Short answer: the Stormbox Micro 2, and it’s the class leader at a lower price. It ranks #1 of 47 small speakers at $50; the Boom Go 3i ranks #2 at $79.99, $30 more.
The Boom Go 3i’s real edge is water sealing. IP68 rated for full submersion and dust protection, against the Micro 2’s IP67, plus an RGB light strip and a USB-C port that doubles as a power bank. Our notes describe the sound as a bit piercing and metallic, with a peak at 10kHz.
The Micro 2 is described as best in class, with much deeper bass than most speakers its size and a genuinely neutral tuning, plus a built-in strap that doubles as a stand. Its one real flaw is finicky phone charging.
Buy the Stormbox Micro 2 for the better sound at the lower price. Buy the Boom Go 3i if the extra IP68 sealing is worth $30 to you.

Tribit Stormbox Micro 2: $34.19 Aliexpress Amazon
Pros: Best in class sound. Much deeper bass than most other speakers in the size. Built in strap is super useful for attaching it to things. Very neutral. To have it aimed directly at you unclip the strap and the speaker will sit upright with a slight lean back.
Cons: Finicky phone charging, which doesn’t usually work.
Setup: Use in Music EQ mode, when you switch to custom it’s not able to boost the bass properly as it is missing an EQ band that Music EQ mode uses
