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.

Reviewer Score
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.
