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 Softears Volume S emerges as a standout vocal specialist under $500, often described as a "mini studio 4“ due to similar frequency graphs. However, it trades some treble detail for superior scaling and a heightened focus on the mid-range, particularly vocals, while adding a touch more mid-bass oomph. This treble reduction allows the music to breathe, creating a more immersive and musical experience that pulls the listener deeper into the sound compared to the Studio 4, without sacrificing a sense of space or leaving the bass and treble feeling inadequate. Though not bass-heavy or treble-head oriented, the low-end provides enough thump and the highs enough air to avoid sounding lean or dark, resulting in a presentation that's slightly less technical and balanced than the Studio 4 but excels in vocal delivery and engagement.
A key feature is the tuning switch which boosts upper mids and treble while lowering the bass, effectively transforming the sound into a cleaner, more technical version of Harman 2019, even surpassing the Studio 4 in detail retrieval in this mode. However, this boosted configuration can sound shouty, lean, and overly clinical for many preferences, lacking the thickness of the stock tuning and scaling less effectively at higher volumes. The stock tuning, preferred for its vocal prowess, truly comes alive with increased volume. The included clear tips are recommended for a slight treble lift and comfort, and the bundled USBC adapter adds a subtle amount of sub-bass rumble, though the low-end remains clean and controlled, reminiscent of leaner sets like the Pilgrim, not providing heavy slam.
While the Studio 4 remains a solid, well-balanced all-rounder, especially on sale around $350, and alternatives like the EM10 (more detailed), Supermix 4 (better value), the Volume S carves its niche with exceptional vocal performance at higher volumes using the stock tuning. Its main drawbacks involve the confusing switch design (requiring opposite positions on each earpiece for the same tuning with no clear indicators) and the pricing debate; using non-branded drivers suggests a more appropriate price point would be $200-$250 rather than $300. Despite these quirks and marketing claims about the passive radiator's role (its actual impact being debatable), the Volume S delivers a great sounding, flexible IEM offering distinct sonic profiles based on volume level and switch position.

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.

Youtube Video Summary
Softears Volume S follows the 2022 Volume and steps into a fiercely competitive ~$320 bracket with a seriously premium kit: a gorgeous leather case, modular screw-on terminations, both standard and Ultra Clear eartips, IM booties, and tiny screwdrivers for the on-board potentiometer. The stealthy black resin shells with exposed carbon-fiber faceplates feel solid and fit well thanks to slim nozzles; just note there’s no nozzle mesh. The big caveat is the cloth-sheathed stock cable—ergonomically nice but with heavy microphonics. Two tunings are selectable: low-impedance (≈10Ω) and high-impedance (≈31Ω). The low-impedance mode is the keeper; it’s easy to drive yet sensitive to source output impedance, so a dongle under 1Ω is recommended to avoid unintentionally shifting the tonality.
In low-impedance mode the signature is neutral-natural, a flatter, more mid-centric take on “new-meta.” Bass offers quality over quantity: textured, punchy, and responsive without tipping into basshead territory. The mids are the star—clean, warm-tinged lower mids give male vocals body while female vocals sit forward without shout, keeping timbre natural. Treble is smooth, airy, and non-fatiguing, avoiding metallic glare while preserving sparkle. Technical performance is confidently above average for the price: imaging & stage feel wide and well-layered, with good separation and resolution that rewards attentive listening without forcing it.
Positionally, think “Kato upgrade”: smoother treble, better bass texture, and a refinement that many will prefer. Versus spicier rivals like DaVinci, Project Meta, Dusk DSP, or Mega 5 EST, the Volume S sounds more controlled and “correct,” trading some slam and upper-air fireworks for coherence and timbre. It won’t thrill bass lovers, treble heads, or detail chasers seeking a spotlighted presentation; everyone else gets a superb all-rounder that feels benchmark-worthy—the HD600/650 vibe for IEMs. Verdict: you should buy this if a do-it-all, neutral-natural tuning is the goal; just mind your source impedance and consider swapping the cable to kill the microphonics.

Youtube Video Summary
The Softears Volume S at $320 sets a new tonal benchmark for IEMs in its price range. It arrives in solid packaging featuring a zippered carry case (a bit large but functional), protective earpiece pockets that might feel overkill for some, and two excellent sets of ear tips – including Softears' own highly-regarded Ultra Clear tips. Build quality is generally fantastic, highlighted by a resin shell, a comfortable paracord-style cable with a low-profile, user-swappable termination system, and recessed 2-pin connectors. While the aesthetics might feel a bit old-school to some, the fit is comfortable and stable due to its semi-custom shape and longer nozzle, making it secure enough for sleeping. A small screwdriver-adjustable tuning switch offers a secondary, brighter Harmon-like sound signature, though the default tuning is preferred.
The default sound signature is a warm-tilted neutral, delivering exceptional natural timbre and tasteful bass boost. This bass stands out for its exceptional physicality – punchy and impactful without being overbearing – alongside articulate sub-bass that’s easy to follow. Combined with well-defined transients, particularly in the upper-midrange, it creates a satisfyingly rich and dense presentation. While spatial effects and imaging are competent but not standout, the overall tonality and bass quality are remarkably refined. Comparisons show it offers a better tonal balance and bass control than the bassier Dunu DaVinci, significantly more body and richness than the brighter, thinner Moondrop Blessing 3, and trades blows with the Moondrop Dusk – the Volume S providing superior density and mid-bass presence versus the Dusk's more open, spacious presentation.
Ultimately, the Softears Volume S earns a full five-star rating. It might not be the absolute most technically dazzling IEM, but its fantastic tonal balance, unique bass physicality, and overall refinement make it a compelling choice. For $320, it delivers a sound signature that feels just right – rich, satisfying, and universally appealing – challenging more expensive offerings and establishing itself as a top contender in its class.

