These are not really the same size class, and that is the honest framing here. The Marshall Emberton III ranks #123 of 173 medium speakers by sound quality at $179.99; the Marshall Middleton II ranks #31 of 108 large speakers by sound quality at $329.99.
The Marshall Emberton III is the lighter option. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. At 1.5 lbs (673 g) it weighs much less than the Marshall Middleton II at 4 lbs (1.8 kg). The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The Marshall Middleton II is the deeper-bass option. A 4 lbs (1.8 kg) IP67 portable speaker with very deep bass for its size (38Hz at -10dB), a 30-hour rated battery and a power bank output. Its bass reaches about 38Hz before falling 10dB, against 62Hz for the Marshall Emberton III. It keeps a wired aux input, which the Marshall Emberton III lacks. The tradeoff: Bass boosted which drowns out the midrange.
Buy the Marshall Emberton III at $179.99 if you want a medium speaker. Buy the Marshall Middleton II at $329.99 if you want a large speaker instead.
