Glad you enjoyed it 
Hi all, it’s my first post here, though I’d share my thoughts on the Defiant. There’s already many great reviews, so I’ll just share my condensed thoughts. Mr. SushiiFi’s review just above is already so good.
Build & Fit
Although I generally don’t pay all that much attention to looks, these are something special. The shells are a nice soft black, the rainbow faceplates are gorgeous, and the cable just fits the aesthetic very nicely. Looks-wise, it’s one of my favourite cables, and it’s modular, comfortable, and has no microphonics to boot. These IEMs just look great for the asking price, although they might be a bit extra to wear in the library or in the supermarket. The other available colour, jade, does not seem appealing to me personally, but I haven’t seen it in the flesh.
Comfort-wise, they’re pretty good. The resin of the shell feels very good to the touch, better than Aful Explorers, and the shell in general is medium-sized. My only complaint with the comfort is the nozzle diameter — 6.3mm. I wish chi-fi would focus a bit more on comfort, I’m not sure why they keep sticking with these big nozzles when Western companies usually go for 5.5mm or smaller. 6.3mm should be doable for most people, though. The build in general just feels very solid and premium, I like it a lot.
Sound
In the sound department as well, I’m impressed. Compared to Harman, there’s a present but not exaggerated sub-bass, some mid-bass warmth, a bit of 1.5k energy, slightly recessed upper mids, a nice 8k presence boost, and a hefty amount of upper air. In a word, very well balanced. It doesn’t attempt to follow either Harman or JM1; it does its own thing, and it pays off. However, for my own personal taste, the air region is just a bit too much. I prefer a rolled-off upper treble, which leads to a more relaxed listening experience, at the cost of lesser perceived technicalities. I EQ the upper treble down, as my prefered signature is what people call ‘dark,’ but I think most people will very much enjoy this present 12-14k region. It reminds me somewhat of how 64Audio tunes their upper treble — it really adds a great sense of clarity.
Comparison
The Defiant fares very well against my two other favourites at this price point, the Aful Explorer and the Sennheiser IE200.
-
vs. Aful Explorer: The Explorer is a favourite of mine since it came out. The build is decent, the fit is good thanks to the small nozzle, and the sound is quite uniquely warm and very easy to listen to. I don’t think anyone would find the Explorers harsh in any way. However, the Explorer can sometimes disappoint with their lack of clarity and technicality. The Defiant is more balanced, clear, and technical while still keeping much of what makes the Explorer great — an easy-to-listen-to and engaging sound. They’re actually not far apart in tuning philosophy, with the most notable differences being the Explorer’s warmer 300- 600 Hz region and its strong treble roll-off. If I had to choose between these two, it would have to be the Juzear Defiant. The clarity and detail are just better, and the build quality and looks are likewise more to my liking. That’s not to say the Explorers are not worth it anymore. For anyone prioritising an ultra-chill sound you can listen to for hours on end, the Explorer is still one of the best you can get. I just think the Defiant is more balanced and a better value.
-
vs. Sennheiser IE200: The IE200 is still very much worth it for mainly one thing: its exceedingly comfortable fit. They’re more comfortable in all scenarios — you can even side-sleep with these. Not to say the Defiants are particularly uncomfortable, but in a direct comparison, the Sennheisers just feel like they’re barely there. Sound-wise, they are (again) not too dissimilar, with the main difference being the IE200’s slightly spicier treble and lesser sub-bass (which you can boost with the tape mod if more is needed). Yet the Defiant does sound just a bit cleaner, more technical, and more engaging, plus, the looks and build are miles ahead of the IE200’s uninspiring (but supremely comfortable) shell. Both are worth the asking price, it just depends on whether you prioritise fit or sound.
-
vs planars: Planars are very popular and a great choice at this price point as well. However, I won’t be the one to do a comparison on this as I just generally haven’t quite liked planars. Great detail and transients, yes, but they seem to generally lack body, weight, annd musicality, even when EQ’ed. I can never get them to sound quite to my liking. I’d pick Defiant over planars any day.
