You're welcome! With the time I spent with the 1266, the comfort was honestly not AS BAD as I thought it was. For my head at least, I wouldn't use it for more than like 2 hours maxiumum before taking a breather for a few minutes. The Diana is leagues better in comfort and honestly, even in sound. I think it would fit most people's heads just fine. I think the diana also has an accessory that allows you to fit some padding on the headband though which is supposed to add more comfort and alleviate any hotspots there!
