Short answer: the Ultimate Ears Boom 4, if you are buying new. The Soundcore Boost “original model” pre-2021 ranks higher than it (#14 vs #113 of 175 medium speakers, 4.2/5 vs 2.9/5) but is discontinued, so only consider it used; the Ultimate Ears Boom 4 is still sold new at $129.99.
The Soundcore Boost “original model” pre-2021 is the better-sounding pick. At 1.3 lbs (590 g), Soundcore Boost “original model” pre-2021 combines 1.75” x 2 active drivers + passive radiator with Bluetooth and aux. It keeps a wired aux input, which the Ultimate Ears Boom 4 lacks. The catch: Careful placement is still important for balanced bass.
The Ultimate Ears Boom 4 is the tougher pick. IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. It is rated IP67 against IPX5 for the Soundcore Boost “original model” pre-2021. 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 Soundcore Boost “original model” pre-2021 is discontinued and only worth hunting down used.
