I updated the book in July 2018 to include the latest hearing aids and my own experiences wearing them. I still believe that this is the only hearing aid book you will ever need. The third edition of The Little Book of Hearing Aids has been updated to reflect the new hearing aids from the major brands, to explain why buying rechargeable hearing aids might be a good idea and there is a whole new section answering the frequently asked questions about invisible hearing aids. If you or someone you know is looking to buy hearing aids, well then this book will give them the information they need to do so with confidence.
