Short answer: the Ultimate Ears Boom 4, if you are buying new. The Tribit Maxsound Plus ranks higher than it (#22 vs #103 of 157 medium speakers, 4.1/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Boom 4 is still sold new at $149.99.
The Tribit Maxsound Plus is the better-sounding, longer-running pick. Use XBass mode for flattest frequency response and balanced audio reproduction. It is rated for 20 hours of battery against 15 for the Ultimate Ears Boom 4. It keeps a wired aux input, which the Ultimate Ears Boom 4 lacks. The tradeoff: Slightly less deep bass than modern class leaders.
What the Ultimate Ears Boom 4 does well: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. It has an adjustable EQ, which the Tribit Maxsound Plus lacks. It charges over USB-C rather than Micro USB. Watch for: Not much improvement over the old ones.
Buy the Ultimate Ears Boom 4, since the Tribit Maxsound Plus is discontinued and only worth hunting down used.
