TOTL imaging chops/layering. Tons of micro-details. Bass texture and impact second probably only to the Z1R. Wide and 3D staging. AGGRESSIVE, and get fatiguing when cranked up/long-listening sessions.

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

Audionotions 8.5 Reviewer Score
Very engaging. I usually prefer something more balanced and neutral, but this IEM has some special sauce. Very well-tuned from bass to treble - with a little bit of spice on top. Great tonality and amazing techs. Imaging is quite phenomenal, separation is great. Very detailed. If you have 700 to spend on IEMs, buy these on the used market and never look back. Warning - treble can be slightly hot. Also, timbre might sound just a tad artificial. Loaner

Great bass and sheer detail, at the cost of wonky treble and not so accurate imaging queues. I find it work the best with eletronic music or modern metal. Still a solid contender to this date at a very good price in the used market.

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.
