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.
Buy the Teufel Boomster Go if sound quality matters more than the price. Buy the Ultimate Ears Miniroll if the price matters more than sound quality.
