I listen to music a lot on the phone with one earbud in. I keep a plantronics voyager pro headset on the other ear because I'm often in noisy environments or working with both hands. With my old HTC, it would use the bluetooth if it was paired and connected even if I had headphones plugged in. The fascinate overrides the bluetooth and decides to use whatever is plugged into the 1/8" jack. So every time I receive a phone call, I have to unplug my headphones. One can imagine how this gets old quickly, especially if outside and carrying things. Is there a way to disable this behavior?
