To enhance the experience for Nothing users, when the Nothing headphone (1) is paired with a Nothing phone, the “Button” function gains an additional feature – audio source switching, making it easier to quickly switch and play your favorite audio content. The specific behavior is as follows:
On Nothing OS devices:
Short press: Switch audio source
Long press: Activate Smart Assistant
On other Android/iOS devices:
Short press: No function (audio source switching is not supported on third-party devices)
Long press: Activate Smart Assistant
Note: The audio source switching function is only available when paired with a device running Nothing OS.
