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

Cozoy D2 (2026) against PULA UNICROM (2025). These are 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

PULA UNICROM

The PULA Unicrom is a lightweight, wired single-dynamic-driver IEM that delivers a bass-forward yet balanced listen, with a sturdy build and a comfortable fit that suits its budget-friendly price point. Its engaging low-end and strong midrange make it an appealing choice for those who prioritize musicality over pinpoint technical accuracy, though its sub-bass tuning may not suit every taste.

  • Pro:Engaging bass-forward tuning with strong mids
  • Pro:Solid build quality and comfortable fit
  • Pro:Detachable 2-pin cable adds versatility
  • Con:Sub-bass presentation may be polarizing
  • Con:Overall tuning not perfectly neutral
  • Con:Sound leans toward character over raw technical detail
