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
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
Moondrop KATO
The Moondrop KATO is a single 10mm dynamic driver IEM with a DLC diaphragm, offering a balanced and smooth tonal presentation that appeals to listeners seeking refinement over aggressive tuning. It is easy to drive thanks to its 32-ohm impedance and high sensitivity, and it comes with a generous accessory set that adds to its value. While it impresses with its cohesive sound and wide soundstage, it may lack impact in the low end and can occasionally sound sharp or fatiguing to some ears.
- Pro:Balanced and smooth tuning
- Pro:Easy to drive with any source
- Pro:Wide soundstage
- Con:Lacks low-end slam and impact
- Con:Can sound sharp or fatiguing at times
- Con:Not the most technically resolving option
