The Bluetrek X2 is an earpiece that's not quite so delicate as most, called the first water resistant and weatherproof Bluetooth headset by its manufacturer. This means if you get caught in a rainstorm it won't be ruined, but you probably won't want to do any underwater basketweaving while wearing it. The X2 is also said to be shock resistant, so it can probably withstand the pounding of a vigorous run, but all bets are off if you happen to be wearing it while totaling that Ferrari Enzo. Offering 14 hours of talk time and able to stand by for three weeks, it weighs just a half an ounce. Available in early March for $94.
