Unused Primo HA-3.5, comes with Panasonic batteries. This is a hearing amplifier called "Chougo." I remember the retail price was close to 20,000 yen. I bought it for people with hearing difficulties at gatherings, but I never used it and have kept it at home. It has a very simple design; it works by placing it in your ear and applying pressure to the cushion part. The volume is adjusted with a slide, so it's easy to understand and simple to use, suitable for anyone. All included accessories are present. - Model Name: Primo HA-3.5 - Brand: Panasonic - Included Items: Batteries (Panasonic) - Condition: Unused - Warning Label: Contains warnings Will be sent via anonymous Mercari delivery.
