Sincerely, I was expecting for Microsoft to do something like these after all they done to gamers in the past months, including DRM, always-online policies. As you may know, Xbox One does not come with a headset included because the Kinect motion-sensor includes a microphone.
Well, considering Xbox One’s price tag, it’s odd that they don’t include a headset in the box, but as I said, it was expected. You can buy a the headset separately, Microsoft is yet to announce a price for it. If you don’t like the kind of business Microsoft practices with the headset, you can always buy a third-party one from several retailers.
