These headphones can be charged using the USB cable supplied in the
®
box. Plug the micro-USB end of the cable into the connector on the
®
control module. The USB end of the cable can be plugged directly into a
computer, or it can be plugged into a USB wall charger to allow charging
from an electrical outlet (like the charger that comes with the Apple
iPhone). Allow up to two hours for the headset to fully charge. While
charging, the power status indicator will flash amber. Once fully charged,
the power status indicator light will turn solid green.
The battery will provide up to 16 hours of use per charge.
The power status indicator light on the control box will be solid green until
there is approximately 3 hours of battery life remaining. At that point, the
light will begin flashing green. When the light goes off, battery power has
been fully depleted.
