Set up and customize hearing with the Sony Hearing Control App. These are prescription grade sound quality hearing aids. Purchased Dec. 2023 (1year,4month ago) for our mom but she refused to use them. Opened box used but like new condition. Comes with everything in the pictures. This was close to $800 brand new for us, looking to sell as we have no use for them. To be clear, we did opene everything us and showed my mom how it looks set up but nothing was every used/tried on.
