Audio Multitasking allows you to have an intercom conversation while simultaneously listening to music, FM radio, or GPS instructions. The overlaid audio is played in the background whenever there is an intercom conversation. If this feature is disabled, any incoming or outgoing intercom will interrupt your audio channel. You can enable Audio Multitasking through the Sena smartphone app.
