Can my hearing aids be upgraded?
Can my CIC (completely-in-canal) hearing aids be upgraded or do I need to buy new ones? Also the sound has become muffled and seems to have more base than before.
If you feel the sounds from your hearing aids have changed, I would advise you to return to your hearing aid provider and ask for an up-to-date hearing test and hearing aid service. They will then be able to advise whether your current aids can be reprogrammed or whether you should consider purchasing a new system.
