FAQs & How-Tos

For JBL Quantum 100/200/300 models, they do not offer Game-Chat audio dial function.
To get the Game-Chat dial feature, you need JBL Quantum 400, and up, then you can adjust game-chat balance by rotating the dial-up and down.
For models that support Game-Chat dial, when you rotate the dial, you will feel a notch that indicates 50% game and 50% chat. Or you can see the status on the top bar of the JBL QuantumENGINE.Was this helpful? Thank you for your feedback! -
Make sure your headset is configured correctly in your Windows settings. The setting should normally be JBL Quantum *Game* to experience QuantumSURROUND.

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!

Make sure the headset volume control is turned up. Rotate the volume wheel on your headset to increase the volume. If you're using the USB dongle, check that the correct playback device is selected under Control Panel > Sound > Playback. Select the proper playback device, right-click, and select "Set as Default Device". Check the computer volume levels and make sure it is not muted or turned all the way down.
