Ever since I subscribed to Xbox Live, two and a half years ago, I've probaly broken five or six Xbox Live hedsets. the cheap fifteen dollar ones are so flimsy and breakable, It's totally worth buying one of the wireless hard plastic headsets.
If your a Halo fan, than the cool Spartan green color pattern is a plus. Theres no difference between the regular wireless headset and the halo 3 version except for the pattern, but they both work great. The sound is crystal clear and has an easy volume button on it.
The headset charges rather quickly and the thing that I like the most is the fact that it doesnt break easily. I've dropped it and even thrown it around a little and it still wrks fine. I would recommend buying one of thee rather than a regular headset because the regulr ones are cheap and flimsy.
