IMO the problem is not with the headrest at all but where the backrest meets the seat at the bottom. It's as if whatever is holding these two in place, BMW forgot to torque the two nuts and the whole thing rattles when there is nobody in the passenger seat. My solution to this is whenever the passenger seat is empty to put the seat at furthest point forward in the cabin and set this position as seat set up No.2. When I do this the rattling dissappears. Awkward I know, but a necessity.
Why not just tighten the nuts?
