Sleeep® Earfoams® generally last about 2-3 months depending on how they are handled, used, and your body chemistry (earwax, oils, etc.). Naturally, increased use will decrease their life.
It is important that Earfoams® are regularly inspected for serviceability and are maintained in accordance with our instructions. Be sure to replace your Earfoams® when they start to “flake”, tear, or lose their memory foam properties (e.g. the foam expands quickly rather than slowly). You can purchase replacement Earfoams® at the links below.
