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.

The Kiwi Ears Airoso offers a warm, smooth sound signature characterized by a full-bodied bass with satisfying sub-bass rumble and quick decay, though mid-bass impact remains reserved. Its midrange shines with a natural and organic presentation, particularly excelling with female vocals, though some male vocals lack weight. Treble is relaxed and non-fatiguing, providing decent air but lacking sparkle and ultimate detail retrieval.
Comfort is a mixed bag; the lightweight resin shells with CNC aluminum/titanium faceplates are praised by some, but others report significant fit challenges due to the shell shape and nozzle design, requiring tip rolling beyond the included selection. The stock cable is widely criticized as basic and low-quality for the price point, though the detachable 2-pin design allows for upgrades. Soundstage is reasonably spacious but not particularly expansive, with imaging being competent rather than exceptional.
