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.

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.

Phone app works great, watch app needs an update

The phone app is excellent and works very well. Well done Resound for developing it and trying to keep it up to date with each iteration of iOS.

Unfortunately I cannot get the Apple Watch app to work properly. The watch app requires the phone app to be on all the time with the phone screen activated. What it needs is the phone app to operate in background not exclusive mode and make independent adjustments on the fly with the watch app.

Happy to review again when there is a new update from resound. It must be hard developing for a perpetual moving target. Hope they continue developing the watch app, in theory it’s a killer feature and the resound to stick with Resound.

Hi, Thanks for your comment. This is an issue we are working on, so the watch can control the hearing aids without the app is actively running on the phone. br app support
