A. 1. Ensure that your hearing aids are in streaming mode and that the app is set to stream audio. Check the app settings for any audio streaming options. 2. Restart both your hearing aids and your smartphone to reset the connection.

B. 3. Check if the audio source (like music or video) is compatible with your hearing aids. Some formats may not be supported. 4. If streaming still does not work, try using a different audio app to see if the issue is app-specific.
