Short answer: the Soundcore Motion 300. It ranks #2 of 136 medium speakers by sound quality at $79.99; the Marshall Emberton III ranks #99 and costs $165.04, so there is little reason to consider the other one.
What the Soundcore Motion 300 offers: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Watch for: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.
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 Soundcore Motion 300. It ranks higher for sound quality than the Marshall Emberton III and costs less, so there is no real case for the other one.
There is a real battery-life gap here: the Marshall Emberton III is rated for 32 hours, the Soundcore Motion 300 only 13 hours.
