Short answer: the Ultimate Ears Wonderboom 4 for better sound quality, the Tribit Stormbox Mini+ for the lower price, though neither ranks well in its class. The Ultimate Ears Wonderboom ranks higher than the Tribit Stormbox Mini+ (#112 vs #142 of 175 medium speakers) but is discontinued. Its replacement, the Ultimate Ears Wonderboom 4, is rated 2.9/5 at $74.50; the Tribit Stormbox Mini+ is rated 2.5/5 at $31.99, $42.51 cheaper. Both are rated below 3.0/5 among the 175 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Ultimate Ears Wonderboom is the better-sounding, lighter choice. IP67 rated and floats. At 0.9 lbs (425 g) it weighs noticeably less than the Tribit Stormbox Mini+ at 1.2 lbs (544 g). Watch for: Not stereo, barely any bass, recessed treble.
What the Tribit Stormbox Mini+ does well: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls, AUX input, microSD card playback. It keeps a wired aux input, which the Ultimate Ears Wonderboom lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Wonderboom. The catch: Not a great sounding speaker, really weak bass.
Buy the Tribit Stormbox Mini+ if price matters most. For better sound quality, the Ultimate Ears Wonderboom 4, the replacement for the discontinued Ultimate Ears Wonderboom, is rated higher but costs $74.50.
