Short answer: the B&O A1 3rd gen for battery life, the JBL Xtreme 4 for a removable battery. The A1 3rd gen runs about 24 hours at sensible volumes at $379, while the Xtreme 4 lists at $309.95 with a battery you can remove. Both have catches: the B&O distorts easier than the 2nd gen with deeper bass, and the JBL is high priced.
Buy the B&O Beosound A1 3rd gen at $379 for a medium speaker, or the JBL Xtreme 4 at $309.95 for a large speaker instead.
