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.

Average Technical & Tuning Grades

Average Tunign Grade

C-
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

C-
  • Textural information blurs together, making the stage feel pinched and gray. Instrument edges blur together frequently.
Bass D
It hints at bass presence but never quite delivers satisfying punch. Percussion lacks a satisfying weight.
Mids D
The region feels unstable, alternating between honky resonance and missing information. You'll hear odd resonances across the mids.
Treble D
Treble balance wavers, creating a mix of recessed detail and harsh flashes. Highs feel restless and unfocused.
Dynamics D
Volume shifts feel constrained, so build-ups plateau before releasing. Build-ups plateau before resolving.
Details D
Textural clues dull down, robbing strings and vocals of their natural grit. You hear outlines rather than textures.
Imaging D
Panning effects blur at the edges, making movement sound smeared. Fast panning effects smear noticeably.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

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.
