Short answer: the Klipsch Nashville. It ranks #85 of 175 medium speakers by sound quality, rated 3.3/5, at $84.80; the Ultimate Ears Boom 4 ranks #113, rated 2.9/5, and costs $129.99, which makes this an easy call rather than a real tradeoff.
The Klipsch Nashville is the better-sounding, longer-running pick. Sturdy rubber-coated build. ~24 hour battery life with fast 18W USB-C charging; can reverse-charge your phone. It is rated for 24 hours of battery against 15 for the Ultimate Ears Boom 4. The tradeoff: Upper bass boost.
The Ultimate Ears Boom 4 is the lighter choice. IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. At 1.4 lbs (620 g) it weighs noticeably less than the Klipsch Nashville at 2.1 lbs (970 g). It plays in stereo from a single unit, unlike the Klipsch Nashville. Watch for: Not much improvement over the old ones.
Buy the Klipsch Nashville. It is rated higher for sound quality than the Ultimate Ears Boom 4 and costs less, which makes it the one to get unless you need something the other one does better.
