Good neutral set. Airy and open staging but with forward vocals although lacking in extension. Great layering and details but not 3D and more flat. Vocals could also be more open, and feels "stuck".

Neutral and laid back tuning. Great layering and separation and resolution. Great treble extension and air without being too sharp and light like other planar iems. Bass is also not light and floaty, and doesn't feel like planar bass - not slamming, but tight and well-textured. Vocals are laid back, but not too pushed back although it's not the most extended and powerful, but works very-well as a neutral set. Nice and open staging, and is the direct upgrade to the Hexa and Sonus. Very good safe all-rounder.
Youtube Video Summary

Letshuoer S15 takes the planar recipe in a more natural, neutral direction, dialing back the upper-mids/treble glare that made earlier S12 variants feel “planar.” The result is a heavier note weight, smoother edges, and a timbre closer to a good dynamic driver—without the etched, floaty thinness common to many planars. Vocals sit forward with less Harman-style shout, bass carries satisfying sub-bass rumble with tight mid-bass separation thanks to planar speed, and overall fatigue is low. The trade-off is a presentation that’s more relaxed than hyped: treble sparkle and micro-detail aren’t spotlighted, and those craving sizzle may find it a touch polite.

Against its siblings, S15 is the cleanest, most neutral option—more open and balanced than the darker, ultra-chill S08, and more refined/grounded than older S12 iterations that pushed treble energy. The newer S12 2024 brings back liveliness and air while staying smoother than previous S12s, but S15 remains the pick for a reference-leaning planar with convincing timbre. It costs a bit more than S12 2024, yet what you’re paying for is timbre quality, note density, and a fatigue-free listen that still carries enough low-end punch. For listeners prioritizing naturalness over fireworks, S15 feels like the most mature expression of Letshuoer’s planar line.

Warmer tuned planar with less emphasis on the lower treble; easier to listen to for longer periods Still plagued by planar timbre, overall clarity takes a hit from warmer signature, slight subbass rolloff to my ears

Smooth and balanced with really great detail retrieval. Slightly warm which makes vocals sound rich and instruments sound full. Jack-of-all-trades. If you can swing $370 for this and aren't willing to go up to $530+ for something marginally better, then just buy this and don't look back.

Great tonal balance with technicalities to back it up. Probably the best treble balance you find up to its price point. Mid-bass won't be for everyone.
