There is a lot of confusing information out there on the web. It is hard to judge what is current and what is outdated. Seems like there were a number of changes over the years. It looks like HFP is currently only supported by ofono while HSP is supported by both Looks like Pulseaudio is a big part of this. https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/ Bluetooth/ People seem to recommend JACKaudio for low latency audio http://wiki.linuxaudio.org/wiki/raspberrypi In other words I would have to access the headsets without PulseAudio. There is something called alsa_in/out which potentially takes care of this. http://jackaudio.org/faq/routing_alsa.html Best, Sebastian
