Pair Hearing Aids to iPhone: Steps and Fixes

Open Settings, tap Accessibility, then Hearing Devices. Put both hearing aids in pairing mode, tap Pair MFi Hearing Device, choose yours, and tap Pair. That’s Apple’s route, and it works for Made for iPhone (“MFi”) hearing aids only.

Getting into pairing mode is the step that trips people, because it depends on the model. (More like this lives in our iPhone hearing tools set.)

Pair them from Hearing Devices

Apple’s help page gives the sequence. Here it is in the order I’d do it:

1. Update iOS first. Apple says to, and an old version is a cheap thing to rule out.
2. If the hearing aids are already paired to a nearby iPad or Mac, switch Bluetooth off on those for now. You can turn it back on when you’re done.
3. Put the hearing aids in pairing mode, close to the iPhone. Apple lists the usual three methods. With replaceable batteries, open the battery door on each, then close it when you’re ready. With a power switch, turn them off and on. With built-in rechargeable batteries and no switch, take them off the charger.
4. On the iPhone, go to Settings > Accessibility > Hearing Devices and tap Pair MFi Hearing Device. Apple’s instructions start in Accessibility rather than the general Bluetooth list, so start there.
5. Choose your hearing aids from the list, then tap Pair. You may get a pairing request for each ear. Say yes to every one.
6. Give it a minute to finish before you play anything.

You do this once. After that the hearing aids reconnect to the iPhone whenever they turn on, and your audiologist might have done the first pairing for you already.

Two details Apple mentions that are easy to miss. If you don’t see the Pair MFi Hearing Device button, tap the name of your hearing aids when it shows up under Hearing Devices, then tap Pair on the Bluetooth requests. And if you pair a different hearing device later, the new one replaces the old one.

Once they’re connected, the same screen is where the controls live. Tap the name of your hearing aids to reach microphone volume and audio presets. Apple’s iPhone guide also shows how to put a Hearing control in Control Center and on the Lock Screen, which is faster than digging through Settings each time. For the remote-microphone trick, see our guide to Live Listen on iPhone.

What I could and couldn’t check. I read Apple’s iPhone User Guide page “Use hearing devices with iPhone” (iOS 27), Apple’s support article “Use Made for iPhone hearing devices” (published September 14, 2026), and Apple’s list of Made for iPhone hearing devices, all in October 2026. I didn’t pair a hearing aid for this page, so I can’t tell you how any particular model behaves on screen. For anything model-specific, your hearing aid’s manual and its maker’s app are the authority.

iOS version checked: iOS 27, October 2026 (Apple’s documentation, not a phone I used).

Check the asterisk before you count on calls

Pairing and talking are two different things, and this is where the pairing guides I read leave people stuck.

Apple publishes a list of Made for iPhone hearing devices. Some models carry an asterisk. Apple’s note says those models use bidirectional streaming, “which allows you to talk hands-free.” Models without one use unidirectional streaming.

Read that plainly: a hearing aid with no asterisk can pair perfectly, play your music and your podcasts, and still not carry your voice back into a phone call. Nothing is broken. That’s what the model does. In the list as I read it in October 2026, the Audibel “Via AI” carries an asterisk and the “A3i” doesn’t, so the difference shows up inside a single brand, not just between them.

If calls matter to you, look up your exact model, not just the brand, and look for the asterisk. Do it before you buy, not after. Pairing steps are the same either way, which is exactly why the missing asterisk gets mistaken for a pairing fault.

If you don’t own hearing aids yet, two things before you shop. The FDA says adults 18 and over who believe they have mild to moderate hearing loss can buy an over-the-counter hearing aid without seeing a doctor first, and that people under 18 or with more severe loss shouldn’t go that route (FDA). It also lists signs that mean seeing a doctor first: an ear deformity or injury, blood, pus or fluid from the ear in the past six months, ear pain, a lot of earwax or something in the ear, dizziness, hearing that changed suddenly or gets worse then better, and loss or ringing in only one ear. I build audio software, not hearing care. The NIDCD’s hearing aid page is a good plain-language place to start.

When your iPhone can’t find your hearing aids

When a hearing device doesn’t appear in Hearing Devices settings, the order of fixes that matters is cheap first. Here’s Apple’s list, in the sequence I’d try it:

• Confirm the model is on Apple’s list. These steps are for Made for iPhone devices only. If yours isn’t on it, the maker’s app and manual are your route, and Apple’s pages don’t go further than that.
• Put it in pairing mode again. Restart both hearing aids and start again from step 3, so you know they’re discoverable.
• Restart the iPhone.
• Unpair it from your other Apple device. If an iPad or Mac still holds the pairing, unpair there, then pair on the iPhone.
• Update the hearing aid firmware. Apple says to make sure it has the latest from the manufacturer, and that the maker’s own app can usually find and install updates.

If the name shows up but it’s dimmed, Apple’s advice is to make sure the hearing aids are near the iPhone, then unpair and pair again. To unpair, tap the name under Hearing Devices and choose Forget this device. The hearing aids won’t reconnect until you pair them again, which is the point.

When they connect, then drop out or go silent

These are two separate symptoms, and the fixes are boring on purpose.

Disconnecting. Keep the iPhone nearby, check the hearing aids’ battery level, and rule out wireless interference. If they’re paired to more than one Apple device, they may switch to the other one when it detects an incoming call or starts playing audio. You control that with the Handoff setting in Hearing Devices.

Connected but silent. Pick your hearing aids as the sound output, the same way you’d choose a speaker with AirPlay, and check the microphone level in Hearing Devices settings. Calls, music, movies, podcasts and Siri can all stream this way.

The same screen has a Hearing Aid Compatibility switch that may reduce interference and improve audio quality with some models. Ratings aren’t a guarantee, though: a given hearing aid can work well or badly with a given phone, so try the two together before you buy (Apple’s guide has the full wording, and Apple’s HAC page lists iPhone ratings). What the switch actually does, and who should turn it on, is in our guide to iPhone hearing aid compatibility.

If you also own an iPad or a Mac

You can pair the same hearing aids to several Apple devices. The connection then follows the sound: it moves to whichever device starts playing audio, and it moves to the iPhone when a call comes in. Changes you make to hearing aid settings on one device sync to the others, as long as every device is signed in to the same Apple Account and connected to the same Wi-Fi network. Apple’s instructions cover iPhone, iPad, Mac and Apple Vision Pro. They don’t mention Apple Watch, so I won’t guess whether it connects.

That’s useful, and it’s also the reason hearing aids seem to wander. If yours jump to the iPad while you’re trying to watch something on the iPhone, Handoff is the setting to look at, not the batteries.

For the companion apps hearing aid brands ship, see hearing aid app for iPhone. If you’re curious about the AirPods route instead, our guide to Apple’s Hearing Aid feature covers who it’s for.

If you don’t wear hearing aids

No hearing aids, and a conversation to follow tonight? That’s a different tool.

Clarive is an iPhone app I build. It doesn’t pair with hearing aids, and it isn’t a hearing aid or a replacement for one. What it does is use the iPhone’s microphone to amplify sound and play it through any headphones that connect to your iPhone, including AirPods and wired EarPods, and show live captions on screen. It’s free to download, with a limited free tier. If you already wear hearing aids, this probably isn’t what you need.

Get Clarive on the App Store if that sounds like your situation. If you’re not hearing as well as you used to, tell a doctor or audiologist. An app can’t tell you what’s causing it.
