Short answer: the JBL Partybox 330. It ranks #2 of 53 party speakers by sound quality, rated 4.6/5, at $629.95. The Sony SRS-XV500 ranks #16, rated 4.0/5, at $315.99, $313.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Partybox 330 is the better-sounding choice. A rolling party speaker with deep bass, a removable battery, a light show and inputs for mics and a guitar. The tradeoff: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
The Sony SRS-XV500 is the longer-running, lighter option. 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 330. At 24.7 lbs (11.2 kg) it weighs noticeably less than the JBL Partybox 330 at 37.7 lbs (17.1 kg). The tradeoff: RTINGS measured poor directivity, so the sound changes noticeably as you move off to the sides.
Buy the JBL Partybox 330. It is rated higher for sound quality, and the $313.96 saving on the Sony SRS-XV500 is not enough to make up the difference.
