front side faces your ear canal and the back side with intuitive button rests behind your ear.
2. Move the earbuds upwards or downwards until the earbuds fit securely and you can hear the sound well.
If the fit feels loose, you can choose between M or L size ear grips to enhance stability.

on for 2 seconds and then go off.

you can proceed to pair with the second device.
