The clamp will disappear over time as it is similar to other Beyers in that aspect, I have big ears but the comfort was fine for me. And yes, I would classify them as a little bit bass-light even if it was run from a C.E.C. HD53N which is on the warm side afaik but it's nothing wrong really. I will probably listen to that demo pair at a later time to see how much it changes. What I really liked is how 'right' the high notes sound.