Youtube Video Summary
The Softears Volume S delivers a fantastic hybrid sound in its low impedance mode, characterized as a warm neutral tuning with a lush note weight, good bass punch without bloat, and a slight upper-midrange emphasis that makes vocals pop. This signature translates exceptionally well across both music listening and competitive gaming, offering great separation, layering, and phenomenal imaging for precise positional awareness. While engaging and non-fatiguing, gunfire and intense effects in games like Apex Legends can sometimes feel on the verge of shouty or slightly occlusive during chaotic, high-level scenarios, lacking that last bit of air and resolution in the upper mids.
Gaming performance shines across multiple titles. The Volume S provides outstanding depth perception and accurate imaging for Apex Legends slides and light footsteps, excels in Valorant with its separation and verticality, handles the chaos of Call of Duty exceptionally well, and proves to be a top recommendation for Fragpunk due to its loud, precise, and easily trackable footsteps. The smaller resin chassis offers great comfort and ergonomics, especially for those struggling with fit, though it doesn't feel quite as premium as some metal competitors in its price range.
Significant drawbacks include the utterly dismissed high impedance mode tuning, deemed "absolute garbage" and a headache for gaming, and the fragile tuning mechanism itself, prone to easy damage. The included shoelace-style cable is functional with a removable termination but not a favorite, and the unboxing experience, while decent with a pleather case, extra termination, and two sets of silicone tips, is fairly typical for the price. Ultimately, the Softears Volume S stands as a killer all-around IEM when locked into its excellent low impedance mode, highly recommended for its crossover appeal despite the useless tuning switch and build quibbles.

Youtube Video Summary
The Softears Volume S offers a dramatic transformation through its impedance switch, requiring a tiny screwdriver to toggle between low (9.8 ohm) and high (31.2 ohm) modes. The low impedance mode is described as painfully clinical, bland, and annoyingly sterile across all tested amplifiers. It’s reminiscent of the disliked original Volume model, lacking any enjoyable tuning despite EQ attempts. This mode only suits listeners craving absolute neutrality, offering little musical engagement.
Switching to the high impedance mode completely revolutionizes the experience. It becomes relaxed, unoffensive, and remarkably smooth, with notes possessing a lingering, church-like resonance that adds emotional depth. This mode presents music with a spacious, uplifting quality and a subtle chest-felt pressure during resonant passages. However, it demands quality amplification to shine and benefits from tip-rolling; the included sticky liquid silicone tips enhance the signature, though alternatives like Azla SednaEarfit can tweak the response. Comfort and build are excellent, though the fabric cable exhibits some microphonics.
Priced around $300, the Volume S earns a cautious recommendation primarily for its stellar high-impedance performance. It requires tinkering with tips and sources to reach its potential and faces stiff competition in its price bracket. While not an outright class leader, it’s a significant upgrade over the original Volume. The package includes a luxurious case, multiple tips, and a branded USB-C adapter, reflecting Softears' typical attention to detail. Just keep it locked in high-impedance mode.

Youtube Video Summary
The Softears Volume S delivers a distinctly colored sound signature with significant boosts in two key areas: the bass and the upper mid-range. Its bass profile is uniquely elevated up to around 300Hz, resulting in a physical, heavy, yet well-defined low end that impresses with substantial note weight and attack, appealing even to bass enthusiasts. Vocals cut through clearly due to the upper mid-range boost, but this tuning comes with a trade-off: a noticeable sense of hollowness and a narrower soundstage that can feel congested on certain tracks, creating a love-hate relationship with its presentation.
The treble offers a safe, natural, and polite character, providing adequate detail without excessive brightness or roll-off, though it may lack sparkle for some listeners. Technically, the Volume S performs at a level comparable to the Moondrop Blessing 3, excelling particularly in the incisive attack and substantial weight behind each note. When compared to competitors, the Volume S edges out the Tea Pro in bass quality, separation, and natural timbre, though the Tea Pro offers a wider stage. Against the Blessing 3, the Volume S trades openness and cleanliness for a more fun, bass-forward and impactful experience. It also presents a more balanced signature than the brighter, more treble-focused Kiwi Ears Astral.
Ultimately earning an A-minus rating, the Volume S is highly recommended for those seeking exceptional bass quality and a fun, colored tuning. However, it might not suit listeners prioritizing a wide soundstage, a neutral signature, or a bright, sparkly treble with forward micro-details; these listeners are advised to audition first.

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.
