Got my Fostex's from the previous drop, and after listening to their sound on a Grace Design m9XX, I'm glad I purchased them! They push a level of detail and imaging that I didn't think was possible from closed headphones. I plan on spending less time with my Sennheiser HD 580 and AKG K7XX in favor of these in the coming months. For anyone on the fence about purchasing these, go ahead and get them; easily money well spent.
