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 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.

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
SEEAUDIO BRAVERY
The SeeAudio Bravery is a four-balanced-armature wired IEM that delivers a broadly appealing, U-shaped sound signature at a competitive $279 price point. It impresses with its bass response and smooth bass-to-mid transition, which is particularly notable for an all-BA design, while offering good soundstage separation and overall tuning. However, some listeners may find the sub-bass lacking in weight and the presentation less dynamic than expected, though it remains a solid, well-rounded choice in its class.
- Pro:Well-tuned U-shaped sound signature
- Pro:Impressive bass response for an all-BA design
- Pro:Smooth transition from bass into mids
- Con:Sub-bass can feel too subtle for some
- Con:Presentation lacks dynamic excitement
- Con:Low-end weight may be limited for bassheads
