I dont know what headphones to get?

ive been looking at turtle beaches, which ive heard were the best for gaming, but im open to other brands as long as they are great. i want huge headphones like massive size but also clear and crisp sound so that even at the highest volume it doesnt distort or start to break and croak. i also want 5.1-7.1 and of course a really great mic so others can hear me great. this is all for PC too i also wouldnt mind if its either usb or jack i have like an 80 dollar limit so i was looking at the x21s or the tournaments from turtle beach
