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.Was this helpful? Thank you for your feedback!

How to switch between Game and Chat balance
Yes, you can adjust game and chat audio balance by rotating the dial up and down. When you rotate the dial, you will feel a notch that indicates the balance is 50% game and 50% chat.

Why are my headphones shown as “speakers” on Windows?
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.
