Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Bose Soundlink Flex ranks #36 of 142 medium speakers by sound quality at $159; the Minirig Mini ranks #4 of 47 small speakers by sound quality at $100.
The case for the Bose Soundlink Flex: IP67 rated; rugged enough to survive drops from several feet and floats. Watch for: Not stereo.
What the Minirig Mini does well: Very neutral. The catch: Calls itself splash resistant and has no official water rating.
One note: the Minirig Mini is discontinued, but it still ranks #4 of 47 small speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Bose Soundlink Flex at $159 for a medium speaker, or the Minirig Mini at $100 for a small speaker instead.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
