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
TinHifi Dudu
The TinHifi Dudu is a budget-friendly planar IEM that delivers impressive technical performance, including a wide soundstage, strong detail retrieval, and clear, airy treble. Its tuning leans neutral-warm with textured bass and a forward upper midrange that some may find intense, but it remains a comfortable and easy-to-drive option for listeners seeking a realistic and analytical sound at a low price.
- Pro:Excellent detail and clarity
- Pro:Wide and immersive soundstage
- Pro:Comfortable and lightweight build
- Con:Upper mids can become tiring over long sessions
- Con:Midrange presentation may not suit all listeners
- Con:Tuning coherence is debatable
