Letshuoer S08

Broad agreement on the shape — warm, relaxed, bass-forward, never bright — with labels ranging from 'neutral done right' to L-shaped to mild U. About a quarter of the weight (Acho, listener, Goggie, briantbrain, two Reddit owners) hears that warmth as unbalanced, muddy or oddly humped rather than well judged.

“The S08 is a great example of neutral tuning done right, at least to my ears.”

thaslaya, Head-Fi

“Tonally, the S08 sports a warm L-shaped profile.”

“A well-built and beginner-friendly IEM held back by an unbalanced tuning.”

Goggie, Head-Fi (3.5★)

Sources split, unevenly. Most call the bass the S08's calling card — deep, dense, textured and the most dynamic-driver-like low end on a budget planar. A weighty minority, led by Super* Review, hears it as thick, poofy or bleeding into the mids, worst on busy tracks; a few find the mid-bass merely thin or so-so.

Sources split. Three-quarters of the weight hears a warm, full, natural midrange — weighty male vocals, no planar glare. The rest hears it as recessed or uneven: female vocals turning thin, fragile or occasionally harsh around a measured 3 kHz dip, or veiled under the bass.

The closest split in the record. Half the weight hears a smooth, refined, non-fatiguing top end that still has enough air and sparkle — a welcome break from planar glare. The other half hears it as dark, dull and short of air, losing detail on acoustic instruments. Owners add that tips swing it: wider bores open it up, and the wrong tips leave it veiled.

Sources split. A minority (Acho, cqtek, Headfonics, FreeWheelinAudioLuv2) hears a surprisingly wide, spacious stage for the size. The majority hears it as average to intimate — 'around the ears', small, even claustrophobic, and congested on complex recordings — which several tie to the warm, bass-forward tuning and flag for competitive gaming.

Sources split, unevenly. Most praise precise left-right placement and 3D imaging within whatever stage there is. About a third — Super* Review and Headfonics among them — hears instruments overlapping and separation slipping on dense mixes, especially in the midrange.

Sources split. The majority calls it the least technical of the budget planars — musical first, with micro-detail traded away for the smooth top end. A third (Acho, Audio Amigo, The Headphoneer, thaslaya) finds detail good for the price and presented without strain.

Agreement that the driver is quick — a responsive attack and clean decay that keeps fast bass lines separate — with macro-dynamic slam rated good rather than spectacular. Several note it improves with a stronger source.

“The driver just has this timbre and responsiveness that is immediate.”

MagnumPP, r/iems

“The planar speed gives excellent transient response and quick decay.”

Goggie, Head-Fi (3.5★)

“Dynamics are good, but not spectacular. The most dynamic contrast is in the bass region.”

Chris, The Headphoneer

Sources split. The majority finds the small, light shell easy to seal and comfortable for hours. A real minority finds it the opposite: the bulkier front edge presses on the tragus, the short nozzle needs tip rolling to seal, and long sessions hurt — one 2026 video calls the comfort 'dreadful'.

Sources split along a clear line. Reviewers, most on 2024 loan units, praise the CNC-aluminium shell, the tight tolerances and the modular screw-lock cable as a class above the price. Owners tell a different story over time: 15 distinct Reddit owners and several Amazon buyers report one channel fading, cutting out or dying within weeks to months — some on replacement units — commonly blamed on condensation in the metal shell. A long-term owner thread is mixed, with as many trouble-free sets.

Ordinary for a vented IEM — average at low and mid frequencies, with the right tips; reviewers range from 'about average' to 'surprisingly above average'.

“Isolation is surprisingly above average despite the heavy venting.”

baskingshark, Head-Fi

“For a vented IEM, the S08 has decent isolation performance.”

Meldrick, Headfonics

“Beyond fit, the isolation is about average.”

Love, Mobileaudiophile

Sources split. Two-thirds of the weight calls it outstanding at $99 — metal shell, modular cable, case, and a distinctive warm-planar tuning. A third disagrees: Super* rates it three stars and points bass lovers to the AFUL Explorer, Goggie and Headphones and Coffee prefer Letshuoer's own S12 family, and owners hit by failures call the durability poor for the price.
