Short answer: the Harman Kardon Onyx Studio 7. It ranks #12 of 73 boombox speakers by sound quality at $298.90; the JBL Boombox 2 ranks #29 and costs $350, so there is not much of a tradeoff to weigh.
What the Harman Kardon Onyx Studio 7 gets right: Warm sound with boosted bass. Set against that: Sounds a little sterile. 8 hour battery at medium volume, teeny bit less bass than the Onyx 6.
On the JBL Boombox 2 side: 24 hour battery life (default volume); 20+ hours even at 60% volume. IPX7 rated. The catch: Somewhat bass heavy and boomy.
Buy the Harman Kardon Onyx Studio 7. It ranks higher for sound quality than the JBL Boombox 2 and costs less, so there is no real case for the other one.
If battery life is a priority, the JBL Boombox 2 is rated for 24 hours versus 8 hours for the Harman Kardon Onyx Studio 7.
If water resistance matters to you, the JBL Boombox 2 at IPX7 (brief submersion) holds up far better than the Harman Kardon Onyx Studio 7 at no water resistance.
