Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #109 of 175 medium speakers by sound quality (rated 2.9/5) at $74.50 and is still sold new; the Tribit Stormbox Mini ranks #148 (rated 2.4/5) and is discontinued, so it is only an option used. The Tribit Stormbox Mini’s replacement, the Tribit Stormbox Mini+, is rated 2.5/5 at $31.99. 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 pick. At 0.9 lbs (420 g) it weighs much less than the Tribit Stormbox Mini at 1.6 lbs (708 g). The catch: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the Tribit Stormbox Mini does well: IPX7 waterproof, excellent battery life (12 hours), RGB LED lighting, app support with AAC codec, true wireless stereo (TWS) capability, USB-C charging. 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 plays in stereo from a single unit, unlike the Ultimate Ears Wonderboom 4. Watch for: Lacking quite a bit of bass.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality; the Tribit Stormbox Mini is no longer sold new.
