The Quantum 120 is a 3.5mm wired headset with 50mm carbon dynamic drivers, a detachable 6mm cardioid boom mic and a light 265g build that stays comfortable for long sessions. It plugs into PCs, consoles, controllers and phones with no dongle or battery to manage. The plastic build feels thin, the mic is only serviceable, and the tuning favors games over music.
