Whats the best gaming headset?

Hey all, what do you thinks the best gaming headset and why? Benn looking to buy a new one - any ideas?

Gamemodes? Really?

In case it get’s moved instead of deleted, I’m using Sennheiser HD555 and it’s in-the-head tech is really awesome, they are also light which means I can wear them whole day without fatigue. You could try cheaper HD515 cousin, it’s supposed to be similar.
