This quote might be a result of comparison between his beyers, which have pads that fit around the ear, versus grados, which have pads that rest on the ear. but folks should not think that they act like earmuffs, where pressure keeps the can on. just bend the band back until you don't feel pressure on your ears. some folks never get used to the feel of pads resting right on their ear, and consider it "clamping." well, my friend's HD280 has pads that go around the ear ("circumaural") and that thing clamps like a crab claw. it's not pressure on the ears, it's my head in a vise.
Bend the headband a bit, and viola. You can have them just rest on your ears if you want. The beyer dt880s (for comparison) I had had very little clamping force. They often moved around, and fell off my head. (I dance like a jackass when listening to music)
