Thanks for the pics and impressions. I would have thought that putting the Studio pads on the regular TMA-1s would increase clamp, since they are significantly bigger/thicker. The TMA-1s are already secure enough on my head, and the prospect of putting circumaural pads on them is just too intriguing. I wonder how the sound would change providing one were able to get a decent seal though.
Actually, looking at pictures of the pleather pads, those don't even look circumaural at all. They just look really large with a small opening in the center.
Yeah the clamping force is pretty weak. I found myself compressing the pads up against my head just to make sure what I was hearing. All the music I played sounded too far away from my ears. It's actually worse with the pleather pads.
