So far I've used these to mix some guitar tracks and I will say these are pretty flat headphones to ally speaking which is great.  They aren't super comfortable but they are not uncomfortable.  You almost forget they're are there which is a good thing.  The only reason I didn't give these five stars is because of the feel.  The price was right for what I needed and I'm very happy.  I haven't used them for causal listening but that's not really what I bought them for.  I have some LSTN headphones that I really like for leisure music listening but those are too scewed towards lower frequencies to reliably mix anything even when doing a rough mix.
