im having the same problem and Im using the addict headset and i've never had this problem before on my district with FSA and SCS, i've been riding for about a week and its still not broken in, its actually getting worse and when I first got it, it was fine, i've came to the conclusion it might be that the headset was made for use with the addict ICS possibly? Either way im switching to my FSA to see if that works
