Short answer: the Ultimate Ears Wonderboom 2, since the original offers nothing it lacks, though neither ranks well in its class. Both are IP67 rated and float, and both are not stereo with barely any bass and recessed treble, so the newer speaker is the straightforward pick. The original does cost $79 against the Wonderboom 2’s $80, a gap of only $1 that buys the newer model. Both are rated below 3.0/5 among the 151 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
Buy the Ultimate Ears Wonderboom 2 if you want one new; the Ultimate Ears Wonderboom is discontinued, so only look for it used.

Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5.
Pros: IP67 rated and floats. Compact and light enough to toss in a bag. Measured bass extension of 82Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. Slightly boosted 93Hz upper bass Dip at 9kHz. 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 2019. Not technically a 360 speaker, only front and rear.
