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

1MORE H1015

The 1MORE H1015 is a wired hybrid in-ear model that pairs a single dynamic driver with two balanced armatures for a detailed, balanced sound signature. Its aluminum build and braided cable give it a premium feel at a moderate price, while the 32-ohm impedance makes it easy to drive from most devices. The soundstage is somewhat limited by the in-ear form factor, but overall it offers strong fidelity and comfortable long-listening sessions.

  • Pro:Balanced, detailed sound for the price
  • Pro:Sturdy aluminum-alloy construction
  • Pro:Kevlar-reinforced cable for durability
  • Con:Soundstage is constrained by in-ear design
  • Con:No inline controls or microphone
  • Con:Wired only, with no wireless option

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
