There was error connecting bluetooth headphones in Ubuntu (xfce) 16.04 : "Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol not available".

One of the solutions is installing bluetooth module for pulseaudio

or

pkill pulseaudio

3) Remove device from the list and try to pair it again.
