Putting the earphones on
Check the markings on the earphones for the left and right sides to make sure they are worn in the correct ear, and insert them into your ear.
Move the earphones to adjust them so that they fit your ears when you put them on.
If the earphones seem like they might come loose when you shake your head a little while wearing them, try using different silicone sleeves. This will help prevent them from falling out.
