What is the easiest way I can sneak my iPhone into class and listen to music?

I have the iPhone headphones only… Please help me

Where your hoodie with the hood on. Your earphones have to go inside your shirt so it's hidden and the professor won't see the earphone wire.

Put your phone in your pocket and run the buds from under your shirt to your ears. The wires shouldn't show.

Put the I phone in your pocket and slide the ear buds into your sweater sleeve and make them rest on your palms then put your head on your palm (bend your elbow) while listening to music from the buds
