Our Verdict
JBL Quantum 400
HyperX Cloud Alpha
The HyperX Cloud Alpha are better wired gaming headphones than the JBL Quantum 400. The HyperX are much better built, offer a more comfortable fit, and have a better-balanced sound profile. Their microphone performance is fairly similar overall. Meanwhile, the JBL offer a more customizable listening experience overall, thanks to their feature-rich Quantum Engine companion software, and they are slightly better at blocking out ambient noise.
