Soundcore Motion+ vs Marshall Emberton III

Last updated: August 28, 2026

Short answer: the Soundcore Motion+. It ranks #3 of 136 medium speakers by sound quality at $79.99; the Marshall Emberton III ranks #99 and costs $165.04, which makes this an easy call rather than a real tradeoff.

What the Soundcore Motion+ offers: The previous best sounding in class, still a great speaker with separate tweeters, more bass at full volume and better off-axis treble frequency response than the Uboom L. Just okay with the default EQ, I highly recommend using this EQ setting from r/kai7895 to get it more neutral. To achieve the absolute best sound you’ll need the Wavelet app (Android only) and set the provided Wavelet EQ in there too. Turn off the wavelet EQ for outdoor use. An alternative is Oluv’s EQ which only needs the Soundcore app EQ. Watch for: Not quite as neutral or detailed as the Uboom L. Without the above EQ, this speaker will rank around #25 in the rankings.

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+. It ranks higher for sound quality than the Marshall Emberton III and costs less, so there is no real case for the other one.

Battery life favors the Marshall Emberton III: rated for 32 hours against 12 hours for the Soundcore Motion+.
