I have the 3D and voyager blutooth, here's the problem, everybody says they can't understand me,or have a hard time understanding me and the longer i talk the worse the noise gets, I pair with my wifes shift and clear as a bell and paired with my Hero clear also,so buy a pro + yesterday and same problem,the shift sounds clear as a bell, {Hero retired but will bring back online if need be}.A friend says its almost like its overmodulating and thought it could be his phone,but it sounds the same whether its his Motorola or iphone,any help here?
