The Two Speakers In Full
Marshall Emberton II: $144.99 Amazon eBay
Newer model: the Marshall Emberton III, ranked higher, rated 2.7/5.
Pros: 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. Measured bass extension of 62Hz (-10dB).
Cons: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud.

Ultimate Ears Megaboom 3: $111.63 Amazon eBay
Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5.
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life: about double most speakers this size. Measured bass extension of 70Hz (-10dB).
Cons: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
