Corsair M75 Air Review

The M75 Air is Corsair's ultralight spin on the M75 line, cutting weight to 60g with a perforated shell while keeping the 26,000 DPI Marksman sensor and up to 2000Hz wireless polling.

Where the standard M75 Wireless chases a filled-in ergonomic feel, the M75 Air is Corsair chasing the sub-60g wireless race directly. The honeycomb-style perforated top and bottom shave grams without sacrificing shell rigidity, and Corsair kept the same Marksman sensor and optical switches from its higher-end mice rather than cutting corners to hit the weight target.

Who It's Built For

Players who want Corsair's flagship sensor and switch quality but prioritize the lowest possible wireless weight.

Comparison to Alternatives

Against the Corsair M75 Wireless already in this catalog, the Air trims about 29g by perforating the shell, at the cost of some structural solidity. It sits in the same weight class as the Glorious Model O 2 Pro and Pulsar X2H, competing directly on the sub-60g wireless shortlist.
