Yes, specially for the quieter parts (where the Signal-to-noise ratio is lower) I noticed considerable difference, at least for my urban environment. You can get away with lower sound pressure levels [volume].
Oh. I see. The problem is that they cause you to turn your volume up, lol. That's my favorite part of Pink Floyd's The Wall, most of the album is really quiet which lets it get REALLY LOUD on a couple occasions.
