The right hearing aid sometimes makes a beeping sound about once a day but still functions normally. These are used hearing aids that I've simply no longer require. One hearing aid box will be included. The brand of the box may not match the brand of hearing aids.
They use SIZE 13 (orange) batteries. This model includes a BlueTooth feature and can be connected to your iPhone to stream music and other audio wirelessly. It was a very life changing feature for me.
