Short answer: the Xiaomi Sound Party. It ranks #20 of 179 medium speakers by sound quality (rated 4.1/5) at $135.84 and is still sold new; the Ultimate Ears Roll 2 ranks #164 (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 Xiaomi Sound Party is the better-sounding, longer-running pick. A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. It is rated for 26 hours of battery against 9 for the Ultimate Ears Roll 2. It charges over USB-C rather than Micro USB. The tradeoff: The sound evidence is mixed rather than universally glowing.
The Ultimate Ears Roll 2 is the lighter option. A thin, flat waterproof speaker with a bungee cord for hanging from a hook or door handle, now discontinued. At 0.7 lbs (330 g) it weighs much less than the Xiaomi Sound Party at 2.6 lbs (1.2 kg). It keeps a wired aux input, which the Xiaomi Sound Party lacks. Watch for: Barely any bass, rolled off treble off axis.
Buy the Xiaomi Sound Party. It is rated higher for sound quality, and the Ultimate Ears Roll 2 is discontinued, so it is only available used.
