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.

What reviewers said

Campfire Audio Holocene

The Campfire Audio Holocene is a triple balanced-armature in-ear monitor with a reference-style, technically focused tuning that prioritizes clarity and detail retrieval. It offers a polished high end and solid build quality, though its low impedance and high sensitivity mean it can be picky about source pairing and may sound dry or sterile with certain gear. Its bass response is somewhat limited in versatility, with some listeners finding it either light or occasionally bloated depending on the setup.

  • Pro:Excellent detail retrieval and resolution
  • Pro:Reference-style tuning with strong transparency and layering
  • Pro:High-quality build and polished design
  • Con:Bass can be light or occasionally bloated depending on source
  • Con:Sensitive to source matching due to low impedance and high sensitivity
  • Con:Can sound dry or sterile with certain tips or recordings

CrinEar Reference

The CrinEar Reference is a wired in-ear monitor with a hybrid 2DD + 3BA driver setup, offering a balanced and detailed sound signature. It features a detachable 4.4mm balanced cable and relies on a tight seal for passive isolation, making it a strong choice for critical listening at its price point.

  • Pro:Hybrid driver configuration delivers rich, layered sound
  • Pro:Detachable 4.4mm balanced cable for flexible connectivity
  • Pro:Good passive isolation from proper eartip seal
  • Con:No active noise cancellation, so external noise isn't fully blocked
  • Con:Requires a balanced source to fully utilize the 4.4mm connector
  • Con:Fit may be finicky for some users to achieve optimal seal
