So I just purchased the sony bluetooth headphone set (DR-BT10CX) and I have a Nokia N80 phone and a Sony NWZ-829 mp3 player. I've finally gotten the gist of it down so I can switch between my phone and the player. However I'm trying to figure out if there's a way to only get the player to pause and switch to the phone if I'm making a call or receiving a call. Because right now it switches over and stops my music if I do anything on the phone (texting or switching options) Does anyone know if there's a way or if this is just how it is. thank you, Moses
