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 3 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 3 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said
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.

- 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

- Pro:Spacious and immersive soundstage
- Pro:Good dynamics and imaging
- Con:Slightly metallic upper treble
- Con:Average detail retrieval and resolution
