It's rather interesting and worth a bit of Googling later... the question of isolation vs active noise cancelling.
I remember seeing not all that long ago a show with a train air horn going up against a new kind of material that effectively absorbed sound waves and converted them to heat.
Wonder if those kinds of material would make sense in headphones.
