Comfort Tips need to be replaced once a month for optimum performance and minimal risk of infection, even if they are not visibly damaged or soiled.
It is important to replace the comfort tips when:
- When it becomes discolored or appears soiled.
- When feedback starts, becomes more frequent, or when the iHEARHD does not stay in the correct position in the ear.
- It has been in use for at least a month.
