These sit in different size classes, so this is not a straight ranking comparison. The JBL Xtreme 3 ranks #18 of 82 large speakers by sound quality at $329.95; the Marshall Emberton III ranks #104 of 144 medium speakers by sound quality at $160.03.
What the JBL Xtreme 3 does well: Better treble and deeper bass than the Xtreme 2. The tradeoff: Boosted bass.
What the Marshall Emberton III does well: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the JBL Xtreme 3 at $329.95 for a large speaker, or the Marshall Emberton III at $160.03 for a medium speaker instead.
There is a real battery-life gap here: the Marshall Emberton III is rated for 32 hours, the JBL Xtreme 3 only 15 hours.

Marshall Emberton III: $160.03 Amazon eBay
Older model: the Marshall Emberton II (rated 2.7/5).
Pros: 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. Measured bass extension of 62Hz (-10dB).
Cons: 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.
