Wax buildup is one of the leading causes for hearing aid repair. When this occurs, the sound coming through your hearing aids may be weak, intermittent, distorted or nonexistent. 

Replacing the wax guards is as easy as it is important and should be done every three to five months or whenever you sense that your hearing aids are not working well.

These wax guards are specifically designed and sized for the C-Series and Luna/xMini models. They will not work on the H, R, S or A series hearing aids
