Youtube Video Summary
SIMGOT ET142 pairs a polished CNC metal shell with a comfortable ergonomic fit and the LC7 modular cable including 3.5 mm and 4.4 mm plugs plus a case. Four interchangeable nozzles are provided, with revised geometry in production rather than just foam stuffing, and the foam can be added or removed for fine-tuning. Build and accessories feel genuinely premium for the segment.
The original gold/blue nozzles target a brighter, analytical upper range; the new black sits in the middle with a smoother treble line, and red is the most restrictive and warmest. With black, ET142 tracks close to Letshuoer S12 2024 in balance but remains more relaxed up top with slightly less resolve; with red, the tonality leans toward a clean, dynamic-driver style that edges out Timeless 2's Gold Leaf for ease of listening. Swapping foam in or out yields small but useful shifts without breaking the core signature.
As a package, this set prioritizes tuning flexibility and ease of listening over chasing maximum air and extension. S12 2024 stays the single-planar reference for sheer end-to-end resolution, but ET142 answers with a best-in-class shell and cable and friendlier options for treble-sensitive ears. For those wanting planar technicalities with a smoother top end, the black and red nozzles form a compelling, configurable choice.

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
SIMGOT’s ET142 pairs a planar driver with a PZT, delivering a bright-leaning, lively all-rounder that feels like a more mature, slightly more detailed take on the original S12 tonality. Treble is the surprise: it carries bite and air without the usual planar “sizzle”, landing closer to a well-implemented PZT sheen. Micro-nuance on cymbal work is improved, vocals are open, and technical performance is among the best heard from planars in this bracket. The 2 kHz region can read a touch shy, while overall treble sits above Harman, so expect sparkle and energy rather than warmth.
Volume and fit matter. At mid levels (~60–65 dB) the ET142 sounds engaging and airy; push past ~70–75 dB and the upper energy can turn fatiguing, with forward vocals and sharper highs on busy tracks. Tip choice is critical: treble-boosting tips can be too much, whereas wide-bore, smoother tips (e.g., “Senai Wide”) keep the top end in check. Both included nozzles measure and sound essentially the same—an opportunity missed for a second, tamer tuning. Genre-wise, rock, indie and slower pop benefit from the speed and air; dense electronic can edge bright, while K-/J-pop stays bouncy at moderate volume.
Bass is quick, punchy and clean with tight decay and excellent separation—don’t expect DD-level rumble or lingering reverb, but do expect balance and definition. Versus safer, more relaxed tunings (S8/S15/S12 2024), the ET142 is the more exciting pick; against neutral all-rounders (e.g., “Pilgrim”), it trades smoothness for air and sparkle; compared to sets like “Dusk,” it’s livelier with less treble fizzle but a more forward top end. At around $200, build is excellent (metal shells, braided cable) and the value strong—competing with some $300–$400 options. In short: choose ET142 for a bright, technical, energetic listen; skip it if a laid-back or dark tilt is the goal.

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 Simgot ET142 is a $220 planar–piezo hybrid that arrives like a mini system: full-metal shells, the chunky but well-behaved LC7 modular cable (3.5/4.4 included), a sturdy magnetic case, and four tuning nozzles (titanium stock, gold, short black foam, short red foam). Build is solid and venting prevents pressure issues; finish is a fingerprint magnet and the shell+cable combo is heavy, comfortable for average ears but failing the “tiny ears” test in stock form. Accessory spread is excellent at the price, with multiple tip sets and spare O-rings/foams rounding out a thoughtful package.
Sonically, this is textbook planar bass: clean sub-bass rumble with punchy, textured mid-bass that doesn’t bleed. The midrange stays clear and unmasked, presenting busy mixes with ease, while vocal presence shifts with nozzle choice (short nozzles push fundamentals slightly forward). Treble is where the nozzles matter most: short red = relaxed and smooth; short black = balanced sparkle; titanium/gold = vivid, edging toward “hot” for treble-sensitive listeners. Technical chops impress—crisp microdetail from the PZT without harshness, precise imaging, strong separation, and a notably 3D soundstage. It’s also very easy to drive, playing happily from modest sources.
Think of ET142 as a three-in-one planar: titanium delivers a bright, energetic V-shape (S12/“classic planar” territory), short black dials it to a balanced, less aggressive profile (S12 Pro/2024 vibe), and short red shifts into the modern warm planar lane (akin to S15/S08). Compared with other nozzle-swap sets (e.g., Timeless 2), ET142 offers a wider tuning range up top, trading fine micro-timbre tweaks for genuinely distinct signatures. Caveats: none of the nozzles are truly neutral and the low end stays boosted, so lean-bass seekers should look elsewhere; the weight may be a deal-breaker for small ears. For anyone wanting a versatile planar that can swing from sparkly and fun to warm and relaxing with a quick nozzle swap, this earns a confident “you should buy this” recommendation on value and flexibility alone.

Youtube Video Summary
SIMGOT ET142 comes across as a sleek, chrome-heavy hybrid with a planar + PZT setup, dressed in CNC’d stainless shells and a surprisingly thick premium cable, plus a magnetic case and swappable 4.4/3.5 plug. Two tuning nozzles are included; differences are subtle, but the gold nozzles give a warmer, more relaxed balance versus the blued “airier” set. At a listed ~$220, the build and accessories feel upscale, though that cable is borderline overkill for an IEM.
On power, the ET142’s 14 Ω load behaves better with a more linear solid-state source (e.g., JDS Labs Element) than with tubes; an impedance adapter can tame noise. The tuning reads smooth, non-aggressive, with bass present but not the star; sub-bass “slam” isn’t the focus, yet vocals and staging are clean and pleasing. Treble with the gold nozzles stays polite, while the blued set adds some sparkle without turning harsh.
The special sauce is the imaging: sound feels “inside” and slightly behind the head, creating a quirky but engaging sense of placement that should be excellent for gaming. Overall it fits neatly among planar hybrids at this price—refined, smooth, and easy to enjoy rather than a fireworks show—earning a straightforward recommendation, especially for SIMGOT fans who value comfort, build, and that distinctive spatial presentation over brute-force bass.

Youtube Video Summary
Build & accessories: ET142 arrives with an all-metal chassis, a tidy two-pin cable with interchangeable termination, and swappable nozzles (blue default vs. gold). The blue nozzle proves smoother, as the gold adds extra 2–3 kHz energy that can edge into shout. Ergonomics are compact, vented, and well-finished, though not as feather-light as some resin competitors.
Tuning & technicals: The hybrid architecture (planar plus bone-conduction) projects an expansive, airy stage with clean separation and layering. However, that upper-mid peak can make gunfire and busy mixes feel a bit spicy, leading to a “deer-in-headlights” sensation during chaotic moments. Tonally it’s clear and detailed, but the extra air sometimes pushes nearfield cues slightly forward in the stage instead of delivering immediate urgency.
Gaming performance: Imaging and verticality are solid and footstep cues are intelligible, placing ET142 in a B+ to B range for competitive play. Against a warmer rival with stronger low-end presence, ET142 is less fatiguing than the gold-nozzle setup but still brighter than ideal for Apex/Valorant chaos; the rival’s bass weighting keeps gunfire tamed and localization snappier. Overall, ET142 is good for gaming with strong separation and stage, best for players who value clarity and air over maximum urgency.

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 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.
