Simgot SuperMix 5

Name: Simgot SuperMix 5
Brand: Simgot

Simgot's bone-conduction gamble — a calmer, fuller-voiced, big-staged SuperMix that half the field calls a mature all-rounder and the other half calls an overpriced sidegrade with a coil that twangs.

The short version

What to know.

A $220 five-driver hybrid IEM (8 mm DLC dynamic driver, two balanced armatures, a micro-planar tweeter and a 10 mm bone-conduction driver) voiced as a smoothed-out Harman — neutral with a modest bass lift, a restrained ear gain and a relaxed treble. Reviewers agree on what it is: a calm, coherent, vocal-centred all-rounder with a controlled, textured, quality-over-quantity bass, a wide-for-the-price stage that is unusually tall and deep, and imaging good enough for gaming; the 21 measurement rigs back the tuning description to within a decibel, and show it running 2–5 dB under both the Harman target and the SuperMix 4 across the bass and the treble. Almost everything else is argued: whether the midrange is full and natural or clean but lean; whether the treble is the right kind of safe or simply dark and cold; whether it resolves as much as a $220 set should or less than the $150 SM4; whether its dynamics are tactile or flat; whether the big shell and long nozzle are comfortable or a deal-breaker; whether the bone-conduction coil is a clever tactile bonus or a springy driver that twangs, hums and buzzes; and, above all, whether any of it is worth $70 more than the SuperMix 4. The recurring practical advice is consistent across camps: change the stock tips, don't jam it in deep, and give it volume — the bone-conduction driver does little until it has firm contact and level.

About this product

The Simgot SuperMix 5 (SM5) — the second SuperMix, but a different design rather than a revision: five drivers (an 8 mm DLC dynamic driver, two balanced armatures, a micro-planar tweeter and a 10 mm custom-coil bone-conduction driver that works from about 200 Hz to 7 kHz) behind an RC four-way crossover, in a larger 3D-printed resin shell with a satin aluminium faceplate and a long metal nozzle, 19 Ω / 120 dB. It replaces the SuperMix 4's piezoelectric tweeter with the bone-conduction driver and adds a second BA, and it is voiced noticeably calmer: measurably less bass, less upper-mid presence and less treble than the ~$150 SuperMix 4, which stays on sale beside it. Because the bone-conduction driver only works through shell-to-ear contact, tips and insertion depth change this set more than most — nearly every reviewer swapped the stock tips.

The Simgot SuperMix 5 is the follow-up to one of the most recommended sub-$200 IEMs of 2024, and it is not the sequel people expected. Where the SuperMix 4 was a bright, forward, four-driver Harman set that punched far above $150, the SM5 keeps the 'quadbrid' idea but swaps the piezoelectric tweeter for a 10 mm bone-conduction driver, adds a second balanced armature, grows the shell, and raises the price to $220. The tuning moves with it: still Harman-referenced, but with the bass shelf, the ear gain and the treble all pulled back a few decibels.

Nine months in, the reviews cluster into two clear readings. One hears a grown-up Simgot — natural, full-voiced vocals, a tactile low end you feel as much as hear, a tall and deep stage, and a treble that finally doesn't bite. The other hears a set that gave up the SM4's energy and resolution for a gimmick driver that pings when you chew, in a chunky shell, at a price where the Kiwi Ears, ZiiGaat and AFUL competition is fierce. Both camps are well represented, so this is a map of where they agree and where they don't.

A good fit for

Listeners who found the SuperMix 4 (or Simgot's house sound) too bright or thin and want the same brand's calmer, fuller-voiced take
Vocal-first, long-session listeners who prize a smooth treble and a tall, deep stage over sparkle
Anyone curious about bone conduction who wants the most coherent budget implementation reviewers have heard so far — and is willing to tip-roll to get it
Precision-style FPS players (imaging and separation are consistent praise)

Think twice if

You own or love the SuperMix 4 and expect 'the same but better' — it is a different, calmer set, not an upgrade in energy or resolution
You want big slam or an airy, sparkly, resolving top end at this price
You have small ears, side-sleep in IEMs, or already dislike long nozzles and chunky shells
Handling noise bothers you — the bone-conduction coil pings when the shell is touched or the jaw moves, and a few owners report a hum at rest
You are price-sensitive: many reviewers who like it still say to wait for a sale

