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.

Clean balanced tuning done right. A better tuned MEGA5EST & MOONDROP Meteor with fuller low-end, and more treble extension, same tech, but more dynamic - also half the price. A Mega5EST with better vocals and dynamics but less smooth and airy. Low-end will be weak to some people and on certain tracks. Not the most unique sound since it's clean/neutral/balanced.

Smoothest S12 so far with fun sub-bass and good transients/dynamics. Slight v-shape, similar to the Defiant but a little more bassy. 1.5K vocal peak can be an issue on songs with no bass to cover it, but overall fine on most songs. Not as technical as OG S12/Pro, and not as good value vs cheaper planars, but trade of is Ultra is more refined, natural, and musical - I think the slight hit is worth it for a more enjoyable sound.
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.

The EPZ P50 is a tribrid with a 10 mm dynamic driver, two balanced armatures, and two micro planar drivers, implemented in a semi-open back shell and a three-way crossover—an uncommon configuration at this price tier. Listings and spec sheets place impedance at 20 Ω and sensitivity around 106 dB, with interchangeable 3.5/4.4 mm plugs and 0.78 mm 2-pin connectors, positioning it as a flexible daily-carry IEM near the $200 mark.

Subjectively, multiple reviews converge on a neutral-with-bass-boost presentation: sub-bass is tight and weighty when called for, mids stay clear and slightly forward, and treble is extended with extra energy from the planar tweeters. This yields a clean center image and articulate vocals without obvious mid-bass bloom, though the upper-treble emphasis can read “sharper” on some recordings.

Technical performance is competitive for the class: reviewers note solid imaging, above-average separation, and a stage that feels wider than typical sealed IEMs—qualities plausibly aided by the semi-open design and multi-way damping. Trade-offs include reduced isolation versus closed shells and a treble tilt that may fatigue treble-sensitive listeners at high volumes, but overall resolution and micro-detail retrieval punch above its price.

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.

Bass can be a little bit on the distracting side if you are looking for a neutral sound signature. Contrasty meta-tuning.
