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 8 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. For 8 years between them, that is a thin return - treat this as a restyle rather than a new platform.

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

FiiO F5

The FiiO F5 is a semi-open in-ear monitor built around a single 13.6mm dynamic driver, delivering a smooth and balanced sound with a notably wide soundstage. Its detachable MMCX cables, including a balanced option in the box, add versatility for wired listeners, though it doesn't chase the ultimate detail retrieval of pricier models. This is a solid, affordable choice for those prioritizing an airy, natural presentation over analytical precision.

  • Pro:Wide, open soundstage for a dynamic driver
  • Pro:Detachable MMCX cables with a balanced cable included
  • Pro:Smooth, non-fatiguing tonal balance
  • Con:Lacks ultimate detail and clarity compared to higher-end IEMs
  • Con:No active noise cancellation or app support
  • Con:Semi-open design may leak sound and let in ambient noise
