Sadly, there was a fairly substantial gap between the pads and the area between my cheekbones and temples (my face has a pretty big indentation there)... roughly 1/4 cm. With this, I'd consider them semi-open.
Forgot to mention that I wear glasses and I can't detect any difference in low end with and without glasses on. My glass frame are pretty flat and thin though - about 3mm thick.
FYI, that's not really me in my avatar...
