This is a valid question, especially since the Beats Flex does not have an IP rating (which would then make the water resistance measurable). On the web, you can only find information that the USB C connector is waterproof and that the controls are somewhat sealed. In my view, this does not justify the designation "splashproof". I don't know why Digitec has this in the specs - the manufacturer Beats doesn't mention anything about it. I will certainly leave mine in the dry.
