How should I clean and maintain my Beats Flex?
Clean Beats Flex regularly with a soft lint-free cloth to prevent ear infections and skin irritation. Do not get moisture in any openings, and do not use aerosol sprays, solvents, or abrasives. If a skin problem develops, discontinue use and consult a physician if the problem persists.
