Charging the earphones
You can charge the earphones regardless of their power state (on or off).
1. Open the micro USB cover to access the micro-USB input.
2. Connect the micro-USB plug of the charging cable to the micro-USB input of
the headphones.
3. Connect the USB plug to the USB port of your computer. If you are using an
external power adapter, connect the USB plug to the power adapter or to the
USB car charger adapter, and connect to the power source.
The LEDs flash/light up depending on the battery life of the earphones.
CHARGING TIME
The earphones utilize an intelligent battery charging technology that
prevents overcharging.
For faster charging, charge the earphones while they are switched off. For
