The following are differences between Xbox Controller S (available at retail) and Xbox Controller (available at retail, and packaged inside all Xbox Video Game Systems).

• Size/Comfort — Xbox Controller S is smaller. This design enables gamers with smaller hands a proper fit and is more comfortable for them during extended periods of play.
• Primary Button Placement — With Xbox Controller S, the new button placement is a more traditional cross layout. The four primary buttons are easier to reach, which is an important feature in certain games where quick button combination selection is necessary.
• Ease of Reach for Secondary Buttons — The black and white buttons are located below the primary buttons instead of at the top of the controller.
• Revised D-pad Surface — For improved directional movement, the surface of the D-pad has been modified into a cross pattern.
• Start/Back Buttons— These buttons are now located below the left thumbstick.
• Thumbstick Surfaces — The surfaces on the thumbsticks have been changed slightly, and an increase in surface area allows more thumb room.

Xbox Controller S is slightly different from the Japanese controller in the following ways:

• Cable Length — The length of the controller cable has increased from 2.5 meters to 3 meters.
• Updated Button Appearance — To more closely resemble Xbox Controller, the look of the primary buttons has been updated.
• Revised D-pad Surface— Minor improvements in the D-pad surface make it more comfortable for extended play.
• Revised Start/Back Button Height — To reduce inadvertent actuation of the buttons, the height of the start/back buttons has been lowered by a few millimeters.
• Stronger Springs in the Triggers — For better tactile feedback and a more intense gameplay experience, the springs in the triggers have been reinforced.
• Jewel Color—The green jewel has been replaced with a black Xbox jewel.
