CCZ Coffee Bean in Ear Monitor, Immersive Bass Sound Wired in Ear Headphones, HiFi iem with 1DD Dynamic Driver Detachable Cable for Singers, Musicians, Stage, Drummer, Church (Without mic, Brown)

Just got these today, and they are superb! I was excited to try them out as I've enjoyed similar headphones (KZ ZST, Tenmak Pro, etc.). I've been looking for a new pair and these were a good price, and they look quite nice. Most importantly, these are COMFORTABLE! Lots of IEM-style headphones just fit weird and can be a bit uncomfortable, but these fit so naturally. I like them better than any other IEM I've tried for fit. The smaller tips also fit my girlfriend's extremely small ears, and she thinks they're super comfortable, too! I've attached a photo showing these in a very small ear, and we were both surprised that they fit her small ears so well!As far as the sound goes, they sound very natural! Slight "V" shape, but not overly emphasized. The treble is clear and not fatiguing at all. I'm really sensitive to treble and these don't have sharp treble for me. The bass is emphasized but not too much. It's very tasteful and just the right amount. I have some really big bass cannon over ear headphones, and these compete for bass quality, but they are not the same quantity, these being more tastefully tuned closer to neutral, but still with some emphasis.These IEMs sound great with all genres, they do great with hip-hop, pop, and rock. My favorite thing about them is they are not harsh or fatiguing, but still sound "fun." I'm so glad I bought these!

Up until a few years ago, I was used to paying several hundred dollars for earphones from brands like Shure, Etymotic Research, Ultimate Ears, etc. Replacing cables or the earphones themselves was always very expensive. Then I discovered the world of Chinese earphones, particularly KZ. Overall, I've found that both the sound and build quality tend to be very competitive with the big guys but at a fraction of the price.With the ZSTX, KZ is iterating on their long line of hybrid earphones with the Dynamic + 30095 BA driver combination. Outside of the original ZS10, I've been universally pleased with all KZ earphones I've heard. It would be hard for me to say that the ZSTX is clearly better than prior iterations, because they share a lot of characteristics in sound signature and build. But what I can say is it seems to offer a slightly punchier bass and they've done a really good job at taming those highs that people used to complain about on older models.Overall, the ZSTX is as an excellent earphone that ticks off all the boxes with great sound, solid build, comfortable fit, replaceable cable, and it costs a fraction of what they could be charging for it.

I've owned a lot of lower-end earbud microphones over the years, and the sound quality of these blows all others in this price range out of the water. Sure they may not be as bass heavy as the popular Sony earbuds, but the bass is still there and present and punchy. I did turn on my iPhone 11's Music EQ bass booster in the settings, just because I'm used to more bass, but overall everything sounds significantly better than any other earbud in this class. I own a pair of Airpods Pro too, and while nothing is as immersive as Spatial Audio on those, when I re-listened to a QCode story podcast named Carrier, which has incredibly immersive audio, these buds waaaaay surpassed in immersion than anything I've heard outside of Spatial Audio.Extra bonus points for a design that allows you to lie down on your side without discomfort to the ear, while also providing better noise isolation. And for a very decent quality microphone.My only complaint is I'm not a fan of this type of twisty cable. It's messy looking and a little annoying to work with, especially because I like to loop and wrap the cable manually in a way that doesn't tangle, and it's just not an easy cable to work with.Oh, and I have very large earholes, so no default eartips provided are usually big enough. I use the 11mm ones that come with the "Sunmns 6 Pairs Silicone Eartips" that you can get here on Amazon, and they fit great on these headphones.

