Charging basics

A complete charging cycle takes about 3 hours. Before using the headphones for
the first time, charge their rechargeable battery for a complete charging cycle
3h
without interruption.
When the battery is almost empty or when the headphones are being charged,
the LED lights up or flashes as indicated in the table below and a voice prompt
announces the charge condition of the battery. When the battery charge drops
to a low level, a voice message prompts you to recharge the headphones to
avoid call and music disruptions.
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.
