Short answer: the Ultimate Ears Megaboom 4, if you are buying new, though neither ranks well in its class. The Soundcore Flare 2 ranks higher than it (#134 vs #170 of 175 medium speakers, 2.6/5 vs 2.1/5) but is discontinued, so only consider it used; the Ultimate Ears Megaboom 4 is still sold new at $200. Both are rated below 3.0/5 among the 175 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Soundcore Flare 2 is the better-sounding, lighter choice. Try Alan Ross’s EQ for it. At 1.3 lbs (600 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 4. The tradeoff: Rolled off treble.
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 Soundcore Flare 2. The tradeoff: A lot of distortion at higher volumes.
Buy the Ultimate Ears Megaboom 4 if you want one new; the Soundcore Flare 2 is discontinued, so only look for it used.
