Simgot Supermix 4 VS Kinera Celest Yaksha

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

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.

Great sonic Value, but has a few issues I'll talk of in the review.

The Kinera Celest Yaksha combines a 2DD+1BA+1 micro-planar driver setup with a four-way crossover, resulting in a coherent yet distinctly V-shaped sound. Bass emphasis leans toward the mid-bass, delivering satisfying punch and slam for genres like hip-hop and EDM, though sub-bass texture and speed feel less refined. Vocals, particularly female vocals, carry notable energy and forwardness in the upper midrange, but this can border on shoutiness with certain tracks, while male vocals occasionally take a backseat. Treble remains smooth and non-fatiguing, prioritizing listenability over sparkling extension or airiness.

Technically, the Yaksha presents a moderately wide soundstage but lacks significant depth and height, creating a more intimate headspace. Instrument separation is competent in less complex passages, but layering can struggle during busy sections, falling short of class-leading resolution. The ergonomic resin shells offer comfort for extended sessions, though achieving an optimal seal is crucial and tip-dependent. The included 6N OCC Litz cable with interchangeable 3.5mm/4.4mm plugs is a practical inclusion, though its colorful design might clash aesthetically with the shell options.

Ultimately, the Yaksha excels as a forgiving, non-critical listen best suited for dynamic, bass-forward genres where its warmth and vocal energy can shine. Its tuning sacrifices ultimate detail retrieval and sub-bass control for a consistently engaging and musical presentation. Listeners seeking a smooth, fun signature with solid build and accessories will find merit, but those prioritizing neutrality, technical precision, or deep sub-bass rumble might explore alternatives.
