Short answer: the Tozo PA1. It ranks #57 of 150 medium speakers by sound quality, rated 3.5/5, at $39.99; the Marshall Emberton III ranks #110, rated 2.7/5, and costs $160.99, so there is little reason to consider the other one.
The case for the Tozo PA1: Tozo PA1 uses 67mm fullrange. Watch for: Bass is limited by its 52Hz specification.
Why pick the Marshall Emberton III: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Tozo PA1. It is rated higher for sound quality than the Marshall Emberton III and costs less, so only choose the other one for a particular feature it does better.

Marshall Emberton III: $160.99 Amazon eBay
Older model: the Marshall Emberton II (ranked lower, 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.
