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

CrinEar Reference (2026) against Campfire Audio Axion (2025). 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.

What reviewers said

Campfire Audio Axion

The Campfire Audio Axion is a wired USB-C in-ear monitor that pairs a single dynamic driver with a built-in DAC, delivering a balanced and immersive sound with punchy bass and a natural midrange. Its lightweight, comfortable shells and practical design make it a solid everyday option, though it lacks advanced features like ANC, app support, and custom EQ. Overall, it offers a convenient, modern listening experience with good imaging and build quality, but its resolution and treble extension have some limitations.

  • Pro:Punchy, well-defined bass
  • Pro:Natural and articulate midrange
  • Pro:Lightweight, comfortable shells
  • Con:Lower mids can sound congested
  • Con:Treble lacks crispness and extension
  • Con:Bass presence is limited

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
