What's the difference between anker soundcore partycast vs trance?

The only thing I found was the trance has a bigger custom passive radiator but would that make any difference?

Partycast is a pairing protocol.
Soundcore offers this Partycast and TWS (true stereo)

I don’t think there is a soundcore partycast speaker

It’s just the soundcore rave mini but let’s 100 speakers connect to it

If I was to choose I’d go for the trance :+1:
