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

DUNU Titan S2

The DUNU Titan S2 is a wired in-ear monitor that pairs dual dynamic drivers with a stiff yet flexible composite diaphragm for clean, detailed sound. It comes with swappable 3.5mm and 4.4mm plugs through a modular connection system, making it versatile for various sources. With low impedance and high sensitivity, it's easy to drive from most devices.

  • Pro:Dual dynamic drivers deliver rich, dynamic audio
  • Pro:Interchangeable 3.5mm and 4.4mm plugs for flexibility
  • Pro:Lightweight design (17.2g) for comfortable wear
  • Con:No noise cancellation, so isolation is passive only
  • Con:Cable is non-detachable, limiting upgrades
  • Con:4.4mm balanced output requires compatible source
