AUDIOCULAR DAC Recommend asome sound quality it's pushing
Best product
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!!
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..👍🏻
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
I initially thought this case would be small and feel cheap, but I was surprised after receiving it. The size is actually bigger than expected, which turned out to be a good thing because it easily fits my IEMs along with a DAC and accessories without feeling cramped.
The case is quite rigid and sturdy, giving good protection while carrying it around. The build quality feels much better than what I expected for the price. Overall, really happy with the purchase and it works great for storing both IEMs and DAC together safely.
Hi Team, great product , impeccable service, at reasonable cost. Thanks Audio Store.
Most bast DACK on this prise range an existing case and type -c to USB converter otg buty full luck and wark quality thank you 🌹
Good dac, i had previously one 3.5 to c tye converter it was basic with no chip .this dac really draw out the juice from your phones to shake drivers . Nd if u guys have impedance issue you can use equilizer nd see the magic . This dac works well. Nd yes dac is essential to draw out the required Current/power.

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.
