Tips for improvements

First of all, the most recent update which provides an optimized connection to the phone is great. It connects much faster. Kudos! However, this causes the watch app to be even more reliable than it previously was. This feature would be even more appreciated if it didn’t degrade the experience in the watch app. Please test and fix the watch integration. I would like to make more use of it, but it needs to be improved in terms of performance. The features are there and are appreciated when it actually connects to the phone.

Second, please test the heating aid experience with AirPods. No matter what the settings are, the hearing aids want to take the call. They usually work OK, but try switching to another Bluetooth device like AirPods. It rarely works and if it does, it won’t last. I prefer the sound quality of the AirPods to the hearing aids. The call sound quality is pretty poor in comparison to AirPods or even plain old wired EarPods.

Please pay attention to some of these other use cases in testing. I know that in some cases, it may be something that you need to work on with Apple because you need changed in the OS, but you have a decent app that could be vastly better overall.

As I’ve said in the past, let me know if you need a beta tester. :-)

Thank you for listening!

App’s not ready for prime time

Every time I open the app, it has to reconnect to the hearing aids. Often times, that doesn’t work, and I need to restart the app. The connection to the Apple Watch is useless. Even when I launch the app first on my phone and have my phone right next to the watch, I rarely can connect. Defeats the purpose of the desire to discretely adjust settings when in public. The hearing aids hijack my hands-free system in my car, too. ReSound’s customer service is sorely lacking. My audiologist told me to call ReSound with my questions; the person who handled my call told me to talk to my audiologist or the Apple store (talk about a runaround). I then tried to reach ReSound through their Facebook page, and they didn’t even respond. The Apple store tried to help, but were not able to improve on any of the challenges I experience with this app. My audiologist bragged how ReSound hired Genius Bar employees to make this app; well, I think they picked up some “geniuses” at some “bar” who had had a few too many. Seriously, not everyone who wears hearing aids is a 85 year old with few technological expectations. If you’re going to promote a hearing app that’s specifically designed for an iPhone, make sure it’s going to perform as promised.

I am sorry to hear what you have experienced.
We are aware of an issue with the Bluetooth connection and latest iOS, we are therefore looking into the coding in the app in order to improve the connections.

Best regards

I bought these particular hearing aids based on the sales pitch my audiologist gave me. I was impressed with what I was told they were capable of doing: automatically connecting to my phone giving me discreet ability to control settings, changing between iPhone and iPad without glitches, and the watch!!! Wow! The watch was the “Sign me up moment!” HOWEVER... Nothing promised was delivered! Connecting to my iPhone is hit and miss, even after purchasing a new phone. I’m constantly having to reboot while crossing my fingers the 2nd, 3rd, 4th time before finally having to sometimes just give up. Switching between iPhone and iPad is just as difficult so I don’t bother even having the app on my iPad. And the watch!!! Really!!! This was the selling point for me. Of course once I realized this was an issue on ReSounds end, my trial period was up. I was looking forward to going on runs while wearing my hearing aids, but this isn’t happening. I wish I would have read these reviews and did more research before buying these hearing aids. I do regret this very expensive out of pocket expense and recommend to everyone to do their research before making this purchase.
