Looking for a good 5.1 or 7.1 headset.

[35g700]

I'm in the market for a 5.1 or 7.1 surround sound headset. I need it to work with my Xbox 360, and my PC, so it will need to have an optical input and I have no idea what to get.

All suggestions are welcome

Thanks.

Edit: Any ideas on how good this headset is? http://www.newegg.com/Product/Product.aspx?Item=N82E16826235008
