Simgot Supermix 4 VS Hidizs mk12 x Ducbloke

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.

The Hidizs MK12 × DucBloke is a special-tuned edition built on the MK12 “Turris” platform, which uses a single 12 mm dynamic driver with a 91% magnesium diaphragm and a 1.5 T magnet system inside a CNC-milled metal shell. The base MK12 includes three swappable pneumatic filters and retails around $199 (often $179 on sale), with Hidizs officially confirming the DucBloke collaboration and demos at CanJam SoCal 2025.

Tonal balance with the MK12 platform is broadly warm U-shaped and can be shifted via the filters: Silver lifts treble, Rose Gold/Gold aims for a balanced profile, and Red boosts low frequencies while relaxing the upper mids—behavior documented across launch materials and reviews. This aligns with independent measurements/impressions noting the red filter’s fuller bass and the silver filter’s added upper-energy, giving the DucBloke edition a clear path toward a bass-weighted yet smooth top end.

Technical performance is competitive in the sub-$200 class: reviewers consistently describe a spacious soundstage, convincing imaging, and strong dynamics for a single-DD, while ultimate micro-detail and treble air are good rather than class-leading. With the right filter and tips, the set offers solid clarity without harshness and bass impact that should satisfy listeners seeking weight and physicality. Overall, the value proposition is strong at its street price, especially if the DucBloke tuning prioritizes the red-filter’s engaging low-end.
