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.
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.
