I see your avatar pic is AKG Q701 white(I guess by your avatar that you own a AKG Q701) and you listened to how many models, 50-100, and you are primely into gaming, right? So if it is the best posibble choice for you and you are fond of Dolby Headphone as I am too why would I look any further? From what I read I concluded that you cant really beat AKG Q701 for gaming and everything else I mean all around headphones. Just to add that I never listened anything else on PC except Beyerdynamic MMX 300 and my opinion is based on reading the forums, reviews on internet and so on...
Yes, the Q701s are MY favorite headphones out of the ones I've tried (see my profile), but that doesn't mean they will be YOUR favorite headphones
But they are my top recommendation.
