Short answer: the JBL Charge 3. It ranks #67 of 136 medium speakers by sound quality at $80; the Marshall Emberton III ranks #99 and costs $165.04, which makes this an easy call rather than a real tradeoff.
What the JBL Charge 3 offers: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. IPX7 rated; built-in noise/echo-cancelling speakerphone. Watch for: Less clarity than the Flip 4. Battery failures are common.
What the Marshall Emberton III offers: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud. Not really any different from the Emberton II except having the treble turned down a little bit.
Buy the JBL Charge 3. It ranks higher for sound quality than the Marshall Emberton III and costs less, so there is no real case for the other one.
Battery life favors the Marshall Emberton III: rated for 32 hours against 20 hours for the JBL Charge 3.
