I've been using almost exclusively my S8F's for almost two years now and am very happy I bought them. They were a massive upgrade from the Shure SE535 I had been using for a few years prior, though I should also consider the fact that I upgraded to a Cowon Plenue R. Nevertheless, whether I'm listening to Jazz, Ambient, or Hip-Hop, these headphones give an enormous space and pick up the most unique characteristics of the recording for a beautiful blend. They are more than comfortable enough to keep in for more than two hours at a time.
Minor Issues:
The cable may be a bit of the heavy side
The cable's plastic seal is probably going to split like mine did just the other day after quite a lot of use
