Short answer: the Ultimate Ears Wonderboom. It ranks #87 of 136 medium speakers by sound quality at $79; the Ultimate Ears Roll 2 ranks #125 and costs $100, so there is not much of a tradeoff to weigh.
What the Ultimate Ears Wonderboom offers: IP67 rated and floats. Compact, light, and simple to use. Watch for: Not stereo, barely any bass, recessed treble. Dip at 9khz. Low mid bass distortion. Not technically a 360 speaker, only front and rear.
What the Ultimate Ears Roll 2 offers: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. Built-in bungee cord for hanging from a hook, nail, or door handle. Life-resistant waterproof/dustproof shell. Watch for: Not stereo. Barely any bass, rolled off treble off axis
Buy the Ultimate Ears Wonderboom. It ranks higher for sound quality than the Ultimate Ears Roll 2 and costs less, so the other one has nothing left to offer.
The Ultimate Ears Roll 2 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