In short
Needless to say, I think the Juzear Defiant is great value. Beautiful shells, beautiful cable, beautiful sound, for a very competitive price. It’s definitely worth getting, granted you have no problem with either the medium-large nozzle or the slightly accentuated upper treble.
Cheers, Kuki

Being a reviewer I try to give my subjective opinions on iems, in the hobby at the moment 95% of iems released at the moment are good so the differences between great iems and good iems is all about the nuances. All reviews are based on a single point in time for the reviewer next week an iem can come along and make a mockery of your previous judgement.
I’d just like to say upfront I believe we are all biased when giving our subjective thoughts about IEMs be it a particular type of signature that works with our music library or how an IEM looks and feels in our ears. On the subject of ears everyone’s ear anatomy is different and this effects fit and seal which in turn effects the perception of bass response so I recommend finding the right ear tips that suit your ears to get the best of any IEM.The Juzear 41T, which I bought for full asking price, introduced me to the brand with a bang! So I thought it was time to see what else they had to offer and see if lightning could strike in the same place twice. So I bought the 61T and was slightly disappointed there was something not quite right with the treble tone. Now the 61T is loved by many so it’s a subjective. When Hifigo.com Contacted me and asked if I’d like to review the Zeos/Juzear Defiant Collaboration iem I accepted with interest. Boy am I pleased I did.DisclaimerHifi Go was kind enough to send me a sample of the Juzear Defiant to review. I am not affiliated with Hifi Go and of course was not asked for any copy checking before publishing, they are seeing this the same time as you. All pictures taken be me or taken from the Hifigo.com website. ALL opinions shared in this review are my subjective thoughts.Make sure to research any iem before you buy!

Back to me.The Defiant are very well constructed of resin with beautiful faceplates (see photos) a medium sized shell that fit my ears very comfortably for hours on end.The included ear tips didn’t really work with my ears seal wise so I ended up using Divinis Velvet wide bore large they are a large bore tip which worked well, Standard Dinius Velvets also worked well but they slightly softened the dynamics. The included cable is very nice a multicoloured cable that matches the Rainbow varient of the Defiant with interchangeable terminations 3.5mm and 4.4mm I used this cable for evaluation purposes.
What do they sound like?
Around the hifi forums I’ve heard the description “Fun” in relation to this IEM, to me, fun means the iem I reach for, when I want to really enjoy my music. Something that releases the full scope of what the artist created in the studio. For a $99 iem the Defiant certainly does that Placing you in the music,the Defiant is w Signature. the bass is textured, dynamic and layered, digging out details on songs. Hybrids can have coherence issues the Defiant sounds like a single driver no trace of Ba timbre just everything working together as one.
Vocals don’t take a step back they are there front and centre with instruments placed exactly where they should be showing impressive depth to the stage with natural unforced width for the price . What do I mean by unforced width? Some IEMs give an impression of super wide stage which sounds unnatural throwing instrument placement off The mids are natural and organic slightly warm with just enough edge to add excitement to vocals and guitars causing me to be drawn into the music, A very engaging musical experience. The Transition from upper mids to lower treble is smooth completely sibilance free, even with Whitesnake’s Still of the night, a song that is the ultimate sibilance test for any IEM.
While the overall signature is slightly dark there’s still lots of detail. The upper treble has a pleasing amount of air and sparkle, without straying into fatigue levels.The timbre of drums, strings, guitars and brass instruments is natural. Vocals both male and female are reproduced with enough detail and nuance, if a voice has gravel its there . Pure female vocals like Montserrat Caballé are imbued with emotion and sweet rounded clarity making an overall very satisfying vocals experience. The sound signature as a whole is of big bass with clear clean mids with a little edge and smooth treble, an overall holographic feeling of immersion in the music.
When I’m evaluating IEMs I have a play list of roughly 100 songs of mixed genres. With the Juzear Defiant found myself listening to songs then hitting pause to go find the album to listen to it in its entirety just loosing myself in the music. I found they worked across most genres both smooth and aggressive.
Lorde - Royals
Royals with its throbbing and droning subass was vibrating my head like being close to floor standing speaker her crystalline voice dancing sibilance free above just magnificent!
Muse - 2nd Law album sounded Immensely grandiose with thunderous bass the guitars and vocals cutting through with excellent timbre and overall natural presentation.
