A practical guide you can follow at home.


Bluetooth streaming in hearing aids is incredibly useful — until it suddenly isn’t. If your hearing aids won’t connect to your phone, only stream to one ear, or the app won’t open or respond, you’re not doing anything wrong. These issues are common and usually related to Bluetooth itself rather than the hearing aids.The good news is that most Bluetooth problems can be fixed in a few simple steps. This guide explains what’s going on and walks you through the most reliable ways to reconnect your hearing aids to your phone.

Why Bluetooth Hearing Aids Sometimes Stop Working

Bluetooth connections are controlled largely by your phone’s operating system, not just the hearing aids.


On iPhones, the connection for Made for iPhone hearing aids is managed by Apple. When Apple releases software updates, Bluetooth connections can occasionally become unstable until hearing aid apps or firmware are updated to match.


Android phones can experience similar issues, particularly after system updates.

This doesn’t mean:

  • Your hearing aids are faulty

  • Your phone is broken

  • Your audiologist has done something wrong

It’s simply how Bluetooth technology behaves.


Common Bluetooth Problems and What to Do

Streaming only to one hearing aid

This is often caused by the phone’s position. Your body can block the Bluetooth signal.

Try this first

  • Move your phone to a different pocket or hand

If that doesn’t help:

  1. Turn Bluetooth off, wait 30 seconds, then turn it back on

  2. Turn your hearing aids off and on

If the issue continues, follow the re-pairing steps later in this guide.

The hearing aid app won’t connect

This usually means the phone and hearing aids have lost synchronisation.

Try this order

  1. Restart your hearing aids

  2. Turn Bluetooth off and on

  3. Close and reopen the app

If it still won’t connect, forgetting and re-pairing the devices usually resolves it.


Always Check for Updates First

Before trying anything else, make sure your phone and hearing aid app are up to date.

Update your phone software

On iPhone

  1. Go to Settings

  2. Tap General

  3. Tap Software Update

  4. Install any available updates

On Android

  1. Open Settings

  2. Tap Software Update or Security

  3. Follow the on-screen instructions

Update your hearing aid app

On iPhone

  1. Open the App Store

  2. Tap your profile icon

  3. Scroll to see pending updates and tap Update

On Android

  1. Open Google Play Store

  2. Tap your profile icon

  3. Select Manage apps & device

  4. Tap Update

Turn Bluetooth Off and On

This simple step fixes many Bluetooth issues.

  1. Open Settings

  2. Go to Bluetooth

  3. Turn Bluetooth off

  4. Wait 30–60 seconds

  5. Turn Bluetooth back on

Try streaming or opening the app again.


Forget and Re-Pair Your Hearing Aids (Most Reliable Fix)

If problems continue, this is usually the solution.

Step 1: Forget the hearing aids

  1. Go to Settings > Bluetooth

  2. Find your hearing aids in the list

  3. Tap the information icon

  4. Select Forget This Device

Some hearing aid apps also allow you to forget devices within the app.

Step 2: Restart your phone

Turn your phone off completely, then back on.

Step 3: Re-pair the hearing aids.


Pairing Hearing Aids to an iPhone

  1. Open the battery doors or place rechargeable hearing aids in the charger

  2. On your iPhone, go to Settings > Accessibility > Hearing Devices

  3. Make sure Bluetooth is on

  4. Close the battery doors or remove aids from the charger

  5. Tap the hearing aid name when it appears

  6. Tap Pair (you may see two pairing requests — accept both)

Once paired, your hearing aids will appear with a checkmark.


Pairing Hearing Aids to an Android Phone

  1. Open Settings

  2. Tap Connections or Bluetooth

  3. Turn Bluetooth on

  4. Open battery doors for 5 seconds, then close them

    • Rechargeable aids: place in charger for 5 seconds, then remove

  5. Scan for available devices if needed

  6. Select your hearing aids from the list

  7. Confirm pairing

You should hear a confirmation tone in the hearing aids.


Hearing aids from Phonak and Unitron work slightly differently.

  • Both hearing aids pair with the app

  • Only the right hearing aid pairs for phone call streaming

This is normal and not a fault.


When Deleting and Reinstalling the App Helps

If nothing else works:

  1. Forget the hearing aids

  2. Delete the hearing aid app

  3. Restart your phone

  4. Reinstall the app

  5. Re-pair the hearing aids

This is usually the final step before contacting your audiologist.


When to Contact Your Audiologist

If you’ve:

  • Updated everything

  • Restarted devices

  • Forgotten and re-paired

  • Reinstalled the app

…and the problem continues, your audiologist can check for firmware updates or other issues.


Bluetooth Can Be Frustrating — But It’s Still Worth Using

Bluetooth isn’t perfect, but it allows:

  • Phone calls directly to your hearing aids

  • Music and TV streaming

  • Easy control through apps

For most issues, forgetting the devices, re

starting the phone, and re-pairing solves the problem.


Once you’ve done it once or twice, it becomes much easier.
