Personally I avoid wearing a bluetooth headset at all costs because they look lame. Everyone has "that" friend, you know, the one that wears their bluetooth headset all the time. Yep, it is fully dorky. Enough ranting about why I won't wear a bluetooth headset, and on with a bit about one of the cooler bluetooth headsets, the Sound ID 510.
the Sound ID 510 Bluetooth Headset is the first to have its own iPhone app, EarPrint, that allows you to tune the sound and monitor battery life. Check out some screenshots and video of the coolest (?) iPhone bluetooth headset after the break.
