Charge the battery

The headset has an internal, nonremovable, rechargeable battery. Do
not attempt to remove the battery from the headset, as you may
damage the headset.

1. Connect the charger to a wall outlet.

2. Connect the charger cable to the charger connector. The indicator

light is red while charging. It may take a while before charging starts.
If charging does not start, disconnect the charger, plug it in again,
and retry.

Charging the battery fully may take up to 1 hour and 15 minutes.

3. When the battery is fully charged, the indicator light turns green.

Disconnect the charger from the headset and the wall outlet.

The fully charged battery has power for up to 13 hours of talk time, up to
10 days of standby time, or up to 13 hours of music playing time (or 75
minutes of music playing time with 20 minutes charging). However, the
times may vary with different compatible Bluetooth devices, usage
settings, usage styles, and environments.

When battery power is low, the headset beeps at regular intervals, and
the indicator light slowly flashes red. Recharge the battery.
