Short answer: the Bogasing M5 on placement and price. It ranks #61 of 179 medium speakers at $52.99, against the Emberton II’s #127 of 179 at $151.99, and it is compact enough for a backpack side pocket at under 1.7 lbs (771 g). Both claim 30 hours; the Bogasing sounds thin in the midrange with hot treble and rolled off bass unless bass mode is on, while the Emberton II has an echo-like coloration and is not very loud.
In favor of the Marshall Emberton II: It offers 30 hours of battery life, among the best in its class, with a 20 minute quick charge adding 4 hours, plus an IP67 rated, durable rubbery build using 50% recycled plastic. The downside: it has a strange, unnatural echo-like sound coloration with bass that doesn’t go as deep as competitors, isn’t technically a 360 degree speaker since it only fires front and rear, and isn’t very loud.
Bogasing M5’s strengths: It’s compact enough for a backpack side pocket at under 1.7 lbs (771 g), offers up to 30 hours of battery life, and charges over USB-C with no proprietary cable to lose. The tradeoff: its front/rear driver configuration needs bass mode for the flattest response, and it sounds thin in the midrange with hot treble and rolled off bass in the default mode.
Buy the Bogasing M5. It is rated higher for sound quality than the Marshall Emberton II and costs less, so only choose the other one for a particular feature it does better.
