i'd like to say one thing; because it what aaaalways needs to be said when these threads appear.
there is nothing inherently wrong with a headset being a "gaming" headset. the gaming tag does not make a headset automatically inferior to another.
now, two things to consider. first, headset which do have the gaming tag are, generally speaking, more expensive(for the level of quality they provide) than the equivalent semi-pro set. some cheap model are a total waste of money. but .. if you buy stuff like a $200 siberia, is it that bad, compared to a reference set? no, it isn't. sometimes the addon price you pay, for the microphone and "cool looks" is not even a bother.
second;
while semi-pro sets *do* offer better quality, and better sound at the price point, buying one is still not easy. people both wind up buying $400 sets that they don't need (diminishing returns), and some other times wind up buying (especially low-end) models where the brand name makes up 90% of the costs. yeah, because Sennheiser pulls the same SOAB stunts that Creativity does.
