Aww, thanks.

- Like listening to music? This might be for you.

In class, wire your phone through your hoodie, making the ear buds go under the bottom, all the way back through the top, and through the sleeve. Then, hold a single bud in your hand and put it up against your cheek as if you were bored in class.
Make sure the volume isn't too loud, or someone else might here and report you. Also, make sure your ringer is off. Seriously, if you're going to have your phone on and in use, do it strategically.

Additionally, anyone with long hair can just use that to their advantage.
