Truthear Pure VS Letshuoer S12 Ultra

Youtube Video Summary

The Truthear Pure keeps the $90 hybrid recipe of the Hexa (3BA+1DD) and most of its shell geometry, but tweaks details: a slightly smaller nozzle eases fit for those who struggled with Hexa, while a thicker body changes how it sits against the antitragus. Accessories are sensible—the pocketable soft pouch and three styles of ear tips help dial in seal and stability—though the bold logo and faint channel markings won’t win style awards. Overall comfort is compact and easy, with fit security largely dependent on tip choice rather than ear-conforming contours.

Sonically this is a shift from Hexa’s laser-neutral baseline to a warm-neutral flavor: ~1–2 dB more energy from 1 kHz down adds body and density, while slightly pulled-back upper mids/treble relax the presentation. Stage size and separation aren’t the selling points, yet the treble execution is impressively clean and controlled for the price, avoiding the congestion feared from early listens. Bass remains not the star, but attack is snappier and kick definition more satisfying than on Hexa, making drums feel better outlined without abandoning neutrality.

Think HD600 vs HD650: Hexa reads brighter, airier, and a touch more “technical,” while Pure is fuller, warmer, and more relaxed—arguably the more mature tonality. For contrast seekers, the Jazir/Z Reviews Defiant hits harder with a lively V-shape; to split the difference with extra low-end and micro-contrast, the AFUL Explorer fits. As a sub-$100 choice, Pure lands as a five-star set: not a technical monster, but a beautifully tuned, dense take on neutral that stands shoulder-to-shoulder with Hexa rather than replacing it—pick Hexa for openness, Pure for tone and treble refinement.

Youtube Video Summary

Truthear Pure arrives as a $90 1DD+3BA hybrid with a solid accessory set: postcard, soft pouch, six pairs of silicone tips plus foam. The non-modular cable is notably soft, tangle-free, low in microphonics, and the chin slider actually stays put. Shells are semi-transparent 3D-printed resin with a grooved faceplate, a vent, and a nozzle lip that keeps tips secure; there’s a recessed 2-pin connector. Size is only slightly larger than Hexa, but comfort is similarly excellent—low-profile, secure, and easy for long sessions.

Sonically, Pure shifts firmly into warm territory. Bass is abundant with strong slam, yet its slower decay and “glide” into the lower mids introduce a thick, relaxed presentation that can cloud mid-range clarity and leave vocals a touch hazy; the upper-mids sit a bit too laid-back for the bass level. Treble is safe, smooth, and non-fatiguing rather than airy. Technicals are middling for the class—imaging decent, detail behind more incisive sets. Versus Hexa, Pure adds bass and impact but loses the Hexa’s clean, neutral midrange; compared with Moondrop Aria 2, it’s the “too warm” side of warm-tuned. Best suited for listeners who want a cozy, laid-back signature; not ideal for clarity seekers unless EQ is used to trim the low-mids/bass. Final verdict: 3/5 stars—comfortable build and enjoyable smoothness, but the warmth dominates the balance.

Truthear Pure follows the beloved Hexa with a smarter twist on neutrality: a hybrid 1DD+3BA at $90 that keeps the sturdy 3D-printed shell, slightly chunkier but similarly comfortable. The package is generous—three pairs of “thick” tips, three “thin,” plus foams—along with a much softer, less tangle-prone cable (still a fixed termination) and a soft leather pouch that’s actually pocket-friendly. Build, fit, and accessories punch above price, making this feel more premium than the tag suggests.

Sonically, Pure takes Hexa’s neutral core and downtilts it: a touch more lower-mid energy for weight and body, with the Hexa’s brighter colorations eased back. The result is a warm-neutral, enveloping, and non-fatiguing presentation—vocals and instruments gain richness without mud, and timbre/decay stay natural rather than dark or blunted. Think of the duo like HD600 vs HD650 for IEMs: pick Hexa for cleaner/brighter clarity, pick Pure for fuller, relaxed musicality. Choose Pure if a superbly executed warm-neutral tuning, long-session comfort, and broad genre versatility are priorities (great as a first “do-it-all” IEM). Skip it if a crisper, more analytical, or treble-forward edge is needed—the Pure presents detail naturally rather than pushing it. Either way, Pure carves meaningful space beside Hexa: neither redundant nor straying too far from true neutral, just the right amount of warmth done right. (Also, a white Pure would be fun—name kinda begs for it.)

Youtube Video Summary

Truthear Pure brings a warm, bass-impactful presentation from its 1DD+3BA setup, but the rest feels like it’s under a blanket. There’s a noticeable 2 kHz hump, then the upper range ducks hard past ~8 kHz, leaving the sound veiled—like three comforters thrown over the music. Great for bass-centric tracks (think Arcane S2 remixes), yet dull and somehow fatiguing at the same time. The shells look cool—semi-transparent with a heatsink-style back—and the stock cable is soft and supple but fixed 3.5 mm. Accessories are classic Truthear: small leather pouch, tip array, and a waifu postcard. Listed around $89 (feels more like $50 value).

The real curveball is the imaging and stage. On 3D test tracks that should sweep smoothly around the head, motion skews and snaps—front/back depth behaves weird and timing feels off. It’s the kind of tuning (or implementation) that begs for EQ just to “open it up”. For listeners who want warmth + bass and the bunny-girl aesthetic, this will scratch the itch. For a cleaner, properly integrated 1DD+3BA experience, alternatives like Defiant make more sense, especially at a similar price. Net: an acceptable set for bass enjoyment, but with odd staging and a rolled-off, veiled top end that keeps it off the must-buy list.
