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

TFZ Aquarius

The TFZ Aquarius is a wired, single-dynamic-driver in-ear monitor built for detailed listening. It pairs an 11.4mm driver with a 50-ohm impedance and a wide 20Hz-40kHz frequency range, and its detachable 0.78mm 2-pin cable adds flexibility for upgrades. With no active noise cancellation, it focuses purely on sound quality for budget-conscious audiophiles.

  • Pro:Wide frequency response for detailed highs and deep lows
  • Pro:Detachable 0.78mm 2-pin cable allows easy replacement or upgrade
  • Pro:Compact single-driver design keeps tuning coherent
  • Con:Requires a separate amplifier or high-output source due to 50-ohm impedance
  • Con:No active noise cancellation, so not ideal for noisy environments
  • Con:Single dynamic driver may lack the separation of multi-driver setups
