Short answer: the Ultimate Ears Wonderboom 2, unless you need the Megaboom 3’s drop rating and battery. The Wonderboom 2 is IP67 rated and floats for $80, well under the Megaboom 3’s $111.63, but it is not stereo with barely any bass and recessed treble. The Megaboom 3 matches the waterproofing and adds survival from drops of up to 1 meter, but it is not stereo and has barely any bass either.
Buy the Ultimate Ears Megaboom 3. It is rated higher for sound quality, and the $31.63 saving on the Ultimate Ears Wonderboom 2 is not enough to make up the difference.
Battery life favors the Ultimate Ears Megaboom 3: rated for 20 hours against 12 hours for the Ultimate Ears Wonderboom 2.

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.
