No idea what I'm doing

So I have a bit more money than I expected to have and have decided to spend this £200 on some new headphones / headset rather than upgrading my 780 to a 780ti. Well the title says it all I'm looking for a good pair of headphone or headset for around £200 or under. I already have a blue snowball for my mic and I listen to music quite a bit but wouldn't consider myself an audiophile. I'll be streaming with these so want  something that are comftable for long use but are also good for games. Just looking for suggestions on what sort of headset (make or model) I should look at.
