Francisco Symphony Orchestra recordings. Concerto for Organ with Percussion… is a fantastically lively 5 and ½ minute track. I love me some percussion, and own four or five hi-res percussion albums from 24/96 PCM to DSD256. About the 64 Audio X2, which is relatively unknown, it was a Kickstarter exclusive fixed cable version of the 64 Audio U2, which retails at $399, so it is very impressive that the Shozy Zero is performing on similar level. I much prefer the 64 Audio X2, but it isn’t an open-shut case, and others may have different views. Both are excellent sounding. On Rage Against the Machine – Killing in the Name, the 64 Audio X2 is a bit cleaner and sharper with a slightly more balanced sound, which is more to my sound preference. On Be’Lakor – Abeyance/Remnants of the dynamic range laden metal purity Vinyl remaster of Of Breath and Bone, thanks @Trogdor (follow him on twitter @MetalFi), the 64 Audio X2 has much better bass texture, clarity, instrument separation and depth. The 64 Audio X2 is just better than the Zero, in my opinion.
Versus the Fidue A65 (link to review), the Shozy is a touch warmer and a little bit less crunchy.The signature of the Shozy is more restrained, with a bit more depth and width to the stage. The Fidue A65 has a more forward energetic signature with more brightness. Both are stellar performers in the price range. The Fidue A65 can be had from Hi Fi Headphones, locally in the UK for under £50. In a strange note, I’m pretty sure the rose gold Fidue A65 have the exact same cable as the Shozy Zero. The less sexy silver ones I have on hand have a black cable, so I can’t confirm if it is the same.
The Zero is really easy to drive. The Feather DAC doesn’t have much power, but it drives the Shozy Zero plenty. I like the Zero best with the Opus #1 and the Geek Out V2, two very neutral dacs with good strength in detail resolution.



The Shozy Zero is an excellent under $75 IEM. In fact, it is an excellent under $200 IEM. I don’t know if the joke on HeadFi is apocryphal or true regarding the Zero being designed to compare to headphones with an extra ‘0’ on the price, but I found it competed very well with all my sub $200 offerings.
This is a beautiful headphone made with premium wood with a warm and pleasurable sound. The soundstage is impressive for the price. It has smooth treble with a warm inviting sound that many will enjoy. I like a little less emphasis on the upper bass/lower mids, but this is a small quibble. Even with this emphasis, details are still good but do not beat the MEE Audio Pinnacle or the 64 Audio X2.
The Shozy Zero is well worth picking up for the low price of admission and competes very well with more expensive offerings.


Pros: Lightweight,Easy to drive,Bass extension,Detailed,airy and Smooth sound,Non-fatiguing,Looks,Value.
Cons: Slightly rolled off treble,Driver flex,L-R marking hard to see.
The Zeros that I'm reviewing today has been provided to me by Shozy for an honest and unbiased review,for which I'm honoured.The unit that I had received is a BETA UNIT so the retail unit may slightly differ.As mine were pre-production unit they came in a small plastic bag along with 3 stock tips.I'll try to give honest impression about them.The zeros can be purchased for 60$ from here -

About Me:
I'm a student who has just got on the head-fi tour.I've joined this community before a month hence you can understand about my experience regarding to such stuff.My preference in music is Rock,Country music and Indie Pop.I'm not a basshead,I like neutral to warmish sound.As I'm a newbie and this is my 1st review so please bear with me for any mistakes.
Sensitivity(at 1Khz) :94db
Frequency response :20hz-18Khz
Input connector :3.5mm/1/8 inch gold-plated stereo TRS plug
(From official website)
Build Quality:
The housing of Zeros is made of Rosewood and metal.The audio jack is gold plated and made of resewood housing.The cable of the zeros looks good,though I feel the cable is not much sturdier but I've been told that the retail version will have better build quaility so take it as a grain of salt.The L-R markings are very hard to see.As photography is not my thing I've attached some pics of retail unit from Penon Audio.
Fit and Comfort:
They are very lightweight.I can plug them in for an entire day.You just forget that they're in your ears.They're so tiny and comfortable.The stock tips are pretty good and gives a proper fit.They can be worn both straight down and over ear.
Sound Quality:
Coming to the main part the sound signature of the zeros is neutral to warm.The zeros definitely require burn-in for about 150hrs.Before burn in they sounded quite moody,rolled off and congested.After nearly 150 hrs of burn-in they really opened up and the sound gets more defined and spacious.So I would suggest to burn-in them and then evaluate them.The sound tonality is very smooth,airy and detailed.
The lows are very defined having a great extension.Lows are deeper and have wide spectrum.The mid bass is slightly overpowering.The sub bass is very natural and punchy.The upper bass sometimes interferes with the mids.Other than that lows are great on Zeros.

Mids are full of lush.Both the male and female vocals sounds natural.The mids are very enjoyable along with great details.No sibilance,No harshness.IMO best within this price range.

Heighs are smooth having enough body.Highs are slightly less detailed.The treble sometimes can be rolled off,it really Lacks some details and seperation.Though considering the price it's acceptable.
Soundstage and Seperation:
Zeros have very good sounstage.The depth is great but the width is slightly on the narrower side,though it has enough width to enjoy the music.Instruments sounds well positioned.The sound signature is airy and spacious.Separion is not top notch but good.
It highly depends on the tips you're using.Personally I feel the stock tips does give below average isolation.However comply tips provides better isolation.
Since I'm new I don't have a big iem collection but I've RHA MA750,SONY MDR-XB90EX and VE MONK+.Currently due to my study I'd not be able to give justice to such comparision.Though one can pm me if he's interested in such comparison.
The Shozy has really nailed it considering the Zeros are their first iems.As we all know no iem can be perfect,the Zeros have their ups and down but believe me the sound is very fun and engaging along with awesome details and spaciousness.The 60$ price is a steal.If you're after iems under 150$ you should definitely not miss out the Zeros if you want smooth sound signature along with great details and excellent bass.Excellent bang for the buck.
I'd like to thank the Shozy Representative who provided the review unit.
Thanks to the readers for giving time to this review.
Pardon me for any mistakes and silliness.

Headphoneus Supremus
Pros: Great sound, comfortable (light weight), price, appearance
Cons: L/R markings are hard to see, cable has memory and doesn't inspire confidence
First, I would like to thank Shozy for sending me a pre-production model of the Zero in exchange for my honest opinion.
My pre-production model arrived in a small package. Inside was the Zero along with 3 sets (S/M/L) of black silicone ear tips. It is my understanding that the full production model comes with more accessories (namely a case and a box).
Build Quality - I've knocked off a star due to the cable. It has some memory, is thin and doesn't inspire confidence. I don't know, quite frankly, how it will hold up over time. Another factor for the reduced star is that the left/right markings are very difficult to see. You have to look very close in good lighting to tell. Some red/blue color banding would have been nice. The rosewood on the jack, y-splitter and IEM housings seems to be excellent quality with an elegant touch. No complaints there. The ear pieces are small and also very light weight which means you hardly notice they are there. 5 stars for comfort and fit.
Isolation - Isolation is about average for an IEM.
Sound - Now for the most important part, the sound. To my ear, the Zero is very balanced with slightly elevated bass. The bass is very well done though and doesn't interfere with other frequencies. IMHO these are not basshead IEMs. They aren't bass light either. It's just the right amount for an enjoyable listen.
The mids and vocals are very smooth and engaging. Vocals are slightly back in the mix. Not enough though that I would deem these a drastic "V" shape FR response (more "U" shaped). They are actually more forward compared to several others I have in my collection (e.g. Xiaomi Piston, Rock Zircon, TK12).
Treble is very polite and non-fatiguing. Details are excellent for an IEM in this price range. It's not a detail monster though, so for critical listening look elsewhere (e.g. BA's or BA/DD hybrids).
Concluding thoughts - What Shozy has done with a single DD is really amazing. Cable notwithstanding, I think these are a great value for the $50-$60 that they go for. I've sold IEMs in the past because of fit/comfort alone (e.g. Ultimate Ears TF10). The great fit and comfort these have adds value in addition to the great sound.
Highly recommended for all genres!!!
Notes: 1) All sound impressions were using an Xduoo X3 DAP with FLAC or 320kbps MP3 files at moderate listening levels. 2) Per manufacturer's recommendations, IEMs were "burned in" (i.e. played at moderately high volumes) for a minimum of 200 hours. 3) Stock tips did not provide a good seal for my ears. Therefore, JVC Spiral Dots were used instead.


