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 BGVP NS10 is a 10-driver hybrid IEM (2DD + 8BA) built in lightweight aluminium shells with MMCX connectors and interchangeable screw-in tuning filters. Reviews consistently highlight the solid machining, low weight and comfortable, ergonomic fit, as well as the modular 3-in-1 cable and generous accessory set, which is notable at its roughly $170 street price. Other impressions point out that build quality and long-term comfort are strengths, making the NS10 a practical daily-use option rather than just a showpiece.
Tonally, the NS10 follows a neutral-bright, mildly V-shaped tuning that sits fairly close to a Harman-style target, with modest boosts in bass and lower treble. Bass is elevated slightly north of neutral but remains controlled and well-textured, giving kick drums and bass lines weight without masking the midrange, while vocals sit relatively forward and clean rather than recessed. The treble region is a clear focal point: lower treble energy delivers strong clarity and microdetail with good air, but several reviewers note that it can be on the lively side, so treble-sensitive listeners may prefer the more relaxed filter options.
Where the NS10 stands out in its price band is technical performance: multiple reviews emphasise above-average resolution, precise imaging and clean separation, with a stage that is more about well-defined placement and height than sheer width. These traits, combined with the configurable filters, make it attractive for listeners who prioritise detail retrieval and a revealing presentation over a relaxed, warm balance. Considering the competitive $150–$180 segment, the NS10 offers strong performance and tuning flexibility, but its energetic treble and the density of capable rivals mean it is better viewed as a very competent mid-tier option rather than a category-defining outlier in overall value.

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
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.

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
The BGVP NS10 Pro combines a solid metal shell, mmcx connection and modular cable with a lean, upper mid focused tuning. The dual dynamic drivers deliver a clean, punchy bass response with strong slam and sub bass extension that stays out of the midrange, so the presentation feels tight rather than boomy. Midrange is clear, forward and highly detailed, but the 2 to 6 kHz region carries extra energy, so female vocals, violins, flutes and bright piano notes can come across a bit too intense for listeners who do not already enjoy a very present midrange.
Treble sits in a sweet spot between dull and piercing, giving cymbals and high frequency detail good presence without stealing the show or turning harsh. Overall detail retrieval is strong for a mid fi set around 300 dollars, with good separation that keeps instruments distinct even in busy passages. The tonal balance ends up quite lean and energetic rather than warm, which suits cleaner, gentler recordings more than already hot or compressed mixes.
On the technical side the NS10 Pro offers impressive imaging with precise spatial cues and a stable sound field that makes positional information easy to follow, while the soundstage is respectable though not class leading. The punchy dynamics and constant sense of bass impact add excitement, but the elevated upper mids reduce long term comfort at higher volumes and limit genre versatility compared to more relaxed alternatives such as the AFUL Performer models. Overall, this is an engaging, detail forward hybrid for listeners who prioritise clarity, speed and slam over warmth and a laid back presentation.
