Short answer: the JBL Charge 3 ranks #67 of 136 medium speakers by sound quality at $80; the Ultimate Ears Wonderboom ranks #87 at $79. Close enough in price that the sound-quality gap is the deciding factor.
The case for the JBL Charge 3: Doubles as a 6000mAh power bank for USB devices. The catch: Less clarity than the Flip 4.
On the Ultimate Ears Wonderboom side: IP67 rated and floats. Watch for: Not stereo, barely any bass, recessed treble.
One note: the JBL Charge 3 is discontinued, but it still ranks #67 of 136 medium speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL Charge 3 if sound quality matters more than the price. Buy the Ultimate Ears Wonderboom if the price matters more than sound quality.
If battery life is a priority, the JBL Charge 3 is rated for 20 hours versus 10 hours for the Ultimate Ears Wonderboom.
