Quote: I heard that they could keep up and what have you, but they look fairly small and seem to look like they are mostly for portable use. I was wondering if this was at all an issue with them or if they are just as good? Or if you have them, how do they compare to a full size headphone?

Sorry for adding to the 'which headphones should I buy' threads, but I've been reading around and looking at different headphones and I just can't decide on one.   So far I have read good things about the Shure SRH840 headphones, and the Sennheiser HD25-II's, and the Sennheiser HD595.  ...
