The weight of heavier headphones causes the grooves of the stand to dig into the headband. It doesnt affect functionality, but it'll affect the asthetics and resale value of some headphones.
When I first got the M-100's, I left them on the stand overnight; only to find that it had dug into the padding a bit(35 days later, those marks were still there). I'd rather leave my T1 and LCD-2 sprawled over my desk before placing them on that fangled contraption
