Noble Audio Onyx vs Simgot EW300

Noble Audio Onyx

Across Headfonia and Bloom’s approved coverage, the Onyx comes through as a premium, neutral-warm quadbrid that majors on polish, immersion, and textured low-end power rather than exaggerated V-shape theatrics. The bass is repeatedly described as strong and controlled, the mids clear and full, and the stage spacious enough to give flagship material a convincing sense of scale. The Onyx is also framed as an endgame-style listen with upscale build and presentation. Its compromises are predictable for the class: price is steep, and its character leans more toward refined fullness and immersive richness than aggressive excitement.

Simgot EW300

The Simgot EW300 is a roughly $70 tribrid: a 10mm ceramic composite dynamic driver, a 6mm planar and a piezoelectric ceramic tweeter inside a CNC machined metal shell, with two swappable nozzles (silver steel with a red O-ring, gold copper with a purple one). Reviewers agree on three things. Sub-bass reaches deep with real rumble and stays out of the midrange, the metal shell is light and comfortable and needs no amplifier at 28 ohms, and detail retrieval, separation and imaging land above what the price normally buys, which is why several reviewers name it a gaming pick. Almost everything above 1 kHz is contested. One camp hears a warm, slightly dark set whose treble lacks brilliance. Another hears a V-shaped, upper treble boosted set that turns sibilant or fatiguing on female vocals. The midrange splits the same way, lush and full against scooped, thin and clinical, and the nozzles are called anything from subtler than a tip swap to a drastic change. Two reviewers measured channel imbalance on their own units, one of them alongside a visibly misaligned internal component.
