How can I use iPhone as a listening device

Hello petithair73,

We understand you want to know how to use our iPhone as a listening device. We're here to help.

If you're looking to use the Made for iPhone hearing devices then follow the steps below for help on to set that up.

"Pair and connect

When you pair a Made for iPhone hearing device to your Apple device, audio from your Apple device goes to your hearing device. If you turn off your hearing device, you need to reconnect it when you want to use it with your Apple device again.

To pair your hearing device, follow these steps:

1. Make sure that Bluetooth is on. Go to Settings, then select Bluetooth.
2. Open the battery doors on your hearing device.
3. On your Apple device, go to Settings > Accessibility > Hearing, and select Hearing Devices.
4. Close the battery doors on your hearing device. Your Apple device will search for your hearing device.
5. 
6. 
   
7. Under MFi Hearing Devices, tap the name of your hearing device.
8. Tap Pair when you see the pairing request on the screen. If you have two hearing devices, you'll get two requests. Pairing could take up to a minute.
9. 

You can start using your hearing device when you see it under MFi Hearing Devices with a check mark. Control on Lock Screen will be on. Leave it on to control your hearing device from the Lock screen (using the Accessibility Shortcut) and from Control Center on your iPhone or iPod touch, or Control Center on your iPad.

Pair with more than one device

When you pair your hearing devices with more than one Apple device, the connection for your hearing devices switches from one device to the other when you use audio. The connection also switches when you receive a call on your iPhone. If you make changes to your hearing device settings on one device, they're sent to your other devices. 

To pair with another iPhone, iPad, or iPod touch, follow these steps:

1. Make sure all devices are connected to the same Wi-Fi network and signed in to iCloud with the same Apple ID.
2. Follow the steps for how to pair your hearing device.

Connect when you turn on your hearing device

When you turn off your hearing device, it disconnects from your device. When you turn on your hearing device, open and close the battery doors on your hearing device to connect again."
