The Mikros stays on my head and ears better than any other on-ear I have used.
My take exactly on the Onkyo's. The ear cups are certainly larger in diameter than any other on ear I have tried, but smaller than an over ear. I find them to be quite comfortable, but the clamping force is almost non-existent. I would tend to agree with H T T. For me, they generally seem to stay in place nicely, and provide a good seal, but since I don't really feel them, I keep fussing with the placement to be sure they haven't moved. Probably not much help. I do like the larger size of the ear cups...may contribute to the wider than usual sound stage and instrument separation that is missing from a lot of on ear models.
