Short answer: the Soundcore 3. It ranks #62 of 157 medium speakers by sound quality (rated 3.4/5) at $59.99 and is still sold new; the Ultimate Ears Wonderboom ranks #102 (rated 2.9/5) and is discontinued, so it is only an option used.
The Soundcore 3 is the better-sounding, longer-running pick. Identical in acoustic design and performance to the retailer variant Soundcore Select 2. It is rated for 24 hours of battery against 10 for the Ultimate Ears Wonderboom. It links with other speakers (PartyCast up to 100 speakers), which the Ultimate Ears Wonderboom cannot. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks.
The case for the Ultimate Ears Wonderboom: IP67 rated and floats. The tradeoff: Not stereo, barely any bass, recessed treble.
Buy the Soundcore 3. It is rated higher for sound quality and still sold new, while the Ultimate Ears Wonderboom is discontinued.
