Most people who would benefit from hearing aids never get them. A lot of those who do are amazed at the consequent improvement in their own lives. But don’t expect help to produce your hearing as good as fully normal unaided hearing could be. Do not get an aid without first getting an audiogram to be sure your hearing loss is of a kind that can be helped by a hearing device-and that it can’t be assisted by an operation
You will have to decide what is most important to you in a hearing aid. Some aids have advanced features which will make them easier to operate and more adaptable to changing hearing environments, but those attributes might cost more or less need aid to be less attractive.
