I received GREQ's custom headband leather strap yesterday. Initially I thought he made the strap too long to form around my head, but after some finickying around, I was able to get it to wrap perfectly around the contours of my head, by keeping the Ebay headband clip-on straps on as well, and now the comfort level is out of control.
I literally cannot feel any pressure on my head now whilst wearing HE500, even if I try. The only pressure I feel is just the slight clamp of the earpads, and the slight weight of the headphones on my neck/shoulders.
Interesting impressions with both the comfy strap and the padded headband together...comfort is phenomenal with just the strap itself, so this must feel really nice! I need to remake mine with slightly thicker/wider leather, but I couldn't be more pleased with this design!
