I own both (although I don't really use my Edition S much at the moment). The Edition S, imo, aren't anywhere close to the iSines for what you are wanting. Closed up, they lose a lot of what makes them sound good. Open, they sound very good (nothing absolutely spectacular, but very good nonetheless), but still not in iSine territory (again, imo). I would look elsewhere if you are wanting a good solid set of closed-backs.
I agree. I also have both and think the isine10 is much better. Plus, the isolation edition S is not that great compared to a true closed HP.
