Letshuoer S15 VS Moondrop Blessing 3 Aqua

Youtube Video Summary

The Moondrop Blessing 3 Aqua is a Japan-only edition (~$400) built on the B3 platform with a 2DD + 4BA array. The shell mirrors the Blessing 3—comfortable, durable, translucent, and tastefully styled with the Aqua faceplate—while the accessory pack is standard fare. The weak link is the microphonic cable (the same type used on other Moondrop models), which begs for a swap to something quieter.

Sonically it’s slightly V-shaped and bright-leaning yet surprisingly natural: smooth, clean, and fun with a linear bass shelf that avoids bloat. Versus the regular Blessing 3, Aqua subtly fills the “bass tuck,” trims the upper-mids a hair, and adds a hint of upper-treble sparkle—engaging for treble-heads and mid fans, but not the pick for bass impact seekers. In graph terms it reads coherent and tasteful, though that added air can push into brightness on sensitive ears. Compared with Moondrop’s own lineup, it edges the B3 on balance but can’t quite match the Meteor’s treble elegance.

In the value maze, availability hurts: outside Japan, alternatives like a Dusk + DSP bundle or the Kiwi Ears Astral may be easier grabs and offer a bit more warmth and sub-bass. Still, Aqua stands out as one of Moondrop’s better-tuned releases—technically solid, musically lively, and highly competitive if obtainable. Verdict: a high recommendation for those who enjoy a crisp, airy tilt; roughly 3.5–4 stars overall.

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.

Youtube Video Summary

Japan-only limited edition revision that keeps the 2DD+4BA architecture, the same unboxing, and swaps in a mirror-aqua faceplate that’s a fingerprint magnet plus a transparent shell to show the internals. The new soft 4-core fabric cable with interchangeable 3.5/4.4 plugs and a working chin slider keeps microphonics lower than most fabric leads, though they’re not gone. The shell runs a bit large yet stays snug and comfortable; those with small ears should test a Blessing 3 fit first.

Tuning shifts toward more sub-bass and lower mids with less lower treble, trading the original’s brightness for a more relaxed, less clinical balance. The focus is a natural midrange—fuller male vocals and smooth upper mids for female vocals—while the upper treble is slightly rolled off, which some will find easier on the ears. Resolution and micro-detail remain strong with solid imaging; the soundstage is about average.

Versus Blessing 3, Aqua adds bass and body and tames shout; against Dusk Analog it’s similar, but Dusk can swing warmer with the DSP cable; compared with Meer SL224 the Aqua’s bass is bigger/slower with more natural vocals, while the YU9 Que brings brighter treble extension and broader versatility. Recommended if natural, vocal-centric tonality is the goal rather than basshead slam or sparkling top-end. Strong revision, but limited availability and pricing dent the value next to rivals, so it earns a two-star recommendation on value.
