This adds wireless convenience to IEMs. Paired it with KZ Castor Pro.
ANC : 3/5
it is an added plus but people using IEM do not usually care about ANC. The passive NC depends on the IEM itself.
Sound quality: 4.5/5
With LDAC support, works pretty good with supported devices. I even tried it with Iphone, works really good. Most normal people wont feel any difference over wired. Audiphiles may feel subtle loss of details. But thats what you compromise for convenience. Gain may seem a bit low compared to a DAC+IEM setup but 70-80% volume is sufficiently loud. The audio tone is neutral and balanced
Comfort: 4.5/5 As comfortable as the IEM itself. Gives a Open Wireless earphone feel in terms of comfort. I have wore it over 8-9 hours intermittently playing songs - didnt feel any bulk.
Case: 1/5 Extremely bulky. Forget about keeping in the pockets when you decide to buy this. But treat it like a IEM case. The feel is plasticky and not premium. The adapter themselves feel premium but not the case.
Battery: 4/5 Decent battery backup.Adapters themselves give around 5-6 hours playback at 70-80% volume.
Overall a worth purchase if you are looking for tws convenience with your IEM.
Bad
Absolutely loved the soundstage and neutral bright tuning of this iem.
Excellent 👌👌👌
Best in class adapter for various IEM's. I used it with KZ caster, Fiio JD1 and KZ ZEX. All works perfectly. My choice currently is with KZ ZEX. Instead of Touch, button system to control is too good and easily fits in our ear. ANC is not too aggressive, but quite good. Transparency mode is effective. So finally it's a perfect buy for our IEM's. KZ Rockzzz.
Anc & Transparency mode nice, Battery hrs fullfill & Mic quality top notch,
Soft touch Key function.
Nice product
Had received in a day itself and it’s all that I had expected and more.
The KZ ZS12 Pro X is a solid choice for those new to in-ear monitors or looking for an affordable upgrade from standard earbuds. Known for its emphasis on value and performance, KZ delivers a compelling package with this model.
### **Sound Quality**
The ZS12 Pro X has a V-shaped sound signature, meaning the bass and treble are slightly elevated compared to the midrange. This makes it ideal for genres like EDM, pop, and hip-hop, where punchy bass and sparkling highs are key. The bass is deep and impactful without overwhelming, while the treble is bright, though it might feel sharp to those sensitive to higher frequencies. The mids are slightly recessed but still clear, making vocals and instruments sound present but not overly emphasized.
### **Build and Comfort**
These IEMs feel sturdy, thanks to a mix of metal and high-quality resin. The ergonomic design fits snugly in the ears, providing good isolation from outside noise, making them great for commuting or casual listening. However, the included eartips might need upgrading for the best fit and comfort.
### **Cables and Connectivity**
The ZS12 Pro X features a detachable 2-pin cable, which adds versatility and longevity. If the cable wears out, you can easily replace or upgrade it. The braided cable also feels durable, though it can be slightly prone to tangling.
### **Who Is It For?**
This model is perfect for beginners who want to explore better audio quality without breaking the bank. It’s also a great option for gamers or casual listeners seeking a balanced mix of affordability and performance.
### **Final Thoughts**
For its price, the KZ ZS12 Pro X offers impressive sound and build quality. While it might not satisfy audiophiles looking for neutral tuning, it’s an excellent introduction to the world of IEMs for anyone seeking better audio clarity and detail.
**Rating: 4/5**
Great for beginners and casual listeners. Some fine-tuning or upgrades (e.g., eartips) might be needed for the best experience.
Clear vocals and deep bass, very impressed!
⭐⭐⭐☆☆
The sound quality is genuinely good, especially for gaming and music, with clear details and nice imaging. Unfortunately, after a few hours of use, the left side becomes noticeably quieter than the right. I've tried different devices, cables, and foam tips, but the issue still occurs. It's frustrating because the IEMs sound great when they're working properly, but the inconsistency makes them hard to recommend without reservations.
Great hearing experience but case too big for carrying in pocket so cant carry everywhere and price itself more than the iems
Perfectly fit , awesome sound quality
Striaght forward/Fantastic use/Good charging capacity
Good
This is by far the best IEM I would recommend for people who love to listen to music from films or live orchestral performances, the saturation is very good, and the sound is very natural, the bass is heavy and clean, I am rating this a 4 start only because it sometime feels that its not loud enough.
The iem shines with an immersive music experience, best kz experience i listened to so far. Good job TAS!
This is my first set of IEMs and unfortunately the treble is too harsh. If you listen to music at a relatively high volume then this isn't for you. I had to change the tuning to 123 up and 4 down and on top of that change the equalizer on the phone to get any acceptable sound and even that isn't something great like I was expecting from an IEM. My WF-1000XM3 and WH-1000XM4 are probably better. Maybe even the OnePlus Buds 4.
