I have a Verizon Curve 8330 and a Motorola H700 Bluetooth. FOr some reason I can't seem to be able to listen to music on my bluetooth, but I tried the same bluetooth on another phone and it worked fine.
from what i understand the headset must support a2dp bluetooth profile. usually thats a headset with two ear pieces. only mono headset i know that supports it is jabra bt8040 which i just ordered earlier today. with that, you will be able to hear music thru bluetooth headset
