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.

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 MYER SLIIVO SL224 is an eight-driver hybrid built around 2DD+2BA+4 micro-planar units with a 36 Ω impedance and 108 dB sensitivity, positioned at an MSRP around $269.99 (often on sale near $230). This configuration, including 10 mm and 6 mm dynamic drivers, suggests an intent toward a clean, extended response rather than a bass-dominant tuning. Specs & pricing: 2DD+2BA+4 micro-planar, 10 mm + 6 mm DD, swappable 3.5/4.4/Type-C cable, sale price ~$229.49, regular $269.99.
Subjective reports converge on a balanced/neutral tonality with energetic yet controlled low end from the dual-DD array, lively mids, and an airy but not piercing treble. Mobileaudiophile characterizes bass as fast and powerful with engaging mids and treble, yielding a coherent, never-boring balance; this aligns with the SL224’s technical focus rather than coloration. Tonality & balance references: balanced tuning, lively mids, airy treble; bass praised for speed and control.
Technical impressions emphasize dynamics, detail retrieval, and cleanliness, with community notes calling out tight, quick mid-bass and respectable separation; limitations include occasional midrange forwardness that can mask other bands on some tracks and a stage that reads more precise than expansive. These traits point to strong value in the ~$230 bracket for listeners prioritizing clarity and midrange presence over sheer sub-bass weight. Community impressions & caveats: tight mid-bass, good dynamics; mids can get a bit forward depending on material.

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.

Youtube Video Summary
The MYER SL224 is a stylish tribrid (2DD + 2BA + 4 microplanars) coming in around $270, shipped with a decent 4-core cable featuring 3.5 / 4.4 / USB-C interchangeable plugs, a zipper case, and three ear-tip sets (regular silicone, SpinFit-style silicone, foam). Build is eye-catching thanks to a real mother-of-pearl faceplate; the shell is on the larger side with a universal-custom shape that sits comfortably for long sessions, though smaller ears should test fit first. Cable behavior is mostly cooperative (functional chin slider, slight memory), and overall accessories feel thoughtful for the price.
Tonally, SL224 targets a clean, clinical presentation: sub-bass carries the weight while mid-bass stays nearer to neutral, which can read a touch lean unless paired with a warmer source (tube or similar) to add body. The midrange tracks neutral until the upper-mid / lower-treble rise, boosting female vocal harmonics and air; some may find this area forward, yet it avoids the usual micro-planar harshness. Treble is well-extended and energetic, if not the smoothest—there’s a hint of disconnect around the pinna gain—but this nit shows mainly against sets two to three times the price. Technical chops are a highlight: resolution rivals class standouts (think AFUL P7 territory), imaging is tidy, stage is fairly wide, and it earns a strong nod for competitive gaming.
Against peers, CK2V hits harder down low but dips mid-bass and feels less even up top; AFUL P7 is more balanced yet less flattering to female vocals and trickier in treble; “Dusk” (DSP) delivers better bass and a warmer tilt; “Brain Dance” is flashier but far sharper; Moondrop Meteor tracks a similar tonality with smoother highs and a mid-centric lean—an easy upgrade path if this signature clicks. Recommendation is clear: pick SL224 for a mid/treble-focused set with standout detail and clarity; skip it if sensitive to upper-mid energy or chasing a warm, bass-rich tuning. For value, this feels underrated and distinct in a meta-heavy market, earning a solid three-star recommendation.

