Phonak Crossfit Compatibility to Mobile Phone: Key Facts and Tips

Phonak CROS systems can connect to compatible Android phones and iPhones for myPhonak control, phone calls, and audio streaming, but pairing may need to be rebuilt after a phone operating-system or app update. The product name is Phonak CROS, not “Phonak Crossfit.” If the connection suddenly fails, start with simple Bluetooth and device restarts before removing and rebuilding the pairings.

What Phonak CROS Is

Phonak CROS is designed for people with single-sided hearing loss. The CROS-side device picks up sound from the poorer or non-hearing side and sends it wirelessly to a compatible Phonak hearing aid worn on the better-hearing side.

For example, Phonak CROS EON works with a compatible Audéo EON hearing aid. Phonak also supports myPhonak with CROS generations including CROS EON, CROS Infinio, CROS Lumity, and CROS Paradise.

Why Phonak CROS Can Disconnect After Android or iPhone Updates

Phonak states that a connection may sometimes fail after a myPhonak update, smartphone operating-system update, or change to the hearing-aid fitting. In many cases, the stored Bluetooth or app relationship simply needs to be refreshed rather than the CROS system being repaired.

Common symptoms include:

• myPhonak no longer finding one or both devices;
• the phone showing the aids as paired while the app says they are disconnected;
• myPhonak controls working but calls or music not streaming;
• audio connecting to another previously paired phone or tablet;
• the connection dropping shortly after an operating-system update.

Phonak’s current support procedure does not require users to start by entering Android recovery mode or wiping the phone’s cache partition. The safer first approach is to restart the app, Bluetooth, phone, and hearing system and then rebuild the pairings if necessary.

Phonak hearing aids normally remain discoverable for about three minutes after they are restarted, so begin pairing soon after putting the devices into pairing mode.

Check Phone Compatibility First

Before repeatedly resetting Bluetooth, confirm that the phone meets the current myPhonak compatibility requirements.

Phonak’s current U.S. guidance lists myPhonak support for:

Minimum requirements can change as myPhonak is updated, and Phonak’s regional pages may not always be updated at the same time. Check the current compatibility information before replacing a phone solely because of a connection problem.

Check Your CROS Generation

Phonak’s current myPhonak compatibility list includes CROS models from several generations, including:

• CROS EON
• CROS Infinio
• CROS Lumity
• CROS Paradise

The exact Bluetooth setup can differ by generation. This matters because newer Phonak devices can establish call and streaming functions during myPhonak setup, while some older generations require an additional streaming/call pairing.

Try the Quick Bluetooth Fix First

Start with the least disruptive troubleshooting steps. Phonak recommends trying these before deleting the complete setup:

1. Close myPhonak completely and reopen it.
2. Close unnecessary background apps.
3. Turn the phone’s Bluetooth off, wait several seconds, and turn it on again.
4. Restart the CROS system and receiving hearing aid.
5. Restart the phone.
6. Open myPhonak and test the connection again.

If the system reconnects, test three separate functions: myPhonak controls, streamed media, and a phone call. A successful app connection does not always prove that the call/audio streaming connection is also configured correctly.

Re-Pair Phonak CROS on Android and iPhone

If restarting does not help, remove the stale pairing and rebuild it. The exact menu wording varies by phone, but the basic process is similar.

Re-Pairing on Android

1. Open Settings > Bluetooth. On Samsung phones, this is commonly under Settings > Connections > Bluetooth.
2. Find every Bluetooth entry belonging to your Phonak hearing system.
3. Open each entry and choose Unpair or Forget.
4. Open myPhonak.
5. Go to Devices, open the device information area, and use Forget my devices if the option is shown.
6. Restart the hearing aid/CROS system to place it into pairing mode.
7. Return to myPhonak and choose Pair hearing aids.
8. Wait until the expected devices appear before confirming the Bluetooth pairing requests.
9. Complete any additional phone-call or streaming setup shown in the app.

During initial Android setup, myPhonak may request permission to find or connect to nearby devices. Phonak also documents a Location Services requirement during initial setup on some Android configurations. Denying a required permission can prevent discovery.

Re-Pairing on iPhone

1. Open Settings > Bluetooth.
2. Find each Phonak entry.
3. Tap the information icon beside the entry.
4. Select Forget This Device.
5. Repeat for the remaining Phonak entries.
6. Open myPhonak and forget the devices there if they are still stored.
7. Restart the CROS system to enable pairing mode.
8. Open myPhonak and select Pair hearing aids.
9. Accept each iPhone Bluetooth pairing request.
10. Follow any additional myPhonak instructions for phone calls and streaming.

