Short answer: the Ultimate Ears Megaboom 3. It ranks #108 of 175 medium speakers by sound quality (rated 3.0/5) at $191.99 and is still sold new; the Ultimate Ears Roll 2 ranks #161 (rated 2.2/5) and is discontinued, so it is only an option used. The Ultimate Ears Roll 2’s replacement, the Ultimate Ears Miniroll, is still sold new.
The Ultimate Ears Megaboom 3 is the better-sounding, longer-running choice. IP67 rated, floats, and survives drops from up to 1 meter. It is rated for 20 hours of battery against 9 for the Ultimate Ears Roll 2. Watch for: Not stereo, barely any bass.
The Ultimate Ears Roll 2 is the lighter choice. Thin, flat profile fits easily in a bag or purse. At 0.7 lbs (330 g) it weighs much less than the Ultimate Ears Megaboom 3 at 2 lbs (925 g). It keeps a wired aux input, which the Ultimate Ears Megaboom 3 lacks. Watch for: Barely any bass, rolled off treble off axis.
Buy the Ultimate Ears Megaboom 3. It is rated higher for sound quality and still sold new, while the Ultimate Ears Roll 2 is discontinued.

The Two Speakers In Full
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.
