I have an HD650 with stock cable (3.5mm, 6.3mm) and a Tripowin Granvia (4.4 mm termination) and to pair with my source (iBasso Dx220 Amp 1 MK II) i needed this cable. I had researched a lot and most of those cables were either expensive or aesthetically not good (bulky). I had read about the ear audio cables which were made in India and heard very good reviews about them from various forums. TAS had them in stock, and it was a seamless experience buying from them. The delivery happened very quick too.
The cable - Looks and feels it lasts a lifetime, the terminations are made really well, no flex whatsoever when connected. I'm able to enjoy the HD 650 at its max potential due to this cable. Thank you Ear Audio, absolutely well made cable, and i love the name "Ear Audio" :-). I'd also like to get a 4.4 mm balanced to dual RCA (3 mtr) from you if that's available.
TAS ~ thank you for your quick and prompt delivery and very honest pricing. This may have been my first purchase from you, but this experience will make me lean towards more in the future.
Wishing you the very best Ear Audio. You guys compete with the best out there

The cable is pretty good, connection remain intact, also there is not any sound tuning change.
Thanks for the review! We're glad you like it.
Nice connector cable for 4.4 mm to 2.5mm. EarAudio is good brand. hopewe will get many more IEM cable option from EarAudio. We definitelyneedhome grown brand. Earlieralso done somedeal with Niranjan bhai from EarAudio
Though I was a bit concerned to buy a dangling type adapter, the doubts were removed when it arrived. Very well made. good quality check and looks good too. Earaudio is also an Indian brand, so that's a bonus supporting a brand in a niche low volume area. Bought the 4.4mm to 2.5mm as well.
Thank you for the positive review of the EarAudio 2.5mm male to 4.4mm female Adapter Cable.

Compared to the expensive balanced adapters this one is quite nice in quality and does the job perfectly.
Thank you for your feedback! We're glad to know that this adapter cable is affordable and performs well.
This works well. Quality is very good.
The Performance of this Balanced Adapter is Excellent.
Thank you for your review. We're glad to hear that you're satisfied with the performance of the adapter.
TL;DR: EarAudio adapter is great, if you need balanced, go for it, its worth a shot.
Wanted to use my sennheiser HD660S with the balanced port of fiio btr5. I do use senns with ifi hip dac as my main driver, so just wanted to try the fiio balanced option. So, needed a converter which could convert 4.5mm male end of senns cable to 2.5mm male end (fiio has 2.5mm female input end for balanced connection).
Senns do come with 3.5mm regular cable so I had already used the fiio btr5 with senns (on 3.5mm) and was quite impressed with the output, but was still curious about balanced connection, so got the earaudio converter to give balanced a try and it was worth it.
The connector / converter (EarAudio 2.5mm male to 4.4mm female Adapter Cable) is of great quality, I don't think there's any loss in quality at all, at least while using with stock senns cable (which are already quite good). Serves the purpose well, build is great as well.
So, for someone who'd want a couple words about balanced connection, it's a hobby guys. For me, balanced (on fiio) sounded way better than single ended because fiio btr5 provides more power output in its balanced output than its single ended connection and secondly, btr5 balanced output is just way better in every way than its 3.5mm counterpart.
I used the adapter with senns hd660s, fiio fh3 (4.4mm balanced cable). For iems, its not that exciting to go balanced route as iem (in general) don't need that much power but if you have a full size headphone lying around which could use balanced, its worth a shot to try balanced (with something like btr5).
Caution: ifi hip dac also has balanced, but its balanced is useless for iem as it hisses a lot with iem, so before going balanced, make sure to read some reviews.
As for my iem, FH3 (with btr5), I'm using them with a balanced 4.4m cable which just changed the way it sounded originally. Fh3 with 4.4mm connection is a different beast, punches above its weight and in this particular case, the balanced connection was super worth it.
Good quality and serves the purpose.
The unit itself is built well and works perfectly. I wanted a 4.4mm to 2.5mm connector for my BTR5 as most of my IEM cables and headphone cables are 4.4mm cables.

