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

EPZ X TIPSY STAR ONE

This wired collaboration between EPZ and Tipsy pairs a custom 10 mm dual-cavity dynamic driver with a blend of LCP and PU materials, aiming for clear and energetic sound. It's built for live streaming, stage monitoring, and attentive music listening, with a detachable 2-pin cable for easy swapping. The single-driver design keeps things simple, while the 64-ohm impedance suggests it pairs well with dedicated sources.

  • Pro:Detailed and engaging sound from a custom dual-cavity dynamic driver
  • Pro:Detachable 0.78 mm 2-pin cable allows for easy upgrades or replacements
  • Pro:Suitable for monitoring and critical listening due to its tuned response
  • Con:No active noise cancellation, so isolation relies solely on ear tips
  • Con:Higher impedance (64 ohms) may require a more powerful source for optimal volume
  • Con:Single dynamic driver can't match multi-driver setups in terms of raw detail and separation
