Tanchjim Origin VS Letshuoer S12 Ultra

Youtube Video Summary

Tanchjim Origin gets the “Legendary” treatment for good reason: it’s a clarity-first single-DD that puts finesse over flash. The full-metal shells feel premium but can be slippery and a bit tricky to seat; expect some tip-rolling. Build notes include a semi-recessed 2-pin, a well-cut nozzle, and finish wear that can show with time—ergonomics are fine, just not as contoured as newer designs.

Tuning skews neutral and mid-focused: bass is clean with a light, non-exaggerated thump and controlled mid-bass, so no boom. The midrange is the star, while the treble brings smooth extension and a surprisingly refined sparkle. Technicals impress—pristine resolution, tidy separation, and standout imaging—but there’s no “thunder” down low; some listeners may notice a touch of brightness in the mid-treble. Swappable filters exist, yet their effect is subtle.

Reception has been bullish: Zeos called it obsessively neutral and nearly perfect; Timmy praised it as one of the year’s best with lovely, smooth treble; Super* Review rates it among the better sets under ~$260 while preferring the Chopin. In today’s field—with value picks like Tanchjim Bunny (to sample the signature cheaply) and modern darlings like Softears Volume S—Origin still stands as a refined, resolving choice under $300. Verdict: an A+ recommendation for listeners chasing cleanliness, mids, and imaging; bassheads should look elsewhere.

LETSHUOER S12 Ultra wraps up the S12 line with a 14.8 mm planar driver and a familiar metal shell in gunmetal or mocha. The housing is vented, comfy for long sessions, and solidly built with a flat 2-pin interface that grips tips well. The stock package is practical: a soft case, a fair tip spread, a braided cable with swappable 4.4 mm termination, and even a plug-and-play USB-C DAC that performs capably for on-the-go use.

Sonically, this set aims for a mild V-shape with tasteful tweaks that elevate it over prior S12 iterations. There’s a touch more sub-bass than the S12 Pro and a smoother 10 kHz zone, reducing fatigue while keeping upper-treble reach for air. The presentation favors balance over sparkle: detailed without the brittle edge many planars flirt with, and notably non-fatiguing over longer listens. Technical chops are strong for the class—clean, clear, and “planar-fast”—though instrument separation can lag behind pricier hybrids, and the topmost “crispy” sheen is slightly restrained.

On graphs and in practice, S12 Ultra reads as a refined take on modern planars—more bass weight, tidier 4–6 kHz, and better treble behavior than its siblings. Listeners hypersensitive up top may still prefer something like the S15 for a softer treble contour, while those chasing maximal separation may lean to sets like AFUL Performer 7 (with a spicier treble). With the usual planar caveat about unit variance and fit, this edition comes through as the standout of the S12 series: a clean, engaging, and genuinely high-value recommendation under $500.

Youtube Video Summary

Tanchjim Origin targets a balanced and clean tuning with a sprinkle of mid-bass. Dynamics come across smooth like the EA500LM but a touch cleaner; low-end is punchy, textured, and well separated, just not as tactile in attack as EA1000. The spotlight is vocals: female voices sound sweet, open, and extended without thinness or shout, though there’s less chest depth and a desire for a bit more sparkle. Stage feels tidy rather than expansive—EA1000 projects a more open headspace—so the Origin reads as “very correct,” not showy.

Treble is smooth, clean, and well-extended with no harshness; not Helios-level airy, but enough. Resolution sits close to EA500LM, while EA1000 delivers sharper transients and a slightly more resolving edge. Character map: Origin = balanced/clean, EA1000 = slightly bright/sparkly, EA500LM = warmest/bassiest. All three are mid-volume listens stock. With mods, EA1000 proves the most flexible and gains that engaging “special sauce” with more tactile bass and vocal energy; Origin is easier to dull or darken; LM can tip into too much bass with added damping.

In today’s market the Origin sits in a tough spot: EA1000 beats it on price, engagement, and mod scaling, while EA500LM undercuts it with better bass texture and value. With contenders like Nova, Chopin, Quintet, and Hype 2 swirling around, Origin makes the most sense if a balanced, smooth single-DD is wanted without a mid-bass scoop. The extra nozzles don’t meaningfully change things, and a price near $150 would feel far more justified. Otherwise, waiting for the next wave may be the smarter play.

Youtube Video Summary

The Letshuoer S12 Ultra comes through as the smoothest tuning in the S12 family— a sub-bass boosted all-rounder with quick transients and satisfying rumble that makes pop, hip-hop, and EDM notably fun. Technical performance sits around earlier S12 variants, but treble detail is dialed back a touch versus the OG/Pro in exchange for a more natural timbre and less “planar-bright” edge. It’s the bassiest S12 to date, hitting with better texture, impact, and extension, while keeping imaging crisp enough to stay engaging rather than clinical.

Tuning tweaks tame the upper range: a cut past 1.5 kHz and an 8–15 kHz dip ease shout and sibilance, with air returning via a lift around 15 kHz. Vocals sit a bit pulled back and the treble is the least energetic of the series, which helps long-session comfort—though brighter, heavily produced tracks or songs with little low-end can still sound peaky if pushed. Best results come at ~65–70 dB; tip-roll toward clear or bass-supporting tips to smooth the top and reinforce the lows, while avoiding brightening tips that exaggerate energy.

Versus peers, S12 Ultra feels like a bassier, less shouty take on Supermix 4/Nova and a slightly more V-shaped, punchier alternative to Defiant. It’s not a value monster for sheer detail compared with cheaper planars (T10, F1 Pro, etc.), but the payoff is a presentation that’s more musical, smoother, and easier to live with. For listeners wanting added slam without losing the S12’s speed and airy sense of space, this version offers the most enjoyable balance in the lineup.

Youtube Video Summary

Tanchjim Origin shows up with grown-up design, a slick logo, and a surprisingly nice stock cable—though it’s only 3.5 mm. Under the hood: a single dynamic driver and interchangeable nozzles. The “Dynamic” nozzle thickens the bass into a chewy, fun thump; the “Light” nozzle unlocks the magic—shockingly clean, near-neutral tuning with a tight low end. Tip rolling pays off (foam-filled silicone adds a touch of seal and snap), and the shells feel like proper adult jewelry. The carry case is comically huge, and the 2-pin posts are long, but build is otherwise dialed.

Sonically, Origin hits that “how is this this clean?” tier: vocals are dead-on, the treble stays smooth without bite, and the low end sits ~a hair north of flat for just the right weight. Staging isn’t stadium-wide—image arcs just behind the eyes—but layering, punch, and overall polish scream high-end without needing a mega amp. Swap to the Light nozzle, get a good seal, and it’s a full send: one of the best-sounding single-DD sets in this bracket, the kind that could still be recommended even at a higher tag. Call it a 9/10—dock a point for the non-modular cable and oversized case—but the tuning and refinement are spectacular for the price.
