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 4 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 4 years between them, that is a thin return - treat this as a restyle rather than a new platform.

The detachable 4.4mm balanced cable adds versatility for audiophiles with compatible sources.

- Con:Requires a source with a 4.4mm balanced output for full benefit

FATFREQ MAESTRO MINI
The FATFREQ MAESTRO MINI is a wired hybrid IEM that leans heavily into bass-forward tuning, delivering a powerful low end that stays impressively controlled for its class. It's a niche pick best suited for bass enthusiasts, though its overall versatility and build quality may not justify its premium price for everyone.
- Pro:Powerful yet controlled bass response
- Pro:Hybrid driver setup adds clarity in mids and treble
- Pro:Decent all-genre usability for a bass-focused IEM
- Con:Build quality feels compromised for the price
- Con:Sound signature is niche, not for neutral listeners
- Con:Lacks universal appeal outside bass-heavy genres
