These are wireless bluetooth headphones. I find the fact that they do... um... have a wire... but it just goes around in a circle adorable. 

This must be how my dad felt when I used to borrow his old reverse Polish notation calculator then programed my TI to do arithmetic the same way.

(Also if it's called "reverse Polish notation" wouldn't that imply "Polish notation" is just doing it the normal way?)
