These have been around for a long time and they do work but there is a sharp sweet spot and no bass at all of course... and it's really only stereo for the one person they are focused on but if the 3d imaging of the original source is reasonable then the one listener will definitely hear the 3d imaging that one can hear with two regular loudspeakers when they are precisely in the originally prescribed sweet spot. Therefore, you can say that they technically do what they say they can do but that is less than regular a good stereo speaker pair. The main feature is that the ultrasonic beating that the two drivers do which produces the audible sound at the crosspoint is only audible for the one listener exactly in the crosspoint and not audible to anyone else in the vicinity, which is a good trick when it is desired.
