I had to sign up for this because I can't stand knowing facts and not being able to show them off. You are given headphones using the same principle to wear during an MRI scan so the technicians can tell you off for moving without the risk of having your ears ripped off by the magnetic forces between the scanner and the permenant magnets in ordinary headphones.Nice, Amish earbuds!
Woo aside, that is quite a neat product. I wonder if it has a practical use? And how it sounds?
