When I wear my earbuds (Denon AHC360) I have a problem. When Im walking with them in (the cord in my shirt) the shirt tugs on the cord and I have to keep readjusting my earbuds. I think the cord falls back into my shirt, and that makes the shirt tug on it. (the cord on my earbuds is thin, if that is a important factor.) Is there any way to fix this? Thanks!
