Short answer: the Ultimate Ears Miniroll for mids and highs, the Teufel Boomster Go for bass depth. The Miniroll brings good clarity and detail through the mids and highs with a warmer tonal balance than most ultra-portables its size, though its bass is not quite as deep as the best rated speakers. The Boomster Go counters with pretty deep bass and quite balanced sound for the size, but distortion becomes audible above roughly 75% volume.
Buy the Ultimate Ears Miniroll new; the Teufel Boomster Go is no longer sold new, so it only makes sense as a used find.
