The SuperMix 5 is a five-driver hybrid IEM. The standout feature is a bone-conduction driver operating across a wide frequency range, adding a more physical, tactile sensation than typical IEMs. It launches at 219 USD/€185 (ex.tax).
As mentioned, there are 5 drivers. There’s an 8 mm dynamic driver for the bass, two balanced armatures for the midrange, and a micro planar magnetic driver for the treble. That configuration isn’t particularly unique, but the addition of a custom 10 mm coil bone-conduction driver is more unusual. It’s not the first of its kind — I’ve tested the Kiwi Ears Etude, which uses a similar vibration driver, though for different frequencies.
The vibration driver in the SuperMix 5 works from about 200 Hz to 7 kHz — a surprisingly broad range that covers upper bass, the entire midrange, and even part of the lower treble. Bone conduction isn’t just for adding a “rumble”; it’s a known way of reproducing sound on its own. In the SuperMix 5, the bone-conduction driver isn’t only there for physical impact — it’s designed to add extra detail and texture, and it definitely contributes something noticeable to the overall listening experience.
The SuperMix also uses a four-way crossover — presumably one section for each driver type — along with four separate acoustic tubes. In addition, it employs what the company calls a “multi-path acoustic damping tuning system,” which appears to be a set of internal physical structures designed to damp and fine-tune the frequencies.

BUILD AND COMFORT
The SuperMix 5 shells are made from translucent resin — a cool look, though the effect is only visible when you hold them up to the light. The faceplate is CNC-machined metal. The shells are slightly on the larger side but sit comfortably in the ear, and if you tap them with your finger you can feel the vibration driver give a springy feedback.
The cable looks and feels premium, made from silver-plated OCC Litz. It’s slightly thicker than I’d prefer, but not a major issue. It uses 0.78 mm 2-pin connectors and comes with interchangeable 3.5 mm and 4.4 mm termination plugs.
The SuperMix 5 comes with a sleek black faux-leather storage case with a magnetic closure, similar to the case many premium Simgot IEMs have come with before.
Two types of silicone tips are included, each in three sizes, though I prefer to use my own third-party tips for comfort and convenience.
VIBRATION DRIVERS
Vibration drivers for the midrange and bass in IEMs are still quite rare and relatively new, but they’re more commonly used for the treble.
Although they share similarities with standard bone-conduction technology, normal IEMs don’t make direct contact with the bone, so all vibrations have to travel through the eartip (or the air) — which isn’t very efficient. Standard bone-conduction earphones, by contrast, sit on the head, typically directly above the ear, allowing vibrations to go straight into the skull and from there into the ear where it becomes “translated” to sound in the inner ear.
It’s difficult for me to know how much of what I’m hearing and feeling comes from the vibration driver versus the regular drivers. The idea, however, is to add an extra physical dimension to the sound — and the SuperMix 5 does feel quite tactile.

