SOLUTION
Make sure your mobile device is compatible with the Bose app
and meets minimum system requirements. For more
information, refer to the app store on your mobile device.
Uninstall the Bose app on your mobile device. Reinstall the app
(see page 12).
Make sure both ends of the USB charging cable are securely
connected into the ports (see page 35).
Try a different USB-A wall charger, USB cable, or AC (mains)
power source.
If your headphones have been exposed to high or low
temperatures, let the headphones return to room temperature
and try charging again.
Power your mobile device off and on, then try connecting again.
Clear the headphone device list (see page 30). Delete the
headphones from the Bluetooth list on your mobile device,
including any duplicate listings labeled LE (Low Energy).
Connect again (see page 27).
Reset the headphones (see page 55).
Ensure that Spotify is open on only a single connected device. If
you are logged in to the same Spotify account on multiple
connected devices, log out of or quit Spotify on one of them.
Power off the headphones, then power on again (see page 14).
If using the Multi-function button, try using the Bose app to
adjust the noise cancellation level.
Power off the headphones. Put the headphones on, then power
on again (see page 14).
Make sure the right earcup is fully covering your ear.
Brush aside any hair or remove any clothing covering your right
ear before putting the headphones on. Hair or clothing can
prevent the headphones from detecting that they're on
your head.
