    The “Speaker” mode allows the JBL QuantumENGINE to receive more than two channels of audio. It also prevents some applications from adding extra signal processing intended for other headphones, which would negatively impact the performance of the JBL QuantumSURROUND or JBL QuantumSPHERE 360 technology.

  • The story behind our Quantum name

    We wanted the name to reflect this futuristic inspiration married with cutting-edge technology. The Quantum name was ultimately chosen as it conjures images of both the technology aspect through the advances in quantum computing but also a very organic feel with reference to quantum physics and the science behind building upon small elements to make massive improvements.

  • Non-removable microphone feature

    We've intentionally designed the flip-up boom mic to stay affixed to the headset. We know from experience that losing or breaking the detachable mic is never fun. Therefore, we designed the mic to fold neatly into the headset - this design also allows the mic to automatically mute when elevated. If you're wanting a detachable mic, please check out the Quantum 100 or the Quantum ONE.

  • Mic Monitoring Support

    The Quantum line does not have sidetone/mic monitoring so you will not be able to hear your own voice through the headphones.
  • How RBG lighting work for console games

    JBL Quantum 400 and ONE are compatible with USB C to A cable to enjoy PS4 console with RGB Lighting on, and Quantum 600 and 800 with wireless-enabled by USB dongle also gives lighting moment on PS4 console games.

    *NOTE that RGB will not light up when connecting with 3.5mm cable to any device (PC, Console, Mobile, etc.) because the cable doesn't have power enough for the RBG lighting.
