I upgraded from 1.2007.42-19 to 2.2007.51-3 and it does sound somewhat louder, not loud enough if I'm in a very noise environment, like on a bus perhaps and definitely not if I'm in New York City, but then again, you shouldn't been listening to stuff in NYC, with all the distractions, you need all your senses, so you are not hit by a car or something.
