Short answer: the Ultimate Ears Wonderboom 4. It ranks #84 of 136 medium speakers by sound quality at $59.99; the Sony SRS-XB20 ranks #94 and costs $129, so there is not much of a tradeoff to weigh.
What the Sony SRS-XB20 offers: IPX5 rated pill shape slides easily into a bag. Set against that: Sounds thin at higher volumes.
The case for the Ultimate Ears Wonderboom 4: Small size. The catch: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Buy the Ultimate Ears Wonderboom 4. It ranks higher for sound quality than the Sony SRS-XB20 and costs less, so there is no real case for the other one.
