Configuring Wireless Headphones with Mic

https://bbs.archlinux.org – I recently purchased the Sennheiser MM400 wireless headphones. With gnome3 they easily pair by using the gnome-bluetooth applet.Unfortunately they give stereo quality only on the A2DP profile, on which the Mic doesn't work. But if I select the HSP/HFP profile, the mic works but the sound quality gets deteriorated. Is there some way I can use the Mic on the A2DP profile. I have been unable to locate the bluetooth config files which gnome-bluetooth applet uses so as to try and tweak them. In case Mic support is not possible on A2DP, can I make change the current profile using a bash script (HowTos)
