Sony's getting in on the pre-IFA action by announcing a revamp of its biggest party speakers, confirming that its Ult branding is very much how it sees the path forward for its audio business outside of the very biggest hitters (namely the WF and WH-1000XM series of headphones and earbuds).
The new speakers are all pretty big, but the biggest of them is frankly massive, so these are launches aimed very much at those putting on proper parties, raves, and events.
