These are not really the same size class, and that is the honest framing here. The Bose SoundLink Max ranks #17 of 82 large speakers by sound quality at $399; the Marshall Emberton III ranks #104 of 144 medium speakers by sound quality at $160.03.
What the Bose SoundLink Max does well: IP67 rated - dustproof and waterproof to 1m. The catch: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange.
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 Bose SoundLink Max at $399 if you want a large speaker. Buy the Marshall Emberton III at $160.03 if you want 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 Max.

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.