JONI Mitchell - Blue was a lovely intimate rendition the acoustic guitar particularly sounding detailed with the strings resonances from pluck to the decaying of the notes perfect. Joni’s vocals can sound a bit shrill on lesser iems not here the roundness to her upper register was very pleasing.
Steely Dan’s - Aja, one of the best produced albums in my opinion was just perfect, hi-hats and cymbals were natural with excellent decay staging was good with height, depth and width enabling me to pick out each instrument with precision.
Peter Gabriel - live album with the New Blood Orchestra. The full orchestra reproduced with amazing clarity and separation really placing me front and centre of the stage with strings floating around outside my head Gabriel’s voice intimate detailed always perfectly placed.
Lady Black Bird - Blackbird the subtleties of the interplay between vocals and instruments are played to such a high standard that it became intoxicating the space around each component of the song really placed me in the room. Another example of listening to one song leading me to put the whole album on. Black acid Soul is superb Acid jazz/soul mix produced and mastered to perfection and the Defiant really makes the most of it.
Iron Maiden -Rhyme of the ancient Mariner - boy the dynamics of this track are amazing and are reproduced with pin point accuracy , I did not perceive any congestion in the guitars, bass and drums Bruce’s vocals were on point and unveiled just good headbanging fun
The Defiant is very easy to drive and I had no issues using them with Daps, Dongles even with my Sony Xperia 1 mk4 phone using the 3.5mm headphone jack.They pretty much sounded good with all my sources, but they really came alive with a good source especially with the Sony Nw-WM1A where the synergy was strong. When using brighter sources they still sound good just slightly less engaging.
This is not an iem that needs an expensive source but it does scale impressively. When used with the Onix Aplha and my phone I was in heaven it was such a lovely analogue hifi rendering of my music I listened till the battery drained out of my phone.
I’m not a fan of analytical sounding IEMs that force details into your ears like a photograph with HDR and sharpening set at max a decidedly digital representation. I’m more Vinyl on a turntable, Leica manual focus, sumptuous colours on kodak colour gold film, kinda guy, where if you look really close all the details are there but it’s the whole image you appreciate rather than just how sharp it is. The Defiant gives me this feeling no matter which source I use.Sources used:Fiio M21 Sony Nw-WM1AHiBy R6 111HiBy R4 Evangelion HiBy RS2CAYIN N3UltraOnix Alpha FIIO BTR17
Comparisons to other IEMsfor Comparison I’m using the Juzear 41T and 61T.
The 61T has a different tuning, the bass is as quick the bass quantity is similar, with less texture and detail the Defiant sounds more “full”. The mids on the Dfiant are sweeter with just that extra level of detail, the sense of engagement that is lacking in the 61T the treble is more coherent and the timbre is more correct to my ears, less “apart” from the mids with more air, a more holographic experience. The decay of cymbals and hi-hats are better represented with Defiant.
My next comparison is the 41T. the 41T has one more ba and is recognised as a superior Hybrid at its price. While having less bass the overall experience is very similar with the Defiant. The Difiant is a touch more fun/engaging than the 41T when played at loud volume the Difiant pulls ahead holding together with more authority now Considering the price point of the Defiant its a resounding win for the Defiant
Conclusion
I might seem over effusive about the Defiant spouting hyperbole but these iems took me on an emotional Rollercoaster in a similar way the 41T did. While having a slightly different sound signature I would argue that Zeos and Juzear have pulled a rabbit out of a hat giving this kind of performance at the $99 is commendable and quite the market disruption. Another hearty recommendation from me!

So glad everyone is enjoying Defiant and its tuning. Thank you everyone who’s posting reviews here and everywhere else.
I can’t wait for the new cable color release, I’m calling it gunmetal bronze. It should come default with the green face units and I’m trying to see if they’ll sell it separately as a variant of the flare cable.
Also keep an eye out, I’m trying to get the flare sold with dual 3.5mm connectors so you could use it for headphones.
The set I modified.

If they sell the bronze cable separately please for the love of God get them to do the 3.5 version as well!!!
Where can I buy such a beautiful iem stand?
