### 1/5 — Still pairing issues with Audiokey 2.0

*2024-09-24*

The app is still very 50/50 if it will pair to stream music or not. Have to go through the configuration process over and over.  Irritating.  

Also, why doesn’t the app allow the user to mute environmental noise when streaming music?  I think an early version of the app did so.  Why did was that feature removed?

**Developer response:** Dear 'jsteffe13', thanks for your review. Whether it is possible to stream only audio (exclude the processor microphones during streaming) depends on the type of audio processor you are using. Also, your AudioStream interacts directly with the operating system of your phone, once configured via the app. In order to improve the overall stability of the connection of your AudioStream, you can update the AudioStream firmware via the AudioKey 2 app. In order to do that, the AudioStream needs to be unparied from your phone first. Please send an email to us at audiokey@medel.com for further instructions on how to update your AudioStream. Thanks.

### 2/5 — Rubbish

*2024-06-07*

Rather rubbish app which does not update. Let me explain. CI is switched on 4 weeks ago and I use 2 programs which this app did. Yesterday my CI was updated to 4 programs. Tried disconnecting and reconnecting but it still only shows 2 programs. This app is more hassle than it is worth. There is a Scottish word for such a thing but best not to mention it!! Get it sorted! Get a ‘update CI settings on the menu’.

**Developer response:** Dear FEMSW, thanks for your review. Our app already has a feature that allows you to refresh the audio processor data (e.g., after a fitting appointment). Please open the User Profile of the app (your name in the main menu), tap on the three dots in the upper right corner and select 'Refresh audio processor data'. Once the refresh process is completed, you will see all 4 programs in the Listening Settings of the app. In case you have further questions or suggestions, please send an email to us at audiokey@medel.com. Thanks.

### 1/5 — useless app

*2023-12-21*

in may, i got bluetooth for my hearing aids and used this app. for about a month it was fine until one day it just stopped working. i've deleted the app and reinstalled yet it still doesn't work. what happened?? i've had to go back to my wired headphones that plug into my hearing aids but they're low quality.

**Developer response:** Dear "soopgull", thanks for your review. We are sorry to hear that you are experiening issues with streaming and would like to invite you to send an email to us at audiokey@medel.com.

### 2/5 — Battery

*2023-10-14*

There is no way to see the Battery life I’m on my Sonnet 2

**Developer response:** Dear 'kachunter', thanks for your review. Unfortunately, due to hardware limitations, the SONNET 2 battery status cannot be displayed in the AudioKey 2 app (this feature is currently only available for the RONDO 3 audio processor). However, we will consider your suggestion for improvement for the future development of our app and our audio processors. If you have further questions or suggestions, please send an email to us at audiokey@medel.com. Thank you.

### 1/5 — Poor programming

*2023-09-21*

It’s very difficult to connect to AudioStream because it mainly won’t connect at all. So got tired of constant disconnecting and restarting. Won’t connect.

**Developer response:** Dear 'Waterloo guy', thanks for your review. Could you please send an email to us at audiokey@medel.com, indicating which MED-EL audio processor and which Apple device you are using AudioStream with? We will do our best to help you find a solution to your problem as fast as possible. Thanks.

### 3/5 — Bluetooth for my hear aid

*2023-08-14*

For first few months my hear aid connect to Bluetooth and it been rlly amazing like listening to music etc till got to the point, it don’t work anymore, I reset everything, check all update, it won’t connect and am not too happy about it

**Developer response:** Dear 'Hell-Prodigy', thanks for your review. Could you please send an email to us at audiokey@medel.com, indicating which audio processor and which Apple device you're using? Will will do our best to help you find a solution to your problem. Thanks.

### 2/5 — Kinda works

*2023-02-17*

I use both rondo 3 and sonnet devices. I can add them both in this app, but I can only change programs on whichever device was added to the app last. In order to modify the first device, I have to remove the second device. No small feat as it often takes several attempts to connect a new device. Spend some money and work on improving the app!

**Developer response:** Dear 'carrboropaul', thanks for your review. You can switch in between processors of the same ear side without removing any of them from the app. Please open the 'User Profile' in the app, tap on the 'three-dot' menu in the upper right corner and select 'Switch audio processor'. Now, simply select the processor you would like to use and tap on 'Save'. Once this is done, the 'Listening Settings' will connect to the selected processor and allow you to control it. If you need further assistance, please send an email to us at audiokey@medel.com and we will be happy to help. Thanks.

### 5/5 — Not bad

*2023-02-12*

Been using this instead of my fine tuner Echo and it does the job perfectly. 
Shame it’s hard to see - needs a dark mode

**Developer response:** Dear "Tazz2011", thanks for your positive review. We are glad to hear that you are happy with our app and we will consider your suggestion for improvement regarding dark mode for the future development of our app. In case you have further questions or suggestions, please send an email to us at audiokey@medel.com. Thanks.

### 4/5 — Feedback

*2022-10-11*

I really appreciate the user interface that allows you the flexibility and convenience in modifying your cochlear implant setting seamlessly. In addition, my favorite feature is the ability to “turn off” my cochlear implant by pressing the mute button in the monitoring mode. I don’t have to physically take it off! Now there is some feature I wish could be implemented in the app. For instance, I believe it will serve all the app users if the battery usage is showed on the app indicating low battery instead of beeping noise inside our cochlear implant. Growing up, that beeping noise always bothered me. That would be an extremely significant feature imho. Overall, excited for updates in the future! Keep it up! 💪

**Developer response:** Dear 'Umar1990876', thanks for your review. We are glad to hear that you are happy with our app and will consider your suggestions for the future development of our app and audio processors. In case you have further questions or suggestions, please send an email to us at audiokey@medel.com. Thanks.

### 1/5 — Does not work

*2022-09-06*

Will not allow me to connect to my Sonnet processor. Can’t do anything.

Update: developer says Sonnet cannot connect to the app via Bluetooth Low Energy, but can do so via Audiolink. My response— no it can’t. I’ve tried multiple times and it says “Audio processor not configured for use with AudioKey 2.” Why market an app for use with Sonnet if it’s not compatible?

**Developer response:** ORIGINAL REPLY: Dear 'Willy Bob Joe', thanks for your review. Due to technical limitations, older generations of audio processors (such as SONNET) cannot be paired to our app directy via Bluetooth Low Energy. However, they can still be paired to the app via AudioLink. Please send an email to us at audiokey@medel.com and we'll be happy to provide further information or instructions. Thanks.
UPDATED REPLY: Dear 'Willy Bob Joe', thanks for the update of your review. The error message points to the fact, that your audiologist configured your SONNET for the use with the 'FineTuner' remote control. However, in order to be used with the AudioKey 2 app, your SONNET needs to be configured for the use with 'FineTuner Echo and AudioKey'. Please get in touch with your audiologist so that your SONNET can be reprogrammed with the corresponding settings. Once that is done, you will be able to pair your SONNET to the app via AudioLink. Please send an email to us at audiokey@medel.com if you require further information. Thanks.
