The description says it comes with an AC wall adapter. If accurate, based on previous threads here, this may be an older version of the headset. It seems the newer version is the one that comes with a USB charging cable instead of the AC wall adapter. There's been speculation that the newer version may include "improvements" that MS said they made in the Halo version of the headset. It's possible this IS the USB charger version, and Buy.com just hasn't updated their description. Unfortunately, I can't find a part number listed in the description, which might clarify what you're getting.
