Here's my favorite story of the week. Apple had to put out a press release warning iPhone and iPod users that those little earbuds could come with a pop.
Apparantly, they are prone to building up static electricity and the result could mean more than your fingers snapping to the beat.
Don't worry, it's not likely to lay you out flat. More likely, the risk is just a pop in the ears similar to the kind you get from skooching around on the carpet in your socks. Still, who wants that in your ears.
