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

TRN Medusa

The TRN Medusa is a budget-friendly single dynamic-driver IEM that delivers a warm, bass-forward sound with a slightly V-shaped signature, making it an engaging pick for those who prioritize punch and energy. Its detachable cable and solid accessory package add practical value, though its midrange body and handling of intricate tracks are less impressive. Overall, it's a fun, capable performer for the price, especially for bass lovers.

  • Pro:Punchy, elevated bass response
  • Pro:Warm, engaging tuning with energetic treble
  • Pro:Detachable 0.78 mm 2-pin cable for easy upgrades
  • Con:Midrange lacks some body and richness
  • Con:Struggles with highly complex or dense music
  • Con:No active noise cancellation (wired-only design)
