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 6 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 6 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

TRN VX

The TRN VX is a wired, seven-driver hybrid IEM combining a 10 mm dynamic driver with six balanced armatures per side, offering strong technical performance and detail retrieval for its budget-friendly price. It delivers a generally full and balanced sound with controlled bass, though its tuning can be polarizing, with some finding the upper mids and treble potentially harsh or fatiguing. Build quality and comfort are praised, but the stock cable and included accessories are often seen as underwhelming.

  • Pro:Strong technical performance and detail for the price
  • Pro:Solid build quality and comfortable fit
  • Pro:Controlled bass response
  • Con:Upper-mid and treble can sound harsh or glassy to some ears
  • Con:Stock cable quality is below average
  • Con:Accessories are sparse
