I have a Bose series 2 Bluetooth headset that sounds fantastic while listening to music on my iPad and Kindle as well as my iPhone. For whatever reason it sounds horrible and muddy on my 920. Its a shame the eq doesn't function except for wired headsets. On the other side though I have a set of Moto Rokrs that sound good with the 920 but not very discrete at work. Any experiences with the Bose out there?
