JBL QuantumENGINE
Use your device-specific JBL QuantumENGINE dashboard to customize your preferred sound profile, spot where in-game sounds are coming from with a real-time sound visualizer, activate JBL Quantum Spatial Sound, reduce keyboard noise, optimize the mic's performance and noise reduction. The free PC suite JBL QuantumENGINE lets you create custom profiles for every game, keeping your setup tuned to your strengths. It works on all platforms and connects all your JBL Quantum headsets simultaneously.
JBL Quantum Spatial Sound
JBL Quantum Spatial Sound, powered by JBL QuantumENGINE drops you right into the game. By pulling in more in‑game audio detail, it builds true-to-life reflections and reverb, so sound moves naturally around you. Tuned across multiple frequency ranges, it delivers pinpoint positional audio—so you hear footsteps before they’re on screen, track enemy movement in real time, stay locked into the action, and react faster when the fight flips.
Cardioid Noise Cancelling boom mic
The 6mm unidirectional mic with cardioid pattern makes sure your team can always hear you loud and clear but doesn't hear your keyboard thanks to the noise reduction technology through JBL QuantumENGINE. And the mic is also detachable for extra convenience.
Dual Wireless Connection
Dual wireless lets you choose between 2.4 GHz for low-latency gameplay or Bluetooth 5.4 for seamless everyday use, giving you a stable, responsive connection no matter how—and where—you play.
Low-latency wired USB Audio
USB-C audio gives you a stable, ultra low-latency connection designed for competitive moments, keeping your reactions tightly in sync when you want the most dependable performance your setup can deliver. Choose the cabled connection to enjoy extreme sound clarity thanks to Hi-Res audio support.
Light and comfortable design
The high-quality silicone headband and breathable fabric ear cushions keep your fit secure and comfortable, reducing distractions so you can stay locked into the match no matter how long your session is.
