| Teresa Hurley | Feb 2, 2022 | Hearing aids have a lifespan. Most models will last between eight and 10 years, but a few can last even longer. Most hearing aids are made from a variety of materials, so they can deteriorate over time. Although most hearing devices have a protective nanocoating, this does not prevent damage and will need to be changed every couple of years.
