Hello troublescookin,
To help us get a better understanding of the issue, we’d like to ask a few questions.
When this happens does the hearing device seem to switch to another device? If so, please check out the information from the following link, which may help: Use hearing devices with iPhone
Use your hearing devices with more than one device
If you pair your hearing devices with more than one device (both iPhone and iPad, for example), the connection for your hearing devices automatically switches from one to the other when you do something that generates audio on the other device, or when you receive a phone call on iPhone.
Changes you make to hearing device settings on one device are automatically sent to your other devices.
1. Sign in with your Apple ID on all the devices.
2. Connect all the devices to the same Wi-Fi network.
If you need additional assistance, please contact Apple Support for help. You may be able to reach them here: Contact Apple Support
Thank you.
