Vibrating Headphones

Now I haven't quite worked out why on earth you'd ever need your headphones to vibrate, but someone came up with the concept and released a pair. And 12 hours of vibrating pleasure with one battery no less.

Maybe the sound quality was so bad, they wanted to distract you - I have no idea. If anyone else has a clue, please fill me in....

More details here if you're really interested.