100+ Head-Fier
Pros: Very good clarity, reasonably detailed, inexpensive
Cons: A bit too bassy for some
Disclaimer: I received this earphone for free from the manufacturers. I did my best not to let that color my opinion on the product, but my impressions may not be entirely without bias.
Shozy Zero is a high quality value-oriented earphone, providing listeners with impressive sound in an attractive package, for a relatively low price. It is primarily focused around its powerful bass response and mostly clear midrange, placing treble a step or two back in the mix. The sound of the earphone is clean and detailed, from top to bottom, and is competitive with many options within its price range as well as some above, though the bass may distract the listener slightly from the lower midrange. I also perceive some upper midrange recession, reducing the energy, but not the clarity, of female vocals and higher pitched brass. The real selling point of this earphone is how clean it sounds; it reveals an impressive amount of detail in any track and I never perceive it as sounding muddy or unclear.
Ultimately, the sound this earphone reproduces is very good, and is competitive with many other earphones. Having heard several other earphones in a variety of different price ranges, I would easily recommend this as a high-value option for listeners who are not aiming to spend a great deal to achieve good sound.
There isn’t much more to be said about Shozy Zero. Put simply, it sounds good, it looks good and it won’t break the bank.
EDIT: Given further time to listen and to burn in the earphones, I cannot discern any appreciable difference in the sound quality of Shozy Zero. They earn a fantastic recommendation for anybody looking for a warm, bass tilted sound signature without sacrificing clarity and detail in the process. They are very respectable earphones and are genuinely a great option at their price range.

My rating for Isolation is not reflecting what I tried to report in my review. Isolation should be rated considerably lower.
The ratings are averages from all reviews.
Oh. Whoops. It had been some time since I'd reviewed anything on Head-Fi when I had submitted this, so I did not remember that was the case. Thank you for letting me know.
Pros: Very enjoyable sound signature, Natural wood housing and jack are cool, Sound outperforms price tag
Cons: Flimsy and rubbery cable, Notch on nozzle ring makes tip rolling a pain, Reported variances in tunings
At the time this review was written, the Shozy Zero in-ear monitor was for sale at Here is a link for purchase:
Being on Head-Fi for the last three years, I’ve learned whose opinions and impressions of products I should trust. One of those opinions is my good friend Tamal’s. When he said that Shozy was releasing a new in-ear monitor and it sounded great, I knew it would be something I should check out. Needless to say, the Zero sounds excellent. Today we will go over it with a comprehensive review
I was given an opportunity to review the Zero in exchange for my honest opinion and review. I am in no way affiliated with Shozy. I would like to take this time to personally thank the good folks at Shozy for the opportunity, and my friend @RedJohn456 for the recommendation. If you are unfamiliar with Shozy, they make some really good portable DACs, amplifiers and a unique screenless DAP called the Alien. Here is alink to their site if you’re interested:
My Background
I AM NOT a numbers and graphs audiophile or sound engineer. Personal audio enthusiast? Absolutely! Headphone junkie? Possibly…
There’s something about quality DAPs, DACs, Amplifiers and Earphones that intrigues me. I want to hear any earphone that looks promising, in hopes that I can share my impressions with  enthusiasts and help them find the audio product they’re looking for. My Head-Fi profile has a list of audio products ranked from favorite to least favorite. For me, this hobby is more about getting great price to performance ratio from a product, while having a variety of different gear to mix and match. With personal audio gear, we tend to pay a lot of money for minor upgrades. One thing I’ve learned over the last few years is that just because a headphone has a higher price tag, it doesn’t mean that it has superior build and sound quality.
I’m always looking for great audio at a great price. I’m after headphones and IEMs that give me the “WOW” factor. I can appreciate different builds and sound signatures as long as they are solidly built, with ergonomics and sound that is pleasing to my ears. It’s my pleasure to share my experiences with audio products and make recommendations based on gear I have owned and used.
Because I received a beta unit, I don’t have the retail packaging and all of the accessories. Because of this we will skip the unboxing section of the review.

The Shozy cable is a thin and rubbery cable that seems fairly durable. There is a small amount of spring and memory. The cable will be subject to tangled if not handled in a manner that prevents this from happening. Zero’s Y-split and cable jack are both made with the same real rosewood material as the housings. The cable jack is a straight style gold plated 3.5 mm plug. Strain reliefs are subtle and adequate.
While I know that real rosewood and awesome sound quality are great aesthetics for an in-ear monitor in this price range, the Zero cable is on the cheaper side of things. I would have rather seen Shozy charge an extra twenty dollars for a more premium attached cable with a chin slider.
The Zero has no microphone or remote. They are a plug and play device. Plug in, play music, enjoy the sound, repeat.
Ergonomics, Fit and Microphonics, Isolation
First things first, getting a proper fitting tip that seals well can be a challenge. None of the stock tips worked for me. I ended up using a gray and red tip purchased from Lunashops. The bore is wide enough to fit over the nozzle and they sealed well. Make sure to try and accomplish the same with your Shozy Zero and you will be rewarded with some great sound.
The Zero is a very standard fit that works both over and under the ear. Because there is no chin/neck slider, when wearing them over the ear I prefer to use aftermarket ear guides. This  prevents the cable from unlooping from over the top of my ears.
Wearing them under the ear, I get a considerable amount of cable noise. Wearing them over the ear, microphonics are pretty much a non-issue.
Sound Review
I did my demo with my usual gear. I used an LG-V10 for smartphone use, and either my Shanling H3 or iBasso DX80 DAP for high fidelity portable use. For desktop use, I used my Toshiba Satellite Laptop in combination with a ifi micro iDSD playing at 32/192 kHz. I tested them with several other sources as well. I used Google Music in its highest download quality (320 KBPS), and also streamed FLAC via Tidal streaming service. I also used purchased and downloaded tracks in MP3, FLAC, WAV and DSD. I make sure that any gear I test has sufficient playtime before writing a review.
I used my usual same songs for testing gear:
“Limit to your love” by James Blake (bass speed, punch, response)
“Doin’ it Right” by Daft Punk (sub bass)
“Get lucky” by Daft Punk (bass to midrange transition resolution, male vocals)
“Madness” by Muse (soundstage, separation)
“Some nights” by Fun (soundstage and male vocals)
“The soundmaker” by Rodrigo y Gabriela (texture and imaging)
“Bassically” by Tei Shi (bass to midrange resolution, female vocals)
“Skinny Love” performed by Birdie (female vocals, acoustic playback)
“One” by Ed Sheeran (male vocals, acoustic playback)
“Outlands” from the Tron Legacy Soundtrack (symphonic presentation, imaging)
“Sultans of swing” by Dire Straits (detail, separation, balance)
“And Justic for All” by Metallica (driver distortion, treble response, rock playback)
“Ten thousand fists” by Disturbed (driver distortion, treble response, rock playback)
Note: Other tracks were used, but the listed songs were primarily used to assess and break down the gear’s response.
Source Selection
Shozy doesn’t share any specifics in terms of impedance or driver size. If I had to guess, I would say they fall somewhere between 25-35 ohms. They work good through just about any portable source I used. They sound great with a smartphone, and scale up well with DAPs and portable DACs and amplifiers. The better files and sources you use, the better the Zero will sound.
A neutral and more linear source will make them sound very natural with a warm tilt. Using a warmer and bassier source will make them follow suit. A very minor warm tilt isn’t pushed overboard by colored sources.
Plug Zero into your favorite source and play your favorite music. I can almost guarantee you’ll enjoy their sound with any quality source you use.
Sound Signature
The Zero has been reported as bassy and smooth. While I agree with this to a certain extent, I feel the Zero is a very natural and relatively balanced sound. Rather than say bassy, I would classify them as slightly warm tilted and non-sibilant. They are spectacular for their price, and beat many earphones that cost twice as much in terms of sound quality.
Putting price and performance into perspective, the Zero is fabulous. In this hobby, budget earphones often times perform at a level that ALMOST matches and rivals the summit-fi gear. If there’s anything that would make me say that Zero doesn’t do that many of my favorite (and usually much more expensive) earphones do, it doesn’t have the same airiness, detail and clarity I’ve heard from the best earphones available. Still, the Zero rocks in these regards, it’s just not on the most elite of elite levels. Simply put, the Shozy Zero gets my approval as being flat out awesomesauce. They are hard to fault. People are going to really like these things.
Bass on the Zero is very balanced and packs equal amounts of punch and rumble. There is a slight tilt towards a bass emphasis, but it’s tastefully done.
Sub bass tones extend well and will satisfy a diverse range of music lovers. When listening to bass lines of various genres of music, the Zero handled all tones with a quality level of resolution and response. Nothing seemed lacking. The Zero has deep soundstage that sounds very natural.
Midbass is in good proportion with the sub bass response and well done. There’s enough midbass to give them good dynamics, and not enough to be boomy or sound unnatural.  
A slight downward tilt from midbass tones leads to a dynamic lower midrange. This theme continues in slight downwards slope until reaching a small bump at upper midrange frequencies, giving vocals a nice sense of energy. All vocals and instruments have a warm tilt and nice bite at upper frequencies, making the Zero a very entertaining earphone.
Zero’s treble will be a hit with most people who listen to them. Simply put, the Zero has a pretty sizeable drop off at sibilant sounds. The dip takes place at a frequency range that makes the dip seem natural and far from harsh. Treble picks back up after 10 kHz, giving the Zero a sense of good extension. For me, the treble presentation of the Zero was probably my favorite part of their tuning. Their smooth and extended response in combination with the slight warm tilt and extension at sub bass tones makes them incredibly fun and non-fatiguing listen.
Soundstage and Imaging
The nice sense of depth and extension makes the Zero’s soundstage above average. A decent sense of clarity and balance gives them a decent sense of imaging, but the warm tilt prevents this from being elite.
VSONIC GR07BE ($85 to $150 USD on many sites)
The GR07BE is a hall of famer, sporting a bio-cellulose driver, articulating nozzle, and secure over the ear fit. It is a sentimental favorite, as it was the first earphone purchase I made that eclipsed the hundred dollar mark.
Comparing the two, I give a slight edge to the GR07BRE in terms of bass response. There’s something about the GR07BE combination of soundstage depth response that to this day is world class. Still, the Zero is no slouch, and is edged out by the slightest of margins. Midrange of the GR07BE is much drier and recessed as compared to the Zero. I prefer the warmer and more dynamic lower midrange of the Shozy offering.  Treble on the Zero is much smoother than the somewhat sibilant GR07BE. My ears need a minute to adjust with both earphones when bouncing back and forth. The Zero is definitely the less fatiguing earphone of the two. Overall, this is an incredibly close contest that comes down to what I’m listening to and source I’m using. I’m going to end this by saying it’s a tie in terms of sound quality.
Build quality, accessories and fit/comfort goes to the GR07BE. I wish Shozy would have increased the price and put a more premium cable and chin/neck slider, and also offered more in terms of tips and accessories.
At the end of the day, the Zero is a smoother and less fatiguing earphone that can be worn under or looped over the ear. They come in at a much lower price tag, which leaves it up to the consumer whether the GR07BE tuning and over the ear fit is worthy of the increase in price.

