Why not? Even if the Momentum's earpads come in contact with the ear, they are much lighter, the clamping force isnt as bad, and the leather earpads are more comfortable.
I just received my M-100s a week ago, and I am struggling to make them comfortable. The clamping force is like a vice grip on my head. I have managed to loosen it up a little bit by stretching out and twisting the headband 50+ times, as well as stretching them over a box for 4 consecutive nights. Still not good enough though. The earpads cause soreness and redness after about 15 minutes of use unless I adjust them constantly, however I think if i can reduce the clamping force, this will be less of a problem.
However, I read in one review that it takes up to 2 weeks to fully break in the M-100, so I'll stay patient until then.
