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
JUZEAR HARRIER
The JUZEAR HARRIER is a well-built, smooth-sounding tribrid IEM that prioritizes balance and refinement over flashy excitement. Its strength lies in cohesive, natural vocals, clear treble, and comfortable long-listening sessions, making it a dependable all-rounder for those who value polish and detail. However, its polite bass and restrained tuning may not satisfy listeners craving more energy or impact.
- Pro:Excellent build quality and premium accessories
- Pro:Smooth, natural mids with clear vocal reproduction
- Pro:Comfortable fit suitable for extended listening
- Con:Bass is soft and lacks punch for bass enthusiasts
- Con:Tuning can feel too restrained or uninvolving
- Con:Treble is polite and not very forward
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
