Trebble and air is pretty great at this price. But Shouty, and colored.

Heavy-bass 1+1 hybrid with pushed upper mids and a fatiguing ~5k peak; works best with EDM but lacks refinement and stage. Huge bass with lifted vocals suits EDM and bass-centric tracks. Overcooked upper mids/5k peak and bloated mid-bass cause fatigue with recessed mids and cramped stage.
Youtube Video Summary

CCZ Harmony is a $26 1+1 hybrid that looks slick with its faceted faceplate and rubberized wing, but the stock cable is flimsy and tangle-prone. The tuning is a throwback: a very heavy bass shelf (Rosefinch-like) that runs into the mids, with the balanced armature pushed forward to keep vocals on top. Upper mids around the ~5k region are emphasized, which can turn edgy at volume despite the huge low end. The result is exactly what the graph promises: lots of bass with vocals on top, fun for short bursts but not ideal for long sessions.

Genre fit matters: EDM fares better when energy spreads higher, yet the old-school shelf that bulges both sub-bass and mid-bass softens impact and thickens the mids. Treble extension exists but is often masked by the low end; separation from the BA is only marginal and the soundstage sits in-head. For bassheads who want forward vocals at a budget price it can be entertaining, but those seeking balance, dynamics, or technical finesse will find it limited.

The CCZ Harmony (BC01 Pro) is an entry-level hybrid using a 1DD+1BA configuration (10 mm PET dynamic + custom BA), rated 16 Ω/105 dB, and housed behind a zinc-alloy faceplate. Street pricing sits around $26.99, placing it firmly in the ultra-budget category. Specs and materials are consistent across listings and product pages.

Tonal balance is broadly V-shaped: a sub-bass-biased shelf provides weight, while a noticeable dip around 700–800 Hz recesses lower mids before the BA adds presence from ~1 kHz. This yields punchy low-end for EDM and pop, clear enough upper-mids for vocals, but a slightly muffled midrange on dense mixes; treble is smooth rather than biting. These traits are documented in product measurements/impressions and align with the published specs.

Technicalities are competitive for the price: it’s easy to drive and offers acceptable imaging and stage for casual listening and budget gaming, according to community impressions. Fit/isolation are decent thanks to the shell geometry and metal nozzle, but micro-detail and macrodynamics remain average versus higher-tier sets. Overall value is solid in the sub-$30 bracket, with strengths in bass impact and comfort offset by recessed lower mids and only modest resolution.
