Short answer: the JBL Partybox 330, and it is not close. It ranks #2 of 17 party speakers at $629.95; the Soundboks 4 ranks #10 and costs $1,199, $569.05 more.
The Soundboks 4’s real advantages are battery and raw loudness, not tone. It is tied for the loudest battery-powered speaker in this class, with its own removable 40-hour battery against 18 hours for the 330. But our notes describe it as less neutral and less deep in the bass than the top Partyboxes, including this one, despite the higher price.
Everything else splits down predictable lines: the Soundboks 4 carries an IP65 rating against the 330’s IPX4, and includes SKAA wireless. JBL’s daisy-chain via Auracast only pairs with other JBL speakers, while Soundboks TeamUp links up to five Soundboks units.
Buy the JBL Partybox 330 unless outright loudness or battery life is the deciding factor. It ranks higher for sound quality and costs less.
Buy the Soundboks 4 if you specifically need the 40-hour battery, the IP65 water resistance, or the extra headroom, and are willing to pay more for it.
