Youtube Video Summary
KZ Zenith arrives as the flagship single dynamic with a full-alloy shell and a semi-open mesh that vents into the chamber. Four switches provide fine control: 1–3 add roughly +1 dB each to sub-bass, while switch 4 raises overall SPL for low-power sources. The show, however, is the pairing of KZ’s refined 2024 “swoopy” curve with a more capable driver—cleaner note definition, stronger separation, and sharper imaging that blur the line with hybrids. Turned up a bit, staging opens and the presentation stays smooth, without the metallic edge older KZ tunings were known for.
Bass is the full type—real sub-bass and mid-bass carried cleanly into the mids—now with better texture and nuance; the three switches let genre-hoppers nudge it from tidy to fun. Mids benefit from improved attack-to-decay “note completion,” giving vocals and instruments extra focus and microdetail. Treble is about as neutral and transparent as KZ has done—seamless, extended, and non-fatiguing; some may notice a brief 7–8 kHz glare that settles with playtime, and there is a curious 12 kHz dip in measurements that is not a deal-breaker in listening. For the price, Zenith offers a clear window into the technical finesse usually associated with pricier single-DD sets.

Youtube Video Summary
Op.24 goes in with a quirky two-tuning “turntable,” but both positions behave almost the same where it matters. A big 3–4 kHz elevation shoves door kicks, gunfire, and certain effects to the front, creating a shouty and fatiguing presentation that masks crucial cues. Imaging itself isn’t terrible—depth perception can even edge out Simgot’s EG280—but the weak points are separation and layering: simultaneous cues merge into a “mashed potato” blur, so tracking multiple targets behind cover becomes unreliable. The stock recessed 2-pin cable also disappoints, though it was tested here with a consistent aftermarket cable.
In Apex Legends, the overcooked presence region turns gunfire and abilities into a flashbang effect that drowns out slides, taps, and flanks, resulting in a C+. In Valorant, deathmatch feels okay at first thanks to decent imaging, but team scenarios expose the same weaknesses: abilities (e.g., orbs, flashes, concussives) spike uncomfortably and layering collapses when two sets of footsteps stack behind a wall—settling at a B-. With scores this middling, CS2 and CoD weren’t pursued; overall, Op.24’s switchable tuning doesn’t fix the core balance issues that hold it back for competitive gaming.

The ooopusX Op.24 is a budget hybrid with a 2DD+4BA array and a physical two-position tuning dial that switches electrical load between roughly 15Ω and 27Ω, indicating distinct filter networks for its modes. Core specs are ambitious for $49.99 (quoted sensitivity 127 dB/Vrms, 10–40 kHz FR), and the housings remain lightweight for long sessions. Fit and ergonomics are straightforward, reportedly ~5.2 g per side, which helps stability and isolation in daily use.
Tonally, Op.24 targets a Harman-style balance with a safe mid/treble contour and modest sub-bass lift; independent reviews describe consistent but unadventurous resolution, with the dial providing small, audible shifts rather than wholesale retunes. Technical performance is competent for the class—detail retrieval and imaging are respectable, while stage size and microdynamics are average—placing it as a solid value pick rather than a segment disruptor. Overall, the package reads as a pragmatic daily driver with useful tuning flexibility rather than a specialist, aligning with assessments from multiple third-party reviewers.
