I'd like to mention that I doubt these will sound as good as the models they're... replacing?
Anyway, a major reason why the current phones sound as good as they do is down to how the driver's backwave is dampened by the material in the ear pads, BUT this set up is also what makes them so large and "leaky". These new phones are considerably smaller and seems to have been designed with portable use in mind, both of which makes it pretty clear that these don't have this system and thus will sound like every other closed can. The older phones bodies being made of wood also makes them much more resonant resistant than plastic.
Agreed, headphones have huge cups for a reason.
In terms of ascetics, these new cans are a mess of shapes, it's like someone vomited geons into reality. The Foster made units form these nice concentric circles and semicicles with the cup, then the wishbone, then the cantilever. The headband also follows this same even curve to round out the package.
Spot on, I'd also like to add on that the design style is very well done as well; it pretty much nails "modern masculine". Black leather, wood, matte metal, clean/sharp lines, and simple squares and circles. The only thing that doesn't really fit is the cantilever, which looks too round and alien to match the rest. I can sort of see where the designer was coming from with it (transitioning from circles to squares), but I don't think it was the best move. It seems they fixed that somewhat with the Fostex TH900.
