Generation & platform
The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?
Same generation
The Cozoy D2 is 2 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price.

What reviewers said
Cozoy D2
The Cozoy D2 is a budget-friendly wired IEM that pairs a 6 mm beryllium driver with a 10 mm graphene-composite driver for a dual-dynamic setup. It offers a flexible connection via a 2-pin 0.78 mm cable that includes swappable 3.5 mm and 4.4 mm plugs, catering to both standard and balanced sources. With a 20-ohm impedance, it's easy to drive from most devices.
- Pro:Dual-driver hybrid design for detailed sound
- Pro:Interchangeable 3.5 mm and 4.4 mm plugs
- Pro:Low impedance (20 ohms) for easy pairing
- Con:No active noise cancellation
- Con:Wired only, limiting portability
- Con:Budget build may not suit all users

- Pro:Detachable 2-pin cable
- Con:Treble peak may be noticeable on some tracks
- Con:Average technical detail
- Con:Soundstage depth is limited
