Binaural recordings are indeed intended for headphones only; they do not reproduce properly through loudspeakers.
Binaural recordings are made with a technology that much more closely simulates the spatial imaging of natural hearing, when compared to conventional recordings.
The recordings are made with microphones placed on either side of a physical model of a human head. The mics are placed in the "ears" of the model. Because the mics are separated by the physical mass of the "head" on which they are mounted, the results simulate very closely the placement of actual human ears, which of course are separated and isolated from one another by an actual human head.
There are many good examples of binaural recordings floating around here at Head-fi. Probably the most dramatic is a skit, involving music and conversation, that simulates a visit to a barber shop. Sounds are vividly placed in space, with pinpoint locational accuracy.
