Charging basics

A complete charging cycle takes about 1.5 hours. Before using the
1.5 h

complete charging cycle without interruption.
It is recommended to charge the headphones using only the supplied
USB cable. If you are charging using an external USB-power adapter, it
is recommended to use an adapter with an output rating of 500 mA or
higher.
