Maybe if the headsets became "ultra-comfortable", but these are nowhere near that. I have some much better than average headphones, that are near top of the line for comfort. They still are too much after a few hours.
I wore a pair of Sony MDR-7506, the ubiquitous radio cans, for 8+ hours every day while operating and editing talk radio and didn’t even notice, despite the job calling for constantly necking them and then putting them back. And I have a large head. They’re ubiquitous in radio for a reason.
