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.

JBL Quantum ONE and Quantum TWS: How do I clean my headset?
You can clean it by wiping it gently with a damp cloth. Take extra care not to let water leak into the speaker chamber, as it will damage the speaker drivers.
Pairing Issues
Try a manual pairing of the headset and the dongle.
Hold the power button in the "On" position for 5 seconds on the headset, and then hold the button on the dongle for 5 seconds. This should force a manual pairing, allowing the PC to again recognize the headset.
Be sure to check multiple USB ports (to confirm it’s not an issue with the USB port).
If the dongle can’t be manually paired either, please contact customer support.
