Short answer: the JBL Flip 7, if you are buying new. The JBL Flip 4 ranks higher than the Ultimate Ears Megaboom 4 (#83 vs #170 of 175 medium speakers) but is discontinued; its replacement, the JBL Flip 7, is rated 4.2/5 at $89.95 and is still sold new.
The JBL Flip 4 is the better-sounding, lighter option. At 1.1 lbs (510 g), JBL Flip 4 combines 2x 40mm fullrange with Bluetooth and aux. At 1.1 lbs (510 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It keeps a wired aux input, which the Ultimate Ears Megaboom 4 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 4. The tradeoff: Battery failures are common.
The Ultimate Ears Megaboom 4 is the longer-running pick. IP67 rated, floats, and finally uses USB-C charging. It is rated for 20 hours of battery against 12 for the JBL Flip 4. It has an adjustable EQ, which the JBL Flip 4 lacks. It charges over USB-C rather than Micro USB. Watch for: A lot of distortion at higher volumes.
Buy the JBL Flip 7, the replacement for the discontinued JBL Flip 4; it is rated higher for sound quality than the Ultimate Ears Megaboom 4.
