How to Charge
If you can hear the voice prompt say "Low battery" or see the LED blinking RED, you will need to charge your earbuds.
Charging the earbuds in the charging case:
Place the right and left earbuds in their respective positions in their charging case. The LED on both earbuds and the charging case will be RED to indicate that they are charging. The LED on the case will turn GREEN when charging is complete.
Charging the Case:
Insert the micro USB (smaller) end into the charging port on the back of the case and the USB end into a power source. You can either use the included charging cord or any USB to micro USB cable to charge. The LEDs on the case will light up RED when the case is charging and turn GREEN when the case is fully charged.
