"Once they are in there". Which is why you can make things work with headphones plus head motion tracking. When using speakers, the sound has to get 'in there' first. And you are allowed to turn and otherwise move your head, so even when e.g. seated you can (and will) explore the sound field around it, and your brain will correlate your movements with the changes of the sound entering your ears. So getting the right sound 'in there' is not just a matter of recreating the sound field at the two points where your ear canals would be if your head were clamped into a vise. You have to create something matching the field of a real source at least in the near vicinity. And it turns out you can't do that without energy arriving from more or less the right direction.
