These sit in different size classes, so this is not a straight ranking comparison. The Bose SoundLink Plus ranks #25 of 82 large speakers by sound quality at $269; the Marshall Emberton III ranks #104 of 144 medium speakers by sound quality at $160.03.
What the Bose SoundLink Plus does well: IP67 rated, IP67 water/dustproof. The tradeoff: Boosted thuddy bass, but not as deep as the SoundLink Flex and you should probably just buy one of those instead if you want a Bose.
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. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Bose SoundLink Plus at $269 for a large speaker, or the Marshall Emberton III at $160.03 for a medium speaker instead.
If battery life is a priority, the Marshall Emberton III is rated for 32 hours versus 20 hours for the Bose SoundLink Plus.

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.
