Five hundred shekels is a lot to lay out for headphones. But these babies are worth it. The ear buds deliver Kleer Corporation's patented, uncompressed sound, wirelessly. (You attach a transmitter, smaller than a deck of cards, to your sound source an iPod, TV, stereo or anything else with an out jack then synch the earbuds.) The earbuds and transmitter come in a pocket-sized case that will recharge the unit three times when you're on the road. Price: $499
