Wax guards are tiny white filters in the tip of the speaker unit of your hearing device. Overtime, wax build up can cause the sound of the hearing device to become soft or could block the sound altogether. Disposing of the used filter, and inserting a new filter is all it takes to change your wax guard.
If you notice a difference in the sound quality of a device, it’s likely time to replace the wax guard. The black CeruShield™ disk that comes with the hearing devices includes 8 replacement wax guards. The frequency of changing the wax guard can vary from user to user. It depends on the person and how much wax is produced in the ear. Wax guards are available for purchase online or from your hearing care professional.
Domes should be replaced every 3-6 months or when they become stiff, brittle or discolored. To remove the dome, securely grip the speaker unit and pinch the dome and gently peel it back and off the speaker unit. Next, take a new dome and insert the end of the speaker unit into the opening of the dome and push it in until you feel it secure itself in the dome. You should feel a slight klick.
