I myself have Sennheiser HD600 and I love them for gaming/music/movies. Works amazingly for all of those. Clear and neutral sound with good sound stage and in my eyes affordable, don't know what your budget is as you don't mention it. And really comfortable to wear even for long periods. And if you happen to need mic at some point you can add Mod mic 4.0 by Antlion with them. I myself did a lot live comparison before buying my headphones and for my taste Sennheiser HD600 was best in under 400 price range. Sennheiser HD598 is good pair too if you want to save some money, but not as good as the HD600. Of course there are many good alternatives from other brands too, but Sennheiser got me.
