JBL Quantum 350 Wireless

To reset a Quantum headset, you need to connect the product to your computer and open the QuantumEngine.

When you have the QuantumEngine open, go to the "System Software" tap and press "Restore Factory Settings".

Only products that are compatible with the QuantumEngine can be reset this way.

You might have to add a USB extension dock to get the JBL Quantum 350/600/800/810 dongle as close to the headset, or place the common sources of interference (e.g. routers, Wi-Fi speakers etc.) as far from the JBL Quantum 350/600/800/810 dongle.

Ensure that only one voice chat application is in use while in-game. Be sure you hear a click when the microphone is flipped down. The microphone will only function when it is flipped down fully. If you see a red LED on the microphone, it is muted.
