In-The-Canal (ITC) hearing aids are custom-molded to fit inside the ear canal, providing a comfortable and discreet fit. However, comfort can vary from person to person. Factors affecting comfort include the custom fit, size, earmold material, ear canal sensitivity, and proper fitting. Regular check-ups with an audiologist are essential to ensure optimal fit. Consult a hearing healthcare professional or audiologist to assess specific needs, fit the hearing aids, and address any comfort issues.
