Competitive Gaming Audio

The JBL Quantum 300 is a wired over-ear headset built for competitive gaming where sound cues determine survival. It delivers JBL Quantum Surround audio engineered for accuracy across PC, Mac, Xbox, PlayStation 4 and Nintendo Switch. A boom microphone with echo-cancelling technology isolates your voice from background noise for clear team communication. Memory foam cushions wrapped in soft PU leather support comfort during marathon sessions.

Multi-Platform Connectivity

This headset fits a build through a hardwired 3.5 mm audio cable and an included USB audio adapter, freeing you from driver hassles on consoles. The flip-up boom mic mutes instantly when raised, keeping desk space clear when chat is not needed. No embedded battery means zero charging downtime and no wireless interference to manage. The fixed cable design suits stationary setups where a reliable tether is preferred over freedom of movement.

Passive Thermal Comfort

Over-ear cups with memory foam create a passive seal that manages heat buildup during long matches without active cooling or noise-cancelling electronics. The 32 ohm impedance allows the headset to run efficiently from controller ports or the USB adapter without demanding extra amplification. With no battery or wireless radio, power draw is negligible and there is no transmitter heat to dissipate. The lightweight frame reduces clamping pressure that can cause fatigue over hours of play.
