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 7 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 7 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 V90

The TRN V90 is a budget-friendly hybrid IEM that pairs a single dynamic driver with four balanced armatures for detailed, lively sound. It offers a comfortable metal build and strong bass, though its V-shaped tuning with an energetic treble may not suit listeners seeking perfect neutrality. Overall, it's a solid value pick for those wanting engaging sound without breaking the bank. Its wired design with physical controls keeps things straightforward, and the detachable cable adds convenience, though the stock cable is often cited as a weak point. With no ANC, it relies on passive isolation, making it best for quiet environments. The 10mm dynamic driver handles lows while the BAs cover mids and highs, resulting in good detail retrieval for the price. Soundstage is average, and the upper-mid emphasis can be fatiguing on longer sessions, but the overall package remains compelling for its cost. The 22-ohm impedance and 110dB sensitivity make it easy to drive from most sources, including phones and dongles. Build quality is a highlight, with a metal shell that feels more premium than its price suggests. While the tuning leans V-shaped with recessed vocals, the V90 still impresses with its punchy bass and crisp treble. For those who prefer a warmer, smoother signature, this may not be ideal, but it's a fun, dynamic listen for bass and detail lovers.

  • Pro:Detailed and lively hybrid sound
  • Pro:Comfortable metal build with detachable cable
  • Pro:Strong bass response for a budget IEM
  • Con:V-shaped tuning with recessed mids and vocals
  • Con:Upper-mid/treble can be fatiguing
  • Con:Stock cable quality is poor
