Overview

  • 50mm carbon dynamic drivers for rich JBL Quantum Spatial Sound
    The 50mm carbon dynamic drivers use a unique carbon damping material to create a rich, expressive sound experience that together with Hi-Res Audio support, make crucial audio cues stand out clearly when each split-second counts.
  • 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, reduce keyboard noise, optimize the mic’s performance and noise reduction. JBL QuantumENGINE lets you create custom profiles for every game, so your setup always plays 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.
  • 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.
  • Universal design for multi-platform
    Windows, Mac, PlayStation, Xbox, Nintendo Switch —no problem. The JBL Quantum 120 headset works with them all with the 3.5mm audio cable.
  • Sustainability
    JBL is committed to making more sustainable products. So the JBL Quantum 120 headset is packaged in FSC-certified paper packaging printed with soy ink. The plastic we use is partly recycled, which reduces waste.