I am very satisfied with the purchase from The audio Store. I wanted a balanced sound IEM as I listen to all type of music. I am coming from a TWS community where I use Nothing ear 2024 ,earlier used oppo enco ear 2 pro and oppo enco M31.
Sound Signature :
I found the sound of this IEM is very clean with good instrument separation and good sound stage. If I talk about the base , deep base rumble is present but don't expect Good punch , Kick drum and guitar base sounds excellent. Both male and female voice feels heavenly to my ear. I am little treble sensitive so I found little uncomfortable when it comes to high frequency.
Pros :
1. Build Quality is superb
2. Very comfortable to wear for long listening.
3. It sounds excellent in my opinion
4. We get 3 different nozzle filter for different sound Signature. And it actually works but don't expect huge difference.
Cons :
1. It has little 'hishis' sound in the high frequency, not sure if it is coming because of the dac I am using (audiocular beam) .
Comparison :
If I compare with my Nothing Ear 2024, I will say it better than Nothing Ear in terms of sound quality and instrument seperation and I prefer bass in my Nothing Ear 2024 .
Final Conclusion : It stands with the expectation.
Absolutely amazing speakers, very good sound quality and build. Received in proper packaging the very next day after placing order. Very good service by TAS.
The DAC produces excellent sound quality (tight lows, clear mids and crystal clear highs) from both my android phone and windows laptop, using any IEMs or larger studio grade headphones. The online shopping experience from The Audio store was also great. Product was received within the scheduled delivery time in good packaging. Thanks.
The bass is so powerful, it feels like listening to a mini subwoofer! Really enjoyable sound and great value for the price.
Using it with Fir audio kr5 and now I'm not getting crackling sound i was getting with cayin ru7, very happy with this amp dac.
Good Product, relaxes muscles and relieves tension effectively. It is compact, easy to use, and highly recommended for quick pain relief.
The TANCHJIM Bunny Type-C DSP Plug with Mic IEM offers clear sound quality, good detail, and a comfortable fit. The USB-C connection is convenient, and the microphone is useful for calls and everyday gaming. The audio is enjoyable for music and helps with hearing footsteps and in-game details in Valorant. Overall, it’s a good choice for someone looking for a compact, wired IEM with a built-in microphone and a Type-C connection.
I have been using these for about 12 days, and that is 3.5mm with mic.
Look and feel:
In this price range this is the best looking iem with premium silver plated cable and unibody metal housing.
Build:
I don’t have any issue with build here cause as I have already told that earbuds itself has metal housing and also even 3.5mm jack is metal.
Cable looks fine to me, and i don’t Think that the cable will go anywhere for at-least 2 years.
The only thing is that the cable tangles a lot and it is evident by looking at the type of the cable.
SOUND:
I will not waste your time with the things you already know anymore…
Sound here is quite spacious with good soundstage. Since i myself is not a gamer i can’t tell about gaming but in music department sound is crystal clear and detailed with sharp highs and it lacks the thumpy base that some of you won’t like.
Now the thing is i have mixed opinion about these iems.
Sometimes i like it and sometimes I don’t…cause it lacks punchy base but has sparky treble that can irritate your ears if you pair them with a dac that is already focused on treble like audiocular spark.
But when i pair them in ipad 3.5mm jack these sounds better with great details and base.
After searching heavily on internet I found that this one should be better paired with AUDIOCULAR NOTE-S, since NOTE-S has hardware level EQ, i can tone down the sharp treble a bit and increase the low end slightly to get more base with the help of audiocular app.
So imo if you have these iem then pair them with audiocular NOTE-S and that is highly recommended from my side.
Thankyou.
It is one of the best budget dac if you want sparky and clean treble, though it does not have any kind of equaliser cause it is just normal plug and play type dac.
If your earphones lack in treble section then go for it.
But if your earphone have high treble already then believe me you will not like these.
I have cca pheonix that is already a treble heavy iem and after pairing them with spark it is producing even more treble, and that is very sharp.
So in my opinion go for audiocular NOTE or NOTE-S, cause Note-S has hardware level equaliser that decreases the treble frequency.
I have Soundcore Q20i headphones and spark works great with them cause it add those extra sparky treble that Q20i lacks, and base is also good.
Best iem and looks stunning.
Service is also good and fast.
Enjoying my first iem very much.
Perfectly distribute base and treble and the vocal smoothly spread to your ear . One of the best low budget deck for Music lovers.
Kefine klen sv is clean and awesome
Honestly this is my 1st iem
And This sound blow my mind 💀🔥
Kz duonic iem nice sound

I just received my Cozoy D2 and wanted to drop some quick impressions on the unboxing experience and included accessories before I sit down for proper listening sessions.
* Packaging: The IEMs arrive in a sleek, professional black presentation box with dense foam cutouts that keep the earpieces perfectly secure.
* Design & Build: The earpieces look stunning in person. The dark, marbled faceplates give them a premium, custom-like aesthetic with the Cozoy logo cleanly integrated into the design.
* Cable: It includes a high-quality, thickly braided black cable. It feels durable, features standard 2-pin connectors (clearly marked with 'L' and 'R'), and has a solid metal termination housing.
* Included Accessories: The package includes a neat grey Cozoy-branded carrying pouch for safe storage and an owner's manual. There is also a dedicated accessories box, which houses the eartips.
Overall, the unboxing experience feels very premium. The build quality of both the shells and the stock cable is top-notch right out of the box.
I'll be hooking these up to my CrinEar Protocol Micro DAC and testing them with offline FLACs on USB Audio Player PRO soon. I will upload a second review detailing the sound signature—specifically how their balanced tuning handles Indian classical, qawwali, and ghazals—once I've put them through their paces.
