Isolate® tips generally last about 1 month 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 tips are regularly inspected for serviceability and are maintained in accordance with our instructions. Be sure to replace your tips 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.
DO NOT USE THE EARPLUGS IF THERE ARE ANY SIGNS OF DETERIORATION TO THE EARFOAMS® - THE EARPLUGS SHOULD NOT BE USED AGAIN UNTIL THE TIPS HAVE BEEN REPLACED.
