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.

Not for bassheads, but one of the best planars I've ever heard. Jaytiss Youtube Channel

Clean, balanced, with slight air boost in the treble. Bass sounds like a DD with great texture. Cheaper better tuned P5+2. Not as smooth as Timeless 2 with more dynamic contrast with a slight sizzle from the treble boost. Good value for a planar. Jays Audio Youtube Channel

One of the best planar IEMs out there. The treble is smoother and easier on the ears than most planars. Balanced sound with clean bass, smooth mids, and detailed treble. Great clarity, wide soundstage, and natural timbre for a planar. Bass might be a bit light, and treble can be a little forward for some.Gizaudio Axel original ranking

A little bit spicy in the treble (like the other planars). Relaxed upper mid-range. Warmer tuning than S12. It's a decent IEMSuper* Review original ranking
