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
Letshuoer x Gizaudio Galileo
The Galileo is a hybrid in-ear monitor that prioritizes a natural, balanced midrange over flashy tuning, offering a refined and easygoing listen for its price point. While its technical abilities are solid, they don't push boundaries, making it a dependable choice for those who value tonal accuracy over showy detail.
- Pro:Well-balanced, natural midrange tuning
- Pro:Refined and smooth overall sound
- Pro:Good value for its price range
- Con:Not groundbreaking in technical performance
- Con:Lacks extra features like noise cancellation
- Con:May not appeal to those seeking a more energetic or V-shaped sound
