I can just say a couple things.
One is that year ago - I'm guessing about 10 - I got the Plantronics GamePro 1 headset.
It's great. I can't compare it technically to others, but it's light to wear - I wear it many hours a day, never discomfort - and sound is 'perfectly fine gaming sound' with good directional sound.
I hear (no pun intended) nothing but good things about the mic quality.
They're in the 'I'd be happy to get there again, what else do I want' area, though it's always tempting to look for some amazing sound quality.
Unfortunately, they're also no longer made - the only ones I found in a quick online search were on Amazon for $140, instead of the 'normal' $50 price. I assume there's a replacement?
The lesson from them I guess is that the light, more open style seems to be great to use.
The second thing is that I bought the World of Warcraft headset for $100 or more. Immediately on putting it on, it was sort of heavy and bulky, not that comfortable - naturally things that only get worse, and after wearing them briefly it's a relief to take them off. Unfortunately, the sound quality doesn't do anything to justify the discomfort; and I had nothing but complaints about the mic.
So, they're a $100 loss, worn an hour or two, lesson being the bigger, bulkier headsets have that discomfort issue, and I should have tried to find a way to test them first.
I wouldn't underrate comfort in picking a gaming headset - make it a requirement. You don't need to feel annoyed every time you use them.
