CHARGING
Charging the Buds
IMPORTANT Before using the Buds for the first time, make sure to fully
charge the Buds. Place the Buds in the case, making sure that the contacts
engage on both Buds. The Red LED on the Buds will blink while they are
charging. When the Red LEDs on the Buds turn off, charging is complete.
Charging should take roughly 1 ½ hours. Note that red LEDs should be on
for both Buds if they are charging properly.
NOTE
1. Close the cover on the case while the Buds are charging. This will help
assure the contacts are making a solid connection.
2. LED case status. While the Buds are out of the case, the LED on the case
will be off. When then Buds are placed in the case the White LED on the
front of the case will go on and indicate the charged status of the case.

Charging the Case
When you put the Buds in the case, the White LED on the front of the
case will indicate the battery status in the case (see above). If charging is
indicated, you have 2 options for charging.
Using the USB cable
1. Connect the Micro-USB end into the case’s Micro-USB jack. The jack is
located on the underside of the case.
2. Connect the USB end into a charging source such as a PC/Mac, or
other 5V USB charger.
Charging will take about 1 ½ hours.
Using a Wireless Charger
1. Connect your Wireless Charger to a power source. You may not need to
plug in the charger if it has a built in battery.
2. Place the Charging Case, with or without the Buds, in the center of the
charger. The White LED will show:
White LED flashes - battery is charging
White LED solid on - charge is complete
Charging will take a little longer than via USB. If the Buds are in the charging
case, they will charge also.