If another iPhone, iPad, or computer is nearby and already paired with the hearing system, temporarily switch off Bluetooth on that device while completing the new pairing.

Pair Phonak CROS With myPhonak

The myPhonak app provides compatible Phonak users with controls such as program changes, volume adjustments, status information, Bluetooth setup, and CROS-specific controls on supported models.

Phonak also provides a CROS balance control on supported CROS EON, Infinio, Lumity, and Paradise systems, allowing the balance between the CROS side and hearing-aid side to be adjusted when that feature is available in the fitting.

myPhonak Pairing Steps

1. Charge the devices or install fresh batteries where applicable.
2. Turn Bluetooth on.
3. Update myPhonak to the latest available version.
4. Open myPhonak and choose Pair hearing aids.
5. Put the hearing system into pairing mode.
6. For rechargeable devices, restart them using the charger or device buttons according to the model instructions.
7. For devices using replaceable batteries, opening and closing the battery door normally restarts the device.
8. Continue in myPhonak while the devices are within their pairing window.
9. If two devices should be detected, wait until both appear before completing the process.
10. Accept the Bluetooth pairing requests.

Keep the phone and hearing devices close together during setup.

Check Bluetooth and App Settings

If pairing works but connection problems return, check:

• Bluetooth is still enabled.
• myPhonak has the permissions requested by the operating system.
• The phone is not in a power-saving mode that is aggressively stopping apps.
• No second phone is currently using the myPhonak connection.
• The Phonak devices are adequately charged.
• Streaming has not been disabled within myPhonak on a model that provides that setting.

For Infinio Ultra and newer hearing aids, Phonak provides a Streaming via Bluetooth control under the Devices area of myPhonak. If streaming has been switched off there, calls and media may not work even when other app functions remain available.

Reconnect After a Full Reset

If the normal re-pairing process fails, Phonak’s current troubleshooting guidance recommends removing the Bluetooth entries and app pairing completely. If the connection still cannot be rebuilt, uninstall and reinstall myPhonak, then run its pairing workflow again.

1. Remove all relevant Phonak entries from the phone’s Bluetooth settings.
2. Forget the hearing system from inside myPhonak.
3. Restart the phone.
4. Restart the hearing system.
5. Reopen myPhonak and attempt pairing.
6. If it still fails, uninstall myPhonak.
7. Reinstall it from the official app store.
8. Grant the required permissions and pair again.

A full app reset is more appropriate than repeatedly performing unrelated Android recovery-mode procedures.

Fix Bluetooth Streaming and Call Drops

When myPhonak connects but calls or media still fail, troubleshoot the streaming connection separately.

If the App Connects but Audio Does Not

Different Bluetooth connections can be involved in app control and audio streaming, especially on earlier Phonak generations. This means the app may appear healthy while the phone-call/audio connection is missing.

Try the following:

1. Open myPhonak and check whether it offers See instructions, Optional settings, or another streaming setup option.
2. Check the phone’s Bluetooth list for the Phonak streaming entry.
3. Restart the hearing system to put it back into pairing mode.
4. Complete the additional call/audio pairing if your generation requires it.
5. Play a short audio clip and confirm that the phone shows the Phonak system as the output device.
6. Make a test call.

Phonak notes that Infinio Ultra and newer models can enable streaming and phone calls as part of myPhonak pairing, while earlier generations may use an additional pairing step.

Prevent Other Devices From Taking the Connection

Current Phonak EON, Infinio, Lumity, and Paradise hearing aids can be paired with up to eight Bluetooth devices, with up to two connected at the same time. Marvel models have different limits.

However, a hearing aid cannot maintain active myPhonak app connections with two phones simultaneously. If you frequently move between phones, disconnect the app connection from one before trying to use myPhonak on the other.

If pairing a new phone fails, temporarily disable Bluetooth on previously paired nearby devices and try again.

If Only One Hearing Aid Appears

If a pair that should operate together cannot be detected as a pair, restart both devices and repeat the search. If the problem continues, the devices may need to be checked by your hearing-care professional.

Phonak notes that hearing aids intended to work as a pair must be correctly fitted together. A fitting or configuration problem cannot always be repaired from the phone.

Which Phones Work Best With Phonak CROS?

