Best gaming headset for Xbox under $50?

I thought I found a deal on a Steelseries Siberia Neckband for $45, turns out it was the iPod version so I'm back in the market. I strongly prefer wired, the ones I'm considering are:

Turtle Beach x11 $35
Turtle Beach X12 $45
Tritton Trigger $40
Tritton Detonator $60

I can stretch a little for a step up in quality but a Tritton 720 or an Astro A40 is totally out of the question.

I really like my x11's. The powered subs in the headphones make all the difference. Even when i go to other people houses and they have the big dollar trittons and TB's i still like mine more. Even some of my friends agree.

I went ahead and bought the X12's for $40 plus a used Turtle Beach DSS 5.1 processor for $28. It really does help with being able to determine which direction a sound came from vs regular stereo. Doesn't necessarily sound better but it does the job.
