Short answer: the Soundcore 3. It ranks #62 of 157 medium speakers by sound quality, rated 3.4/5, at $59.99; the Ultimate Ears Wonderboom 4 ranks #99, rated 2.9/5, and costs $78.95, so there is little reason to consider the other one.
The Soundcore 3 is the better-sounding, longer-running option. Identical in acoustic design and performance to the retailer variant Soundcore Select 2. It is rated for 24 hours of battery against 14 for the Ultimate Ears Wonderboom 4. It links with other speakers (PartyCast up to 100 speakers), which the Ultimate Ears Wonderboom 4 cannot. It has an adjustable EQ, which the Ultimate Ears Wonderboom 4 lacks.
What the Ultimate Ears Wonderboom 4 does well: Small size. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Buy the Soundcore 3. It is rated higher for sound quality than the Ultimate Ears Wonderboom 4 and costs less, which makes it the one to get unless you need something the other one does better.
