Short answer: the Ultimate Ears Wonderboom 4. It ranks #84 of 136 medium speakers by sound quality at $59.99; 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 4 offers: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy. Not much improvement over the previous Ultimate Ears Wonderboom 3 besides the USB-C charging port.
