Hari_SeldonI consider my head to be larger than average, baseball caps always fit weird, and I use these at my computer for hours on end. Everyones head is different but I think between the amount of adjust-ability and the way the ear cups are in a sort of rubber suspension they should fit almost anyone.
Hari_SeldonI'd say they should fit pretty well. I have to max out the headband on some of my Koss headphones, but with these I only have to extend the headband about 3/8" on each side.
