Made for iPhone (MFi) on iPhone
Quick answer
Supported. Supported natively. Compatible hearing aids pair through the iOS accessibility settings rather than through the ordinary Bluetooth menu, which is the step that confuses people most often.
What is Made for iPhone (MFi)?
A hearing aid specific streaming protocol Apple introduced long before any cross-platform standard existed. It carries audio directly from an iPhone into compatible hearing aids and exposes controls in the iOS accessibility settings.

On iPhone: Supported.
| Platform | Support | Detail |
|---|---|---|
| iPhone | Supported | Supported natively. Compatible hearing aids pair through the iOS accessibility settings rather than through the ordinary Bluetooth menu, which is the step that confuses people most often. |
| Android | Not supported | Not supported. MFi is an Apple protocol and an Android phone cannot use it, whatever the hearing aid is capable of. The Android equivalent is ASHA or, on newer hardware, Bluetooth LE Audio. |
How Made for iPhone (MFi) compares with the other routes on iPhone
Published figure From a named standards body, regulator or professional classification. Reproduced here, not derived by us.
Made for iPhone (MFi) is one of six routes, of which 2 are fully supported on iPhone.
| Route | On iPhone | What it needs |
|---|---|---|
| Made for iPhone (MFi) | Supported | Supported natively. Compatible hearing aids pair through the iOS accessibility settings rather than through the ordinary Bluetooth menu, which is the step that confuses people most often. |
| ASHA, Audio Streaming for Hearing Aids | Not supported | Not supported. ASHA is an Android protocol; on an iPhone the equivalent is MFi. |
| Bluetooth LE Audio | Depends on the device generation | Increasingly supported on recent hardware, and the direction Apple is moving, but it depends on the device generation rather than on the operating system alone. |
| Auracast broadcast audio | Depends on the device generation | Depends on device generation rather than on the operating system. Check the specific hardware. |
| Telecoil, the T setting | Not applicable, it works without a phone | Not applicable, and that is the point. A telecoil works with an induction loop or a neckloop regardless of what phone you own or whether you own one at all. |
| Classic Bluetooth with an intermediate streamer | Supported | Works, because the phone is only talking to an ordinary Bluetooth accessory rather than to the hearing aids. |
Common questions
- Does Made for iPhone (MFi) work with iPhone?
- Supported. Supported natively. Compatible hearing aids pair through the iOS accessibility settings rather than through the ordinary Bluetooth menu, which is the step that confuses people most often. Note that this describes the platform side only: the hearing aid has to support the protocol as well, and whether yours does is a specification published by its manufacturer for that model rather than something that can be inferred from the brand.
- How do I find out whether my hearing aids support this?
- Check the specification sheet for your specific model on the manufacturer site, or the documentation supplied with the devices. Streaming support changed substantially between device generations, so the brand name alone tells you very little and a model from two years ago may differ from the current one carrying a similar name.
- What if my hearing aids do not support any direct protocol?
- An intermediate streamer is the answer. It is a separate device worn around the neck or clipped on that receives ordinary Bluetooth from the phone and relays it to the hearing aids on a short range link of the manufacturer own design. It works with practically any phone, at the cost of an extra device to carry and charge.
- Does streaming affect battery life?
- Yes, substantially. Regular streaming roughly doubles the current a hearing aid draws compared with amplification alone, because the device is running a radio as well as an amplifier. On a battery device this can more than halve the days between changes, and on a rechargeable one it shortens the time between charges noticeably.
- Is there an option that does not depend on my phone at all?
- A telecoil. It is a small copper coil built into many hearing aids that picks up a magnetic signal rather than a radio one, works with any induction loop or neckloop, and is entirely independent of your phone and its operating system. Not every device has one, and on many that do it has to be enabled by whoever programmed the aid.
