Short answer: the JBL Partybox Stage 320. It ranks #3 of 51 party speakers by sound quality, rated 4.6/5, at $499.95; the Soundboks Mix ranks #34, rated 3.2/5, and costs $799, so there is not much of a tradeoff to weigh.
The PartyBox Stage 320 is the better-sounding, more featured party speaker. Two 6.5-inch woofers and two tweeters on 240W keep more bass at high volume than the PartyBox 310, and it adds a 5-band EQ, a karaoke mic input with echo, lighting and Auracast. Its removable battery is rated for 18 hours, and wheels and a handle move its 36.4 lbs (16.5 kg). It gets slightly sibilant at full blast.
The Soundboks Mix is lighter and tougher, with a much longer battery. At 21.4 lbs (9.7 kg) it is rated IP65 and claims 40 hours at mid volume from a swappable battery that fast-charges over USB-C. TeamUp links it with up to five other Soundboks. Its single 10-inch woofer does not dig as deep, its treble can sound bright, and it has no app, EQ or mic input.
Buy the JBL Partybox Stage 320. It is rated higher for sound quality than the Soundboks Mix and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
