Short answer: the Bose SoundLink Flex is the sensible current pick for rugged portable use, while the SoundLink Mini remains a compact stereo speaker for indoor listening. Flex floats, carries IP67 protection, uses USB-C, and lasts around 12 hours. The Mini has no water rating, only a 7-hour claim, and relies on a proprietary charging cradle.
Both favor boosted upper bass, but Flex’s warmth can bury midrange detail while the Mini adds rolled-off treble and reported mainboard failures. The Mini’s stereo drivers and aluminum build are still appealing at a desk, whereas Flex is the one you can take outdoors without nursing it.
Buy the Bose SoundLink Flex for floating IP67 protection and a modern rugged portable design.
Buy the Bose SoundLink Mini only for its compact stereo presentation, aux input, and charging cradle.
There is a real gap in water resistance: the Bose Soundlink Flex at IP67 (brief submersion) against the Bose Soundlink Mini, which has no water resistance.