Rambling Man by Laura Marling
Vocals sound natural, and the overall presentation is well balanced. In busy passages, the SuperMix 5 keeps up, offering excellent instrument separation and effortless sound, with vocals centered in the mix.
Sunrise by Norah Jones
The bass isn’t especially powerful — it can be overwhelming on many earphones, but not here. Vocals can sometimes feel too forward on other IEMs, but the SuperMix 5 keeps them well balanced and natural.
In The Mountains by Espen Eriksen Trio
The bass isn’t overwhelming but nicely present. The piano is nuanced, neither warm nor cold, with everything sounding very well balanced.
Angel by Massive Attack
The bass drum feels very physical, likely aided by the bone-conduction driver, and it’s quite satisfying. Vocals are neutral and natural, there is good instrument separation.
Limit to Your Love by James Blake
Vocals are clear without being dry or overly crisp. The bass is meaty but not overpowering, and both vocals and percussion stand out beautifully.
Bullet in the Head by Rage Against the Machine
Full-bodied, snappy, and well-articulated, with an excellent overall delivery. The bassline and drums again have a notably physical presence.
The Tunnel by Tord Gustavsen Trio
Percussion is very snappy, with a balanced overall delivery and great instrument separation.
Rocket Man by Bob James Trio
Excellently balanced with great instrument separation, and a tactile dimension to the percussion that isn’t always present on this track.
Little Wing by Stevie Ray Vaughan
I played this track endlessly as a kid. One of the better electric guitar performances I’ve heard. The SuperMix 5 is energetic and vibrant, yet not overly warm. Percussion is snappy, with a very dynamic and articulate overall delivery.
Sonate in A Minor – E.J. de la Guerre by Sophie de Bardonnèche
Excellent, energetic delivery. The strings feel organic and tactile, with outstanding instrument separation, a large soundstage, and precise imaging.
Hurry by Mike Dillon
The vibraphone sounds more vibrant than usual, likely thanks to the bone-conduction driver.
Spontaneous Compositorius by Thomas Agergard
The saxophone has a smooth, neutral timbre. The bright percussion is crisp and clear without being overly sharp or laid-back. The bass is well balanced, present but not overpowering.
Mahler’s Symphony No 2 III by Paavo Järvi
The kettle drums have a nice body with good texture, without being excessive. Strings are slightly dark with great timbre, offering excellent separation and layering.
Maple Noise by Greene Serene
This track sounds very dynamic in a nice and tactile way.
WRAPPING IT UP
Sound Signature
The Simgot SuperMix 5 has a relatively neutral sound signature with a smooth, slightly lush touch. The midrange and bass leans warm but definitely aren’t overly warm.
Treble
The treble is clear and crisp, without getting overly sharp or harsh. I find it nicely present and neither laid-back nor dark. It’s well balanced and energetic enough to be lively.
Midrange
The midrange is very smooth yet detailed. I often find it to be a tad dark. There’s a hint of warmth, but if you are looking for a very warm and intense midrange performance, the SuperMix 5 isn’t there. It’s neutral and natural.
Bass
The bass is present but not overpowering — this isn’t a bass-heavy IEM. It sounds natural and well balanced, neutral without being as flat or thin as some studio-grade neutral headphones.
Soundstage and Imaging
The soundstage is good for an IEM, and the imaging is excellent. Instrument separation is very good, the background is dark, and the overall sense of depth is very good.
Detail, Dynamics, and Timbre
The detail level is excellent across the frequency range, especially the mids and treble.
The SuperMix 5 feels very tactile: Macrodynamics are impressive and microdynamics are also great, with excellent articulation.
In terms of timbre, I find the SuperMix 5 to feel organic, slightly laid-back, refined and smoothly pleasant — while still staying fairly neutral.

SUPERMIX 4 vs SUPERMIX 5
The Simgot SuperMix 4 was launched in mid-2024 and uses four different drivers of four types: a dynamic driver for the lows, a balanced-armature driver for the mids, and both a planar magnetic and a piezoelectric driver for the highs. Its typical price is around 150 USD.
Compared with the SuperMix 5, the SuperMix 4 is generally drier and crisper. Bass quantity is similar, but there’s more energy in the upper mids and treble. The SuperMix 5 offers better detail in the mids and highs, while the SuperMix 4 delivers better texture in the bass.

KIWI EARS ÉTUDE vsv SuperMix 5
The Kiwi Ears Étude is a tribrid with a 10 mm dynamic driver for the bass, a balanced armature for the midrange, and a dual balanced-armature tweeter for the highs. It also includes a vibration driver similar to the one in the SuperMix 5, though with a narrower frequency range. The Étude costs around 110 USD.
In terms of tuning, the Étude is warmer, darker, and fuller sounding than the relatively neutral SuperMix 5. Preference is largely a matter of taste. When it comes to technical performance, however, the SuperMix 5 is objectively better, which helps justify its higher price.

AMPLIFICATION
So far I’ve been using desktop amplifiers and DACs, but many readers will likely use the SuperMix 5 with portable sources, so I’ll test a few below.
I begin with the cheap and small Letshuoer USB dongle, DT01 Pro. It is very impressive, and I think it is a great match for the SuperMix 5. Kiwi Ears’ Allegro Pro might be a tad better. The Letshuoer DT03 also performs well. The Alpha XI1 ONIX works equally well or better.
The xDuoo Link2 Bal2 is a step up, it’s a bit more refined sounding than the previous options. The Dragonfly Cobalt is even better. Slightly more detail but a tad brighter.
Finally, the Chord Mojo is superb as (almost) always.
All in all, the Horizon sounds good with every DAC-amplifier I’ve tried, but some are better than others. The Letshuoer DT01 is certainly a budget delight, the Mojo is fantastic.
CONCLUSION
The SuperMix 5 is a remarkably well put-together and well-tuned IEM. It has a touch of warmth and a very tactile, organic character, while still staying mostly neutral with a tasteful Harman-style lift in the bass. I’m not sure what more one could reasonably expect at this price, and I can wholeheartedly recommend the SuperMix 5.
