No power

If your product is connected to power but does not appear to be receiving power, try the following:

Be sure the headset is powered on.

The headset is on when the power switch on right ear cup is in the center position. If battery has enough charge, a green LED will glow just below the volume down button, located on the right ear cup bottom.

Check if the battery is charged.

Be sure the battery is not depleted. For more info see, Checking the remaining battery charge and Charging your headphones.

Check for and install any available product updates.

On a computer, visit and follow the instructions to ensure your product has the latest features and enhancements. See Updating the software or firmware of your product.

Use a wall outlet USB charger to charge your headset.

Charger specifications vary. Be sure to use a UL/CE approved charger that provides 1 Amp. (Tip: Chargers that provide lower amperage (like a computer USB port) will take longer to charge your headset.)

Reset your product.

Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more info, see Resetting your product.
