PartyUp is Ultimate Ears’ own multi-speaker feature, managed through the UE BOOM app across the BOOM, MEGABOOM, HYPERBOOM, EPICBOOM and EVERBOOM lines. The MINIROLL also uses PartyUp, built on Auracast underneath, but its broadcasts are private to other MINIROLLs rather than open to any Auracast speaker - so it’s grouped here with the rest of the UE family rather than on the general Auracast page. PartyUp is UE-only.
