Setting up the earphones for the first use
Make sure that the charging case is charged, if not, please charge it. Put both
earbuds in the charging case and the indicator will light up to indicate that there is
power. If it doesn’t light up, it means that the charging case is out of power.
Take the earbuds out of the charging case and put them on. They will
automatically turn on and automatically pair with your device (works with previously
paired devices).
Turn on the Bluetooth on your device and pair with the earphones (voice
prompt "Connected").
When using the earbuds for the first time or after a long time without using,
please charge the charging case and earphone. Please keep it in an unobstructed
environment within 10 meters. Otherwise, earphones may be stuck and
disconnected.
