What Headset Should I Buy?

I've avoided throwing my hat into the ring because I wanted to see what other people thought.

I have the X41s. I love them to death. To me, they were worth the $200 they cost.
I used to use the X3's and when I made the switch from the analog audio to digital it was a remarkable difference in quality. Also, the 7.1 is VERY different from stereo. Yes, stereo will refer to multiple sources but 99% of the time when referring to audio equipment, if they're not explicitly saying more than 2, its 2. So 2 channel vs 7.1. I can sit still and be able to tell exactly which way an assassin is creeping up on me, or where the enemy is. Its not as useful for non-fps games, but its still an awesome feature.

Yes, there was a very slight (and I mean VERY) hissing noise at first but when the audio is playing, you'll never notice it. In fact, I use it to tell if my headset auto-shut off while i'm browsing Netflix and happen to be in the kitchen getting something to eat.

I haven't tried or experienced any other high-end headset on the market because for one, I don't have the money and none of my friends live in the area anymore, and two I really am happy with what I have. When I picked up the x3s to play and have audio overnight so my girlfriend wouldn't have to keep waking up from the home theater's blasting gunshots and explosives, I was thrilled with it. The x41's are a huge step up.
