I am also interested in opinions on this, I want to get a great $100> headset with surround sound. I was looking at the Z6a (or is it Z6i?) Turtle Beach.
I bought a new headset not so long ago. It was the SteelSeries Siberia v2. It's really good in my opinion. It was 80 € here, so i'm sure that it will be cheaper where you live.
