I have some ray bans with thin metal frames. They don't cause any trouble with the david clarke headset. Flown 40 hours this month with no headache.
I'd second that.
Used to do Oakleys with some cheapish headsets and was in pain within 15mins. Now using some thin metal raybands with dave clarkes and is much better. Still if i'm flying for 2-3 hours it starts to ache a bit but much better than before. It will do me until i can afford some Bose x.
