Comment 39 for bug 405294

Another update on my previous post about bluez configuration. It turns out that the key thing here are the settings in hcid.conf:

lp rswitch,hold,sniff,park;
lm accept,master;

and audio.conf:

AutoConnect=false;

this one to prevent both a2dp and headset profiles connecting at the same time, when you turn it on.

Note that what I had previously set in audio.conf:
#Enable=Source,Control,Sink
#Disable=Headset,Gateway

is not a good idea. The 'Disable=Headset' removes the headset profile form the available services on the headphones altogether. i.e. you can't connect to 'headset' anymore. only a2dp.

Finally, if you want to have the headset profile work with pulseaudio (for e.g. skype), you need to use blueman, and make sure the bluetooth applet is enabled (in about -> plugins). The a2dp doesn't seem to need this, but the headset profile does.

Hope that made sense ...
