Short answer: the Ultimate Ears Wonderboom 2, though neither ranks well in its class. It ranks #111 of 175 medium speakers by sound quality (rated 2.9/5) at $80 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. 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 Ultimate Ears Wonderboom 2 is the better-sounding choice. IP67 rated and floats. Watch for: Not stereo, barely any bass, recessed treble.
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 noticeably less than the Ultimate Ears Wonderboom 2 at 0.9 lbs (420 g). It keeps a wired aux input, which the Ultimate Ears Wonderboom 2 lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom 2 lacks. Watch for: Barely any bass, rolled off treble off axis.
Buy the Ultimate Ears Wonderboom 2. It is rated higher for sound quality; the Ultimate Ears Roll 2 is no longer sold new.

The Two Speakers In Full
Ultimate Ears Wonderboom 2: $80 Amazon $80 eBay
Newer model: the Ultimate Ears Wonderboom 4, ranked higher, rated 2.9/5, released Jun 2024.
Older model: the Ultimate Ears Wonderboom (ranked lower, rated 2.9/5). See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
Pros: IP67 rated and floats. Compact and light enough to toss in a bag. Measured bass extension of 82Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. Slightly boosted 93Hz upper bass Dip at 9kHz. 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 2019. Not technically a 360 speaker, only front and rear.
