The Miniroll has good clarity and detail in the mids and highs with a warmer tonal balance than most ultra-portables its size, but its bass is not quite as deep as the best rated speakers.

The Two Speakers In Full
Tribit Stormbox Micro 2: $59.99 Amazon AliExpress eBay
Newer model: the Tribit Stormbox Micro 3, ranked lower, rated 4.2/5.
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. Measured bass extension of 65Hz (-10dB).
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