8 / 12topics divide opinion

1 Strong agreement3 Mostly agree8 Divided opinions

Common ground5

A smoothed, warm-leaning Harman tuning — neutral with a modest sub-bass lift, restrained ear gain and a relaxed treble; every rig and reviewer describes the same shape
Controlled, fast, textured bass that is felt as much as heard — quality over quantity, not for bassheads
A stage that is unusually tall and deep for the price, and imaging good enough for competitive gaming
The five drivers blend coherently; timbre is more natural and less bright than the SuperMix 4's
Easy to drive and far less source-fussy than the SM4, but the stock tips and a deep insertion mute the bone-conduction effect — tip-rolling is near-universal

Points of contention8

Midrange body: full, natural and tactile vs clean but lean, with thin baritones and a cold streak
Treble: smooth and fatigue-free vs too safe, rolled-off and airless — and a small camp that still hears edge with the stock tips
Detail: resolving for $220 vs only average, with the cheaper SM4 named as the more technical set
Dynamics: tactile and lively vs controlled to the point of flat
Fit: a comfortable pseudo-custom shell vs a bulky body and long nozzle that some cannot live with
The bone-conduction coil: a clever tactile bonus vs a springy driver that twangs, hums and buzzes
Whether a consistent seal (and so isolation) is easy or elusive
Value: a mature step forward vs an overpriced sidegrade — wait for a sale

The one thing nobody disputes: a smoothed, warm-leaning Harman — neutral with a modest sub-bass lift, a restrained ear gain and a relaxed top — described variously as 'neutral with bass boost', 'mild U', 'warm-neutral' and 'JM-1-leaning'. The argument is only about whether that reads as mature or as safe-to-a-fault.

“The Simgot SuperMix 5 has what I’d call a neutral sound color with a vibrant upper-mid emphasis, as well as a sublevel boost”
Mobileaudiophile (Chris Love)

“basically an adjusted Harman that aims to be a safe all-rounder”
IEMRanking (summarising Jays Audio)

“the SuperMix 5 sound is smooth, relaxed, musical, warm, neutral, tends to be dark, and much more coherent”
u/zipx1, r/IemReviews

Measured

21 IEC-711-class rigs agree to within a decibel up to 4 kHz: a +6.5 dB sub-bass shelf over the lower mids, an ear-gain peak of +8.3 dB at 3 kHz, and a treble that falls to +3 dB by 6 kHz and below the mids by 10 kHz. Against Harman IE 2019 it sits under the target everywhere — about −2.5 dB at 20 Hz, −2.5 to −3.5 dB from 2 to 5 kHz and −5 dB at 6 kHz. Against the SuperMix 4 on twelve shared rigs it has 4.4 dB less at 20 Hz, ~3 dB less at 2–2.5 kHz, 2–3 dB less from 5 to 8 kHz and 6–9 dB less above 12 kHz.

Broadly praised for quality — fast, tight, textured, and with a tactile 'felt' quality most credit to the bone-conduction driver — and broadly agreed to be modest in quantity: controlled, sub-bass-led, not for bassheads. Two fringes disagree on how much there is: a bassy-sounding minority (THL calls it nearly basshead) and a light-sounding one that finds the mid-bass vanilla and reaches for EQ. Most of the spread tracks fit — deep insertion and the stock tips both mute the bone-conduction contribution.

“Punchiness is the strongest impression the low end makes, with kick drums and bass hits landing with fast, physical precision that feels decisive and contained.”
Headfonics (Kurt)

“this is a quality over quantity style of bass which is not going to impress the bass bois amongst us”
Mobileaudiophile (Chris Love)

“this lower end is easily the most complete lower end I have heard in an IEM under $500”
The Headphone List (Suman Sourav Meher)

“It’s a very technical bass, to be fair, but it lacks characters or souls.”
Head-Fi (vandung2510)

Measured

Shelf of +6.5 dB at 20 Hz and +2.7 dB at 100 Hz over the lower mids on the 21-rig mean (sd 1.2 and 0.7) — about 2–2.5 dB under Harman IE 2019 and 4.4 dB (20 Hz) / 2.4 dB (100 Hz) under the SuperMix 4 on the same rigs. A shallow seat adds ~1.3 dB at 20 Hz and a deep one takes ~0.5 dB away; foam tips change nothing below 1 kHz; a 30 Ω source adds +2.8 dB at 20 Hz (the SM4 gained +10 dB on the same test). Two retail units match within 0.5 dB.

vs. listeners — The graphs put it firmly in the 'restrained' camp — there is simply less bass here than in the SM4 or the target. The 'nearly basshead' readings describe the bone-conduction driver's tactile contribution, which a coupler cannot see and which depends entirely on shell contact; the 'too light' readings mostly come from listeners using the stock tips or a deep insertion, where that contribution is weakest.

