I hope this sort of thing is safe. As a precaution I would have it charged a few feet away at least; I'm not sure I'd want a "cone of energy" being projected at my body. Although this will be nice, if only to save the delicate USB port from constant connecting and disconnecting.
Sir, c'mon now! What's wrong with microwaves zappin' a few people as they halt to tie shoelaces? Don't tell me you're gonna complain about wearing a Tesla coil-headset?!! Just think - you too could look like Boris Karloff! "Do you have Gold bolts-in-the-neck? I'm tired of this dingy silver stuff."
