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. It delivers the signature planar sound of the S12 line—fast, detailed, and punchy—in a refreshed design aimed at hi-fi enthusiasts. With a low 16-ohm impedance, it pairs easily with most sources, though it lacks any active noise cancellation.
- Pro:Fast, detailed planar sound with strong dynamics
- 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
- Con:Cable and accessories are basic for the price
RAPTGO HOOK X
The RAPTGO HOOK X is a hybrid in-ear monitor that pairs a 14.2mm planar magnetic driver with a piezoelectric tweeter, delivering a lively and open sound with a strong bass-midrange balance. It stands out for its technical innovation and engaging presentation, though it can exhibit treble peaks that may fatigue some listeners and benefits from EQ or a good amplifier to reach its full potential.
- Pro:Open, natural soundstage with good dynamics
- Pro:Punchy, well-defined bass that complements the mids
- Pro:Unique planar-plus-piezo driver design for distinctive clarity
- Con:Treble can become sizzly or fatiguing at high volumes
- Con:Detail retrieval and layering not always top-tier
- Con:Best performance requires external amplification
