If you have Made for iPhone hearing aids, you can use iPod touch to adjust their settings, stream audio, or use iPod touch as a remote mic.
Pair with iPod touch. If your hearing aids aren’t listed in Settings > General > Accessibility > Hearing Devices, you need to pair them with iPod touch. To start, open the battery door on each hearing aid. Next, on iPod touch, go to Settings > Bluetooth, and make sure Bluetooth is turned on. Then, go to Settings > General > Accessibility > Hearing Devices. Close the battery doors on your hearing aids and wait until their name appears in the list of devices (this could take a minute). When the name appears, tap it and respond to the pairing request.
When pairing is finished, you hear a series of beeps and a tone, and a checkmark appears next to the hearing aids in the Devices list. Pairing can take as long as 60 seconds—don’t try to stream audio or otherwise use the hearing aids until pairing is finished.
You should only need to pair once (and your audiologist might do it for you). After that, each time you turn your hearing aids back on, they reconnect to iPod touch.
Turn on Hearing Aid Mode. Hearing Aid Mode may reduce interference with some hearing aid models. To turn it on, go to Settings > General > Accessibility > Hearing Devices.
Adjust hearing aid settings and view status. Go to Settings > General > Accessibility > Hearing Devices, or choose Hearing Devices in Accessibility Shortcut. Hearing aid settings appear only after you pair your hearing aids with iPod touch.
To access shortcuts from the Lock screen, go to Settings > General > Accessibility > Hearing Devices, then turn on Control on Lock Screen. From the Lock screen, you can:
Check hearing aid battery status.
Adjust ambient microphone volume and equalization.
Choose which hearing aids (left, right, or both) receive streaming audio.
Control Live Listen.
Stream audio to your hearing aids. To stream audio from Siri, Music, Videos, and more, see Bluetooth devices.
Use iPod touch as a remote microphone. You can use Live Listen to stream sound from the microphone in iPod touch to your hearing aids. This can help you hear better in some situations—for example, when having a conversation in a noisy environment. Triple-click the Home button, choose Hearing Devices, tap Start Live Listen, then position iPod touch near the sound source.
Use your hearing aids with more than one iOS device. If you pair your hearing aids with more than one iOS device (both iPhone and iPod touch, for example), the connection for your hearing aids 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 aid settings on one device are automatically sent to your other iOS devices. To enable this feature, sign in to iCloud using the same Apple ID on all the devices, and connect all the devices to the same Wi-Fi network.
