Customers praised this 8-core silver-plated cable as "best budget cable" with exceptional build quality and sturdy construction. The metal jack, built-in microphone, and inline controls received high marks. Reviewers noted it's heavier than stock cables and works well for gym use. Some concerns: paint chipping on connectors, buttons incompatible with certain devices, and one shopper felt audio got quieter over time.
its been 10 days and so far the dac is working fine and i hope it ll work for the long term. The package arrived in great condition and on time, the quality seems great given that it is audiocular.
Cable ki built aur quality price k hisab se badhiya h lekin Audiocular yaar apne connector / jack ko metal colour se paint krne ki jagha tum ise metal ka bhi to bna dete aur kuch nahi to metal ki covering hi de dete ispe se colour chips ki trha utar rha h🥲
Or baki cable ki built or strength me koi kami nahi h👍🏻
It Perfectly fit my bunny's. Fixes to ear way better and Definitely heavier than the default dsp cable.
Audiocular packaging is premium always give a small pouch which can be very handy.Initially Right side was not working in my KZ Harman target Balanced version. Date Recd 7th Oct 2025! every thing is awesome Love Pritam for being Down to earth.I am going crazy at age 51 with this music world man
I got these cables for my CHU II because I broke the stock cable.
For the following reasons I would say it's a solid recommendation for it's price.
The cables themselves are not as heavy as they might look and more importantly, they are not "stiff, ear hooks are also fairly comfortable.
Also, they don't particularly retain shapes and seem to be freer and tangle free.
The quality on the cables is good, it's been almost two weeks, and I haven't seen any quality issues come out.
The mic quality on calls is decent, very serviceable.
Don't expect upgrade cables to change the tonality of your IEMs.
These don't have a chin-slider, I would have loved to see that.
(THE COOLEST PART, they include a free hard case and tbf it's actually a good case better than some listed even for around 300INR out there)
The Audiocular C03 is an exceptional value for money upgrade cable in the market with a decent mike and in line controls along with amazing build quality thank you The Audio Store for fast Delivery
I had kz castor but wanted something different I have chosen few iem headphones in cart
Thank you to pritam sir of Audiostore pune for suggesting the cable with mic and for audiocular iem earphones awesome sound
Once again thank you Pritam sir for suggestion and also would thank Me joshi sir for his helpful nature
He is very helpful
Thank you Audio Store Team for your great support. Hardly it took 48 hours to deliver from Pune to Kolkata, not even 72 hours!
The cable is solid and magnificently elevated the overall experience. The amplification through 8 strands along with the clarity is so audible that anyone can simply understand what they bought. I basically needed the remote but got much more than that. Anyone serious about every note can easily go for this or above as per your need and choice.
Using it with truthear crinicle zero red and works perfectly. Loving it
It makes my IEM sound bright and more detailed. 3.5mm cables in general are more versatile for daily use.
The mic is good and the control buttons on it is also very useful. But the cable itself is very heavy that it's hard to use for longer period of time
Superb Cable!
Works well with Zero 2
Value for money product
Best budget dac
I am using these with Zero 2. The Zero 2 cable lasted me for 2.5 years and I had to get a new cable. And this new version is absolutely amazing. I use my IEMs for gym sessions and this 8-core cable is so sturdy for that use case. My previous cable didn't have mic as well, so this one was a proper upgrade over it. And over all as well, this is very very good, the jack quality, the build quality, the sturdiness is all amazing.
Feels solid and has good build quality,hope this one holds up well.
yup as i said in the title it's the best budget cable you can ever get under 1k, i own a qkz t1 cable and it was so soft compared to the C03 it just feels so durable in the hand the 3.5mm jack is made of metal too and it's heavy, in the end it's a great purchase.
my unit had no issues, delivery by theaudiostore was smooth arrived within 2 days of ordering and the overall quality is great for the price with a decent microphone.
Good quality cable. Works well for taking calls.
Best

Excellent , go for it , everything is good

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 good but could be a bit sharp sometimes may be balanced by EQ. But one problem in my type C unit, after 3 days it stop sound out of nowhere, while listening music, or watching movie/yt. Have to plug out plug in to get the audio back.
This is a magical DAC, I don’t believe ki isne mere headphones main jaan daal di ho
Really the quality of aurora ultra is out of the box , literally if you never use an iem and experience first time you feel actual music. Aurora ultra give life best experience.
This is only possible because of the audio that my first experience and the audio store surve there best to just create my best experience thanks a lot for protective, timely delivery and
Again thanks for giving that service and seamless experience to the team
