Charging headphones
Charging the vFree before using for the rst time is recommended in order to maximize battery life. Low
battery is indicated by the LED status indicator ashing red approximately every 10 seconds.
To begin charging, connect the USB cable (micro USB end) to the port at the bottom of the left ear cup.
Connect the other end of the USB cable to any charge capable USB port or a USB-style charger. Your
vFree headphones will begin charging, as represented by the red LED status indicator. Once charging is
complete, the LED status indicator will illuminate green.
