Sims/Logitech Collaboration (Winner Announced)

Do you have a larger head or an average/small one, @logion? I'm asking because I need a new headset but I have a really big head and most headsets range from uncomfortable to downright painful as a result.
It makes getting a new one a real chore, as I can't just order online, I have to find a way to fit-test them, or at the very least find someone else with a kinda big head to give them a rec.

Total aside, but i can't buy hats just off-the-shelf either, mostly even the largest size doesn't fit. I have to have my cowboy hats custom made. >.<
