Short answer: the JBL Partybox Stage 320. It ranks #3 of 53 party speakers by sound quality, rated 4.6/5, at $569.95. The Sony SRS-XV500 ranks #16, rated 4.0/5, at $315.99, $253.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The PartyBox Stage 320 is the bigger, better-sounding party speaker. Two 6.5-inch woofers and two tweeters on 240W keep more bass at high volume than the PartyBox 310, and it has a removable battery rated for 18 hours, a 5-band EQ, Auracast, a karaoke mic input and wheels. It gets slightly sibilant at full blast and weighs 36.4 lbs (16.5 kg).
The SRS-XV500 is lighter with a longer battery. At 24.7 lbs (11.2 kg) it claims 25 hours, with 2.5 hours from a 10-minute charge, and two 6.3mm inputs take a mic or guitar with key and echo controls. RTINGS found it warm and very loud, but its sound changes noticeably as you move to the sides and its bass pumps near full volume.
Buy the JBL Partybox Stage 320. It is rated higher for sound quality, and the $253.96 you would save on the Sony SRS-XV500 does not close the gap.
