Connecting hearing aids to an iPhone is usually easy once you know which pairing method your hearing aids use.
Made for iPhone (MFi) hearing aids are normally paired through:
Settings > Accessibility > Hearing Devices
Some other models, including many Phonak hearing aids, use the regular:
Settings > Bluetooth
That distinction matters because a hearing aid can be perfectly compatible with iPhone and still never appear under MFi Hearing Devices.
Check Which Type of Hearing Aid You Have
Before changing settings, identify the connection type.
Made for iPhone hearing aids
These usually connect through:
Settings > Accessibility > Hearing Devices
Apple maintains a current list of compatible MFi hearing devices.
Standard Bluetooth hearing aids
Some hearing aids pair for calls and media through:
Settings > Bluetooth
Phonak is a common example. Current Phonak instructions direct users to the normal Bluetooth screen for phone calls and media streaming.
If you are unsure, check the hearing-aid model or manufacturer instructions before troubleshooting the wrong menu.
1. Charge Both Hearing Aids First
Make sure both hearing aids have enough power before pairing.
For rechargeable models:
- charge them first
- remove them from the charger when ready to pair
For replaceable-battery models:
- use good batteries
- close the battery doors securely
Low battery can stop a hearing aid from entering pairing mode or cause it to disappear during setup.
2. Keep the Hearing Aids Close to the iPhone
Place the hearing aids close to the iPhone during the first pairing attempt.
Also move or temporarily disconnect nearby devices that may already know the hearing aids, such as:
- another iPhone
- iPad
- Mac
- Android phone
- tablet
Apple specifically recommends turning Bluetooth off temporarily on another nearby device if the hearing aids are already paired to it.
That prevents them from reconnecting somewhere else while your iPhone is trying to discover them.
3. Turn Bluetooth On
Open:
Settings > Bluetooth
Turn Bluetooth on.
For troubleshooting, use the Bluetooth switch inside Settings instead of relying only on Control Center.
4. Open Hearing Devices for MFi Models
For Made for iPhone hearing aids, go to:
Settings > Accessibility > Hearing Devices
Look for the MFi Hearing Devices section.
If the hearing aids are already paired, their name may appear here.
If they are not listed, put them into pairing mode.
5. Put the Hearing Aids Into Pairing Mode
Apple’s general instruction for MFi devices is to turn the hearing aids off and back on again.
For models with replaceable batteries, this often means:
- Open the battery doors.
- Wait a few seconds.
- Close them again.
For rechargeable hearing aids, pairing mode may begin after:
- placing them in the charger and removing them
- turning them off and back on with the device button
- following the manufacturer’s restart procedure
The exact method varies by brand and model, so use the manufacturer’s instructions if a normal restart does not make the device discoverable.
6. Tap the Hearing Aid Name
Stay on:
Settings > Accessibility > Hearing Devices
Wait for the hearing aid name to appear under MFi Hearing Devices.
Apple says discovery can take up to about a minute.
Tap the hearing-aid name when it appears.
7. Accept the Pairing Request
Tap Pair when the Bluetooth pairing request appears.
When using two hearing aids, iPhone may ask you to approve more than one pairing request.
Accept each request and wait until pairing is complete.
Apple says the process can take up to about 60 seconds, so avoid trying to stream audio before the pairing finishes.
Once pairing is complete, the hearing aids should normally reconnect automatically when they are turned on and near the iPhone.
8. Test Calls and Media
Play a song, podcast, or video, then make a test call.
If sound still comes from the iPhone speaker, open Control Center and check the current audio output.
Choose the hearing device when necessary.
For phone calls, pay attention to where call audio is routed.
If the iPhone has a broader call-audio problem even when the hearing aids are disconnected, see iPhone Speaker Not Working During Calls.
Do not repeatedly pair and unpair hearing aids when the real problem is audio routing.
Control MFi Hearing Aids From iPhone
Once connected, open:
Settings > Accessibility > Hearing Devices
Tap the connected hearing device.
Depending on the model, iPhone can expose controls for:
- battery status
- microphone level
- audio routing
- left and right balance
- presets
- Live Listen
- ringtone streaming
You can also add hearing controls to Control Center.
This is useful for checking battery status or switching supported hearing functions without opening Settings every time.
How to Pair Phonak Hearing Aids to iPhone
Many Phonak hearing aids use standard Bluetooth pairing for calls and media instead of Apple’s MFi Hearing Devices menu.
Open:
Settings > Bluetooth
Then:
- Make sure Bluetooth is on.
- Restart the hearing aids to enter pairing mode.
- Wait for the hearing-aid name to appear.
- Tap the device name.
- Wait for the confirmation tone.
Current Phonak instructions say the name may appear as something similar to:
R-Phonak hearing aid
or:
L-Phonak hearing aid
depending on the configuration.
For rechargeable Phonak devices, pairing mode can often be started by placing the devices in the charger briefly and removing them.
