How large are their OTA headphones? I've been wondering about OTA noise-cancelling headphones for a while for both music and cycling as I've bad ears and excess wind leads to repeated otitis on short order (making actual non-stationary cycling problematic). But I also have large ears, so most OTA would literally sit on the ear cartilage and pressing it against the ear, making wearing them for extended periods very uncomfortable. I remember AKG cans having large-enough pads that they'd fit properly.
