These are not really the same size class, and that is the honest framing here. The Bogasing M4 ranks #24 of 134 medium speakers at $45.99; the Ultimate Ears Miniroll ranks #12 of 46 small speakers 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 at $45.99 if you want a medium speaker. Buy the Ultimate Ears Miniroll at $49.99 if you want a small speaker instead.