Trinity Hyperion-Discontinued ($65 USD when for sale)
The Hyperion is a titanium microdriver earphone with a V-signature. They have an incredible cable and small metal housing.
Comparing the two, the hyperion has more sub-bass to my ears. Although it has tremendous depth that trumps the Zero, it can also be a bit boomy with some tracks. Although being a V-signature, the hyperion has some rich and full bodied midrange that is very entertaining. Still I give a slight edge to the Zero mids, as they are a bit more airy and balanced with the rest of their frequency ranges. Treble on the Hyperion is a bit crisper and more natural on the Hyperion, but can also be harsher at louder volumes. In terms of entertainment factor, I prefer the Hyperion. In terms of being non fatiguing and for long listening sessions, The Zero gets the upper hand.
Build quality and accessories goes to the Hyperion. Their cable is awesome, and tiny metal housing is very cool. In terms of which one to get, Zero is the only option at this point. Again, if being forced to pick one or the other, I can’t. They are both excellent in their own way.
The Zero is one of the best sounding earphones in the sixty dollar range. The real rosewood they used is awesome. The cable they used isn’t the greatest and leaves room for improvement in their next earphone release. Their sound is fatigue free, relatively balanced and dynamic. Their sound quality will impress many who listen to them.
Shozy has already established a great name for themselves with the Alien DAP and portable DACs and amplifiers. It’s very cool to see they can manufacture an very nice pair of in-ear monitors as well. I highly recommend the Zero IEM. They are a universally great tuning that will work with any source.
Thanks for reading and happy listening!
Great review and very very nice playlist! Thanks!
Wow didn't know zeros were comparable to gr07be...
*interest intensifies*


100+ Head-Fier
Pros: Lush Mids, Lifelike Vocals, Non-fatiguing, Isolation, looks, comfort, beautifully built, great value
Cons: Rolled off trable, Mid bass emphasis, long burn in(>200hrs), Not too fast, Lacks proper R/L markings
Hello again guys, I am Areek Nibras, a junior Head-fier and a recently graduated physician from Bangladesh, currently doing post-graduation training in Internal medicine. Today I will be reviewing the recently released in-ear monitor by 'Shozy'. It's called the 'Shozy Zero', Now, Shozy is a HK based company, who have been producing portable audio equipments since 2012, a few of their well known products include the Alien DAP, Lancea DAC+AMP, Cygnus earbuds, but the Shozy Zero iem's are their 1st step in the in-ear monitor catagory which currently goes for around 50$(shipping excluded), sold by various online sellers and even massdrop. I was mostly unaware of the company, only hearing about the Alien before, so I was quite curious when approached by Shozy, who offered me a pre-production pair in exchange for my honest review but with one catch, burning these in for more than 150 hours with orchestral music. I agreed, and after some days, I got a small envelope with the IEM in it. I must thank the entire Shozy team for letting me review these.
I tested the iems in both my pc and portable setup and my phone. I have given then more than 250hrs of burn in, which is 100hrs more that the required. I've mostly listened to music as well as movies and gaming. I'll try to describe my overall thoughts in this review, as well as do a comparison with the Fiio EX1 iems that I own.  
I have received the Shozy Zero as a free unit after agreeing to reveiew them in exchange for my honest opinion by Shozy. I am in no way affiliated with Shozy. The review I'm posting is just my opinion regarding the product and it was not influenced by any means by Shozy or anyone else. 
SPECIFICATION (taken from Shozy's web page)
Sensitivity(at 1Khz) :94db
Frequency response :20hz-18khz
Input connector :3.5mm/1/8 inch gold-plated stereo TRS plug
As I was told, the 'Zero' I received is a pre-production model. I got them in an envelope, which contained a transparent plastic pack with the IEMs  in it. There was also a smaller pack containing 3 pairs (S/M/L) of black silicone earbuds. The retail packaging is supposed to have a carry on pouch, but it was not provided considering it was a pre-production unit. 
5K1A0066.jpg    5K1A0052.jpg 
The shozy zero is a gorgeous IEM, beautiful rosewood shell containing the earpieces which are well polshed and give a premium feel. The nozzle is black plastic and the ending has a small notch on the bottom part. The cable comes out from the bottom part of the wood shell, there's a stress relief present on which L & R markings are ambushed on black. The markings are really small and as the iem is quite symmetrical, there is no obvious way to identify the lt. and rt. earpieces without taking them closer to the eye.
5K1A0046.jpg    5K1A0064.jpg  
The cable is relly thin but build is pretty strong. It has a matte black and brown spiral design, which looks beautiful. The the lt. and rt. cables meet up at a Y split made of rosewood which has 'Zero' inscribed on it. There is no chin-slider present. A thicker cable continues down from the Y-split and terminates at a 3.5mm gold plated stereo jack, the connection enclosed in another rosewood shell which has 'Shozy' inscribed on it.
 5K1A0056.jpg   5K1A0059.jpg
Now, lets talk about comfort and fit. These iems are designed to be worn straight down although it's also possible to wear it over-ear. These are really light so it does not matter how you wear it. I found it to be comfortable straight down. The silicone tips that came with it are good enough and are supposed to produce the best sound. I found that the medium tips fit me best and provide adequate seal and isolation. The lightness and the fit makes these one of the most comfortable iems i've used till now, I have worn them for 5-6hrs straight without any discomfort. 
So, if I were to change or do some cosmetic upgrades to the zero, those would be the following- 
-More visible L/R markings (can't stress enough)
-Chin slider
-A shirt clip
Appearance- 4.5/5
Build- 4/5

