The console is in good condition and everything works as expected. The rechargeable battery life is not as great as it was on day 1 but it still works well. The charging cable can be used to operate the controller as a wired controller instead of wireless. The headset was originally made to work with the xbox 360 but it works just as well with the xbox one. The extra TV hookup cable is not necessary (but is included anyways) to use with the xbox one and it only needs the USB cable to be plugged in through the USB port on the back of the console. The stereo adapter that plugs into the controller is what you use to plug the headset into the controller. The adapter is what is used to control the game/chat volume balance instead of the volume control on the headset (it is instead used as a master volume). The 48 hour Xbox Live code is unopened but I don't have verification if it is valid. I assume that since it hasn't been opened that it most likely is still valid.
