HOW TO CHARGE
The battery has approximately 5 hours of battery life.
When the sound becomes intermittent, you hear Low
Battery, or if the LED indicator flashes 3 times every 20
seconds, it means the battery is running low. Once this
happens, you have about 5-10 minutes of use before
the earphones power off automatically.
Charge the batteries by:
Using the provided USB/micro USB cable, connect
the micro USB end of the charging cable to the
micro USB charging port and the standard USB end
to a PC USB port or USB charger. You will have to lift
the rubber covers. Lift the rubber cover from the
end farthest from the ear rests.
The LED indicator will be red while charging. It will
turn blue after 1-2 hours. The battery is now fully
charged.

Never disassemble or modify your headset for any
reason. Doing this may cause the headset to
malfunction or become combustible. The damage to
your device can void your manufacturer’s warranty.

cause serious damage. Water damage to your
device can void your manufacturer’s warranty.
