Ultimate Ears Megaboom 3: $163 Amazon
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size.
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.
