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.

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.

This is a good🎉 product reliable and very good connectivity with the supported Type-c port and DAC is work perfectly all the time ✨❤️

Their small size is a blessing for me. It's the most comfortable audio device I've ever used and I can't wrap my head around how how good of a fit they are. The sound is also awesome.

Nice iem and sound quality is top notch
