When I first bought my Wireless Headset, it was purely for the fact that I was tired to lugging around a controller when I wanted to talk via Live. However, as I continued to use it, I found myself enjoying it more and more.
The battery life is of a good length in general, and recharging is very simple. The sound quality is suberb, and the clarity of speech is improved upon from the original [wired] headset.
Additionally, the sleek look and simplistic design matches the 360 perfectly, and the product itself fits comfortably on the ear. I've found myself several times forgetting I was wearing it, and having a new sense of freedom while gaming on the 360.
A must buy for any hard-core/anti-wire 360 user.
