Short answer: the Soundcore Motion 100. It ranks #39 of 136 medium speakers by sound quality at $47; the Ultimate Ears Wonderboom 4 ranks #84 and costs $59.99, so there is not much of a tradeoff to weigh.
What the Soundcore Motion 100 offers: Use Oluv’s EQ for the flattest response Watch for: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices.
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.
Buy the Soundcore Motion 100. It ranks higher for sound quality than the Ultimate Ears Wonderboom 4 and costs less, so the other one has nothing left to offer.
