You're taking the train to work. You hear the rumbling of the train tracks, the chatter of other passengers, the occasional cough and sneeze - you just want to zone out. You reach into your messenger back and dig for your saviour: A pair of wired earphones.
Pulling it out, however, you are greeted with a bunch of tangled wires that do nothing but add on to the frustrations of your commute.
What if, instead, you can just pop open a case, pull out two earbuds, and place them in your ear and listen to your own world?
Soon, you can.
