Short answer: the Ultimate Ears Megaboom 3, if you are buying new. The Soundcore Boost “upgraded” 2021 ranks higher than it (#5 vs #108 of 175 medium speakers, 4.4/5 vs 3.0/5) but is discontinued, so only consider it used; the Ultimate Ears Megaboom 3 is still sold new at $191.99.
The Soundcore Boost “upgraded” 2021 is the better-sounding, deeper-bass pick. A very neutral good sounding inexpensive small speaker with quite deep bass for the size. Its bass reaches about 56Hz before falling 10dB, against 70Hz for the Ultimate Ears Megaboom 3. At 1.3 lbs (590 g) it weighs noticeably less than the Ultimate Ears Megaboom 3 at 2 lbs (925 g). It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 3. The catch: Slight DSP tuning issue which makes bass get lighter at times at very low volumes, examples in oluv’s video.
The Ultimate Ears Megaboom 3 is the longer-running choice. IP67 rated, floats, and survives drops from up to 1 meter. 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: Not stereo, barely any bass.
Buy the Ultimate Ears Megaboom 3, since the Soundcore Boost “upgraded” 2021 is discontinued and only worth hunting down used.

Ultimate Ears Megaboom 3: $191.99 Amazon $191.99 eBay
Newer model: the Ultimate Ears Megaboom 4, ranked lower, rated 2.1/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life: about double most speakers this size. Measured bass extension of 70Hz (-10dB).
Cons: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