There is no single Samsung, Google Pixel, or iPhone model that can be declared universally “best” for every Phonak CROS user. Compatibility depends on the exact CROS generation, receiving hearing aid, operating-system version, Bluetooth implementation, myPhonak version, and phone settings.

A better buying checklist is:

• Confirm the phone meets the current myPhonak operating-system requirements.
• Confirm Bluetooth 4.2 or newer and Bluetooth Low Energy support.
• For Android, use a Google Mobile Services-certified device when required by the current myPhonak specification.
• Check the exact model through Phonak’s compatibility resources.
• Keep the phone updated, but be prepared to rebuild the Bluetooth pairing after a major OS update.
• If possible, test your CROS system with the phone before committing to a purchase.

Modern iPhones and modern Android phones can both work well with compatible Phonak systems. Blanket claims that Android is always more reliable than iPhone, or that a particular Galaxy or Pixel model is always superior, are not supported by Phonak’s general compatibility guidance.

When to Contact Your Hearing-Care Professional

Phone-side troubleshooting cannot fix every problem. Contact your hearing-care professional when:

• the CROS system itself does not appear to power on normally;
• only one device repeatedly appears when both should be fitted together;
• myPhonak reports a device/fitting problem;
• the system stopped working after a hearing-aid fitting or firmware change;
• Bluetooth troubleshooting succeeds but the hearing performance is still abnormal;
• you need the hearing devices re-fitted or checked with Phonak fitting software.

Frequently Asked Questions

Should Hearing Aid Compatibility Be on or off on iPhone?

Apple’s Hearing Aid Compatibility setting can reduce interference or improve acoustic compatibility with some hearing aids, particularly in telecoil-related use. It is separate from myPhonak Bluetooth pairing and does not itself enable Phonak streaming, firmware updates, or app control. You can leave it on if it improves your listening experience, but it is not a substitute for correctly pairing the Phonak CROS system.

What cell phones are compatible with Phonak hearing aids?

Compatibility depends on the hearing-aid model and current myPhonak requirements. Phonak’s current U.S. guidance lists iPhones running iOS 16 or newer and Google Mobile Services-certified Android phones running Android 10 or newer, with Bluetooth 4.2 and Bluetooth Low Energy capability. Always check the latest Phonak compatibility information for your exact model before buying a phone.

Which Phonak hearing aid is the best in 2026?

There is no single best Phonak model for every user. Phonak’s newer lineup includes Audéo EON Sphere, while CROS EON is designed for people who need a CROS solution for single-sided hearing loss. The right device depends on your hearing test, ear-specific hearing loss, speech-in-noise needs, physical fit, charging preference, and professional fitting requirements.

Which mobile phone is best for hearing-aid users?

Choose a phone that is officially compatible with your hearing system rather than relying on a brand ranking. Recent iPhones, Samsung Galaxy phones, Google Pixel phones, and other modern Android devices can all work well when they meet Phonak’s requirements. Verify the exact phone and OS version and, if possible, test the phone with your hearing system before purchase.

Why does myPhonak connect but phone calls or music do not stream?

The app-control connection and audio-streaming connection can be different, particularly on older Phonak generations. Open myPhonak and complete any “See instructions” or optional streaming setup it provides. For Infinio Ultra and newer models, also check that Streaming via Bluetooth has not been disabled in the app.

How long is a Phonak hearing aid in Bluetooth pairing mode?

Phonak generally provides a three-minute pairing window after the hearing aid is restarted and placed into pairing mode. If the phone does not find the system in time, restart the hearing devices again and repeat the search.

Can Phonak CROS connect to two phones?

Current EON, Infinio, Lumity, and Paradise hearing aids can be paired with several Bluetooth devices and can have up to two Bluetooth devices connected at once. However, the hearing aids can maintain only one active myPhonak app connection at a time, so switching the app between phones may require disconnecting it from the first device.

Conclusion

Phonak CROS phone problems after an Android or iPhone update are often resolved without changing phones or replacing the hearing system. Start by restarting myPhonak, Bluetooth, the phone, and the hearing devices. If that fails, remove the old Phonak Bluetooth entries, forget the devices inside myPhonak, and pair them again within the device’s pairing window.

Also account for the CROS generation. Newer Phonak products handle app, call, and streaming setup differently from some older models. Instead of assuming that Samsung, Pixel, or iPhone is inherently more reliable, verify the exact phone and operating-system combination against current Phonak requirements. If the devices themselves do not function normally or cannot be fitted together correctly, involve your hearing-care professional.
