Audio Sharing
While it’s not a feature unique to the new AirPods Pro, the newest AirPods also take advantage of the new Audio Sharing capabilities introduced in iOS 13.1, allowing you to listen together with somebody else who is using any of Apple’s W1 or H1-equipped earphones or headphones. This not only includes older AirPods, but also any of Beats’ Powerbeats, Solo, or Studio wireless headphones.
Audio Sharing can be triggered by bringing up the normal playback destination controls, which now include a “Share Audio” option shown below your AirPods. Tap on this and then either bring a friends’ headphones or the iPhone or iPad they’re connected close to your iPhone, and Audio Sharing should just start working. It’s seamless and magical.
