They are semi-closed. If you look at the pic you'll see that the black donut is the fake screen you see on the outside. It's actually a solid plastic like material. The center round screen you see from the outside is real. It is damped, but you can see through it and does let sound out. That makes it open... well the drivers have damping material also, so it's not exactly an open design, nor is there enough damping to make them closed.
I don't care for the internal design myself but these drivers have potential (hmm) to possibly sound pretty darn good in a different enclosure IMO. Sony seems to like to restrict bass, these enclosures assure that, also IMO.

j/k I can think of a couple of member that enjoy that combo.
