Our Verdict

HyperX Cloud Alpha S

Razer Kaira X

The HyperX Cloud Alpha S are somewhat better-wired gaming headphones than the Razer Kaira X. The HyperX are more comfortable, better built, and compatible with companion software that offers an adjustable mic level. Their audio cable and microphone are also detachable.
