Short answer: the JBL Charge 4 on measured sound quality, the Ultimate Ears Wonderboom 2 on price. The JBL Charge 4 ranks #50 of 136 medium speakers at $119.95. The Ultimate Ears Wonderboom 2 ranks #86 at $80, $39.95 cheaper.
What the JBL Charge 4 offers: Doubles as a power bank for charging phones/tablets. IPX7 rated and floats. ~20 hour battery life; wirelessly links with 100+ JBL Connect+ speakers. Watch for: Not stereo. 1 Oval driver. Boosted bass, top a little rolled off, warm sound. Not as loud as a Charge 3.
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: 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.
Buy the JBL Charge 4 when sound quality outweighs the price for you, and the Ultimate Ears Wonderboom 2 when the price outweighs sound quality instead.
Battery life favors the JBL Charge 4: rated for 20 hours against 12 hours for the Ultimate Ears Wonderboom 2.
