hiya guys so i finally got myself a helmet camera today, a drift hd 1080 but already have a problem with it, while recording no matter how loud the situation all i can hear is  humming and buzzing etc on play back any idea how to fix this or is it a fault with the cam?  
should note its with the external mic as the mic i got doesnt fit lol, side question, anyone one know the jack size ill need for a mic?
