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
PULA PA02
The PULA PA02 is a wired hybrid IEM that blends one dynamic driver with four balanced armatures to deliver a spacious, dynamic sound with a mostly natural and neutral-leaning character. It offers strong value in the sub-$200 range, with good imaging and engaging tuning, though its technical performance and timbre have some notable compromises. The set responds well to more powerful sources, which can help unlock its full potential.
- Pro:Engaging, mostly natural tuning
- Pro:Spacious and immersive soundstage
- Pro:Good imaging and dynamics
- Con:Slightly metallic upper treble
- Con:Average detail retrieval and resolution
- Con:Soundstage not exceptional among rivals
