Short answer: the Wonderboom 2 is IP67 rated and floats, but the Charge 3 is the one with the power bank. The Wonderboom 2 is IP67 rated and floats, but it is not stereo, has barely any bass, and its treble is recessed. The Charge 3 doubles as a 6000mAh power bank for USB devices, though it has less clarity than the Flip 4.
Buy the Ultimate Ears Wonderboom 2 if you want one new; the JBL Charge 3 is discontinued, so only look for it used.

Ultimate Ears Wonderboom 2: $80 Amazon eBay
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.
