Short answer: the JBL Pulse 5. It ranks #48 of 175 medium speakers by sound quality, rated 3.7/5, at $219.99. The Ultimate Ears Boom 4 ranks #113, rated 2.9/5, at $129.99, $90 cheaper, which does not close the gap in sound quality.
The JBL Pulse 5 is the better-sounding choice. A cool light show, though it is not synced to the music like the Pulse 2. The catch: Bass does not reach as deep as others, and the plastic scratches easily.
The Ultimate Ears Boom 4 is the lighter option. IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. At 1.4 lbs (620 g) it weighs much less than the JBL Pulse 5 at 3.3 lbs (1.5 kg). It plays in stereo from a single unit, unlike the JBL Pulse 5. The catch: Not much improvement over the old ones.
Buy the JBL Pulse 5. It is rated higher for sound quality, and the $90 you would save on the Ultimate Ears Boom 4 does not close the gap.
