Headphones

I'm thinking of buying my first headphones/headset and need some advice on what to buy and what to look out for.

I've watched Logan's videos on the audio myths and have watched reviews etc. etc. but I need some advice on what I sould get.

My preference would be a flat sound signature with not too much bass and clarity is my main aim. I would like them to be around/over ear and to not be too tight on my head as I have quite a large head. Also price has to keep down, I dont want to be spending a crazy amount as I will likely only play games and listen to music. (I'm no producer)

Any advice muchly appreciated thanks
