Great but sometimes unreliable
This headset can be great. It is clearly the clearest sounding headset for the xbox 360. Mine lasts for around 8 - 10 hours charge but i anticipate this is because i let it fully charge before i used it for the first time plus i charged it up every night. However, like other microsoft products, this can eb unreliable. I have had 4 but kept the recipts each time so i could return it but the device seems to have a habit of just not working at all. Every time mine has broke i have just finished using it, turned it off and then the next time i want to use it it does not responf whatsoever. Overall, a great mic with a clear sound (better than other microsoft microphones) but you need to keep your recipt because after a few months it may break totally for no reason.
