This is a magical DAC, I don’t believe ki isne mere headphones main jaan daal di ho
AUDIOCULAR DAC Recommend asome sound quality it's pushing
Good case to protect your iem
Such a great 👍 product
The product functioned flawlessly for 11 months and ranked as the top option in its category, yet it abruptly stopped working and is no longer detected anywhere.
Good One. But it doesn't have app support as this is the old model. it doesn't have audiocular app support. it is same as 699 rs DAC. Not have any huge difference,
Great great DAC for majority of the audience. Does a great job in audio quality plus if you use a dedicated app that directly interacts with DAC that is just incredible!!
KZ Duonic ka sound sach me bhut acha hai aur iski overall quality kamal ki hai. planar driver hone ki wajah se clarity next level milti hai. Bass tight hai aur instrument separation bhi bohot clear hai. Isme music suno bohot acha experience hota hai . Highly recommended if you love high-resolution audio!
It just works amazing with all of my audio products
Really good DAC and perfect for apple devices as it does not reduce the volume like few other DACs..and very good delivery experience from TAS..👍🏻
Excellent experience with TheAudioStore.in!
I ordered the KZ Duonic Tri-Magnet IEM, which was already going out of stock everywhere, and despite multiple courier issues from Blue Dart, the store support team stayed responsive and assisted throughout the process.
Packaging was good, product is genuine, and customer support was polite and helpful during the delay. The delivery issue was mainly from the courier side, not the store.
Finally received the IEM safely and absolutely loving the sound quality. Would definitely recommend TheAudioStore.in for audio enthusiasts and IEM lovers 🎧
It is my first iem that i have purchased and it turned out to be the best decision ! I researched a lot before buying it as i am a bass lover. Finally bought KZ Duonic with switches c type. Every note is so clean and for every type of song it adjusts the sound. Delivery was before time and even the packaging was great! Thank you The Audio Store ❤️
Its perfect no doubts there but the silver plated itself is high quality but wire built and the eartips are of low quality mic is clear and perfect.🔥👍
I loved it , surprised totally. What a sound separation.
I was a bit sceptical about ordering it from The Audio Store as I order from Headphone Zone.
But great shopping experience with The Audio Store.
Good product and excellent packing, pouch was also good quality one
Does nice job
Observed noticeable difference iin audio quality after using this dac, heard reviews complaining about static white noise but I haven't experienced any such issues yet

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

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.
