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 2 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.

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
Sivga Nightingale
The Sivga Nightingale is a wired planar magnetic IEM that prioritizes an engaging, musical tuning over strict neutrality, with a notable emphasis on midrange clarity and an airy, spacious soundstage. It delivers strong technical performance in imaging and presentation, making it a specialized choice for listeners who value immersive, lively sound rather than a bass-heavy or universally balanced profile.
- Pro:Airy, immersive soundstage
- Pro:Strong imaging and technical detail
- Pro:Engaging mid-focused tonality
- Con:Not a neutral or all-rounder tuning
- Con:Limited bass impact for some listeners
- Con:Specialized appeal may not suit everyone
