Halo 2 has "game specific" settings that will affect the chat functionality 
of the Turtle Beach X2.  

Original XBOX:  
    There are three main areas that need to be checked in order to make sure
    that the X2 will allow the user to hear all chat.

    1) Xbox Menu
       Without a game in the Xbox, the Xbox Menu will appear on the screen.  
       Select "Xbox Live" and select your user account, and then choose 
       "Voice Chat", press the (Y) button and select "Voice Through Speakers" 
       by pressing the (A) button. 

       (NOTE: If "Voice Through Headset" appears on the Voice Chat selection 
              screen, then this indicates that the setting is already correct)

    2) Halo 2 Player Settings
       When Halo 2 is launched, the audio options must be properly set for 
       the player profile.  After logging in, at the main screen, choose
       "Settings", then "Player Profiles" > "[choose your profile name]" > 
       "Edit" > "Voice Output". Select "Speakers Only", and then press (A). 
       Once this option has been set, it should be retained in your player 
       profile so that you will not have to set it again.  

       (NOTE: The same options can be set once the game has started by
              pressing the START button.)

    3) Xbox Live "Friend Menu" Settings
       If options (1) and (2) above are properly set, then most likely no 
       further options will have to be set.  However, if voice chat is not 
       heard and the previous options are properly set, then check the
       friends' List menu.  After signing into Xbox Live, the (Y) button can
       be pressed at any time to access the Friends' List.  Once this menu is
       open, press (X) to access additional options, select "Voice Output"
       from the menu, and then choose "Speakers Only" by pressing (A).


Xbox 360:

    1) Xbox 360 Dashboard
       When at the Xbox 360 Dashboard, after logging into your user profile,
       press the Xbox Guide button (the large "X" button  in the center of 
       your controller) to access your Xbox Live Settings.  Navigate to the 
       "Personal Settings" selection, and press the (A) button on your 
       controller.  Select "Voice" from the following menu, and press "A".
       On the Voice screen, make sure that "Play Through Both" is selected for
       Voice Output selection.

    2) The in-game settings for Halo are the same as described in Step (2)
       under Original Xbox (above).
