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 KBEar KB02 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.

It's a solid choice for listeners seeking a lively, low-end-focused sound without spending much.

  • Pro:Hybrid driver design adds texture and depth
  • Pro:Easy to drive with phones or dongles
  • Con:No noise cancellation (wired only)
