SIMGOT EG280 VS Letshuoer S12 Ultra

Youtube Video Summary

Hybrid gaming set built around a 10 mm dynamic driver and a 6 mm planar, plus a USB-C DSP dongle and a 1.7 m cable. Stock tuning follows a Harman-style balance with a modest bass shelf and a slightly brighter upper range, which favors imaging, FX clarity, and footsteps in shooters. Technical performance is solid for the class: the planar adds resolve without obvious planar timbre, making the set feel more like a clean hybrid than a pure DD.

The idea here is presets: SIMGOT provides app control and WalkPlay hosts multiple music and game modes as well as community uploads, so the EG280 is best treated as a flexible DSP platform. For music, a gentle low-Q tilt (bass up a few dB, treble down a touch) yields a more fun, less fatiguing listen; stage is serviceable rather than wide, while detail retrieval and positional cues remain a strength. Overall, it is a capable, EQ-friendly gaming hybrid that can double for music with minimal EQ, but out-of-box brightness means it benefits from presets to shine.

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 EG280 comes tuned as a balanced all-rounder with a touch of upper-mids/vocal emphasis. The bass is thumpy, full, and clean—adding weight without bleed or warmth bloat—while a slightly forward midrange brings clarity and presence to voices. A purposeful 4–8 kHz dip keeps the set from turning shouty, and the treble—handled by planars—stays natural without the zingy “planar timbre.” Extension is adequate to mildly airy, revealing small details without sounding artificial.

There is a caveat: a 13 kHz peak can pop up on brighter K-/J-Pop or lean mixes, so mid listening levels (~70–75 dB) are the sweet spot. Technically it sits above EW300 but slightly below EA500 LM/EM6L, trading max microdetail for a more natural, less bright tonality. Genre fit is broad—from pop and indie to electronic—so long as volume isn’t cranked. Tip pairing favors smoother or bass-adding tips (e.g., Final E, Softears Ultra Clear) over anything that pushes treble further.

Imaging is a standout for the price, giving gunshots and footsteps extra pop without harshness, which makes the EG280 surprisingly solid for gaming. The lightweight build and low-microphonic cable boost comfort for long sessions. Overall, think safe, balanced, and versatile rather than showy “special sauce”: a set that’s easy to live with, competitive in value, and a smarter pick for mixed music + gaming than brighter, sharper peers—just mind that upper-treble spike on hot masters.

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 Simgot EG280 is a compact hybrid gaming IEM priced around 79 dollars, packaged with multiple narrow and wide bore tips, a pocketable zipper case and a 3.5 millimeter cable with inline microphone. The resin shell with metal faceplate feels sturdy yet light, the small earpieces and integrated wing provide a secure fit, and passive isolation is above average, which helps the presentation feel more immersive in noisy environments.

Tonality is best described as a balanced allrounder. Bass is forward and full with satisfying mid bass punch and a smooth gliding character that avoids muddiness, while mids are slightly warm with excellent vocal clarity so voices sit clearly in the mix and instruments stay natural and full bodied. Treble is clean and boosted enough to pull out micro details and add sparkle, but on some tracks it can come across a little sharp or too forward, so treble sensitive listeners may want to take advantage of EQ.

Technical performance is described as solid, with notably solid imaging and overall resolution that sits roughly midway between sets like the Moondrop 22 and Truth Ear Nova on the usual technical scale. The included USB dongle is more powerful than the typical USB C cable on competitors, integrates with the Simgot control app for presets, a ten band parametric EQ and microphone gain control, and can even be used with other IEMs for extra versatility. Versus the Moondrop Rays, overall resolution and sound quality are quite similar, so the EG280 feels redundant for existing Rays owners, but for new buyers who plan to tame the upper treble with EQ, it offers a comparable sound at a lower price with a very flexible dongle based feature set.

Youtube Video Summary

The SIMGOT EG280 makes a strong first impression for budget gaming with a curve reminiscent of Harman 2019: footsteps (both low and upper registers) and gunfire pop through cleanly, giving deathmatch sessions a snappy, almost B+-tier feel. However, once the action shifts to coordinated 5v5 play, the mix starts to blur—layering behind walls turns into a “mashed potato” effect, and horizontal cues lack the tactile edge that marks exact peeks and thresholds.

In Valorant and Apex, the same pattern holds: respectable general imaging, but depth perception and separation take noticeable hits when the battlefield gets chaotic. Smokes, thermites, ultimates, and sustained gunfire mask lighter cues—leading to those “where did this guy come from?” moments—and vertical readouts feel approximate rather than pinpoint. Overall placement sits around a B- for both titles: a pleasant, airy presentation that’s easy to enjoy in lighter modes, but not the clearest tool for high-level competitive awareness when the screen fills with abilities and crossfire.

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.