Youtube Video Summary
The Meyer Audio SL224 comes in around the $269 mark with a very complete package: a comfortable 3D-printed resin shell, genuine shell-inspired faceplate material and a soft, modular cable that feels like one of the better cables at this price point. Fit is easy and secure, isolation is decent, and the modular terminations (4.4 balanced, 3.5 single-ended, USB-C) make it a practical daily driver for different sources. Overall build, design and accessories feel thoughtfully put together for this price range.
Sonically, the SL224 leans toward a neutral, vocal-focused tuning with highlighted upper mids and sub-bass. Bass is more sub-bass centered, adding a solid foundation and extra engagement on tracks with low-end emphasis, but mid-bass and low mids are relatively restrained, which can make the presentation sound a bit thin and bass-light depending on the library. Midrange clarity is strong and vocals in particular come across as natural and expressive, yet the combination of forward upper mids and lighter note weight means some listeners may wish for more warmth, richness and body, especially when compared with fuller, more balanced sets at and below this price.
Treble is where the SL224 really shines: the micro planar array delivers excellent treble detail and extension without slipping into metallic or unnatural timbre, adding air and micro-nuance to the presentation. Technical performance is a clear strength, with precise imaging, clean separation and solid layering that place it among the stronger options under $300, even if soundstage width itself sits around average. While other sets like 61T, Da Vinci or Volume S may offer a more balanced, richer and smoother overall tonality for many listeners, the SL224 stands out as a compelling choice for vocal lovers who prioritize clarity, treble detail and technical performance and who don’t mind trading some warmth and bass weight for that mid-centric focus.

Packaging overdelivers: a modular cable with 3.5/4.4/USB-C and an included dongle that gets loud enough, seven pairs of silicone tips plus foam, and a small zip case (nice but tight). The shell looks premium with a depth-effect faceplate and a metal nozzle (≈6.1 mm lip); fit is snug though potentially big for smaller ears. Build and accessories feel thoughtful at the price, with only a slightly rubbery cable texture to nitpick.
Tuning is a smooth, vocal-focused, meta-inspired balance: refined mids, a friendly yet detailed top end, and a clean, controlled low end. Bass quality is textured and separated but intentionally polite—not for hip-hop/EDM impact chasers. The midrange brings clear, natural tone without shout; both male and female vocals sit forward. The treble is the star: highly resolving, airy, and surprisingly non-fatiguing for the four micro-planars, avoiding metallic glare while adding tasteful sparkle.
Technically, separation and resolution impress, with a mild cohesiveness quirk where the treble detail outshines bass/mids. Versus peers: CK2V is more V-shaped and brighter-hot; SL224 sounds more natural. Moondrop Meteor offers smoother treble and mid timbre, but SL224’s bass quality and value punch back. Dunu Brain Dance is technically stronger; SL224 wins on tonality. SoftEars Studio 4 remains more lifelike/cohesive; SL224 brings more air and fun. AFUL Performer 7 is the better all-rounder; SL224 is for lighter-bass, vocal clarity. Kiwi Ears Astral is airier/more micro-detailed; SL224 plays it safer up top with more forward vocals. Recommendation: vocal lovers and treble-sensitive listeners wanting detail without sting. Not for bassheads or warm-tilted tastes. Final verdict: a confident 4/5 and the most compelling Myer release so far.

Youtube Video Summary
Final revision of the series brings a very coherent, slightly warmer presentation with treble pulled into safer territory and mids that feel a bit weightier. Ultra sits between the smoother S08 and the rawer S12 Pro, and it comes across a touch bassier than the graphs suggest. As a single-driver planar, it retains solid resolve and a natural, easy tonality that will suit most listeners, especially at the 169 price point.
Despite graphs looking similar to S12 2024, Ultra sounds smaller and flatter, with less transparency and dynamics. Soundstage is mainly left-right; height and depth are curtailed, so placement is not always in the right place on more spacious tracks. The smoother top end avoids harshness and makes long sessions comfortable, but the trade-off is reduced sparkle and air versus the 2024 tuning.
Versus budget planar standouts like KZ PRX, Ultra is a clear, smoother upgrade; versus S12 2024, it is the safer all-round pick but not as open or exciting. Dense mixes can nudge the bass toward a slight bloom and compress the center image. For most, this is the one S12 to buy; stage and transparency chasers may still prefer the 2024 version.
