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

Cozoy D2 (2026) against Hidizs MK10 ArcSonics (2025). These are 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

Hidizs MK10 ArcSonics

The Hidizs MK10 ArcSonics is a wired single-dynamic IEM that delivers sharp detail and quick transients, leaning toward a bright, revealing U-shaped tuning that suits treble and vocal-focused listening. Its 10mm driver, 4.4mm balanced connection, and detachable cable offer solid technical performance for the price, though passive isolation is weak and the sound may not satisfy bass lovers. The build is attractive but slightly heavy, and the included cable feels less durable than the shells.

Pro:Excellent detail retrieval and fast transient response
Pro:Clean, transparent, bright tuning with strong treble extension
Pro:Attractive design with detachable 4.4mm balanced cable

Con:Poor passive isolation
Con:Unusual imaging characteristics
Con:Upper-mid/treble energy can be fatiguing