Accessories- ~/5
Fit- 4.5/5
Comfort- 5/5

I've always considered myself to prefer a balanced sound with a bit of warmth and sparkle at both ends. My HE-400 and the Fiio EX1 both seemed to me serving me according to my needs, sometimes a bit too much (treble) perhaps. The Shozy Zero is unlike any of those, these throw good warmish sound with great vocals, lots of micro-detail and comfort on the table in expanse for sparkly highs and soundstage. As i've mentioned before, these had a really long burn-in time and the tonal changes it offered during this period is a journey itself. I'll be discussing my impressions bit by bit here.
Gears used- 
PC > JDS labs Odac+O2 > Shozy Zero ( 2.5x gain, 11/12 o' clock position)
Fiio X1 > Fiio E12 > Shozy Zero (low gain, 11/12 o' clock position)
Oneplus One > Shozy Zero (70-80% vol, AudioFX disabled)
I was requested to burn these iems with more than 150 hours of orchestral music. In threads discussing these, some people even recommended burning these for more than 200hrs. Although I was ridiculed at first hearing the time required, after listening to it, I did believed these go through audible changes by burning in. So I decided to give these more than 250 hours of burn-in with tracks by Mahler, London Philharmonic Orchestra, The Cinematic Orchestra and several other orchestral music I had in my collection. I've also listened to my regular music track in the meantime in specific (and non-specific) intervals to see how these were changing up.
1st impression- Out of the pack I hooked these up to my portable setup and played some of my most favorite tracks (Tracy Champan-fast car, Eagles- Hotel California, Hot Chelle Rae- Bleed and few others). The 1st thing that came into my head was- wow, these have some amazing mids. The vocals, piano and violins sounded great from the start. But other frequencies sounded muddy, bass lacked any control, the trebles were almost non-existant and I felt like somebody put a wall in between these and my ears. The isolation was great from the start as soon as I got the best fit. Then I started the burn in.
30 hours in, mids and vocals held the same tonality but the bass were a bit tighter, still some flabbiness in them. Highs also seem to be clearing up. But still lacks any sparkle and clarity. 
At 50-60 hour mark, the bass seemed to have improved a lot. It was well articulated, good punch and no hint of bass bleeding into the mids. The mids were shining at the apex and the highs got some body and sounded clear but not a hint of sharpness. This was my the time that the 'Zero' shined the most. I loved this sound. 
At around 100hr mark, I started to feel some mid-bass presence which made the overall tonality a bit warm, the sound was still as awesome as I liked it. 
At around 150hr mark, there was marked mid-bass presence. It was slightly more than my liking. I could not call these balanced anymore. Surprisingly the mids and highs held up quite well. 
At around 250hr mark- Slight more mid-bass presence from the 150hr mark, but almost no audible change. I decided not to burn in any more. 
The shozy zero tends to be a warmer iem with well articulated bass, which has good impact and extend deep. It doesn't have much quantity but do have good quality to it. But there is a mid-bass boost after the burn-in, which gives an overall darker feeling to the sound, which was more prominent when listening to some bass heavy songs like 'Boom Clap' by Charlie XCX, which sounded kinda boring. Also, it felt like the bass reproduction was not fast enough. On slow and moderately fast tracks, the bass does really well accurately portraying the tunes. Really love how these sound while playing Eagles, Hotel California, Taylor Swift and several other pop/classical/acoustic/soft rock musics. But it can not properly handle the fast paced songs which have a lot of bass as well as other istruments playing together. This was specially evident while listening to tracks by Eluveitie, Yellowcard and other hard rock/metal bands. In those cases it can't cope up to the speed and tend to get mixed up together and can sound a bit messy. So, a 7/10 for Bass. 
The mids, a bit thick and very detailed, clearly take the center stage in Zero's performance. The mids seem to surprise me every time I put these in my ear, since the first time till now. The rosewood shelled iems produce the most lifelike mids i've had the chance to try out till now. The string instruments, the piano, guitar riffs are accurately presented and sound beautiful. The The vocals are engaging, very detailed and have an authoritative presence. There's no hint of sibilance, the extension is just perfect in my opinion. Acuostic, classical music sound best with it, pop, soft rock and even some hard rock tracks sound really well too, specially the ones that demand better mid presence. Even in heavy metal songs where the it struggles to keep up with the bass, it does really well focusing the mids and vocals. It's almost like a visceral experiance, an emotional journey. For a 50$ iem, it's unbelievable. 10/10 for mids. 
In comparison with the mids and bass, the highs seem to take a backstage here. They treble is quite flat and sound neutral mostly, it isn't very sharp and lacks some of the sparkle up top & rolls off at around 9-10kHz. Overall experiance is smooth and non-fatiguing, but lacks a bit of excitement. Those who love the V shaped sound would be disappointed. But those who wish for a more comfortable sq for longer listening periods, look no further, the Zero's are here just for you. 6/10 for treble. 
Soundstage and imaging- 
Being a closed back IEM, I have very little expectations with the soundstage and as expected, it was not too narrow, but not too wide either. The instrument seperation took a hit for this reason, specially when a lot of instruments were playing it tended to get a bit messy. When I tried  movies and gaming (CSGO) though, I found that the zeroes provide a really good 2 dimensional sound but not 3 dimensional as it lacked the sense of height. I was clearly able to guess from which direction the enemy was coming from but finding out most of the time that the enemy was actually a level atop or below me. Movies did quite good though. 6/10 from me. 
Isolation and leakage- 
Isolation depends a lot on getting a proper fit and seal, and with the supplied medium sized silicone tips, it was not a problem. as soon as I got the proper seal, I was isolated from the outside world, leaving just me with the music. It completely blocks out almost everything below 60-70 db which includes conversational speech. I could not hear even the guy who sat beside me talking to the phone. Although I could hear the noisy ceiling fan in my room when slow music was playing. Also, I did not notice any sound leakage as my friend sitting beside me did not hear any sound coming out the iems once they were inside my ear canals. 9/10 here. 
 5K1A0045.jpg      f814831e_5K1A6258.jpg
The Fiio EX1 is a open back titanium diaphragm driver priced at 69.99 USD, i've had these for about 7-8 months now. These are extremely good iems at the price point. I've reviewed them here-
The pricing puts both the shozy zero and the fiio ex1 at the same price range catagory (>50$ but <100$) so I thought it would be a fitting comparison. The EX1 has a U-shaped tonality with lots of emphasis on both the ends and slightly recessed mids, whereas the zero has mid bass emphasis with slightly boosted and detailed mids and rolled off trebles. Both iems ran at almost the same volumes on my playback setups, the Zero needing a bit more power (5-10% more) than the EX1. The bass on the EX1 has more quantity and quality, it is faster and a par above the Zeros. The mids are an entirely different story where the Shozy produces more forward, engaging mids, lots of microdetails whereas the EX1 mids are a bit distant and tend to sound metallic in comparison to the Zeros. The detail level is similar to both iems, although purcussion instruments sound just better in the Zeros. The highs in the EX1 are also boosted, has a lot of sparkles and give a sense of airiness the zeros can not offer. But EX1, having treble peeks, is known for getting too sharp specially in treble happy songs and that in turn becomes a hinderence in long term listening. The zeros are much more comfortable for longer listening periods but is a bit less exciting. But overall I would say that the Zeros over a more engaging and emotional listening experiance than the more refined and energetic EX1. 
The EX1 being an open back iem definitely benifit in the soundstage criteria, offering better seperation, imaging and positional audio. But that backfires in the isolation and leakage area. In a quiet room and moderate listening volumes, everyone whos inside would be clearly able to guess the music I am listening to with the EX1. It also lets a lot of outside noise in, so the Zeros get the upperhand here. 
So, if anyone prefers a fun sounding iem with lots of energy and don't mind the openness would like the EX1 whereas those who are looking for a more comfortable, personal listening experiance with mid-emphasis would lean towards the Zeros. 
Shozy, on it's 1st attempt at the IEM industry, has delivered to us a gem of an IEM in the Zero. In spite of not being in my preferred sound signature, these have won me over with its overall presentation. There are the most comfortable and emotionally engaging earphones i've owned so far. The emotional and engaging mids along with the non-aggressive nature is a quality that I can praise time and time again, specially at the price point. There were times when I could not put these off my ears even though I wanted too, these are that good. Also it is perhaps the prettiest iem I have owned till now. I believe with some cosmetic modifications these can be even more attractive and even a bigger bang for the buck than these already are. 9/10 for overall value.

