Short answer: the JBL Boombox 2. It ranks #29 of 73 boombox speakers by sound quality at $350; the Sony ULT Field 7 ranks #40 and costs $400, so there is not much of a tradeoff to weigh.
On the JBL Boombox 2 side: 24 hour battery life (default volume); 20+ hours even at 60% volume. Set against that: Somewhat bass heavy and boomy.
The case for the Sony ULT Field 7: Better sounding than the XG500. The tradeoff: Still not as deep bass as the top ranked speakers.
Buy the JBL Boombox 2. It ranks higher for sound quality than the Sony ULT Field 7 and costs less, so there is no real case for the other one.
