"With the updated controller, in addition to the volume and mute controls on gaming headsets, you'll also have the option to adjust headset volume, mic monitoring, and voice and game audio balance through the Settings menu on your console. We've also improved the quality of audio coming through the controller and increased the maximum audio volume on headsets used with this controller, based on fan feedback."
"In addition to audio improvements, we've fine-tuned the bumpers for more consistent performance anywhere along the full surface of the bumper. And we've enabled wireless firmware updates on the updated controller which eliminates having to connect the controller via USB cable to receive updates."
