I still like the ESW9s a lot. No, they don't compare to better full-size headphones, but I wasn't expecting them to, nor have I made that claim. As far as good-sounding, portable, closed headphones go (a definite need for me), I'm loving these. If you're looking for what the best headphones can offer, these don't come close (especially in separation/air...things can be a bit thick), but then we're talking home headphones/systems. If you're looking for the best in portability (non-iem), I haven't found better. Amp choice does make a difference (I've been messing with an assortment), and I can no longer really recommend them unamped, though volume is no problem straight from an ipod. They also aren't the best with heavy rock, etc., but are wonderful with acoustic, small combo jazz and much of the music I listen to daily.
btw, I don't get the deal with the KSC-75. Sure, cost to performance ratio is maybe the best around, but outside of that and the plus of not caring if you lose them or they break, pffft.
