I agree 100% since owning the LCD-2's and being tortured by the headband, the comfort of a headphone is now near the top of the list. I had resorted to placing some soft foam between the headband and my skull to be able to listen to them for more than an hour. The weight of the headphone never bothered me, but it seemed like the headband contacted my skull exactly in one of those stitched creases where there is 0 padding at all.
I will say the vegan pads and headband were super plush and comfy, but I'm not sure how they hold up long term.
That's a fear of mine, I've wanted to go Audeze for awhile now but because I wear headphones for such long periods (and am used to such comfortable headphones), I don't know if I'll be able to stand them comfort-wise for long.