Please avoid this unless you know what you're doing. I should've listened to the reviews which states to go with the KZ ZS10 Pro X instead. Or Waner. But I was looking at this for the looks and metal build.
On the plus side, if you play competitive FPS games this has pretty decent sound separation. Maybe slightly better than the XM4 I use.
Great sounding IEMs
As usual.not to much expect.it convert iem into wireless
Better than most TWS in the market
Previously I had KZ IEM which experience was superb, tried to buy upgraded IEM but this seems mistake not even single time this KZ ZS12 pro X match my expectations.. seems wrong decision to choose it. 😔

If you loved Sennheiser ie 400 pro you'll probably love this too. Retains its dynamics and soundstage even with apple dongle (USA not EU) so it's easy to drive .
Great little DAC! Clean, detailed sound with better clarity, tighter bass, and good instrument separation. Compact, easy to use, and a solid upgrade for any IEM.
My first pair of IEM and I absolutely loved it🥰
I’ll recommend the audio store and purchase more in future
The product has a sturdy build and the ring light adds a clean, aesthetic touch that enhances its overall look. Using it with my KZ Castor Harmon Edition feels like listening to my favorite song for the very first time, with sound quality that is clear and immersive. It works smoothly with both Samsung devices and Windows, and the customization options on Windows make it highly versatile. The quick delivery in just one day was the icing on the cake, making this a well-rounded purchase that combines design, performance, and convenience.
Pairing this Harman Target Version with a Samsung A17 playing Apple Music and FLAC files and Fiio X1 DAP as a secondary source with FLAC files. When tuned to give preference to Mids as i prefer to hear the voices more than anything else, this comes out as a sweet sounding combination and tracks like Racy Chapmans Fast Car and Massive Attacks Teardrop shine beautifully. The Castor Pros are best listened at about 40% volume and and infact they do actually sound amazing at a high volume for bass heavy tracks such as EDM but for Trance and Rock the cymbals and snare drums sound better at 40%. This pair of iems and the combo sounds like money well spent so far and next i want to try analytical IEMs like the 7Hz. Thanks to the Audio Store for the rushed delivery.
Great purchase... excellent product
Good Product as expected
Worth every penny! This is not for bassheads as it lacks just a bit on the bass department, but the separation is awesome and the sound stage is also huge. Awesome for gaming as well! (Apex Legends, Arc Raiders, PUBG)
This is the replacement for my purchase of moon drop dsp chu2 which I bought in aug 2025 i don't know how it got damaged from last it stopped working on left side buds and after a few days mic also stopped working and i forgot to claim the warranty for it . So find this spare cable very helpful since I love these IEMS for real Tq AUDIO STORETEAM FOR THE smooth delivery
Great job on packing of the product. As a gamer I can say that, for fps games like PUBG , CS2 etc., Castor Pro is the best in under ₹2000
I recently bought this and am incredibly impressed with it. The build quality feels solid and premium right out of the box.
When it comes to performance, the amplification is fantastic—it delivers a clear, noticeable boost to the audio power and volume without sacrificing clarity. It is also incredibly easy to use; completely plug-and-play with zero hassle.
An awesome bonus is the inclusion of the Type-A to Type-C dongle/adapter. It makes it incredibly versatile to connect to different devices right away without needing to buy extra accessories.
Overall, it's a great purchase and definitely worth the money. If you are on the fence, just get it!
As an all rounder it fits my taste quite well,the only problem it really has is the male vocals being a bit recessed (not terribly recessed if you use vocal eartips),they are a tad bit overpriced seemingly,divine planar might be better,but for people looking for a fun entry into iem's,it's worth the price (some people say it's included DAC isn't enough,it works well enough as a temporary solution,yet to test if a dac makes a big difference or not).
Unsure if this is how most iem's are but the cable felt a tad bit short.
I had never used an IEM before, so this was my very first experience and I was genuinely impressed. As someone who loves music, I can confidently say this is one of the best investments you can make for audio quality. The sound is exceptional and absolutely worth the price.
To get the best possible audio experience, I would also recommend pairing it with a good-quality DAC, as it significantly enhances the overall output. ....
This is the most balanced sounding IEM I've used in this price. I am using the Type C variant, and I haven't experienced any issue regarding the playback whatsoever. It is equipped with the DAC chip CX31993, which is found on the dedicated DACs around the price of 1K. The cable is also a 4-core silver plated copper one, with really nice build quality. These are also really responsive to EQ Settings, tweaking the audio balance using a 10 or 31 band EQ makes the experience even more versatile.
The only cons I have noticed are regarding the in-box ear tips, I didn't find them to be very comfortable, so I had switch them with some other ear tips. Although, the metal built of the IEMs give them a really premium feeling, the glossy surface is extremely prone to scratches and they still get scratched even after using cautiously.
It is best in budget dac.
