Short answer: the Electrotec Stage One for better sound quality, the Soundboks 4 for the lower price. The Electrotec Stage One ranks #10 of 46 party speakers at $1450. The Soundboks 4 ranks #24 at $1199, $251 cheaper.
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 trails the top Partyboxes on neutrality and bass.
On the Electrotec Stage One side: A genuinely balanced sound plus a dual swappable battery good for 100+ hours of total runtime. The tradeoff: it costs $450 more, and is tuned for loudness over deep bass too.
Buy the Soundboks 4 if the price matters more than sound quality. Buy the Electrotec Stage One if sound quality matters more than the price.
