Short answer: the Sony ULT Field 1. It ranks #100 of 175 medium speakers by sound quality (rated 3.1/5) at $138 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 Sony ULT Field 1 is the better-sounding pick. IP67 rated, survives drops and 1m submersion. It charges over USB-C rather than Micro USB. The catch: Upper midrange peak, rolled off 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 Sony ULT Field 1 at 1.4 lbs (650 g). It keeps a wired aux input, which the Sony ULT Field 1 lacks. The tradeoff: Barely any bass, rolled off treble off axis.
Buy the Sony ULT Field 1. It is rated higher for sound quality, and the Ultimate Ears Roll 2 is discontinued, so it is only available used.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
