What headset should I get for the xbox360. The Turtle Beach PX21, DPx21, Dx11.?

I have had and x11 and that ended up falling apart for me. So then I turned to the x31's, but it tears through AAA's too much for my taste. I don't want to have to waste my money on batteries every month. I have a bunch of gamestop gift cards and I wanted to give one of these headsets a try. I would prefer the ones with the dolby sound enhancer thing... watever its called
