Yes, cost. That little bit that can make something entirely not worth it. You can buy a top of the line headset like that Carcharias which lets you hear the game, talk to your team and doesn't hurt your ears for $70. And what you're missing is that this is what headsets are for. It is not the same market as headphones, headsets are not for listening. I suppose you could listen with them, I happen to use a seperate set of speakers for music and movies, but it's not the primary use. Perhaps by some miracle Unicorn or knuck will come by and help shed some light, but I'll try to explain. Headsets are targetted for people who game first, everything else second. It doesn't matter how rich your bass is or how crisp your mids are, as long as you can tell each sound from the other. It's much like graphics, low settings tell you everything you need to see. Anything else is at your discretion to buy a more powerful computer capable of running them at a reasonable frame rate. There may indeed be some people who want high quality sound and also put their games first. But, exactly as you say, it's going to cost. It's not a strictly superior option.
