JBL Charge 3 vs Ultimate Ears Boom 3

Last updated: August 28, 2026

Short answer: the JBL Charge 3. It ranks #67 of 136 medium speakers by sound quality at $80; the Ultimate Ears Boom 3 ranks #89 and costs $129.90, so there is not much of a tradeoff to weigh.

What the JBL Charge 3 offers: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. IPX7 rated; built-in noise/echo-cancelling speakerphone. Watch for: Less clarity than the Flip 4. Battery failures are common.

What the Ultimate Ears Boom 3 offers: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp Watch for: Not stereo, barely any bass, recessed treble. 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 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.

Buy the JBL Charge 3. It ranks higher for sound quality than the Ultimate Ears Boom 3 and costs less, so there is no real case for the other one.
