Living in New York City I wanted a blutooth headset that would seal out all the noise while walking in the streets. The plantronics Discovery headset I thought would do the trick since it fits directly in your ear canal, unfortunately after trying each of thge 3 fitted ear tips provided I always had the same problem, "THE HEADSET WOULD ALWAYS FALL OUT" . I tried attaching the supplied ear hook but that was so uncomfortable that i decided to return the headset and try something else.
