Short answer: the Tribit Stormbox Mini+. It ranks #110 of 136 medium speakers by sound quality at $29.96; the Ultimate Ears Roll 2 ranks #125 and costs $100, which makes this an easy call rather than a real tradeoff.
What the Tribit Stormbox Mini+ offers: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls, AUX input, microSD card playback. Watch for: Not a great sounding speaker, really weak bass.
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 Tribit Stormbox Mini+. It ranks higher for sound quality than the Ultimate Ears Roll 2 and costs less, so the other one has nothing left to offer.
Neither of these is a sound-quality pick. Look higher up the 136 medium speakers if that is what you are optimizing for.
