Microsoft also promises that the firmware update will bring with it lower latency—this is part of the LC3 audio codec when compared to the old SBC audio codec—and improved battery life, although the company didn't say by how much. Finally the firmware will bring with it a preview of a broadcast audio feature that will allow "Windows 11 insiders on select PCs" to share the game audio with other Bluetooth devices, but the blog post doesn't go into any details of how this will work. The Xbox Wireless Headset will also be able to take advantage of super wideband stereo audio in Windows 11, which Microsoft claims will offer better in-game audio, although for those that already own a wireless headset with a dedicated dongle, this might not bring any real world advantages. To update the Xbox Wireless Headset you either need to use the Xbox Accessories app on an Xbox console or in Windows 11 and the update only applies to the 2024 version of the headset.
