Ive bought my xm5's 1.5 year ago and I use them more than 10 hours a day.For the past few weeks my right earcup randomly starts sounding like ANC mics came loose and were swinging around. Sometimes it has a crackling noise and found out i could fix it temporarily by cleaning the built-up sweat inside the earcup.Does anyone have the same problem and is there any way to prevent this from happening?
