The Two Speakers In Full
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.

Pros: Small size.
