We recommend replacing your Earfoams once a month to ensure they’re in the best possible condition and safe for use. 

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 here.
