I just ordered a BT530 from ebay for $45. Looking forward to it. I am using a wired headset now and the wire is getting in the way a bit. Does the call button on the BT headsets discussed here work to pause / play music? Does it allow you to answer a call when listening to music such that it will pause the music while talking on the phone and then continue the music once the call is done? I am using a motorola droid, BTW.
