Turtle Beach X41

Hey guys,

I want to buy a headset for my XBOX 360 and the Turtle Beach X41 is one of my favourite because the price is very good and it's wireless.

I read that a contra point is that you have to put batteries in. Interesting for me is the lifetime of those batteries?

Does anybody has experiences with this headset and can give me some more infos or do you have any other suggestions?
