Solid set, very enjoyable.
Youtube Video Summary

$50 single dynamic driver with a surprisingly premium feel: a compact, solid shell, gold nozzle, flat 2-pin connectors, and a neat white cable with a chin slider that actually stays put. The small included case is simple but well-built, and there’s a second nozzle to tweak the sound plus basic tips—nothing flashy, just clean and functional. Overall presentation looks and feels pricier than the tag suggests.

Tonally, this is a flat-neutral leaning set with impactful bass, clean mids, and extension that’s acceptable for the bracket; minor caveats include a desire for a touch more sub-bass and elevated energy around 4–5 kHz and 8 kHz. Detail and air are solid for the money, imaging is confident, and the stage feels pleasantly open, though upper-treble can edge into splashy territory. It’s not the budget slayer hyped elsewhere, but it’s a very good listen that suits a wide audience, especially those who prefer a more laid-back tuning.

Against peers: preferred over the brand’s planar Klar; the livelier Delci brings more bass sparkle and “fun,” while Klean reads calmer and more mid-focused. The Awaken Dawn MS offers bigger bass and air; Klean counters with better build and accessories—great as a gift set. Versus value champs like Waivering Abyss, KZ EDC Pro, or sub-$10 curios, Klean sounds better but the gap narrows when price is king; step-ups like AFUL Explorer, Moondrop Aria, or Moondrop May can out-resolve or reshape the profile if spending more. A light EQ nudge (more sub-bass, slightly tamed mid-treble) dials it in. Final take: full recommendation on merit and build, with rough scores around Bass 8, Mids 7.5, and an overall solid ~7.7/10 for value.
