If you ever wire a loudspeaker channel the wrong way around, it feels very weird as a lot (but not all for a stereo mix) of the sound will cancel with the other channel in the middle of the speakers and you can move your head through this dead zone. I've never tried it with headphones, but I suppose even though destructive addition isn't going to happen it might affect things like intended spatial perception.
