Battery will not charge

If your product is plugged in to charge but the battery level does not increase or your product does not indicate that the battery is charging:

Battery will not charge | Bose QuietComfort Ultra Headphones (2nd Gen)

Reboot your headphones.

This reset will not erase your product settings.
  1. If the USB charging cable or audio cable is connected to your headphones, disconnect it.
  2. 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.
  3. On your headphones, press and hold the Power/Bluetooth® button.
  4. While continuing to hold the button, connect the USB cable to the right earcup. The Power light on your headphones will quickly blink twice.
  5. 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.

Try a different USB-C cable.

Try charging your product with another USB-C cable to determine if there is an issue with the first cable.

Try a different charger.

Charge times can vary based on the charger. Chargers with a higher current rating generally charge products faster than those with a lower rating. Chargers typically list a current rating on the label in amps (A) or milliamps (mA). A current rating of 1 A / 1000 mA or higher is recommended.
