Short answer: the Ultimate Ears Miniroll, if you are buying new. The Tribit Stormbox Micro ranks higher than it (#5 vs #12 of 50 small speakers, 4.3/5 vs 3.9/5) but is discontinued, so only consider it used; the Ultimate Ears Miniroll is still sold new at $49.99.
The Micro is quite neutral, with a specific volume ceiling. Its own review calls it quite neutral with only slight hollowness in the mids, and its built-in strap is genuinely useful for attaching it to gear. The tradeoff is real: it gets murky and slightly sharp near max volume, and its boosted bass distorts when pushed loud. The down-firing passive radiator also needs a flat surface underneath or the bass gets muffled. Notably, the review itself recommends spending a little more for the newer Stormbox Micro 2, which goes louder and deeper.
The Miniroll offers good clarity with a warmer balance, but at lower output. It has good clarity and detail in the mids and highs with a warmer tonal balance than most ultra-portables its size. Its own cons are limited to lacking a companion app or EQ adjustment, and bass isn’t quite as deep as the best-rated speakers in its class. Its max volume of 83dB trails the Micro’s 93dB.
Everything else matches: both are IP67 rated and support TWS pairing, though the Miniroll adds Auracast-based PartyUp mode limited to other Miniroll units.
Buy the Tribit Stormbox Micro for the more neutral sound and higher max volume, while accepting the volume-ceiling distortion the review flags, and consider the newer Micro 2 for a modest premium.
Buy the Ultimate Ears Miniroll if a warmer tonal balance and slightly longer battery life matter more to you than outright loudness.

The Two Speakers In Full
Tribit Stormbox Micro: $40 Discontinued eBay
Newer model: the Tribit Stormbox Micro 3, ranked lower, rated 4.2/5.
Pros: Quite neutral. Slight hollowness in the mids. Built in strap is super useful for attaching it to things. Highly recommend spending a little more on the Micro 2 which goes louder and deeper. To have it aimed directly at you unclip the strap and the speaker will sit upright with a slight lean back. Measured bass extension of 62Hz (-10dB).
Cons: Gets murky and slightly sharp near max volume; boosted bass distorts when pushed loud. Down-firing passive radiator needs a flat surface underneath or the bass gets muffled. Discontinued and no longer sold new; superseded by the Stormbox Micro 2.
