Hi Ducati23,
For help with your Bluetooth connection with your hearing aid, be sure your device is paired using the steps below found in the article here: Use hearing devices with iPhone
"Pair a hearing device with iPhone
If your hearing devices aren’t listed in Settings > Accessibility > Hearing Devices, you need to pair them with iPhone.
- Open the battery doors on your hearing devices.
- On iPhone, go to Settings > Bluetooth, then make sure Bluetooth is turned on.
- Go to Settings > Accessibility > Hearing Devices.
- Close the battery doors on your hearing devices.
- When their names appear below MFi Hearing Devices (this could take a minute), tap the names and respond to the pairing requests.
Pairing can take as long as 60 seconds—don’t try to stream audio or otherwise use the hearing devices until pairing is finished. When pairing is finished, you hear a series of beeps and a tone, and a checkmark appears next to the hearing devices in the Devices list.
You need to pair your devices only once (and your audiologist might do it for you). After that, your hearing devices automatically reconnect to iPhone whenever they turn on."
If the issue continues adjust the settings and use the section "Turn on Hearing Aid Compatibility" found in the same article to assist.
