My soundsport free wireless headphones are connected to my Mac. Within the sound preferences, my headphones are selected as the input device. This seems to mean that the headphones are currently in handset mode. The symptom of this is that no sound comes out of the left ear bud. I used to be able to fix this problem by manually changing the input sound device back to the Mac's internal microphone. Like magic, the balance controls reappeared on the sound output tab. (Otherwise, it will tell you that the device has no output controls).
Long story short, this doesn't seem to work any more. Is there another way to manipulate the bluetooth profile that these headphones use so we can put them back in "headphone" mode instead of handset?
