I know absolutely nothing about the model you picked out. However I would like to make the argument of "burn-in", I know my Beyers sound changed considerably after a good 40 or so hours of moderate levels of pink noise(just used the 9 or 10 hour clips from youtube). So keep in mind that the "sound" might change as the soft parts of the drivers loosen up and become more "even". Also psychoacoustics are quite real. If you listen to something long enough, you will actually train your ears to "hear" what you are listening to. Even bad speakers can sound "good" after a few years....lol... most changes are a bit more subtle though.
Basically, make sure he gives whatever he gets some time....he might learn to like them and they might eventually show him what he is missing once he gets a set of megabuck cans on his head...if that be the path he chooses. Maybe he's a lucky one and can get away from our electronic "addiction".... Good Luck either way....