Nice review mate, I think we hear these the same way. I still have to post a review, but I think you nailed it. Nice pictures as well. Is that a camera or a phone camera? Nice either way.

@Sonic Defender thanks man. The pictures were taken with a Canon 7D MII and a 55-250mm lens. Will be waiting for your review. 


100+ Head-Fier
Pros: Good bass liveliness, quite strong clarity, quite even frequency response into the treble, non-agressive presentation.
Cons: Vacuum seal design (driver flex has been heard), no cable cinch.
I was contacted by a Shozy representative and offered to evaluate and honestly review the Zero IEM, after letting it play around 200 hours of music. They were delivered to me free of charge, so keep in mind this potential bias. I will try to be as honest and objective as possible. I own several single dynamic driver IEMs, aswell as a few balanced armature designs.
I tend to prefer metal and rock music, aswell as soundtracks, and 80s music.

The Shozy Zero is a very small, very light-weight IEM. The prominent feature is the Rosewood housing, with what feels like metal nozzles (or maybe plastic, not entirely sure), and with cable strain relief by the housing. Cable has a slightly rubbery feel, with some memory effect. Overall the cable is quite nice, reminds me slightly of a slightly thinner Vsonic GR07 cable, and a transparent cover on it reveals some textures and colors of the internal wires. Straight 3.5 jack also from rosewood, with a slight rubber strain relief. Y-split is also Rosewood, and there is no cable cinch.
When inserted, the Zero creates a seal with your ear canal, meaning its Dynamic driver unit seems to not use/require ventilation. If you move the ear canal through big facial movements, the frequency response changes as the pressure in the ear canal changes. Typically not something you notice in most use cases, and I would imagine that foam tips would avoid this (though I haven't had the chance to try the Zero with foam tips).

My Shozy Zero is a generally bass-leaning, smooth sounding IEM. Depending on tip choice, the sound can be quite sub/bass-heavy, or with some tips a slightly more balanced presentation is possible.
Micro-detailing is perceptually good, thanks to the even frequency response and non-peaky treble. Macrodetail/speed is probably where the biggest giveaway to the low price lies. The bass is quite big and deep, and fairly slow and loose, and slightly boomy-sounding, though that is probably more from the sub-bass emphasis, and the bass generally doesn't really bleed into the mids.
The mids are smooth and even, sitting a few steps behind the sub-bass and bass. The mids are slightly thicker, as opposed to projecting transients forward. This results in a dynamically veiled, slightly warm, inoffensive midrange. Instrument separation and layering is quite good despite this, and something like atmospheric synths can quite clearly be heard even while distorted guitars are taking up room in most of the midrange.
The treble has a certain level of micro-snap, but isn't nearly as dissecting as a balanced armature driver or some dynamic drivers. It seems to saturate fairly quickly in terms of how well it separates dynamically, and using EQ to create a peak around 6-7 KHz where drum transients tend to dominate doesn't really increase the dynamic level as expected, but rather boosts the volume without increasing the aggression of the sound. This again leads to a smooth sound which doesn't really immediately impress with its decay or technical prowess, but also allows you to avoid sudden aggression from music.
The general sound seems to be steadily held at a comfortable level thanks to the, dynamics-wise, smooth presentation, with smooth midrange and treble, and the bass having some depth and heaviness to give a bit of movement to the sound. Layering is quite good considering the smooth dynamics, and the soundstage, while not holographic or 3d for me, has good depth, I suspect the bloomy bass gives the sound in general a slightly longer "release" and fundamental vibration which makes them sound naturally slightly reverberant and roomy, rather than being completely dry like speedier IEMs.
Considering the fairly variable sound of the Zero depending on fit and tips, the above might differ more or less.

Zero Audio Tenore ($40-ish):
Probably the most fitting comparison I can make, since they are both small (possibly both using non-ventilated microdrivers), and both command a fairly similar price point. They both have a fairly similar presentation with withheld dynamics and slightly more distant sounding drums as a result. The Shozy has a much more moving bass however, the Tenore is quite dry and light in comparison. The treble of the Tenore I perceive as slightly more accurate, but the Shozy has slightly better transients there. Ultimately the Tenore also feels more compressed sonically, not quite getting the layering of the Shozy, possibly due to the bass movement and depth of the Shozy.
Vsonic GR07 Classic ($99):
Twice as expensive, the GR07, on a technical level, is entirely in a different league. Drums are not held back or restrained or evened out, they can pierce through anything. The difference in design goals between the Shozy and the GR07 is interesting to hear. Even when using EQ to make the GR07 treble significantly more dark than the Shozy treble, the GR07 still snaps as quick as Bruce Lee in his prime. Also apparent though, is that the bass (along with the general sound) of the GR07 is more armature-like, and just won't bloom with the same gravitas that the Shozy Zero bass does. The Zero, when going back and forth between the two IEMs, definitely is more gentle, more about bringing the tones closer to you, and not nearly so concerned with slapping you in the face with transients as the GR07.
Despite the Shozy Zero being neither my favored sound signature nor presentation (I prefer a bass-lighter sound with strong dynamic separation), I can't really fault it in any area. The design inherently needs a vacuum seal (which I'm not a fan of but foam tips might help with that), and driver flex (a crinkling sound when pressurizing the ear canal while inserting using some tips) has been observed by me aswell. The driver seems to be affected by low or high pressure in the ear canal, which a ventilated design generally won't encounter. The Zero should suit someone who enjoys a non-offensive sound, who doesn't want aggression in the presentation, and who favors a sound that leads quite vibrantly with the fundamental notes of the music.

I wonder if the fact that I wasn't getting the crinkling sound indicates the seal wasn't as tight as I thought and needed to sound their best (or worst if the bass does bloat out at all).
@Sonic Defender: I think it depends on the tips, and the amount of air that the tip allows between the eardrum and the IEM driver. Tips that quickly seal the ear canal even before you start pushing them in to the proper position will put pressure on the fairly big air mass still trapped in the ear canal. Smaller tips you may get almost all the way seated before they seal completely, and thus most air has escaped and not much pressure can be created. For example. :) I've had some big tips that are more prone to creating a bothersome pressure, while others are more forgiving.
I use double flange tips, it makes bass tighter and more balanced. I can't believe it just $60 and it paired very well with cayin n5.


Headphoneus Supremus
Pros: Pleasant non-fatiguing sound signature, somewhat dark with nice detail, and Light (Airy?) Mids favoring female vocals. Value v.s. Price
Cons: L/R markings are difficult to read, somewhat slightly bloated bass, lacking in Sub Bass extension, for some enthusiasts treble may be a tad rolled off
Preamble: I was honored to receive an invitation to join in the Delta test of the pre-production Shozy Zero around April 16th. I received the unit in a plastic baggie along with several tips and was pleasantly surprised how Nice they sounded right OOTB. The review following will give my personal impressions of the Shozy Zero IEM and hopefully do them the justice that they deserve. As this is now the 13th Review of these, At the Risk of becoming redundant, I didn't waste time photographing the Zeros again as most reading this review probably have a Fair Idea of what they look like.
So with no further Ado:

