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 7 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. For 7 years between them, that is a thin return - treat this as a restyle rather than a new platform.

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

Yamaha EPH-M100

The Yamaha EPH-M100 are lightweight, wired in-ear monitors built around a single large-caliber dynamic driver for a warm, detailed sound. They include a single-button remote and microphone for calls or media control, and their 28-ohm impedance makes them easy to drive with most smartphones or laptops. With no active noise cancellation, they rely on passive isolation from their fit, making them a straightforward, budget-friendly choice for everyday listening.

  • Pro:Balanced, natural sound signature typical of Yamaha tuning
  • Pro:Very lightweight design (19g) for comfortable long sessions
  • Pro:Easy to power from phones or laptops due to 28-ohm impedance
  • Con:No active noise cancellation or wireless connectivity
  • Con:Single-button remote may lack volume controls or track skipping
  • Con:Passive isolation depends heavily on eartip fit
