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 Letshuoer D02 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.

Letshuoer D02

The Letshuoer D02 is a budget-friendly wired IEM with an 11mm dynamic driver, delivering a lively, balanced sound with notable treble detail and a comfortable, practical design.

It suits listeners seeking clarity and vocal presence in a compact daily driver, but may disappoint those wanting heavy low-end punch.

  • Pro:Airy and detailed treble with good sibilance control
  • Pro:Comfortable, compact build with stylish design

  • Con:Bass is lean and lacks deep sub-bass weight