KZ ZSTX is what KZ calls in updated version of the ZST but really these IEMs are playing their own game. While the build and fit are identical, the ZTSX cable is SO much better than the ZST cable, and the sound has evolved enormously. The cable has the newer iteration of KZs molded ear wrap thing. You don't ever have to remold or stretch or crimp the thing it just sits on your ear perfectly and always remembers it's shape. The braided cable (which KZ have been adding to all their newer IEMs) is a huge upgrade and honestly I'm surprised to see a cable this nice on a IEM this price. The mic performs great! No issues there. The main driver housing is the same shape as the ZST and for me it's KZ's best shaped IEM for my ear. I've worn these for multiple days straight for 7+ hour listening sessions during work without taking them out and do not experience any fatigue or pain whatsoever. Everyone's ear is different, but these things like my ears.As for the sound, when compared to the original ZST, the bass is more extended, the mids are smoother, and the highs are more extended as well. The signature is a bit more scooped than the ZST, so if you thought the ZST was a bit mid heavy, you'll prefer the ZSTX. That said, the ZST are more comparable to the KZ AS10, which with their extended low and high range are again playing a different game than the ZST.I'm super happy with these pair and would recommend them as an upgrade from ZST.

Firstly it is very well constructed, from the cable to the casing and fit.It fits well with good isolation, but it's not the most comfortable eartip or casing design for me. But it's good enough.The sound stage and detail is incredible, likely due to the large casing and 1BA+1DD design.However due to this design, it seems as though it can't represent the fully frequency spectrum equally, meaning that you're left with this VERY V shaped sound which if you're sub-bass sensitive will make you uncomfortable. I've tried fixing this with an equaliser and it gets close, but in my opinion that's always an unideal solution that won't fully utilise the hardware capabilities, since it was designed around this V shaped signature.I think a single dynamic driver solution like the Sony MH755 or Tin T2 or Blon 03 would be better at this price point vs multidriver hybrids like this ZST X or its KZ, QKZ and CCA chifi cousins.If you prefer tonality (more neutral sound signature) vs detail then I would recommend one of the 3 single driver earphones I've listed above. If you don't have much experience with audio gear and love boomy bass then go ahead and buy the ZST X, but if you do then you'd be better off buying directly from AliExpress where you can find the higher tier KZ/QKZ/CCA models like the KZ ZS10 Pro or CCA C10 which have many more dynamic-drivers/balanced-armetures (DD/BA).

I walked into the sea on holiday, I forgor 💀 they were in my pocket - walked out after I was hip deep, and left it on my beach blanket to dry. Later I left it on my room's radiator, and finally plugged them into my phone to see if it worked.Results: Dolby Atmos turned on which meant it was receiving power and signal. Audio quality was untouched.In terms of the earphones: a great pair which allowed me to hear instruments and vocals I usually wouldn't hear.Comfort: it's minor, but the left ear bud slips out sometimes, but if I give it a gentle refit it usually doesn't move at all.Sounds stage: yes, very good.Microphone: whilst walking and having the mic rest on me, (as a quiet person) it would usually be fine for the caller apparently (no need to put it up to your lips).Total length: about 120cm (estimate because I'm 190cm).

Honestly these IEM's are really really good and that is not considering the price either. They have crystal clear mids nice and sharp highs and deep punchy bass which doesn't interfere with the mids keeping the whole sound stage nice and wide which is very unusual for in ear monitors (they usually have a more closed feel) but no these have excellent sound stage which makes listening to things like the witcher 3 sound track sound amazing but the extra bass makes them also equally amazing for listening to artists like juice wrld or x. Overall these IEMs really suprised me on how good they actually are I only bought these just for something compact to game with and they ended up replacing my headphones. Would definitely recommend to anyone audiophile or not.

Wow, these are phenomenal for the price. They are a comfortable fit and sound really good. I have been using them for conference calls whilst working from home and the sound is great.The only very minor point, is that it could do a small moveable sleeve on the cable to tighter the fit at the back of the head. However, I have improved with a very small tyre wrap which works fine.

Honestly, I'm blown away by these. I have had custom moulded IEMs for many years - all £400-500+ and these rival them, especially the low-end. This is my second set after the first became faulty after a year...who cares!? I'd happily have a shelf life of 1 year on these at this price compared to my custom ones! I've put them to the test on stages in front of 1000's without a single problem - apart from the judging attitudes of other musos...
