Of course I'm exaggerating (not as much as you would think) but the unit itself is very unusable in any nomad I've seen (including zen and jukebox), it crashes even more regularly than my karma, and the whole one tiny scroll wheel is about the dumbest idea anyone ever had. The software is really, really bad for nomads too. I would rather use a command prompt.
Also, AAC sounds quite good on the iPod. I can't speak to the equalizer because I don't generally do too many advanced equalizations. The SNR is a bit of an issue when I use an amp and Etymotics, but even then no mp3 player produces sound as good as a cd unless it's FLAC encoded.
Back on topic, the SR60's are very good. Maybe you can wear a hat to look less geeky. I would agree that the mx400/500's are not adequate in loud environments. Earphones that rest in the ear canal have their own set of problems too in some situations. It really depends on how he will use them.
