What led Rayovac to innovate Pro Line Advanced?


Our goal was to answer the unmet needs in the hearing aid battery market. We looked at new Pro Line as a solution to issues we have been hearing from both hearing aid wearers and hearing health professionals for years. The new Pro Line Advanced battery system design was rooted in hearing aid battery consumer research we conducted along with input from hearing health professionals.

What were the findings of your research?

We found that the top two things hearing aid users are looking for when it comes to their hearing aid batteries are: longer battery life and an easy-to-use package. The new Pro Line Advanced delivers on both.

This Ask the Expert is an excerpt from the interview, NEW Pro Line Advanced.
