JBL Quantum 120 Over-Ear Wired Gaming Headset

The JBL Quantum 120 is a wired over-ear gaming headset built for players who need reliable positional audio and clear comms across every platform. Driven by 50mm carbon dynamic drivers with Hi-Res Audio support and JBL Quantum Spatial Sound, it's tuned to surface the audio cues — reload clicks, shifting footsteps — that decide outcomes.

• 50mm carbon dynamic drivers with JBL Quantum Spatial Sound and Hi-Res Audio support for detailed, positionally accurate audio
• 6mm detachable cardioid boom mic with noise reduction via JBL QuantumENGINE; windshield foam included
• JBL QuantumENGINE software for custom EQ profiles per game, real-time sound visualisation, and mic optimisation
• 3.5mm wired connection — compatible with Windows, Mac, PlayStation, Xbox, and Nintendo Switch
• Lightweight build with silicone headband and breathable fabric ear cushions for extended sessions
• In the box: headset, detachable boom mic, windshield foam, quick start guide and warranty card

A solid pick for multi-platform players who want spatial audio and software control without going wireless. The JBL Quantum 120 is a wired gaming headset from JBL's Quantum lineup, available here at Overkill.
