JBL Quantum 400
Score: 88/100
HyperX Cloud Alpha Wireless
Score: 90/100Rankings

The HyperX Cloud Alpha Wireless offers a rugged aluminum build, memory-foam comfort, and an unprecedented 300-hour battery life, paired with dual-chamber drivers and DTS spatial audio. It excels in endurance and sound quality but lacks wired connectivity, Bluetooth, and active noise cancellation.

The JBL Quantum 400 is a wired over-ear headset delivering high-fidelity audio, virtual surround and a feature-rich software suite, aimed at competitive gamers and streamers who don't need wireless capability. Its strong sound and mic performance are offset by a lack of ANC and Windows-only software.
