on-ear headphones don't bother me too much as long as the clamping force doesn't go overboard. As long as the backs of my ears aren't pressed against my head and the pads are soft and breath a little bit (and aren't that cheap synthetic vinyl stuff) I can jam an on ear headphones.I've got small-ish ears, so maybe I'll get these to work as over-ears
But ya, I'm hoping my ears are small enough to fit inside the cups of the Vento
