SOLUTION
Make sure the earbuds are properly placed in the charging
case. To help preserve the battery life, the case should be
closed while the earbuds are charging (see page 34).
Make sure there is no dirt or debris covering the charging
contacts on the earbuds or the charging pins in the case.
Make sure the stability bands are positioned on the earbuds
correctly (see page 19). If the bands are positioned
incorrectly, the charging contacts on the earbuds may not
align with the charging pins in the case.
Make sure the USB cable is correctly aligned with the port on
the charging case.
Secure both ends of the USB cable.
Try another USB cable.
Try another wall charger.
If the earbuds or charging case have been exposed to high
or low temperatures, let the earbuds or case return to room
temperature. Charge again (see page 34).
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 35).
Make sure any charging case accessories are properly
installed and don't prevent the USB cable from securely
connecting to the port on the charging case.
Change the voice prompt language using the Bose Music
app (see page 12). You can access this option from the
Settings menu.
