Which was a big security hole since that way evil users may eavesdrop
into other users voip calls, or even use the mic for surveillance
purposes. Due to that we generally consider audio devices to be part
of the seat the same ways a mouse, a keyboard or a screen is.
Also, I am still wondering how you manage to seat two people at the
same distance from the L and R speakers... I mean, the only way how
that could work is one sits on the others lap...
