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 D1 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

1MORE E1001

The 1MORE E1001 is a wired hybrid in-ear monitor that pairs a 16mm dynamic driver with two balanced armatures to deliver a rich, detailed sound signature at a budget-friendly price. Its all-metal build, comfortable fit, and generous accessory package make it a compelling pick for listeners seeking premium features without the premium cost. While its tuning is generally balanced and engaging, it does have some minor limitations in soundstage width and cable handling.

  • Pro:Excellent value for a triple-driver hybrid design
  • Pro:Solid all-metal construction with a premium feel
  • Pro:Comfortable, secure fit for extended listening
  • Con:Cable is prone to noticeable microphonics
  • Con:Soundstage feels somewhat narrow and intimate
  • Con:Instrument separation is only average for the price

COZOY D1

The COZOY D1 is a wired ultra-budget IEM that stands out for its mature, balanced tuning and robust build, delivering sound quality that exceeds its modest price point. While it excels in comfort and value, its stock eartips can hinder the experience due to poor fit and sealing issues.

  • Pro:Excellent value for the price
  • Pro:Comfortable and well-built shell
  • Pro:Mature, balanced sound signature
  • Con:Stock eartips are too small and often fail to seal
  • Con:No active noise cancellation
  • Con:May require aftermarket tips for optimal sound
