With SoundLink Flex, we’ve stretched beyond the required testing parameters — in this case an IP67-rated product — to ensure that your speaker will long outlast an accidental drop into water or getting exposed to a dust storm. The SoundLink Flex is completely dust-tight, can withstand water splashes as well as the pressure of being immersed in water up to 3.3 ft. (1 m) deep, for up to 30 minutes. To ensure further protection from water, dust, and debris, the transducer and passive radiators underneath the steel grille are built with rugged, waterproof materials.
