Short answer: the Bose Soundlink Flex. It ranks #34 of 136 medium speakers by sound quality at $84.99; the Ultimate Ears Roll 2 ranks #125 and costs $100, which makes this an easy call rather than a real tradeoff.
What the Bose Soundlink Flex offers: IP67 rated; rugged enough to survive drops from several feet and floats. Around 12 hours of battery at moderate volume. Watch for: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail
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 Bose Soundlink Flex. It ranks higher for sound quality than the Ultimate Ears Roll 2 and costs less, which settles it without a real tradeoff to make.
If sound quality matters at all to you, skip the Ultimate Ears Roll 2. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
