You know how headphones have little L and R markings on them?
Headphones are generally shaped to work best on the ear they are designed for, yet I looked around the plane this weekend and saw a bunch of people with their headphones on backwards – sticking out at weird angles.
It’s really funny when they have the in-ear style pointing away from their ear opening and back towards the cup of their ear. Or the big over the ear headphones like the noise canceling Bose mangling their ears with their ear lobes sticking out.
