A while back I wrote a little piece on human machine interfaces and a number bits of research that are on going in progressing the way we connect to our machines. There is a bloke who has taken this to the next level by getting his headphones built into his ears and neck.
He went as far to find a body modification artist to do the procedure because no doctor or plastic surgeon would touch him with a barge pole.
This is either real commitment to your music or a real hate of those awful Apple earbuds. You decide.
