When Microsoft released the Surface Headphones, they also released iOS, Android and Windows apps for managing settings and firmware of the audio device. The Surface Audio app was a little basic and now Microsoft have replaced the app with a combined Surface app. The Surface app has the management features of the Surface Audio app as well as information about your connect Surface devices. If you run the app on Surface device you get warranty information, pen pressure controls and other management controls.
In the video I look at the updated app on Windows and Android.
