Youtube Video Summary
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.

The DITA Prelude aims for a mild V-shaped presentation that stays easy on the ear: bass has a gentle lift, mids stay clean, and treble adds air without harshness. DITA itself describes the Prelude as mild V with an emphasis on technicalities, which lines up with its relaxed yet open tonality . Treble extension and perceived headroom are standouts at the price, helping stage and layering feel a notch above typical entry-level fare .
Hardware is straightforward: a single 10 mm dynamic driver with a composite diaphragm and dual magnets, plus dual-volume venting for control and consistency . The metal shell is compact and sturdy, and the 0.78 mm 2-pin interface keeps cable options open if you want to swap later . Detail retrieval is good for the bracket; micro-detail won’t challenge kilobuck sets, but separation holds up well in busy tracks.
Value is helped by the bundled ANTE USB-C DAC/amp dongle, which pairs neatly and removes source guesswork for newcomers . Bass is tastefully elevated rather than boomy, so bassheads may want more slam, but the Prelude’s balance and treble smoothness feel well judged for long sessions. Street pricing sits around $159, making it an easy recommendation for a first serious single-DD IEM .

The Letshuoer S12 Ultra continues the brand’s planar lineage with a 14.8 mm planar-magnetic driver in a compact metal shell. Notable upgrades include a 392-core silver-plated cable with interchangeable 3.5/4.4 mm plugs and even a bundled DT01 Pro Type-C DAC cable in some packages, positioning it as a self-contained portable solution at an MSRP around $169.
Tonally, the Ultra aims for a lively U-shaped balance common to prior S12 variants—crisp upper-treble energy with solid bass presence—while early impressions from show-floor demos frame it as the most refined take yet. That aligns with the S12 family’s reputation for strong resolution and a brisk top-end; the original S12 was praised for technical performance albeit with a brighter tilt, context that helps set expectations for the Ultra’s direction.
As with many planars, the S12 line can benefit from competent source power to realize dynamics and control; community reviews note the Ultra responds well to suitable amplification. Staging remains more intimate than expansive compared to some hybrids, but imaging and micro-detail are competitive at the price, making the Ultra a pragmatic sub-$200 pick for listeners who value clarity and transient speed over warmth.

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.
