Short answer: the Bose SoundLink Revolve (Series II), if you are buying new. The Bose Soundlink Revolve ranks higher than the Ultimate Ears Boom 4 (#61 vs #113 of 175 medium speakers) but is discontinued; its replacement, the Bose SoundLink Revolve (Series II), is rated 3.6/5 at $194 and is still sold new.
The Bose Soundlink Revolve is the better-sounding choice. True 360° sound stays consistent no matter where you stand around it, unlike most portable speakers. It keeps a wired aux input, which the Ultimate Ears Boom 4 lacks. The catch: Strange sizzling treble, peaks and dips.
The Ultimate Ears Boom 4 is the tougher choice. IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. It is rated IP67 against IPX4 for the Bose Soundlink Revolve. It has an adjustable EQ, which the Bose Soundlink Revolve lacks. It plays in stereo from a single unit, unlike the Bose Soundlink Revolve. The tradeoff: Not much improvement over the old ones.
Buy the Bose SoundLink Revolve (Series II), the replacement for the discontinued Bose Soundlink Revolve; it is rated higher for sound quality than the Ultimate Ears Boom 4.
