Connectivity Loss

I have used this program for nine months to connect my hearing aids to my iPhone and have been able to stream music, listen to audible books and use the phone. The sound is decent – nothing an audiophile would write home about – but very convenient and I love being able to listen to music when those around me don't even know! Then a few days ago my hearing aids stopped connecting. I am not running a different iOS version; I have paired it several times and it still will not play even though it shows it is connected through the accessibility option on the iPhone – but the ReSound app will not connect – very frustrating after having it work so well for nine months. One other big issue is how difficult it makes it to use my Bluetooth in my car – when my hearing aids were working – they competed with playing music using my Bluetooth sound system in the car. I hope these app developers keep working on improving this app – it has great potential – but I will look at other brands when I upgrade my hearing aids to see if their Bluetooth connectivity/reliability is any better.

Still loses connection

I’ve been using the Resound paired with a Cochlear device, and have had nothing but trouble with it and the apps. I traded a Samsung S8 Edge phone for an iPhone 6S plus ( my sister’s) so it would be more compatible. I’ve had this for over a year. Started having more trouble with dropping Bluetooth. Blaming the s6 for running out of memory (16GB), I recently bought a new iPhone XS. With 64GB. The past few days, the Resound worked great. Today it won’t connect at all. I’ve loaded and reloaded the app. Nothing. The iPhone Bluetooth works with everything else. When trying to listen to TV through the tv sound adapter, the adapter icon shows in the app, and the yellow and green lights on the adapter are steady, showing that the device is connected to the iPhone, but the hearing aid won’t connect to the app. Finally it lost Bluetooth connection altogether. I’m wearing a demo HA because my own has been sent back to the manufacturer for the upteenth time for various problems. The two stars are for both app AND hearing aid! I would have given one star but will give credit for those days when it DOES work right, because then it’s great. I think the engineers at Resound need to go back and start all over again from scratch and then introduce a hearing device that will work consistently instead of one that only works part time!!

Unreliable Bluetooth connectivity

I have been using Resound LINX2 hearing aids since 2015... Lately, updates to iOS and the Resound “Smart” application have introduced problems maintaining Bluetooth connectivity to my iPhone SE, including the ability to hear either ringing of the number called, or the subsequent audio. On two occasions Resound reps have said the iPhone SE is incompatible, which ignores the fact that the App & SE have otherwise been compatible for several years.

Any time I intend to make a phone call, it usually requires going back to settings to confirm that level of Bluetooth connectivity; most often there is. Next, I need to confirm the connection status in the SMART app. (Anytime the Smart app is no longer the active window, connectivity is lost.) As a result, a “pause” is necessary while SMART app re-connects, which takes from several seconds, or it may “hang” & require closing & re-launching the SMART app, which increasingly doesn’t work, even though Settings indicates an iPhone Bluetooth connection. On occasion, even though Settings & the SMART app indicate connection, there is no audible ringing, or speech. The Client is out of communication until inexplicably, a haphazard application executes, but with no notice.
