The QuietComfort Earbuds II are IPx4 water and sweat resistant. Bose QuietComfort Earbuds II should be cleaned by gently wiping the buds dry. Be careful not to allow any moisture to enter the earbuds through the ports. In addition, be certain not to force any dirt or debris into the ports. Do not blow air into or vacuum the ports or nozzle. For a more thorough cleaning, remove the eartips from the earbuds, then rinse with water and a mild detergent. Be careful not to rinse/submerge the earbuds themselves. Allow the eartips to dry completely before reattaching them to the earbuds. The eartips should be resistant to dirt or the effects of UV radiation, which typically cause some color change. With normal use, the appearance of the tips should remain unchanged through years of use.
