Short answer: the Sony SRS-XE300. It ranks #92 of 136 medium speakers by sound quality at $137; the Marshall Emberton III ranks #99 and costs $165.04, so there is little reason to consider the other one.
What the Sony SRS-XE300 offers: IP67 rated. Orientation-aware playback switches to stereo when laid flat. Party Connect links up to 100 speakers; fast charging (10 min charge = ~70 min playback). Watch for: Muffled sounding, not very deep bass. Hollow sounding. Worse than a XB43
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 Sony SRS-XE300. It ranks higher for sound quality than the Marshall Emberton III and costs less, so the other one has nothing left to offer.
