So basically I was having the issue that when I paired my 2 partybox's they would get out of sync and the music wouldn't play at the same time anymore. Listening to both of these playing with a delay was terrible. After that I tried to look online but couldn't find for the update at all. Then I came across a guy who faced the same issue. He had contact with JBL before about this and shared me the resources. After upgrading to this newer firmware it fixed my problem!
