Sound settings

Have been using this app for couple of years now. I used to be able to control level of sound independently in each ear but this is no longer possible. I can’t see the point of having slider controls for each hearing aid if you should alter one of them the other follows suit.

Thank you for reply.
I have always separated the sliders. But now when I do it and alter L or R slider They follow each other (as previously stated) and the volume remains at same level for each hearing aid. I then have to go into accessibility setting on phone so I can change volume independently. Even after this if I try again via the app they will not change independently.

Reviewed review

Have now got the app working and am back in familiar territory, so happy. I was pleased with the old Resound app but the new features are a big improvement. The equaliser does make a difference. Saving favourite settings is very useful.
My problem was not being able to exit demo mode. From the ‘ more’ screen the advise was to exit the app - reboot the HAs and then go back into the app. Then you go around again and again. What you actually need to do is go to settings/accessibility/made for iPhone etc and scroll down. Here you will find ‘forget this device. Press that - reboot the HAs by opening and closing and then go back into the app. This forces the app to start from scratch and happy days are here again.

Thanks for your comment. To leave Demo mode you have to open the app, click on the "More" menu and disable Demo mode.

Reverts to audio streaming when phone rings

Please ignore the second part of this review. I have now fixed the issue I was having and have upgraded the stars to 5. This app is now now works perfectly.

This app works well but for one thing. It always switches to audio streaming when the phone rings which is so annoying. I have set my iPhone 7 to ‘never through hearing aids in the audio routing within the accessibility option in the system software. Also it switches to hearing aids when in the car instead of through the car radio. Has anyone else experienced this. Comments please and comments/suggestion from resound please. Then it will be 5 stars.
