Short answer: the Stormbox Micro 3 if you’re willing to EQ it, the Miniroll if you want good sound with no setup. The Stormbox Micro 3 ranks #6 of 47 small speakers against the Miniroll’s #12, for $10 more.
The two speakers take opposite approaches to sound quality. The Miniroll’s pros describe “good clarity and detail in the mids/highs with a warmer tonal balance than most ultra-portables its size,” with its only real weakness being bass that isn’t as deep as the best-rated speakers in the class. The Stormbox Micro 3 has deeper bass extension on paper, credited in its own pros as “deeper bass than the last one,” but its cons are blunt that this bass is “thuddy” and “distorted” by default and needs an EQ to fix, with treble also flagged as a weak point. If you don’t want to spend time in an EQ app, the Miniroll is the more finished product out of the box; the Stormbox Micro 3 has an EQ built in specifically because it needs one.
Battery life clearly favors the Stormbox Micro 3: 24 hours rated against 12 hours for the Miniroll, and it also doubles as a USB-C power bank, which the Miniroll cannot do.
What the Stormbox Micro 3 has that the Miniroll lacks: an app with 9-band EQ, a higher IP68 rating against IP67, and roughly 4x the rated output power (13W versus 3W RMS).
What the Miniroll has that the Stormbox Micro 3 lacks: PartyUp/Auracast party mode for linking multiple Miniroll units, and a lighter build at 279 g against 330 g.
Buy the Tribit Stormbox Micro 3 if you’re comfortable using its EQ to fix the default bass, and want longer battery life and a power bank in the same unit.
Buy the Ultimate Ears Miniroll if you want a speaker that sounds balanced right out of the box and don’t want to bother with EQ settings.
