Short answer: the Soundcore Boom 3i. It ranks #31 of 175 medium speakers by sound quality, rated 4.0/5, at $118.99. The Tribit Stormbox Mini+ ranks #142, rated 2.5/5, at $31.99, $87 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Soundcore Boom 3i is the better-sounding, longer-running choice. Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. It is rated for 16 hours of battery against 12 for the Tribit Stormbox Mini+. The tradeoff: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The Tribit Stormbox Mini+ is the lighter pick. 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. At 1.2 lbs (544 g) it weighs noticeably less than the Soundcore Boom 3i at 1.7 lbs (783 g). It keeps a wired aux input, which the Soundcore Boom 3i lacks. It plays in stereo from a single unit, unlike the Soundcore Boom 3i. The catch: Not a great sounding speaker, really weak bass.
Buy the Soundcore Boom 3i. It is rated higher for sound quality, and the $87 you would save on the Tribit Stormbox Mini+ does not close the gap.
