A slightly more V-shaped version of the Truthear Nova. A bit more bass, a bit more treble. Not as vocal focused. Some of the best technical performance at $150. Good accessories. Shells are more compact than the Nova.

Endgame Harman, one of the smoothest IEMs I've heard with Tangzu Sancai tips (regular). Some units might be hotter in the treble/pzt timbre

The Simgot Supermix 4 packs a quadbrid driver configuration (1DD+1BA+1 Planar+1 PZT) into a comfortable resin shell. Its sound follows a U-shaped signature aligned with the Harman IE 2019 target, emphasizing sub-bass rumble and crisp upper-midrange clarity while keeping lower mids slightly recessed. The bass is deep and textured, though mid-bass punch can feel soft, and vocals sometimes edge into shoutiness at higher volumes.

Treble delivery is a standout, with the planar and PZT drivers offering snappy articulation and air without harsh sibilance. Technical performance is strong for the price, featuring a wide soundstage and precise imaging that excels in gaming scenarios. However, low impedance makes it source-sensitive, and accessories feel minimal with only one set of tips included.

While not class-leading in resolution, the Supermix 4 delivers cohesive tonality across its diverse drivers, making it a versatile choice for bass-forward genres and competitive gaming. Its slight warmth and holographic staging compensate for minor midrange thinning, offering solid value despite fierce competition.

Simgot Supermix 4 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

B+
  • It sounds pleasant overall, with some uneven spots that hint at room for refinement. Vocals remain pleasant despite the imperfections.

Average Technical Grade

A-
  • It manages detail and layering well enough, even if the stage feels only moderately sized. You get a clear sense of left and right, if not depth.
Bass A+
You hear powerful yet disciplined low-end slam that extends effortlessly. It marries sub-bass depth with great texture.
Mids A-
Expect lifelike vocals and instruments with impressive nuance and realism. You can easily follow harmonies and backups.
Treble B+
The top end is engaging and airy, yet never overbearing. Brass and strings feel energetic.
Dynamics B
You get confident dynamics that track both macro swings and rhythmic drive. There's life in every crescendo.
Soundstage B
Lateral spread stretches comfortably while front/back cues start to feel convincing. You can trace front-to-back movement.
Gaming A-
Good fundamental spatial awareness for most gaming scenarios. Handles basic positioning well but may lack nuance in complex situations.

Average Technical & Tuning Grades

Average Tunign Grade

D
  • It struggles with balance, producing a lumpy response that rarely sounds coherent. Genre hopping highlights glaring inconsistencies.

Average Technical Grade

E+
  • A foggy, one-dimensional presentation wipes out layering and obscures the finer points of a mix. Spatial cues barely register at all.
Mids C-
It delivers a workable midrange that could benefit from smoother transitions. Timbre isn't quite convincing yet.
Treble E+
Treble leans dark, softening cymbals and trimming extension. Brightness is replaced with a murky haze.
Dynamics E-
Dynamics barely flicker, leaving energetic sections strangely subdued. There's no punch to latch onto.
Soundstage C+
You start to perceive distinct rows of players even if the ceiling still feels low. Layering is present but still modest.
Gaming E+
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
