CHARGE THE EARBUDS
Make sure that the charging case has battery life.
Put the earbuds in the charging case. Close the cap.
CHARGE THE CHARGING CASE
Plug the USB-C charging cable with the USB-C
port on the charging case. Plug the other end into
a power source.
LIGHTS ON THE CHARGING CASE
Each light equals 25% battery life on the charging case.
When each 25% is reached, the corresponding light
becomes stable, and the next starts flashing. When
charged to 100%, all 4 lights are stable.
GENERAL TIPS
• Because of interference with other Bluetooth
devices, the earbuds can get disconnected from
each other. If you experience this problem, put the
earbuds in the charging case and close the cap. After
a few seconds, open the cap and start using the
earbuds again.
• Hold the earbud stem when putting or adjusting the
earbuds in your ears. This way you avoid touching the
sensitive touch area which controls different functions.
• The volume affects the capacity of the battery. If you
play your music with lower volume, the battery will
last longer.
