Short answer: the Ultimate Ears Wonderboom 4 on measured sound quality, the Tribit Stormbox Mini+ on price, though neither ranks well in its class. The Ultimate Ears Wonderboom 4 ranks #109 of 175 medium speakers, rated 2.9/5, at $74.50. The Tribit Stormbox Mini+ ranks #142, rated 2.5/5, at $31.99, $42.51 cheaper. Both are rated below 3.0/5 among the 175 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Wonderboom 4 is the better-sounding, lighter choice. At 0.9 lbs (420 g) it weighs noticeably less than the Tribit Stormbox Mini+ at 1.2 lbs (544 g). The catch: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
Why pick the Tribit Stormbox Mini+: 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 supports AAC Bluetooth, which the Ultimate Ears Wonderboom 4 lacks. It keeps a wired aux input, which the Ultimate Ears Wonderboom 4 lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom 4 lacks. The catch: Not a great sounding speaker, really weak bass.
Buy the Ultimate Ears Wonderboom 4 if sound quality is the priority over the price, or the Tribit Stormbox Mini+ if the price is the priority over sound quality.
