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

Both shipped in 2026. These are 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.

  • Pro:Natural mids and highs despite bass focus
  • Pro:Innovative brass shell construction
  • Con:Bass-heavy tuning not for everyone
  • Con:Very limited production run
  • Con:Only available used due to 2026 release
