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
Both shipped in 2025. These are 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
Ziigaat Horizon
The Ziigaat Horizon is a wired tribrid IEM that delivers impressive technical performance for its price, featuring a spacious, holographic soundstage and strong detail retrieval. Its W-shaped tuning balances clarity and engagement, though its energetic treble and lighter bass impact may not suit everyone. While the sound quality is a standout, the build and accessories feel less premium than the audio performance.
- Pro:Excellent technical ability and detail retrieval
- Pro:Large, holographic soundstage with strong imaging
- Pro:Well-executed W-shaped tuning that balances fun and precision
- Con:Treble can become fatiguing or slightly sibilant for sensitive listeners
- Con:Mid-bass punch is limited, with bass more technical than physical
- Con:Build quality feels somewhat cheap for the price
