Short answer: the Ultimate Ears Boom 4 if sound quality matters most, the Tribit Stormbox Mini+ if price matters most. The Ultimate Ears Boom 4 ranks #88 of 136 medium speakers at $105. The Tribit Stormbox Mini+ ranks #110 at $29.96, $75.04 cheaper.
What the Ultimate Ears Boom 4 offers: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. 15 hour battery. Customizable EQ and speaker-pairing via the UE app. Watch for: Not much improvement over the old ones. Weak bass extension and thuddy bass. Gets distorted above 90%
What the Tribit Stormbox Mini+ offers: 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. Watch for: Not a great sounding speaker, really weak bass.
Buy the Ultimate Ears Boom 4 when sound quality outweighs the price for you, and the Tribit Stormbox Mini+ when the price outweighs sound quality instead.
The Tribit Stormbox Mini+ is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
