I had another Motorola headset some time ago. I bought that one because of the folding mic. The idea I thought was really cool. That headset lasted a few months before it broke. It seems Motorola hasent improved on this design over the years. This was a fear prior to purchasing. The mic still works but it also serves as the on/off switch for the headset so quiet annoying to say the least! I could never verify the "300ft" range. With all that being said I will be returning my headset.  If you buy treat the foling mic as if it were made of very thin glass and you may be alright.