Sources split three ways: the majority hear a controlled, natural, fatigue-free treble that finally drops Simgot's edge and is the right call for long sessions; a large minority hear the same tuning as too safe — rolled-off, cold, short on air and sparkle, and a step down in perceived resolution; and a small third group still find the lower treble edgy or fatiguing, almost always with the stock tips. Insertion depth swings the 6–9 kHz region by several decibels, which is most of that third camp.

Measured

From 5 to 8 kHz the 21-rig mean runs 3–5 dB under Harman IE 2019 (+5.7 dB at 5 kHz, +3.2 at 6 kHz, +2.3 at 8 kHz over the mids) and 2–3 dB under the SuperMix 4; 10 kHz is at −1 dB and 15 kHz at −8. A shallow seat lifts 6 kHz by +4.6 dB and 7 kHz by +2.4 on Super* Review's rig (+2.2/+2.6 on ATechReviews'), a deep seat cuts 7–8 kHz by ~3 dB; foam tips take another 1 dB from 4–6 kHz and 2.4 dB from 10–12 kHz.

vs. listeners — The graphs support 'relaxed', not 'bright': the treble is under target from 5 kHz up on every rig. The 'edgy' minority is not imagining it, though — a shallow seat on the long nozzle is the brightest configuration at 5–7 kHz by 2–5 dB, and the stock tips are the ones reviewers say seat shallow. The 'cold / no air' camp and the 'smooth' camp are reading the same −3 to −5 dB the same way and disagreeing only about whether it is a virtue.

What to keep in mind 8

A read of where the reviews land as of mid-September 2026, nine months after launch. Most written and video verdicts date from December 2025 to February 2026; the owner reviews and a second wave of long-term write-ups run through the summer, and they are more divided than the launch coverage was.
The owner ratings are a small, split sample: Amazon's 3.9 comes from 16 ratings that are almost all either five stars or three-and-under, Linsoul's own store shows 4.6 from 7, and Head-Fi's 20 showcase reviews average 4.3 — but the great majority of those were review units from the maker or its distributor.
This set changes more with fit than most. The bone-conduction driver only works through firm shell-to-ear contact, so the stock tips, a deep insertion or small ears can leave you with a thinner, brighter, less tactile earphone than the reviewers who tip-rolled describe. If it sounds flat or light, try larger tips and a shallower seat before judging it — and know that a shallow seat also lifts the 6 kHz region.
Which midrange and treble camp you join tracks what you play: vocal, jazz and acoustic listeners are the ones who hear thin baritones and a cold top; rock, electronic and pop listeners hear warmth, ease and body.
The coil that drives the bone-conduction effect is mechanically live: touching the shell, chewing or talking produces a springy ping, and a few owners and two reviewers report a faint hum or buzz at rest. Two measured retail units match closely, so this is a characteristic to audition for, not a lottery.
If you own the SuperMix 4, expect a different earphone rather than a step up: the graphs show 2–4 dB less bass and treble and a tamer upper midrange, and the reviewers who preferred the SM4 did so for its energy and resolution, not for a flaw in the SM5.
It reaches volume from anything, and unlike the SM4 it barely changes through a high-impedance output — but nearly everyone says it only comes alive at moderate-to-high listening levels, so quiet listeners may never hear what the fans hear.
The field keeps moving: the Kiwi Ears Astral and Quintet, ZiiGaat Odyssey 2, AFUL Performer 5+2, Dunu DN-142, CrinEar Daybreak, Tanchjim Fola and 7Hz Divine are what reviewers cross-shop it against, and several think the $150 SuperMix 4 or a sale price is where the SM5 makes sense.
