JBL Quantum 520 is a wireless gaming headset designed to combine immersive audio with a more expressive visual identity. A transparent outer shell is paired with bold colour accents, while the silicone headband and breathable fabric ear cushions are designed for long sessions. Spatial sound is used to make directional audio easier to follow, with a detachable boom mic keeping communication clear. Sound, mic and profile settings can also be customised through JBL QuantumENGINE.
