The K240 MKII have a pretty comfortable design. They're quite lightweight for their size and they're not too tight on the the head. Also the ear cups are sufficiently well padded that they won't cause any soreness during long listening sessions. However, the circular shape and size of the ear cups do not always fit well around larger ears. Also, the lack of padding on the headband slightly decreases their comfort level but isn't particularly noticeable once you have the headphones on.
