Battery charging
When the headphones stops emitting any sound, or the sound gets cut, it is time to recharge the battery. The headphone
includes a built in Li-Polymer battery which should be charged when the battery is nearly exhausted. Use the supplied USB
cable and connect the micro USB end to the input located on the left side of the headphone and the USB end to a PC or a
AC USB adaptor.
1. To charge with a computer, connect the other end to your PC.
2. Or, to charge with a 5V AC/DC adapter (not included); connect the other end to an adapter. Plug the adapter into an AC
outlet. The charge indicator will light up in blue while charging.
3. The charging time is approx. 1:30 hours.
Note: Do not charge the battery until it has been completely discharged. At the same time, do not disconnect the USB
cable until the battery is fully charged.
