Short answer: the Soundcore Motion 100. It ranks #39 of 136 medium speakers by sound quality at $47; the Marshall Emberton II ranks #100 and costs $160.23, which makes this an easy call rather than a real tradeoff.
What the Soundcore Motion 100 offers: Use Oluv’s EQ for the flattest response Watch for: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices.
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 Soundcore Motion 100. It ranks higher for sound quality than the Marshall Emberton II and costs less, which settles it without a real tradeoff to make.
If battery life is a priority, the Marshall Emberton II is rated for 30 hours versus 12 hours for the Soundcore Motion 100.
