Letshuoer S15 VS Artti T10

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

Artti T10 hits the budget planar brief with a thoughtful package: a sturdy hard carry case, six pairs of tips (S/M/L in both standard and wide-bore), and a supple 4-wire cable offered in 3.5mm or 4.4mm. The cable behaves well, but the chin slider is frustratingly stiff. Build is reassuring—polycarbonate shells with a UV treatment, metal mesh at the nozzle, and sensible venting—while remaining exceptionally light. It asks for a bit more juice than a phone; a small dongle DAC is recommended. Comfort is solid for average ears, though the “tiny ears test” fails as jaw movement can break seal. Styling leans retro hearing-aid; the “Council of Ladies” gave it a unanimous thumbs-down.

Tonally, this is a mild V-shape with excellent sub-bass extension and punch, speedy planar bass that stays clean, and mids that are accurate with a hint of female-vocal forwardness. Treble is clean, smooth, and non-fatiguing, walking the harmonics tightrope without glare. Technicals impress across the range: clear microdetail, crisp transients, confident separation, and a stage that places instruments naturally with good stereo imaging. It handles electronic bass drops, rock kick drums, complex vocals, and fast acoustic picking with equal ease—planar speed without the usual edge.

Against peers, T10 reads like a slightly more relaxed Letshuoer S12 at a fraction of the cost; brighter and more energetic than Letshuoer S08 and Hidizs MP145, and more lively than the more neutral NiceHCK F1 Pro. It’s a clear step up from the budget Luna, especially when found on sale. Accessory parity is strong, ceding only to sets with modular cables (S08/S12 Pro). Verdict: at $75 MSRP this earns “This is brilliant” on the Audio Amigo scale, with a standing upgrade to “You should buy this” if available around $50. A top-tier value pick for anyone wanting a mature, engaging planar—so long as small-ear fit and the looks aren’t deal-breakers.

Youtube Video Summary

The Artti T10 is a 14.2 mm planar dressed in an unapologetically industrial shell—textured, raw, almost “1980s test-gear” chic. In the box: case and a solid cable with a 3.5 mm or 4.4 mm choice at checkout (no modular tips to swap later). The shocker is the price: $69 with a 15% coupon, a package that feels like it should sit closer to the $200–$250 crowd. One big knock: a paper insert from the retailer pushing incentivized 5-star posts for $10—hard pass on that practice. Aesthetics aside, the overall presentation screams “budget done right” without pretending to be luxury.

Sonically, this set hits like a grown-up S12: wide staging, crisp detail, and a sweet, forward treble that stays exciting without turning glassy. Bass comes in clean and controlled, vocals land with satisfying color, and the tuning keeps tracks engaging across genres—laid-back when the mix calls for it, energetic when it gets heavy. It scales with source (surprisingly happy on tubes like WA7), and tip-rolling pays off—deep-seal options (Render, Dunu SS, XELASTEC-style) add presence and grip. Under $100, it’s easily a top-five contender on sonics alone. Final word: 9/10 for sound; would edge closer to perfect with a modular plug system and a better tip spread, but as a wide, detailed, insanely good-value planar, the T10 absolutely delivers.
