Does macOS have Audio Sharing?
macOS does not present the same simple AirPods Audio Sharing experience that exists on iPhone and iPad. Mac users can work around audio routing in a few ways, but SoundShare is designed around the shared-listening experience directly.
How SoundShare brings audio sharing to macOS
SoundShare lets you connect two AirPods or multiple Bluetooth headphones to one Mac and listen together. It works with the Mac audio you already use, whether the sound comes from Apple Music, Spotify, YouTube, Netflix, podcasts, or another media app.

iPhone Audio Sharing vs SoundShare on Mac
iPhone Audio Sharing is built into iOS for supported Apple headphones. SoundShare is for macOS users who want a similar practical result on Mac: one device playing audio, multiple people listening on their own Bluetooth headphones.