ADDITIONAL DISCLAIMER:  I was approached By SHOZY to take Part in a Delta Test of this new product and was provided a Pre-production Pair in Exchange for my Input and Review.
Specifications:  They are available using the link to the seller(s) posted at the top of the page
Cylindrical wooden body made of rosewood that terminates in a Black Plastic Nozzle with metal wax Screen inside. Also note that the rims of the Nozzles are “Notched” out to reduce overemphasis of  Bass. The cable is the typical 4 wire multicolored wire used on many Asian Products with a Somewhat “sticky” feel to it that I find is diminished with a little Baby Powder applied to it. The cable standoffs bear the only clue as to Right and Left orientation and are not easy to read. The Cables join at a wooden “Y” sans chin slider emblazoned with “Zero” then continue on to a wooden Bodied 3.5 gold plated Plug with “Shozy” inscribed on it in the Same script as the “Y” splitter. All in All Quite a Handsome product and somewhat smaller in stature than I was expecting. I opted for Wide Bore Medium Auvio eartips.
Source Details:  For this particular review I used my Rockboxed  XDuoo X3 (very much improved sound quality) both amped and un-amped through a Fiio E12 Mont Blanc portable amp and a Schiit Audio Vali headphone amp. Line out from source to both amps. My Files are all at Least 320kbps to 96khz high resolution files. I used this source in all comparisons. Note that there were no appreciable differences noted in sound quality using the 2 different amp sources.
Source Material:
The following is a list of songs that I used in this review. Some I use all the time, some less frequently. They all contain some type of frequency, Detail, or EQ that make them suitable for reference.
Note: for Burn In purposes to 200 Hours time, as suggested by the manufacturer, I used a Jlabs Test Track and Vivaldi and Mahler Symphonies on Repeat, Interspersing with some Fairly Bass Heavy Trance music about every 30 Hours or so.

General Sound Quality:
 The Shozy Zero is articulate and fairly neutral tending towards the warm side. They're a full bodied sounding IEM, and have bass even though fairly well balanced. The bass isn’t the tightest but it’s there and in just the right amount, and fairly fast to boot.  The sound is on the smoother side, with a polite if somewhat rolled off treble, a mid-range with quite a nice amount of detail that manages to stay in front of the Bass.  The treble is very good as far as tone, and I find it quite listenable.  Detail retrieval and Placement are exceptional as I can easily locate separate instruments.  It has a somewhat narrow soundstage, but quite a bit of height and depth, this gives the impression of being pretty big sounding nonetheless, the layering is quite good too. Clarity and micro details are above average for an IEM with this warm of a signature.
Bass is very slightly north of neutral and has a slight amount of Bloat evident on some Bass-Heavy material but is still very nice. I find the bass to be quite punchy, and forward without really intruding into the Mids. It does lack in comparison to some IEMs Sub-Bass extension.
The midrange is really quite sweet. The overall balance between the Bass and Midrange is such that it is always in front of the Bass, showing more presence. As noted, I find them towards the light side giving more articulation to female vocals as opposed to male, some would describe this as Airyness. I just don’t think they are as thick in the lower "Male vocal" mid frequency range.
The Highs aren’t harsh, in fact by most accounts they are rolled off, yet they show some sparkle without becoming fatiguing in any way.  The treble may lack for some, but it's not recessed out. I feel the Zero has somewhat of an “L” shape to its EQ. The highs on the Zero don’t really stand out but I find them smooth with enough extension to be enjoyable but not intrusive in any way. This gives the Zero a high listenability factor for me personally
Well, I WAS going to go through a Step by Step LZ-Z03A v.s. the SHOZY, but it would suffice to say they are the Antithesis of Each other. Pretty much equals in detail retrieval, clarity, soundstage placement and layering They are Polar opposites in the Warm VS Bright of their individual signatures. The LZ is leaning on the enhanced Mids/ Bright side with maybe a TAD more bass extension and the SHOZY is just where I like it, Warm and Comfy.
For me Personally, it’s the Shozy Zero by a country mile, Hands Down.
For Build, comfort and Sound versus Value The Shozy ZERO is a winner and pretty much a no Brainer for those looking for Great sound at an attractive price.
Thank You so much Shozy for letting me Participate in this Delta Test.

Nice review, and I tend to hear these quite similar to you, but I do suspect my seal hasn't been as good as it should be so before I do my review I'm going to see about that. Thanks for the brief head to head with the LZ Z03A!


Member of the Trade: Acorn Audio
Pros: Very warm and forward mids, well-extending bass, comfort, aesthetics with real wood, easily driven from portable devices
Cons: Rolled off treble, cable could use more durability, hard to read L/R markings

