You wanna listen to the latest pop song while telling everyone you're really into neo-classical metal? Headphones. You wanna listen to atonal New York jazz while sitting on the couch with your jazz-hating spouse? Headphones. You wanna send a signal to everyone that you're not wanting to make friends on this bus trip? Headphones, headphones, headphones.
