I've been using Sennheiser HD 202 headphones at work for a couple years and finally got sick of their head-pinching discomfort. (I don't usually wear them for long periods, so it was only an occasional issue.)

I just received by Beyerdynamic DT 235 pair and am really enjoying them. Soft ear cups, less head squeeziness, airier treble (but not too much so) and more solid bass. Superior in every way.

I can explain it to you but I can't understand it for you.
