Short answer: the JBL Partybox 330, if you are buying new. The JBL Partybox 310 ranks higher than the Sony SRS-XV500 (#4 vs #16 of 54 party speakers) but is discontinued; its replacement, the JBL Partybox 330, is rated 4.6/5 at $629.95 and is still sold new.
The JBL Partybox 310 is the better-sounding choice. A top party speaker with remarkably deep bass and balanced sound, wheels and a handle, now discontinued but worth buying used. The catch: It is very large, at 688 x 326 x 368mm and 37.5 lbs (17 kg), so it is a poor fit for small spaces or carrying far.
The Sony SRS-XV500 is the longer-running, lighter choice. A slightly warm party speaker with plenty of bass punch that gets very loud outdoors, plus karaoke inputs and a long battery. It is rated for 25 hours of battery against 18 for the JBL Partybox 310. At 24.7 lbs (11.2 kg) it weighs noticeably less than the JBL Partybox 310 at 37.5 lbs (17 kg). The catch: RTINGS measured poor directivity, so the sound changes noticeably as you move off to the sides.
Buy the JBL Partybox 330, the replacement for the discontinued JBL Partybox 310; it is rated higher for sound quality than the Sony SRS-XV500.
