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 S

The DUNU Titan S is a wired in-ear monitor that uses a single 11mm dynamic driver with a special liquid crystal polymer diaphragm, delivering a broad frequency range from 5 Hz up to 40 kHz. Its lightweight zinc alloy shell keeps each earpiece at just 17 grams, and the detachable cable adds convenience for users who like to swap or replace wires. This model is aimed at budget-conscious listeners who want a neutral, detailed sound without extra features like noise cancellation.

  • Pro:Lightweight zinc alloy build
  • Pro:Detachable cable for easy replacement
  • Pro:Wide frequency response for detailed treble
  • Con:No noise cancellation for noisy environments
  • Con:Wired only, so no wireless option
  • Con:Single dynamic driver may lack bass impact for some
