Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Bogasing M4 ranks #26 of 142 medium speakers by sound quality at $45.99; the Ultimate Ears Miniroll ranks #12 of 47 small speakers by sound quality at $49.99.
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.
