Short answer: the Tronsmart T8. It ranks #52 of 150 medium speakers by sound quality, rated 3.6/5, at $49.99; the Ultimate Ears Wonderboom 4 ranks #95, rated 2.9/5, and costs $59.99, so there is not much of a tradeoff to weigh.
What the Tronsmart T8 does well: Two upward firing drivers, a woofer and two passive radiators spread sound evenly around the speaker, so placement matters less. The catch: Against the Xiaomi Sound Outdoor, listeners in Mateusz Cholewa’s comparison found the T8 harsh and tiring, and Techder Audios’ test showed the Xiaomi Sound Party with deeper, heavier bass.
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 Tronsmart T8. 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.

The Two Speakers In Full
Tronsmart T8: $49.99 Best Buy Tronsmart eBay
Pros: Two upward firing drivers, a woofer and two passive radiators spread sound evenly around the speaker, so placement matters less. In AudioPro Reviews’ and Dresser’s comparisons most listeners preferred it to the JBL Flip 6, JBL Flip 7 and Ultimate Ears Megaboom 3 for its fuller body and less fatiguing treble, and Audioreviews.org found it stayed clean at maximum volume. It is rated for 40W, with IPX7 waterproofing, an 18 hour battery rating, app EQ, lights, a volume wheel, aux input, TF card playback, a lanyard and stereo pairing.
Cons: Against the Xiaomi Sound Outdoor, listeners in Mateusz Cholewa’s comparison found the T8 harsh and tiring, and Techder Audios’ test showed the Xiaomi Sound Party with deeper, heavier bass. Josh’s Gadgets and More preferred the cheaper Vortex Blast for smoother highs and deeper bass. Bass is rated only down to 56Hz.
