The K240 are comfortable to you??
You must have tiny ears because those ear cups are shallow.
Yes, very, the first few weeks or month their comfort is meh, but after that they are very comfy, I can wear them all day with no issues, they only bother me when it's too warm inside. K240s with DT 880/990 pads is the most comfortable headphone I have ever worn, the pads ruin the sound though by making them a harsh and bassless mess. I find the Q701, K702 Annies, and K601 incredibly comfortable too, in fact I haven't worn an AKG that wasn't a 9 or 10 in comfort to me.
Actually my ears are big.
