FAQs & How-Tos

How to avoid WiFi interference for your headphone

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.

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.

Which products are supported by the JBL QuantumENGINE software?
JBL Quantum 300, 350, 400, 600, 610, 800, 810 ONE, TWS and Stream are working with the QuantumENGINE
How to set up your microphone

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.
