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.
To ensure that the Earfoams® last as long as possible, we would recommend that you follow our fitting guides and cleaning instructions.
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).