I am a big fan of overachieving gear of any kind. What I mean by overachieving is the “they sound way too good for the price” factor. This is a highly subjective mindset because the worth of an item is not based primarily on its cost but rather its overall performance, aesthetics and compatibility with the end user. However, some items are just almost “too good to be true” for their price – such as the VE Monk and Monk Plus by Chinese company Venture Electronics which deliver astounding quality for $5, a well-documented fact in the portable audio community online at this point. However, the competitive nature of the audio industry has birthed many a company to try their hand at producing premium sound at a competitive cost.
One of those companies is Shozy, who are based in Hong Kong. A quick browse through their website shows that they have been focused on amplifiers and DACs till now, along with a DAP called the Alien – which is said to have incredible phone-out sound quality at a comparatively low price compared to others in the market. It achieves this, however, by not having a screen – merely a few buttons that are reminiscent of the iPod Shuffle experience from the early 2000s. Shozy has exactly one earbud and one IEM and this is a review of the IEM.
I was provided with the Shozy Zero IEM after being approached by a representative from the company. I was told that I would be given a b-stock model, sent in an envelope with three sizes of tips and no packing or carrying case that the retail model will have.
I was given instructions to burn them in for 200 hours before being given an accurate sense of the sound. I found this to be an unusually long period of burn in time, but I carried out the deed due to an acute curiosity as to whether or not it would achieve anything. Thanks to Shozy for the review model.
Specifications (From Shozy’s Website):
  1. Audiophile quality Litz structure cable with enhanced shielding.
  2. Sensitivity (at 1khz) 94 dB.
  3. Frequency Response: 20 Hz – 18 kHz.
  4. Input connector: 3.5mm / 1/8 inch gold-plated stereo TRS plug.
Initial Impressions:
As I pulled them from the small, padded envelope they arrived in, I was startled by just how small they were. I had scoured their site for photos of the product and I came away with the impression that they were bigger than they actually are. I chose the medium tips, feeling that they give the best seal, and plugged the IEM into my Samsung Galaxy S6. I went straight for some electropop, a genre with prevalence on my phone due to it being good music for commuting – for me anyway. My first two thoughts were that the warm sound signature felt pleasing to my ears and that the mids were not bad at all – to say the least. I listened for a while to gather impressions of the performance and found it to be quite good. They had a fun sound signature that didn’t sound V-shaped. The sub bass extended quite well and the mid bass made EDM and electropop sound punchy and fun. I was strongly reminded of my time with the ZMF Vibro Mk. I and for good reason, but more on that later.
After a few hours, I put them aside at a burn-in station in a corner of my room and forgot about them.
Build and Comfort:
Before I talk about the sound quality and any changes that may or may not have happened as the burn-in process continued, I should note the build quality of these IEMs. As you can see from the photos, it utilizes rosewood on the monitors, the splitter and the 3.5mm jack. I found the latter two to be an interesting design choice, but it does lead to the uniformity of the entire design. The rosewood is a nice dark grain, not quite unlike my acoustic guitars that gives the IEMs a premium look. A nice wood housing can make many high-end components simply gain aesthetical appeal, and I’m glad to say that Shozy did not skimp on that aspect because the rosewood is indeed real and the entire design choice using it does not come across as gimmicky.
As stated before, the monitors are incredibly small. Even with the medium tips, they simply disappear comfortably into my ears. I, personally, found this preferable to oversized monitors that I have seen before – with their plastic or metal casings. However, this also means that the Zero is not the most durable of earphones and thus should be treated with care and respect. Basically, don’t damage the wood folks.
As for the cable, I approve of the colour scheme matching the rest of the unit, but the rubberized and sandpapery traction felt overly synthetic and displeasing to the touch (irony considering the kosher nature of the monitors themselves). I also found it to be a bit thin and would have preferred a thicker and more durable cable for the price. Ultimately, however, the cable did not make any noise when moved and adjusted and was still far, far better than my Zero Audio Carbo Tenore and Zero Audio Carbo Basso cables. There is also no neck adjustment for the Shozy Zero, which is another detraction.
Pictured Left to Right: Shozy Zero, Carbo Tenore and Carbo Basso
Comfort is excellent and I can’t find anything wrong with how long I can wear them. The only people who would have trouble wearing a Shozy Zero for several hours on end are those persons who dislike the feeling and experience of using IEMs in the first place. I especially preferred it to the Carbo Basso, which is extremely thick (with an extremely thin cable) and comparatively uncomfortable.
The left-right markers are in black…on top of black, which makes them a pain to distinguish in anything but the best lighting conditions. I fully understand Shozy not wanting to desecrate the rosewood with the letters “L” and “R,” but I feel that the lettering should have been given a matching reddish-brown tint to make it at least readable while maintaining the overall aesthetic. The Zero’s logo itself is chiseled into the wooden cable splitter, but could have been made a bit bigger and bolder in my opinion. I am in no way arguing for Beats level of brand-shouting, but a little more visibility of the logo would be nice.
The audio jack itself is straight, which works for my phone as the 3.5mm connection is on the bottom – but I can see it being an annoyance for those who have DAPs and phones with it on the top. Again, I can somewhat understand why a straight connector was chosen – so that Shozy could add more of the beautiful rosewood somewhere. The beauty does come with a cost however in this regard, if this sort of thing is a hindrance to you.
The above comparison to the ZMF Vibro Mk. I made more sense to me the more I listened to the Shozy Zero. For those who do not know, the Vibro is a mids and bass centric pair of headphones that has rolled off highs.
The bass is not very tight by any means, but it is very filling and has good extension into the sub-bass area. The mid-bass is very clear and present and has a delicate balancing act with the mids as to not drown them out. I would actually consider the bass as treading the line between chaos and discipline carefully. Its strength at this is musical genre-dependent.
The mids were the biggest surprise to me as they sound really smooth. Vocals sound quite warm with a slightly forward tilt. The mid-bass and mids combine with well-recorded acoustic guitars to lend a quite authentic impact to the strumming and plucking. The biggest strength of the Zero’s tuning was its ability to give body to the vocals of a song with a large amount of instrument layering both in electronic and acoustic genres. Vocal harmonies were quite easily picked out as separation is robust and detailed. With the quality of bass that these IEMs have, I was surprised and grateful that the mids did not sound muddy or rolled off, as was the case with the Carbo Basso. I preferred the coloured and warm mids of the Zero to even my previous favourite IEMs, the Carbo Tenore, as they sounded lusher to my ears rather than incredibly neutral.
The treble is what reminded me the most of the ZMF Vibro Mk. I initially as it felt a noticeable degree rolled off. Unlike the sibilant V-shape of the Carbo Basso or the neutral presentation of the Carbo Tenore, the Zero halts the extension past a certain point to provide a warmer experience that is never sibilant. This did, initially, prove a little problematic with certain genres such as classic rock and orchestral music, but the highs definitely opened up by fifty hours of burn-in. Interestingly, I did not hear a difference past fifty hours, but continued to run them through my burn-in station regardless. I am confident that I now hear these IEMs at their fullest potential, and they sound good.
The treble is what denies these earphones from being classified as all-rounders to me, so if that is a consideration for the reader then the Carbo Tenore wins out. The listening experience is heavily dependent on the production quality of the audio played through the Zeros. At one point, you’ll hear a song where some instrumentation struggles to be heard, but at other times all will be right with what you hear. Hello by Adele is one such song that sounds great on these IEMs as her voice rings out clearly in the mix while the backing track retains a dramatic and cinematic sound due to the low-end being so well represented.
The soundstage is quite vast, comparable to the Carbo Tenore and far, far better than the Carbo Basso. Recordings with spread out instrumentation, as well as “3D” positional audio and ASMR will be well served by the Shozy Zero.
I am comfortable in saying that these are very easily driven earphones to the point where I would recommend not using an amp at all. For the purposes of testing, I hooked it up to my Schiit Gungnir  and Cavalli Liquid Carbon, but found that it became way too warm. Switching the amp to the transparent Schiit Magni was a better match, but still unnecessary. It sounded better from my Samsung Galaxy S6 honestly. I don’t have a DAP at my disposal currently but once I do, I will update this section of the review.
While writing this, I realize just how few “neutral” earphones and headphones I’ve actually had the chance to review. The Shozy Zero is another in the line of “fun” headphones that I’ve had that don’t try to, simply put, do it all. This makes a product like this harder to gauge so I just go by what I enjoy in music listening and apply it to my findings. Your mileage will doubtlessly vary, which makes it difficult to recommend based on written descriptions alone. That and the large amount of recommended burn-in time makes it so these are earphones I would highly recommend you finding some way to demo – unless you are into warm and bassy sound signatures by default.
For my purposes, these IEMs do well and I will be using these out in public because they are:
  1. Easily driven and not picky about sources.
  2. A good pairing with electropop and other high-energy genres of music that I primarily listen to in public.
  3. They look good.
  4. Comfortable and provide a great seal.
  5. The bass and lower mid emphasis is good for commuting in noisy conditions. This is the opposite effect of the ATH M-50X that I used to have, that would become tinny and sibilant outdoors. This never changes in such a way and that is a big plus to me.
  6. They combine aspects of the Carbo Tenore and Carbo Basso  – taking the strengths of the former and losing the deficiencies of the latter.
Do they sound like something in the several hundred dollar range? I can’t say because I have not heard IEMs of that pricing in recent years. Do they sound like they are worth more than $60? Yes. There is a refinement to the mids that is something to be appreciated. However, these do not fall into the range of critical listening. They are bassy, musically tuned and coloured IEMs and should be approached and appreciated as such
Song Impressions (lossless FLAC files in at least 16/44.1):
Abba - Gimme! Gimme! Gimme! (A Man After Midnight)
Does far better than the Carbo Basso at presenting the driving low-end of the beat without sacrificing the vocal impact. The bass guitar and bass synth-line are the clear focus while listening on these IEMs.
Aerosmith – Dream On (2012 Remaster)
Very warm with really good separation in the intro, with both guitars ringing clearly alongside the distant sounding string section. Steven Tyler’s vocals have a lot of body to them while the backing beat has a fair amount of discipline in its bassy yet refined presentation.
a-ha – Take On Me
A punchy piece of 80s synthpop being represented well, especially by the soundstage due to the swirling synth section.
Alan Parson’s Project – Sirius/Eye In The Sky (2005 SACD)
What I find most interesting about listening to these tracks on the Zero is just how detailed the guitar work can sound over a backing track that feels a bit too warm - especially the acoustic guitar in Eye in the Sky. While these recordings are incredibly produced, they don’t play to the Zero’s strengths.
ATB – Move On (Feat. JanSoon)
It doesn’t dive as deep with the sub-bass as the likes of a Fostex TH-X00 obviously, but still a decent presentation of electronic music.
Billy Joel – We Didn’t Start the Fire
A pleasurable and punchy listen, with the melodies spread out the vast soundstage. The vocal harmonies in the chorus ring out clearly.
Blink-182 – I Miss You
A nice representation of the acoustic guitar sound on both channels. The rolled-off treble tames Tom’s vocal quite a bit but in a manner that doesn’t detract from the song.
Childish Gambino – Heartbeat
A great match for the Zero. Donald Glover’s tortured rap and vocals ring out as the hectic backing track is compartmentalized while being well represented. The cinematic quality of the song is also well-served by the soundstage. The repeating piano melody sounds even more haunting than it would on a neutral pair of earphones.
Chris Isaak – Wicked Game
The gently-strummed guitars sound lifelike and well-separated. Isaak’s crooning vocal has even more body behind it thanks to the sound signature.
Clint Mansell – Lux Aeterna
This production plays to the Zero’s strengths again as it utilizes the soundstage and low-end on string section to add to the dramatic nature of the composition. The violins ring out clearly without sounding sibilant.
Coldplay – Clocks
A great match. Chris Martin’s vocal is encompassed by a warm and pleasing wall-of-sound as the uniform beat drives on. Vocal harmonies are well represented with the piano riff taking center-stage of the entire song clearly. 
Ellie Goulding – Lights
This is an example of a song that actually benefits from the Zero over a more neutral IEM. Goulding’s vocals in this track are quite thin in the upper-register, but the chorus is aided by these IEMs bringing forward her lower-note harmonization – leading to the overall sound feeling fuller.
Emerson, Lake & Palmer – From the Beginning
The acoustic guitar has a lot more body to the sound than some other headphones I’ve listened to this track with. The bass guitar is louder than those other headphones too. The separation of instruments is impressively well-done. The vocal volume feels a little lowered however.
Eminem – Without Me
The snare has a bit of a thud to it, but the rest of the track sounds as it should. The driving bassline does not clash with Eminem’s rap and the organ motif rings out in the mix.
Fleetwood Mac – Dreams
The mids of the Zero do this song immense justice. The vocals sound lifelike and well separated (the chorus has four vocal lines harmonized) while the acoustic guitar sounds lifelike. The bassline does not drown out the delicate balance of the rest of the song.
Kanye West – Jesus Walks
The backing track sounds bombastic but Kanye’s vocals feel slightly lowered in the mix.
Kavinsky – Nightcall
A lot of sibilance in this track is tamed by the Zero without taking away from the impact of the snare or female vocals.
Lana Del Ray – Summertime Sadness
Vocals ring out clearly with plenty of body while the cinematic and dramatic backing track does not clash with them. Sounds as the song should. Very good synergy.
Led Zeppelin – Achilles’ Last Stand (2015 Deluxe Edition – HDTracks)
I was a bit apprehensive going into this song because it did so poorly on my TH-X00, but those fears were alleviated once it kicked in. The soundstage helps this song immensely, which is the major advantage this has over the Fostex, as the guitar tracks are far to the sides while the bass and drums take center-stage. Everything rang out cleanly and Plant’s vocal was unencumbered.
Linkin Park – Breaking the Habit
A slight clash here because the frantic and heavily digital sounding backing track fights with the vocals a bit. Still a good listen.
Lorde – Royals
This more laid-back track benefits from the sound signature and soundstage. The sub-bass rings out without entering the region of the heavily-harmonized vocals.
Machine Head – Davidian
The song retains the power it absolutely should have, with the guitars having a warm sound to them.
M83 – Midnight City
This song mixes shoegazing elements with electronica/house. Probably one of the best pairings of IEM and song that I’ve heard as the vocals feel beautifully ethereal but maintain the body and clarity on top of the wall-of-sound backing track that absolutely pulls no punches. The only time anything feels drowned out, it is the saxophone solo at the end.
Pendulum – Set Me on Fire
The drop’s lower-end has the impact, but the upper ranges have detail that gets drowned out by the pounding bass. Not the best match.
Queen – Bohemian Rhapsody
Vast soundstage? Check.
Good vocal representation with the harmonies? Check.
So you just know the middle section is going to sound great, and it does. Interestingly, the tone of the distorted guitar in the last section benefits from the warmth too.
Queen – Another One Bites the Dust
Superb balance across all ranges. The vocals and guitars sound the most impressive, particularly Brian May’s clean-strummed lines.
Rage Against the Machine – Killing in the Name of (2012 20th Anniversary Edition Remaster)
Zack’s vocal sounds good but the backing track feels louder than normal. Interestingly, it doesn’t bleed into the vocal. Despite this, the attitude and power (especially in the final refrain) is present and accounted for.
Ramin Djawadi – Game of Thrones Theme Song
Overly warm, but very good representation of the now classic theme song. I feel this has more to do with the production than the Zero however.
Slipknot – Wait and Bleed
I wasn’t able to listen to Slipknot out in public before the Zero because my other IEMs didn’t do the hectic production justice without losing out on the impact. I’m glad to say that this has changed.
Thanks for stopping by. You can follow me at:

