Bose Soundlink Flex 2nd gen vs Marshall Emberton II

Last updated: August 28, 2026

Short answer: the Bose Soundlink Flex 2nd gen. It ranks #33 of 136 medium speakers by sound quality at $159; the Marshall Emberton II ranks #100 and costs $160.23, which makes this an easy call rather than a real tradeoff.

What the Bose Soundlink Flex 2nd gen offers: Pretty much identical sounding to the 1st gen Watch for: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail. Self drains the battery about 10% a week.

What the Marshall Emberton II 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.

Buy the Bose Soundlink Flex 2nd gen. It ranks higher for sound quality than the Marshall Emberton II and costs less, so there is no real case for the other one.

If battery life is a priority, the Marshall Emberton II is rated for 30 hours versus 12 hours for the Bose Soundlink Flex 2nd gen.
