I have a kind of fat head compared to others, and the most comfortable headsets I've found are the SteelSeries Arctis 3 or 5 (I've got both, they have the same shape, only difference I can notice is the Arctis 5 has RGB lighting on it). I have a hard time imagining not using them.
They're pretty sturdy too, I've had the Arctis 5 for about 3 years now and it still works perfect, no noticeable wear and tear.
I found them by going to Best Buy and trying on the headphones they had on display there. All the other ones they had were a bit uncomfortable, but these stood out as being really comfortable. You can also get them on Amazon.
Not the only person who thinks that, here's an excerpt from a review on Amazon:
"I've also tried many of Arctis' other headsets, including the newer ones and none of them fit like this one does. I have a big head and all the newer versions of their headsets are too small, or put pressure in the wrong spots on my head, or the ear cuffs are too small and don't fit my ears."
And this is from another review:
"The Steelseries Arctis 5 is the first Steelseries headset that’s fit perfectly on my giant head."[1]
