Foam helps tame uppermids/treble. Amazing detail for price and new benchmark below $100. Better tuned "softer" Dusk with slighlty less accurate imaging. Note-weight can be light.

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

Unique neutral-bright sound signature, but overall feels a little unengaging. Clean, clear vocals with decent detail. Bass quality and impact, mids can feel lean, and treble can get a bit bright.

Audionotions 5.5 Reviewer Score
Like the B2 but a step down in resolution and separation - very well-tuned - could use a tad more bass quantity and tighter bass (it sounds a bit fuzzy and loose - I guess they aren't using a very good DD), and better treble (this problem can be fixed by using wide bore tips). Great value for $79 - no comfort, fit, or QC issues like the B2 but in exchange. Previously Owned

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.
