Those actually do work with Linux.  It's the speakers Plumbers has
provided to BoF/Hack sessions that needed remote attendees.  There was
a pulseaudio issue a while ago that any Mic/Speaker combination that
exported HFP instead of HSP didn't work, but that's fixed upstream (but
you might need to upgrade your pulseaudio).
