The SIMGOT EG280 is a budget-class, hybrid gaming IEM that pairs a 10 mm dynamic driver with a 6 mm planar unit per side (rated at 32 Ω, 119 dB/Vrms), a configuration positioned to blend bass weight with fast mid/treble transients. Packaging is unusually comprehensive at this price: a long ~1.7 m 2-pin cable with inline mic plus a bundled USB-C DAC that works with the SIMGOT Control app for preset EQ and game profiles, making it plug-and-play across phones and laptops. Street pricing has launched around ¥299 / ~$42–45, putting it squarely in value territory for an entry gaming set. .

On tonality and performance, the EG280 is pitched for positional accuracy and clarity—marketing materials emphasize “seamless frequency transition” and game-oriented EQ options—so expectations should lean toward a mildly U-shaped balance with clean mids and crisp upper registers rather than basshead emphasis. Early community impressions and graphs likewise frame it as a clear, energetic listen with solid imaging for competitive titles, while the included DAC/app path offers useful tailoring if treble sheen or bass quantity needs trimming for long sessions. At the price, technicalities (detail retrieval, imaging precision) are respectable; staging depth and macrodynamics are more modest, which is typical in this cost bracket. .

B Tech

Fosi Audio’s IM4 is an unusual entry-level IEM that uses an open-back shell and a single 10 mm beryllium-coated dynamic driver, aiming for a more natural presentation than typical sealed designs. The open back expands perceived space but also leaks sound and offers little isolation, making it better for quiet environments than commuting . Launch pricing sits at $99, with CNC-machined aluminum shells and a dual-magnet N52 motor backing the diaphragm for control and efficiency .

Sonically, the IM4 targets a balanced/neutral tonality with moderate bass lift and smooth upper mids, yielding an easygoing listen rather than a V-shaped “wow” effect. Stage width is a relative strength for the price—helped by the open-back architecture—while imaging is clean if not class-leading; macrodynamics and microdetail are competent but won’t dethrone closed rivals known for slam. Build and fit are light and ergonomic, and the package includes interchangeable nozzles (aluminum vs. brass) that subtly adjust brightness/sibilance, offering a bit of tuning flexibility without EQ .

Gaming-focused hybrid with DSP presets and a long USB-C cable. Resolving with sharp imaging, but the stock tuning is bright and benefits from EQ for music. Capable hybrid drivers with good resolve, plus onboard DSP and WalkPlay presets for game-specific tuning. Stock tuning is bright for music and the soundstage is only average without presets.
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.

A- Tech
All-rounder with pinpoint imaging and slight uppermids/vocal emphasis. Basically a more technical EW300 with better vocal clarity and extension. Solid for gaming like EM6L, and would be my pick since it's more natural/less bright vs EM6L.
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.

SIMGOT EG280 reviewed by Fresh Reviews

Fresh Reviews 5.5* * The score of this reviewer influences only the Gaming Score
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.

Nice impression, very audiophile tuned.
Youtube Video Summary

Fosi Audio IM4 brings a beryllium-coated single DD in a compact shell with thoughtful venting that behaves almost open-back for comfort during long sessions. Build is surprisingly premium for ~$100: a small, well-finished nozzle that grips tips, a light but durable cable with color-coded channels and a working chin slider, a tidy case, and tuning nozzles (black/gold) plus multiple tips. It’s the kind of fit and finish usually saved for pricier sets.

Tonally, this is an engaging, warm-rich tuning with elevated sub-bass, good texture, and plenty of detail—not a neutral reference. There’s energy in the 2–4 kHz region and a bit of 5–6 kHz bite that can read as “cat-ear” presence, trading strict smoothness for extra soundstage perception and clarity. Versus the many neutral options at this price, IM4 feels more characterful and fun; think closer to sets that use a staged upper-mid/treble contour than to flat targets. Filters/foams or a touch of EQ can gently tame peaks while keeping the lively character.

On the scoreboard: bass 7/10 (clean shelf and punch), mids a touch recessed versus a neutral target, treble lively with agreeable detail, and stage/detail notably good for the class. Overall, a well-built, fun, and slightly audiophile-tuned single-DD that will appeal to listeners who value texture and excitement over strict neutrality—plus rare build quality and extras at this price make it a solid value.

Youtube Video Summary

Quirky name aside, the Fosi Audio IM4 brings a 10 mm beryllium-coated single dynamic driver with a tuning that reads more cohesive, clean, and neutral than bass-bomber. Music floats with a great soundstage and a velvety midrange, giving smooth-jazz and vintage recordings that “swirling around the head” vibe without getting muddy. Hints suggest a price under $100, which would make this one of the stronger performers in the budget bracket, especially given the unexpectedly premium build.

The shells feel like they were machined from the same stuff as Fosi’s amps—weighty, thick, nearly indestructible metal—with a solid 3.5 mm cable (no 4.4 option noted). Accessories are unusually thoughtful: two tuning nozzles (black = lightly damped; brass = no damping) and three styles of tips. Swap to the brass nozzle and treble detail jumps while bass eases off, which can turn the top end a touch spicy for some; stick with the damped setup for a smoother, “just be good” balance. Add a decent case and, if the rumored price sticks, it’s a high-confidence recommendation in the sub-$100 class.
