So it seems the thing to do these days as a teen is to share your ipod – walk around with someone, each of you having one earphone attached to the one ipod. Seems like a slightly looser version of the 3-legged race to me.

Thing is, though, lots of friends are in trios or more. So what I want to know is, has someone invented earphones with more than just 2 listening bits? Or a double-jack or similar so that more than 1 pair of earphones can go into the one plug? This would seem to be the next innovation that ipods bring about.
