Short answer: the Sony ULT Field 1. It ranks #76 of 136 medium speakers by sound quality at $98; the Ultimate Ears Roll 2 ranks #125 and costs $100, which makes this an easy call rather than a real tradeoff.
What the Sony ULT Field 1 offers: IP67 rated, survives drops and 1m submersion. Real-world battery around 28+ hours with ULT (bass boost) mode off. Stereo-pairs with a second ULT Field 1. Watch for: Upper midrange peak, rolled off treble
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 Sony ULT Field 1. 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.
