Short answer: the Ultimate Ears Miniroll for tone, the Bogasing M4 if you want the super bass mode. The Miniroll has good clarity and detail through the mids and highs with a warmer balance than most ultra-portables its size, though its bass is not as deep as the best rated speakers. The M4 is at its most balanced in super bass mode but is otherwise a bit harsh and thin.
On the Bogasing M4 side: Use super bass mode for the most balanced sound. The tradeoff: A bit harsh and thin sounding.
The case for the Ultimate Ears Miniroll: 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 Bogasing M4 ($45.99) for a medium speaker; the Ultimate Ears Miniroll ($49.99) suits a small speaker instead.
There is a real battery-life gap here: the Bogasing M4 is rated for 24 hours, the Ultimate Ears Miniroll only 12 hours.
