headphones if the baery is depleted or to charge the headphone baery
(see page 35).

connected to an external power source.
• To continue listening to audio on your source device when the headphone baery
is depleted and a Bluetooth connection isn’t available, connect both the USB cable
and the audio cable (see page 33).

2. Connect the other end to a USB-A power source such as a computer or
wall charger.
