Hi everyone! I'm new on here & looking forward to everyones expertise on this matter I have. I have a POD HD500X. I need to use headphones on it but the only ones I have are bluetooth. Instead of buying a new pair with fixed cable attached, I got a transmitter to plug directly into the phone jack behind the pod, then pared up both transmitter to bluetooth headphones. I can hear a bit of crackling in the headphones when I unplug & plug back in the transmitter but no guitar. Yes I checked all of the volumes, cables, blah, blah, blah but nothing. I'm stumped here guys & I need help! Thanx Bryan
