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.

Letshuoer S12 Ultra reviewed by Jays Audio
2025-10-09Youtube 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.

Simgot ET142 reviewed by Z-Reviews
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.

2025-10-05Youtube 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.
