Hi there! I understand how important a stable connection to your hearing aids is, and I'm here to help you resolve this. Let's start by confirming a few details to better understand the situation:

1. How long have you been experiencing this issue with the Oticon Companion app losing connection?
2. Have you tried any specific troubleshooting steps so far? For example, restarting your phone or the hearing aids?

Once I have a bit more context, I can guide you through some potential solutions!

Never been right. New hearing aids. I have rebooted and reinstalled everything

Thanks for the additional details! Since you've already rebooted and reinstalled everything, let's try a few more steps to establish a more stable connection between your Oticon Companion app and your hearing aids.

### Step-by-Step Solution:

1. Forget and Re-pair the Hearing Aids:
- Go to your iPhone's Settings > Bluetooth.
- Look for your hearing aids in the list of connected devices and tap the "i" icon next to them.
- Select Forget This Device. This will remove the hearing aids from your iPhone’s Bluetooth list.
- Now, go back to the Oticon Companion app and follow the prompts to pair your hearing aids again.

2. Clear Old Bluetooth Connections on Hearing Aids:
- Sometimes, old connections can interfere. You can usually do this by following the manufacturer's instructions, often found in the hearing aid’s manual.
- If you're unsure how to do this, please let me know, and I can help guide you.

3. Check for Firmware Updates:
- Ensure that your hearing aids are updated to the latest firmware. Sometimes, older firmware can cause connectivity issues.
- You can check this through the Oticon Companion app, as it should notify you if updates are available.

4. Check iPhone Permissions:
- Go to your iPhone's Settings > Privacy > Bluetooth.
- Ensure that the Oticon Companion app is allowed access to Bluetooth.

5. Toggle Bluetooth and Restart:
- Turn off Bluetooth on your iPhone, wait about 30 seconds, then turn Bluetooth back on again.
- Restart your iPhone one more time after that.

If these steps don't resolve the issue, do you notice if the problem happens more in certain environments, like in specific locations or when using other devices? That can help narrow down if it's an interference issue or something else.
