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

Design and Build.
•
•
These speakers are heavy, and massive weighing about 8.1 Kg per pair. They are also built like a tank. The dense casing on these speakers allows little to no distortion or vibration on the wooden MDF. It's completely rattle proof, the dust protection covers on these are a huge plus, although they need a bit of force to remove them from the attachments.

Connectivity and App Support
•
•
I am currently using it on my laptop via a DAC and the included RCA to 3.5mm cable, due to this I am able to use exclusive mode on Tidal completely skipping the Windows Sound Card which enables a distortion free music experience. It also has HDMI e-Arc, Coaxial, and Optical Inputs. It also supports Bluetooth 6.0 with multipoint connect and LDAC on both of the devices connected. A solid plus. They do feature a small handy remote with all the necessary inputs on it and different presets(EQ), a mute switch, play/pause, and next/previous buttons and volume controls. The speakers connect via Edifier ConneX app which can be used to fix the Active Speaker Positioning, Update Firmware, Use a Custom EQ, (Saves to Speakers) and other things that you can do via the remote. It also features a power saving mode that you can choose after "X" minutes of inactivity.

Near Field Sound and Acoustics.

Because my desk only allows about 11 cm of clearance from the back wall, I was worried the rear bass ports would turn my room into a boomy mess. In practice, the 3-way architecture completely saves the soundstage. Sitting 2.5 to 3 feet away, having that dedicated 4.5-inch midrange driver prevents vocals and snare hits from getting buried under the low end. Getting the imaging right required deliberate positioning: I had to elevate my seating so my ears sit level with the midrange cones rather than the tweeters, combined with an aggressive toe-in toward my listening position. Once locked in, instrument separation is pinpoint sharp, and the 7-inch woofers deliver enough tactile punch that adding a separate subwoofer under the desk is completely unnecessary. There are also bass and treble knobs on the back to adjust it to your liking. Maximum output of 24 bit / 96Khz is supported.

Overall Experience from TheAudioStore
•

I would personally like to thank Mr. Pritam who answered all my doubts and shipped the product with extreme care and thorough packaging, the package was secured with more than necessary bubble wrap packing and I received my product on the 2nd Business Day even in peak festival time. I would definitely recommend TheAudioStore. Overall a superb experience with the product and everything!

I recently purchased the KEFINE Klean SV from The Audio Store, and my first experience has been excellent!

The package arrived securely packed with double wrapping and proper protection, and all the items were included. The silver tuning nozzle was already attached, so I could start listening straight away.

Coming to the sound, I'm genuinely impressed! I started listening to tracks like Buss Down and songs by Karan Aujla, and I really enjoyed the balance. The vocals are clear, the bass has a satisfying punch, and both come through without overpowering each other. The overall sound is exactly what I was hoping for.

I'm happy with my purchase so far and look forward to exploring more music with these IEMs. A great first impression!

it was a great experience listening to all the speaker options and choosing the right speakers at the audio store.