For battery-powered models, opening the battery doors for several seconds and closing them can start pairing mode.
Some newer Phonak models can also set up streaming automatically during myPhonak app pairing, while older generations may require a separate call-and-media pairing step.
Hearing Aids Do Not Appear on iPhone
Start with pairing mode.
Most hearing aids are discoverable only for a limited period after restarting.
Try this:
- Keep the hearing aids next to the iPhone.
- Turn Bluetooth off and back on from Settings.
- Restart both hearing aids.
- Return to the correct pairing screen.
- Wait up to a minute.
For MFi hearing aids, use:
Settings > Accessibility > Hearing Devices
For standard Bluetooth hearing aids, use:
Settings > Bluetooth
Also turn Bluetooth off temporarily on nearby devices that have previously paired with the hearing aids.
Only One Hearing Aid Connects
When only one side connects:
- Check battery or charge on both hearing aids.
- Restart both devices at the same time.
- Keep both next to the iPhone.
- Start pairing again.
- Accept every pairing request.
When using MFi hearing aids, iPhone may issue separate pairing requests for the left and right devices.
Do not approve the first request and immediately close Settings.
If one hearing aid repeatedly fails to connect even with another compatible phone, the problem may be with that hearing aid rather than the iPhone.
Hearing Aids Are Connected but There Is No Sound
A connected status does not always mean audio is currently routed to the hearing aids.
Play audio, then open Control Center and check the playback destination.
Select the hearing aids if necessary.
Also test:
- music
- phone call
- video
- Siri
If calls work but music does not, or music works but calls do not, the hearing aids may use different Bluetooth profiles or audio-routing settings.
Do not assume pairing has failed until you check the current audio output.
Hearing Aids Keep Disconnecting
Common causes include:
- low hearing-aid battery
- another paired device taking the connection
- iPhone too far away
- outdated iOS
- hearing-aid firmware issue
- manufacturer app problem
Try this order:
- Fully charge both hearing aids.
- Restart the iPhone.
- Restart the hearing aids.
- Move other paired devices away.
- Update iOS.
- Update the manufacturer’s hearing-aid app.
- Check for hearing-aid firmware updates.
Avoid resetting all iPhone network settings as the first response to one Bluetooth problem.
Forget and Re-Pair Only When Necessary
For MFi hearing aids:
Settings > Accessibility > Hearing Devices
Tap the hearing-device name and use the available option to forget or unpair it.
Then restart the iPhone and hearing aids before pairing again.
For standard Bluetooth devices:
Settings > Bluetooth > info button beside the hearing aid > Forget This Device
Then restart the hearing aids and pair again.
Re-pairing is most useful when a previously working connection has become corrupted. It should not be the first response every time audio stops routing correctly.
Moving Hearing Aids to a New iPhone
When switching to a new iPhone:
- Turn Bluetooth off on the old iPhone.
- Turn Bluetooth on on the new iPhone.
- Restart the hearing aids into pairing mode.
- Pair them through the correct menu.
For MFi devices:
Settings > Accessibility > Hearing Devices
For standard Bluetooth devices:
Settings > Bluetooth
Once the new iPhone is working correctly, remove stale pairings from the old phone if you no longer need them.
Use Live Listen With Compatible MFi Hearing Aids
Live Listen turns the iPhone into a remote microphone.
To use it:
- Make sure the MFi hearing aids are connected.
- Open Settings > Accessibility > Hearing Devices.
- Tap the hearing-device name.
- Tap Start Live Listen.
- Place the iPhone near the person or sound you want to hear.
This can be useful in noisy environments or when the speaker is farther away.
Apple also allows Live Listen access through hearing controls and accessibility shortcuts on supported setups.
Update iOS Before Deeper Troubleshooting
Open:
Settings > General > Software Update
Install a current compatible iOS update when one is available.
Bluetooth and accessibility behavior can change across iOS versions, and hearing-device support is actively maintained by Apple.
Restart after updating, then test the existing connection before deleting pairings.
Do Not Factory Reset Hearing Aids Without Guidance
Restarting hearing aids for pairing mode is normal.
A full factory reset is different.
It may affect:
- professional fitting
- stored programs
- pairing information
- custom settings
Do not factory-reset professionally fitted hearing aids unless the manufacturer or your hearing-care provider specifically instructs you to do so.
When to Contact the Hearing-Care Provider
Contact the audiologist, hearing-care provider, or manufacturer when:
- one hearing aid never enters pairing mode
- one side repeatedly disconnects
- the hearing aids are not detected by any compatible phone
- firmware needs professional service
- pairing behavior changed after professional programming
- you are unsure whether the model supports MFi or standard Bluetooth streaming
The key is to use the pairing method designed for the hearing aid. MFi models belong in Accessibility > Hearing Devices, while some other hearing aids belong in the regular Bluetooth menu. Once that distinction is correct, most connection problems become much easier to diagnose.
