Make sure the earbuds are fully charged. Do this by
charging the earbuds in the charging case. Also plug
the USB-C charging cable into the USB-C port on the
charging case. Plug the other end of the cable into a
power source and charge until all 4 LED lights on the
charging case are stable.
PAIRING EARBUDS AND DEVICE
1. Take out the earbuds from the charging case.
The earbuds will automatically power on and pair
with each other. When blue/red lights flash alterna-
tely, the earbuds are ready to pair with your device.
2. Turn on the Bluetooth function on your device. Select
Defunc TRUE AIR in the Bluetooth list to pair the
earbuds with the device. The earbud lights turn off
when the earbuds are paired. The earbuds will
automatically pair with a previously connected
device when powered on again.

for auto-power on.
