Short answer: the Sonos Roam for better sound quality, the Marshall Emberton II for the lower price. The Sonos Roam ranks #75 of 142 medium speakers at $179.99. The Marshall Emberton II ranks #103 at $159.99, $20 cheaper.
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.
What the Sonos Roam offers: Very neutral. IP67 rated at ~1 lb. Wireless (Qi) charging - rare for a portable speaker. Works with Alexa/Sonos Voice Control and the wider Sonos ecosystem over Wi-Fi. Watch for: Bass extension isn’t very good. Not stereo. Gets distorted if you turn up the bass.
Buy the Marshall Emberton II when the price outweighs sound quality for you, and the Sonos Roam when sound quality outweighs the price instead.
There is a real battery-life gap here: the Marshall Emberton II is rated for 30 hours, the Sonos Roam only 10 hours.
