Hi skycap,

Re: "this lack of compatibility between Oticon and iPhone really has me stumped as well".
Wondering if your Oticon model is one of those listed as compatible by Apple:
The Made for iPhone (MFi) hearing aids listed in Apple Support's article are compatible with iPhone and iPad. (Those marked with an asterisk (*) are also compatible with Mac.): List of Made for iPhone hearing devices - Apple Support

Re: "I can be listening on my iPhone - loose the audio and then find that the Oticons have paired with my iPad without reason"
You may want to check with your hearing-specialist or the hearing-aid manufacturer (Eg: contact "support" on their website) for a possible hearing-aid firmware update, or, if you use an app, check for an app update.
______
Else: Use Made for iPhone hearing devices - Apple Support
says (amongst many other things):
"Hearing device disconnects unexpectedly
- When using your hearing device, make sure that your paired Apple device remains nearby.
- If your hearing device is paired with more than one Apple device, it might switch (hand off) to the other Apple device when it detects an incoming call on that device, or when you start playing audio on the other device. You can control this by changing the Audio Handoff setting in Hearing Devices settings on your iPhone or iPad.
- Check the battery level of your hearing device. You might need to replace or recharge the batteries.
- Check for wireless interference."

More info. on Hand off tasks between iPhone and your other devices - Apple Support. Eg: says:

"Hand off from another device to your iPhone

"Hand off from iPhone to another device
On the other device, click or tap the Handoff icon to continue working in the app.
The Handoff icon of the app you’re using on iPhone appears in the following locations on other devices:
- Mac: The right end of the Dock (or at the bottom, depending on the Dock position).
- iPad: The right end of the Dock.
- iPhone or iPod touch: At the bottom of the App Switcher screen."
All the best :-)
