How does volume sync work in PartyUp?

When your speakers first enter the party, the volume of each guest speaker will sync up to the volume of the host speaker.

If the volume of the host speaker is adjusted, the volume of all host speakers will also be adjusted.

The volume of each guest speaker can also be adjusted individually. If you want the volume of all speakers in the party to sync up again, you can tap the volume sync icon in the PartyUp screen of the app.
