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 Jays Audio Youtube Channel

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
B+- Flawed execution of tonal character. Noticeable peaks/dips affect timbre and coherence. May suit specific genres but lacks refinement.
Average Technical Grade
A-- Above average technicalities. Handles separation and detail adequately in simpler tracks, but complex passages remain challenging. Soundstage is modestly sized with acceptable imaging.
