SOLUTION
Make sure the USB cable is correctly aligned with the port on
the charging case.
If the charging case battery is fully depleted, make sure the
USB cable is attached long enough for the case to gain an
initial charge. If you remove the cable and the charging case
status light goes out, reattach the USB cable.
Secure both ends of the USB cable.
Try another USB cable.
Make sure the charging case is closed. To help preserve the
battery life, the case should be closed while it's charging.
Try another wall charger.
If the charging case has been exposed to high or low
temperatures, let the case return to room temperature.
Charge again (see page 33).
Change the voice prompt language using the Bose Music
app (see page 14). You can access this option from the
Settings menu.
Make sure voice prompts are enabled using the Bose Music
app (see page 14). You can access this option from the
Settings menu.
Make sure you have given the earbuds access to your
contacts in your mobile device Bluetooth menu.
Make sure the earbud nozzles aren't blocked
(see page 20).