I believe that "We didn't start the fire" was sung by Billy Joel not Billy Idol.
Thanks for the review.
Treble less bright and hard.
The mid and bass are nice.
Sounds like the IEMs I picked up strangely. Only differences I see is that the ones I have seem spacious / wide soundstage.


500+ Head-Fier
Pros: Smooth signature with no sibilance or strange mids a lot of "top IEMs" have
Cons: The cable is maybe the weak spot. Treble is slightly rolled off
Before I start, I want to thank the representative from Shozy for giving me an opportunity to review the Zero free of charge in exchange for a honest, unbiased review. 
In my opinion I want to say that I had not much hope when I was approached because Shozy is very terse with specifics on the IEM. When I got it from him when he was in Singapore he told me I will really like it and I should give my opinions after 200 hours of burn in. That's waaay too long so here's my opinion after spending a week (and getting into trouble for having my IEM on while working which is unfortunate and I don't understand why that's a problem) and I will do a separate review when 200 hour mark arrives.
As he passed it onto me in person there was no need to have a box or anything or bubble wrap so I don't know how the package looks like but I will assume it's fairly decent.
It comes with a set of S/M/L eartips that seems lifted from a IE800. It was impossible to insert into the IEM but I will get to it later
The wood machining felt flawless when I went over it with my finger but perhaps not so flat when I photographed it. Okay, big deal, no wood is perfectly flat.
Or the later images might have been out of focus. I have my extreme wide bore tips out for this IEM and it's a better match for this IEM as it's way easier to install but it's dependent on a wide bore IEM as it's bore is more than 5mm or so.
The wood used for the Y-split and the connector is just fantastic and the product logo plus the brand is actually engraved not just etched/padprinted
Marvelous. So it's not lacquered and then polished for days but it looks like rosewood that's had a bit of stain on it.
Unfortunately the cable isn't that good and it's actually very similar to the cables that come with a lot of chinese IEMs but slightly thinner with a tinge of lower microphonics but it's still there even when worn over ear which for some reason no normal IEM will stay intact over my ears and to compound the problem the Y split is positioned a tinge too high so the cable keeps rubbing my face when worn normally. The cable also has memory and is a challenge when I first took it out of the package to reveal that it's a zig zag fold. It's still not straight a week later unfortunately.
There is a notch at the bottom which I forgot the reason of its existence.
Judging from the size of the IEM I am estimating the driver to be 6-7mm but Shozy is keeping mum on the size of the driver. It is still fairly small and I can fit the whole IEM into my ears but of course, I found that S size tips have to be used to go all the way in my canals and so is my ear that's why I like just microdrivers. 
The Titan 1 in comparison felt like a great big slab of steel in my ears.
Isolation is fairly fantastic and there are no ports on the IEM so it's completely closed but later on you will be surprised.
Before I am to give my impressions on the sound, I was pretty surprised it's a 60USD IEM.
So, sonic impressions.

The bass is stellar but not as tight as I would prefer my bass. (My reference is a 1990s 8" sub in a sealed enclosure) It does have a bit of a punch and thankfully it doesn't have rumble that I feel rather spoils the soundstage.
Extension wise it does as well as my reference sub. Which is to say it really hits hard down and in a controlled fashion too but that's the least of my concerns as bass is easy to pull off, mids and treble aren't.
Which brings me on to treble and mids, 
Mids are neither too forward nor rearward and I like treble and bass to take a backseat to the mids which are beautiful on this IEM with having all the timbre that shows through female voices even deep smooth female voices like Sonoda Umi in Datte Datte Amujou (Suzuko Mimori) and details are great for female voices.
It falls back a bit on male voices when I switch my material to Metallica's Hell And Back or Megadeth's 13. There's a bit of a raised midbass so there's a slight cloudy sound when moving from bass to mids
Treble is slightly rolled off on the Zero but there is no sibilance that even some top IEMs exhibit and therefore I can hear Ayase Eli's beautiful high-mid centric voice without cringing in Arifureta Kanashimi No Hate that often exposes plenty of IEMs sibilance. Fuyu ga kureta yokan sounds like the description of heaven when I listen to that song with the Zero.
A lot of IEMs fail for me that they have either really dull treble (KSE1500 : Great mids and details but dull treble and punch-less bass as with as all estats) but the KZ S3 despite costing 6 bucks is a worthy adversary for even this as that comes very close to the Shozy Zero in details.
Oh and soundstage. The Zero delivers on soundstage and separation which I'm pleased is surprisingly having realized it's a sealed driver as it has a special sort of reverbation that the wood enclosure provides as opposed to metal of my two other top IEMs : The joyroom E107 and the KZ S3.
Although I like the other two a lot and are a whole lot cheaper this is still well worth 60USD they are asking for. It easily shames the DUNU Titan 1 and the FLC8.
If you have questions on my review ask them in the comments thanks. Thank you again to the rep. You know who you are

I found this confusing. Does the KZ S3 rival Zero in details? 
Yes it does, surprisingly.
