Resetting your product | Bose QuietComfort Ultra Headphones (2nd Gen)
Reboot your headphones.
This reset will not erase your product settings.
- If the USB charging cable or audio cable is connected to your headphones, disconnect it.
- Connect a USB charging cable and charger to a power outlet. You can also connect the USB cable to a USB port on a computer that is powered on.
Note: Do not connect your headphones to the USB cable yet. - On your headphones, press and hold the Power/Bluetooth® button.
- While continuing to hold the button, connect the USB cable to the left earcup. The Power light on your headphones will quickly blink twice.
- Once connected, wait two seconds and then release the Power/Bluetooth button.
Tip: If your headphones don't respond after this, reset them a second time.
