Holy crap most
Bluetooth headsets are awful to be seen in public with. Seriously, if you see someone wearing a Bluetooth headset who isn't on the phone, please smack them (for legal reasons I need to remind you not to batter or assault anyone!). Unfortunately, Bluetooth headsets are a necessity for many people. Either you need to drive while talking, or you just don't have enough free hands (I have four of them). So when you must use a headset, it should be one that offers a pain-free experience and doesn't look like you have a techno-parasite hanging off your ear.
