Short answer: the JBL Flip Essential ranks #66 of 136 medium speakers by sound quality at $130; the Ultimate Ears Boom 3 ranks #89 at $129.90. With prices this close, go by the sound-quality ranking rather than the cost.
What the JBL Flip Essential offers: Aux input for wired sources. IPX7 rated. Genuinely portable at under a pound; a cheaper, more basic alternative to the Flip 5. Watch for: Less bass than a Flip 5.
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 Flip Essential if sound quality matters more than the price. Buy the Ultimate Ears Boom 3 if the price matters more than sound quality.
Battery life favors the Ultimate Ears Boom 3: rated for 15 hours against 10 hours for the JBL Flip Essential.
