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 CrinEar Reference is 5 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 5 years between them, that is a thin return - treat this as a restyle rather than a new platform.

  • Con:No active noise cancellation
  • Con:V-shaped tuning may not suit neutral purists
