TWISTURA WoodNote VS Letshuoer S12 Ultra

Youtube Video Summary

TWISTURA WoodNote is a single dynamic-driver IEM that leans premium in presentation: compact metal shells with recessed 2-pin, proper venting, and a smooth, durable finish. The kit is generous—multiple eartip sets, a plush case, and a supple modular cable with a twist-lock plug (swap to 4.4 mm if needed) plus a firm chin slider. Its party trick is the trio of tuning nozzles—Normal, Vocal, and Instrumental—that subtly shift energy through the mids/upper-mids; Normal comes across the most balanced, while Vocal and Instrumental add presence and bite. MSRP hovers around $189 (previously spotted lower), and availability is broad through the usual audio retailers.

Tonally, this set pursues a warm, mild V-shape with easygoing musicality: full mid-bass, rich lower mids, and a smooth, inoffensive treble. There’s a touch of metallic timbre at times and the top end trades precision and “air” for comfort, so micro detail is merely decent. What stands out is the sense of space—a slightly “hollowish” stage that feels open without turning sharp—and an overall engaging, fatigue-light listen. Nozzle rolling meaningfully nudges its character, but the core signature stays clean, fun, and broadly genre-friendly.

Against peers, AFUL Explorer offers more technical clarity, air, and bass control, while WoodNote counters with better build, packaging, and tunability. Versus sets like Binary Chopin, expect thicker upper mids from WoodNote but less etched detail; compared with “Volume S,” the similarity in warmth is clear, though WoodNote’s treble is less incisive. In a crowded ~$180 bracket (think JM1, ZiiGaat Lush, Cadenza, etc.), this feels like a dark-horse: not the most unique or analytical, yet strikingly well-rounded, gift-ready, and satisfying for DD-timbre fans who value smoothness over scrutiny. Final word: a solid 83/100—competitive at MSRP and an even sweeter pick if found closer to that lower street price.

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.

TWISTURA WoodNote comes in on the pricier side at $180, touting a wood diaphragm and a surprisingly excellent cable—arguably the nicest of the bunch. The shells fit well and feel thoughtfully built, though the chin slider is basically decorative without a DIY fix. Ergonomics aside, this package reads premium where it counts: comfort, accessories, and overall presentation.

Sonically it’s a lively, V-shaped tuning with a bit of lower-treble/presence lift that pushes vocals forward without tipping into sharpness or sibilance. Imaging is tidy with a decent headstage; the bass isn’t the tightest or most incisive among peers, but the whole presentation stays engaging and balanced enough for long sessions. More energetic than a safer, neutral set yet less fatiguing than the spicier options in the round-up, WoodNote earns a confident B-tier placement—an easy pick for listeners wanting a brighter, livelier single-DD that still plays nice over time.

Youtube Video Summary

TWISTURA WoodNote shows up with a surprisingly premium kit: a super-nice box, a plush purple case, chunky stock cable (beefy and good-looking, though the earhook angle begs a quick heat-gun/hair-dryer fix), and interchangeable nozzles labeled Standard, Vocal, and Instrumental. The shells are small and comfy, with a soft grip fin that makes insertion easy. Under the hood: a single 10 mm dual-cavity DD with a “revitalized wood diaphragm” pitch. The accessory flex continues with four custom tip trays—including sticky/tacky clears and wide-bore options—so there’s plenty to tune before touching EQ.

Sonically, this is a big-stage, high-energy single-DD that favors imaging and note weight. With the Standard nozzle, the balance clicks: bass hits confidently without smearing, mids stay forward/focused, and treble extends cleanly without turning spicy. The Instrumental nozzle pushes air and sparkle but tips into too-much-treble territory; the Vocal option feels “off” versus Standard. Drive is easy, and character shifts nicely with source—clean/linear, warm, even tube bloom. Played too loud, the midrange can get shouty; back off a couple dB and it snaps back to “ahh, that’s right.”

Value check: discovered around $180, which feels like a cheeky sale price on a set that performs closer to $220. The cable angle quirk is fixable, the nozzle filter deltas are subtle (stick to Standard), and the accessory spread is downright generous. Net take: a solid, fun, aggressively big-sounding single-dynamic that earns full marks for the money—great for music, totally game-ready, and easy to recommend if a lively stage and crisp imaging are the brief.

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.
