No, they cancel out in front of your ears. If you imagine a bowl of water which has waves on it with a small buoy, then the noise cancelling is another wave emitter placed in front of the buoy that cancells out the Waves that are about to hit the buoy.
It's a very physical technology. The amazing/magical part of it is that the microphones pick up the Waves quickly enough for the headphones to emit the inverted wave.
