Hey J:
I ve had the J2 with the Mogul and now wirh the TP, the loud super noisy crackling hapened to me like twice and that was it. It only happened twice and I cant specualte who the culprit may be, Twice so far in between I dunno dude, J2 is the way to go still for me.
Plantronic 925 is being sold for 80 @ Costco just in case....
