Query: complaints of audibility

I love the lanyard and the earpiece (even though it looks kinda dorky w/ the flashing Motorola logo facing out), but (1) my phone (also a motorola) doesn't automatically detect it when it's on [maybe I'm doing something wrong, but if I am there are no instructions as to how to do it right]; (2) my friends often complain that they can't hear me very well when I'm using this bluetooth device .... so I end up not using it very much! Boo hoo
