Short answer: the W-King D8 Mini. It ranks #106 of 136 medium speakers by sound quality at $38.93; the Ultimate Ears Roll 2 ranks #125 and costs $100, which makes this an easy call rather than a real tradeoff.
What the W-King D8 Mini offers: 30W output with switchable indoor/outdoor EQ modes. IPX6 rated with a 5000mAh battery. Watch for: Recessed midrange, harsh treble. Bass doesn’t go as deep as others.
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 W-King D8 Mini. It ranks higher for sound quality than the Ultimate Ears Roll 2 and costs less, so there is no real case for the other one.
Neither of these is a sound-quality pick. Look higher up the 136 medium speakers if that is what you are optimizing for.
There is a real battery-life gap here: the W-King D8 Mini is rated for 24 hours, the Ultimate Ears Roll 2 only 9 hours.
