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
TANGZU x HBB Wu Heyday Edition
This is an HBB-tuned revision of TANGZU's Wu series, featuring a single 14.5mm planar magnetic driver housed in an aluminum body. It's designed for audiophiles who prefer a neutral, balanced, and open soundstage from a planar IEM. The wired, detachable cable and 2-pin connector add convenience for swapping cables.
- Pro:Neutral and balanced tuning for accurate sound
- Pro:Spacious soundstage with good imaging
- Pro:Lightweight aluminum shell
- Con:No noise cancellation, so isolation is limited
- Con:Requires a good source due to low 16-ohm impedance
- Con:Planar driver may need burn-in for optimal performance
