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 x Hangout.Audio: Odyssey 2
This wired hybrid IEM pairs a 10mm bio-cellulose dynamic driver with three balanced-armature units to deliver a versatile, reference-leaning sound signature. It focuses on deep, controlled bass and articulate mids and treble, making it a solid choice for audiophiles who want detailed, balanced performance without noise-canceling features.
- Pro:Rich, impactful low-end from the bio-cellulose driver
- Pro:Clear and detailed midrange for vocals and instruments
- Pro:Airy, well-extended treble without harshness
- Con:No active noise cancellation, so isolation relies on fit
- Con:Requires a good source or amp to fully shine
- Con:Hybrid design may need some burn-in time
