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.

TRUTHEAR HEXA
The TRUTHEAR HEXA is a budget-friendly hybrid in-ear monitor that delivers a balanced, neutral sound with a hint of warmth, thanks to its single dynamic driver paired with three balanced armatures. It offers strong value with a comfortable fit, solid build, and excellent passive isolation, though its bass response is somewhat restrained and the soundstage feels intimate. This wired model is well-suited for critical listening and everyday use, but not ideal for gaming or active sports.

- Pro:Comfortable and lightweight design
- Pro:Solid build quality
- Con:Bass is a bit restrained
