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 Letshuoer S12 Ultra 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
Letshuoer S12 Ultra
The Letshuoer S12 Ultra is a wired in-ear monitor built around a single 14.8mm planar magnetic driver housed in a lightweight aluminum shell.

- Pro:Lightweight and sturdy aluminum-alloy build
- Pro:Easy to drive thanks to low impedance
- Con:No noise cancellation or isolation features
- Con:Planar timbre may not suit all listeners
