Short answer: the Ultimate Ears Boom 3, though neither ranks well in its class. It ranks #114 of 175 medium speakers by sound quality (rated 2.9/5) at $134.99 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. 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 Boom 3 is the better-sounding, longer-running pick. Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp. It is rated for 15 hours of battery against 9 for the Ultimate Ears Roll 2. It plays in stereo from a single unit, unlike the Ultimate Ears Roll 2. The tradeoff: Not stereo, barely any bass, recessed treble.
The Ultimate Ears Roll 2 is the lighter pick. Thin, flat profile fits easily in a bag or purse. At 0.7 lbs (330 g) it weighs much less than the Ultimate Ears Boom 3 at 1.3 lbs (608 g). It keeps a wired aux input, which the Ultimate Ears Boom 3 lacks. Watch for: Barely any bass, rolled off treble off axis.
Buy the Ultimate Ears Boom 3. It is rated higher for sound quality, and the Ultimate Ears Roll 2 is discontinued, so it is only available used.

The Two Speakers In Full
Ultimate Ears Boom 3: $134.99 Amazon $134.99 eBay
Newer model: the Ultimate Ears Boom 4, ranked higher, rated 2.9/5, released Jun 2024. See every Ultimate Ears Wonderboom, Boom and Megaboom generation.
Pros: Rich and warm bass without muddying mix, crisp highs, excellent 15-hour battery life, stable Bluetooth connectivity, IP67 rated and floats, rugged fabric shell, can pair up to 150 speakers via PartyUp. Measured bass extension of 91Hz (-10dB).
Cons: Not stereo, barely any bass, recessed treble. 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 2021. Lots of mentions of failing batteries on amazon. Not technically a 360 speaker, only front and rear.
