Tanchjim Oxygen VS Tanchjim Origin

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.

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.

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

Origin aims to update the classic Oxygen recipe with a mid-bass lift and a long bass arc, but the execution pushes the upper mids (3–5 kHz) too high and adds an oversized air/upper-treble shelf. The net effect is a neutral-bright balance where mids lose weight and naturalness, while the supposed sub-bass roll-off is mostly a masking effect from the hot top end.

The bass arc itself is solid, yet it stays masked unless another 1–2 dB is added around ~50 Hz; vocals come across lighter and faster rather than organic, and the extra air sounds more like artificial sheen than true resolution. With so much top-end energy, the stage flattens into the head and becomes fatiguing at moderate volume, undermining the otherwise capable driver and leaving little genre flexibility compared with Oxygen.
