Short answer: the Teufel Boomster Go. It ranks #7 of 47 small speakers by sound quality; the Ultimate Ears Miniroll ranks #12.

On the Teufel Boomster Go side: Pretty deep bass and quite balanced overall for the size. Set against that: Distortion becomes audible above roughly 75% volume; at max volume up close it gets unclear and tinny.

What the Ultimate Ears Miniroll gets right: Good clarity and detail in the mids/highs with a warmer tonal balance than most ultra-portables its size. The tradeoff: Bass not quite as deep as the best rated speakers.
