All of my headphones have minimum padding and I'm not bald so my hair blocks me from feeling it that much.

I have the Sony MDR XD200 which have plastic head band and they get uncomfortable (and sometime painful) after about 30 mins. I'm not bald either but it's rather notice able. I also had the Sony PULSE headset which had a small amount of padding and I could wear those all day long and barely know they're there. It helps evenly distribute the weight across the top of your head reducing pressure points.
