Earfoams generally last about 1 month depending on how they are handled, used, and your body chemistry (earwax, oils, etc.). Naturally, frequent use will shorten their lifespan.
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 loses its slow rebound time). You can purchase replacement Earfoams at the links below.
