Xbox one controller and headset disconnecting.

Turn off and disconnect all controllers from the Xbox 360 and disconnect the wireless headsets from the controllers.

Connect the wireless headset to the Xbox 360 using the USB cable. Turn on the wireless headset.

Sync the headset to quadrant 1 by pressing the "Connect" button on the on the Xbox 360. Then press the "Connect" button on the wireless headset for two seconds. Do not continue to press the "Connect" button on the wireless headset, as this will change the
quadrant to which it is connected. If the headset now works without the controllers attached, the problem must be with one of your controllers. If the headset still does not work, then the problem is with the headset.

1. Examine the headset, the cord, and the connector for visible defects.
2. Make sure that no dirt or debris is on the headset connector. To clean the connector, use a cotton swab dipped in rubbing alcohol.
3. Verify that your Xbox One controller operates correctly, and that you can use the controller to turn on and turn off the console. For help troubleshooting Xbox One controller issues, see Xbox
   One Wireless Controller disconnects or can't connect.
4. Firmly insert the Xbox One Chat Headset connector into the expansion port under the directional pad (D-pad) and the right stick on the controller

Try the following:

• Turn the volume down on your TV or stereo.
• Disconnect the headset, and then reconnect it firmly to the controller's expansion port.
  
  Note Never pull on the headset cable when removing it from your controller. Remove your headset from your controller by pulling on the body of the headset plug.
  
• Clean the plug on the headset cable with a clean cloth, and then reconnect the headset to the controller.
  
• Test the headset by connecting it to a different controller.
• If you're using an Xbox One Wireless Controller, replace the AA batteries or recharge the Xbox One rechargeable battery.
  

I'm having the same problem using the chat headset that came with it. I was playing Advanced Warfare and the controller disconnected. Would not turn back on even with new batteries. Finally disconnected headset and it came on. Tried plugging in via usb.
Works without headset. As soon as I plug the headset the controller turns off and will not turn back on. Have tried resetting xbox one, unplugging it and updated the firmware in the controller. None of it fixed the problem.
