Short answer: the JBL Flip 4. It ranks #63 of 136 medium speakers by sound quality at $70; the Ultimate Ears Wonderboom 3 ranks #85 and costs $79.99, which makes this an easy call rather than a real tradeoff.
What the JBL Flip 4 offers: Less bass than a Flip 5. Peaky lower treble. Watch for: Battery failures are common.
What the Ultimate Ears Wonderboom 3 offers: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery - longer than the Wonderboom 2. Watch for: Not stereo, barely any bass. Boosted 93hz upper bass. Cuts bass heavily at high volume. 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 2022. Not technically a 360 speaker, only front and rear.
Buy the JBL Flip 4. It ranks higher for sound quality than the Ultimate Ears Wonderboom 3 and costs less, which settles it without a real tradeoff to make.
