I have the 8100 and 8800 and looked into the S9 bluetooth stereo headset for music purposes. Per the Cingular website the S9 headset is supported by the pearl. Being that the headset is a stereo headset one would think that it will work for music purposes....or if they meant it works for phone calls only(which it does) they should have put it under all BT devices (ie. 8800) as being compatible.
