This app is a premium version to help the developer.
NOTE: This app has the same options as the "Headphones - Left Right" app, but it is paid to help the developer. Please do not download it unless that is your intention. If you just want an app to check hearing aids without spending money, you can download the aforementioned app.
A simple and safe way to check that both sides of your hearing aids are working correctly.
You can also use it to test sound systems; bluetooth headphones among others.
We hope it helps you!
