Our Verdict

HyperX Cloud Alpha

Cooler Master MH751

The HyperX Cloud Alpha are slightly better than the Cooler Master MH751. The HyperX are comfier, significantly better-built, and more stable on the head. Their boom microphone does a better job of filtering out background noise, though its recording quality is inferior to that of the Cooler Master. The Cooler Master also block out a little more ambient noise and have an easier-to-use control scheme.
