Amazing hearing aids and app

I am using this app with Costco's Signature 8.0 hearing aids. I was blown away by my iTunes streaming music directly to my hearing aids directly from my iPhone 7+. The sound clarity and bass is hard to believe when you first hear it. You can even use iOS’ sound equalizer to output sound tuned to your particular preference. I have this app and the hearing aids enabled on both my iPhone and my iPad, and I can move back-and-forth between devices simply by disabling Bluetooth on the device I am leaving. The sound is not 100% perfect because sometimes I get crackling and pops in the hearing aids when streaming Music or podcasts– not frequently but often enough that I would like to find the cure. There doesn’t seem to be a pattern for when this occurs. Searching the internet indicates the problem might be with my iPhone 7 Plus – the technology built into this iPhone may not be completely compatible. I was using Google Maps the other day and was surprised to hear the GPS directions coming in over my hearing aids. It’s also nice to control music or podcast volume using the iPhone’s volume controls, and you can even use iOS to change the sound output balance when needed from center weighted to heavy in the left or right hearing aid. I am almost deaf in my right ear in certain tones and the ability to hear clearly is amazing. Last night I was hearing birds chirping in nearby trees which I’ve never heard before.

Terrible App

I’ve had my hearing aids for two months. Bought them from Costco. Hearings aids work fine in spite of this app. Three times now I’ve had to go back to Costco with problems. The app is initially in demo mode. Costco personnel paired my hearing aids to the app. Three weeks later it was back in demo mode. They blamed the Apple update so they repaired them for me. I tried before I went to Costco but had no luck. I didn’t know and didn’t fine in instructions to turn demo off at the bottom. So now the hearing aids were paired. But two days later they were back in demo mode and there was no Apple update to cause the problem. So I have to repair them if I can. Other problems I’ve encountered in the two months I’ve owned them include left hearing aid cutting in and out, problems with Bluetooth connectivity in my 2017 Cadillac, and people complaint they can’t hear me when I’m talking on the phone with the hearing aids connected to the phones speaker. I’m ready to give up and return the hearing aids to Costco under there 180 day policy. Someone needs to fix this app, most of the reviews are terrible. I wonder if Costco is reading these reviews.I can’t believe they’d let this continue. Fix the app please.

Very useful app

I am using the KS ver. 8 hearing aids since mid-November. I have been using aids for over 9 years and these are my 2nd set (my 1st set were Rexton and cost double what these cost. The new features are great; especially the Bluetooth.
I have had very little issue with these aids and this app has made my experience even better. I have had none of the connectivity issues others have reported. The app automatically lets my car system take priority (Ford Sync) when I am in the car.

I have had no issues with it working with my iPhone 6 either. The leave the app open in the background, which eliminates the time it takes to open, with very little impact on my iPhone battery’s charge.
The streaming option with this app, especially using the optional TV streamer, is fantastic. No need to use those “TV Ears” headphones that so many people I know use.
