Short answer: the Ultimate Ears Megaboom 4, if you are buying new. The Soundcore Boost “upgraded” 2021 ranks higher than it (#5 vs #170 of 175 medium speakers, 4.4/5 vs 2.1/5) but is discontinued, so only consider it used; the Ultimate Ears Megaboom 4 is still sold new at $200.
The Soundcore Boost “upgraded” 2021 is the better-sounding, lighter pick. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. At 1.3 lbs (590 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. Watch for: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
The Ultimate Ears Megaboom 4 is the longer-running choice. IP67 rated, floats, and finally uses USB-C charging. It is rated for 20 hours of battery against 12 for the Soundcore Boost “upgraded” 2021. It links with other speakers (PartyUp up to 50 speakers), which the Soundcore Boost “upgraded” 2021 cannot. Watch for: A lot of distortion at higher volumes.
Buy the Ultimate Ears Megaboom 4 new; the Soundcore Boost “upgraded” 2021 is no longer sold new, so it only makes sense as a used find.
