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: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

With a wide frequency response and high sensitivity, it aims to deliver clear, energetic audio across genres.

  • Pro:Detachable 0.78mm two-pin cable for easy replacement or upgrades
  • Pro:Low 18-ohm impedance works well with phones and basic dongles
  • Pro:Single dynamic driver provides a cohesive, natural tone
