An other question ?

How do i connect my headphones on a daily basis?

Once your headphones and your phone are paired with each other, just check that bluetooth is activated on your phone. The small bluetooth icon should be visible on the status bar at the very top of the phone screen.
Then take your headphones out of the charging box, the headphones will connect almost instantly.
If the light stays blue, it means the earbuds couldn't connect to the phone. In this case, go to the bluetooth menu of your phone and click on TWS 100 in the list of nearby devices.
