The new XBOX ONE bundle doesn’t come with a headset. Even, you can’t use existing headsets. XBOX ONE-ers is very happy now, as they get a news that Microsoft team will be soon with a fix for the headsets.
“The Wireless Controller has been redesigned to allow for higher data transfer speed between the controller and the console. This also required creating a new expansion port design for headsets and future controller add-on devices which is different from a standard audio plug input. Xbox plans to develop solutions in the near future to allow consumers to connect many brands of wired gaming headsets to the Wireless Controller for gaming and chat audio.” – As told by a Microsoft Representative.
