Short answer: the Bose S1 Pro. It ranks #13 of 46 party speakers by sound quality at $699; the Soundboks 4 ranks #24 and costs $1199, so there is not much of a tradeoff to weigh.
What the Soundboks 4 gets right: Tied for the loudest battery-powered speaker, with a removable 40-hour battery. The catch: very large, not stereo, and behind the top Partyboxes on neutrality and bass.
On the Bose S1 Pro side: Extremely compact and light with crystal-clear audio and a real three-channel mixer. The tradeoff: full-range music starts to distort above about two-thirds volume - it’s built more for voice amplification than headline bass.
Buy the Bose S1 Pro. It ranks higher for sound quality than the Soundboks 4 and costs less, so there is no real case for the other one.

Bose S1 Pro: $699.00 Discontinued Amazon
Pros: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 mic/line + 1 line/Bluetooth). Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode. Up to 11 hours battery life. Professional build quality.
Cons: With full range music, it becomes distorted above ⅔ volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass. Discontinued.
