Short answer: the original Wonderboom on price, the Megaboom 3 only if you want its drop rating. Both are IP67 rated and float, and both are not stereo with barely any bass; the Wonderboom costs $79 against $111.63 but adds recessed treble to its flaw list. The Megaboom 3’s edge is that it survives drops from up to 1 meter, which the body does not claim for the Wonderboom.
Buy the Ultimate Ears Megaboom 3. It is rated higher for sound quality, and the Ultimate Ears Wonderboom is discontinued, so it is only available used.
There is a real battery-life gap here: the Ultimate Ears Megaboom 3 is rated for 20 hours, the Ultimate Ears Wonderboom only 10 hours.

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.
