HearAura is the iPhone remote for Auracast™, the Bluetooth broadcast that sends a place's sound straight into your hearing aids or earbuds: the TV at the gym, the gate announcement, the sermon, the show. No neck loop, no borrowed headset, no room noise.
Free. No account, no ads, no tracking. iPhone and Apple Watch.
Listen
Scan the QR code on the venue's sign, or search the airwaves nearby. HearAura tells your hearing aids which broadcast to join, then gives you broadcast volume and mute on your iPhone and Apple Watch. The sound itself goes straight from the transmitter to your ears, never through the phone.
Hearing aids
Made for iPhone hearing aids pair in Settings, and HearAura finds them by itself. LE Audio hearing aids and earbuds that aren't Made for iPhone show up under Find hearing aids nearby: both ears together, one tap to add, and iPhone asks you to pair. Not sure which kind you have? The app explains the three kinds in plain words.
Captions
Turn the room's speech into large, readable text. When a venue publishes captions for its broadcast, HearAura shows those; otherwise it captions the room through your iPhone's microphone, and says so. Either way the transcription happens entirely on your iPhone. Meeting Mode keeps a transcript you can save, and captions in another language can be translated on the device.
Channels
Host a Channel and friends join with a code or QR. Everyone hears the speaker through their own hearing aids or earbuds, and every speaker's words appear as captions on every phone. It runs over the local network, so no internet is needed and nothing passes through a server. With Take turns, one person speaks at a time.
Home
Save the broadcasts you join often, like the TV or the kitchen speaker, as presets, and see your hearing devices at a glance. No hardware yet? Listen has a built-in demo that walks through a join, clearly labelled as a simulation.
iPhone keeps them connected. Pair them in Settings → Accessibility → Hearing Devices. Many newer ones (ReSound, Jabra, Oticon, Starkey and others) also have LE Audio and can join broadcasts.
The kind of Bluetooth Auracast uses. Add them in HearAura with Find hearing aids nearby; iPhone asks you to pair. Auracast-capable LE Audio earbuds work the same way.
Like ordinary headphones, including AirPods today. Music and calls work, but they can't hear Auracast, and no app can change that. HearAura's captions and Channels still work with them, and so does an Auracast receiver you wear.
Look for "Auracast" or "LE Audio" on the box, or ask your audiologist. Inside the app, Settings → Device check tells you what your hearing aids can do, with no broadcast needed. Watch: Which hearing aids work?
Every video is silent, with every word on screen, and each one has a written transcript. The same videos are in the app under Settings → Help videos.
How broadcasts reach your hearing aids, and what HearAura does.
What is Auracast? A Bluetooth broadcast anyone nearby can tune into.
Sound goes straight to your hearing aids. Theaters, TVs and lecture halls can broadcast their sound. Your hearing aids pick it up directly. It doesn't go through your phone.
HearAura is the remote. iPhone has no built-in Auracast control. HearAura tells your hearing aids which broadcast to join.
Three ways to join. Scan the QR code on the venue's sign. Search for broadcasts nearby. Or open a link someone shared with you.
The three kinds of Bluetooth hearing devices, and how to tell which you have.
Which hearing aids work? Hearing aids use Bluetooth in three ways. Only some can hear broadcasts.
1. Made for iPhone. iPhone keeps them connected. Pair in Settings, Accessibility, Hearing Devices. Many newer ones also use LE Audio and can join broadcasts.
2. LE Audio, not Made for iPhone. The kind Auracast uses. Add them in HearAura with Find them nearby. iPhone asks you to pair.
3. Classic Bluetooth only. Like headphones. Music and calls work, but not Auracast. No app can change that.
How to tell which you have. 1. Look for Auracast or LE Audio on the box. 2. Paired in Hearing Devices? They are Made for iPhone. 3. Only LE Audio devices appear in Find them nearby. Having the maker's app doesn't tell you which kind.
Pair them in Settings. HearAura finds them by itself.
Pair Made for iPhone hearing aids. Open Settings. Tap Accessibility, then Hearing Devices.
Turn your hearing aids off, then on. Battery doors: open, then close. Charger: in, then out. You then have about three minutes to pair.
Pair each ear. 1. Tap their name when it appears. 2. Tap Pair for each ear. 3. Wait for the beeps and a checkmark. On iOS 27, tap Pair MFi Hearing Device first.
Come back to HearAura. HearAura finds them by itself. It says Connected when they are ready.
For hearing aids and earbuds that are not Made for iPhone.
Not Made for iPhone? On Listen, tap Not Made for iPhone? Find them nearby. It's for LE Audio hearing aids and earbuds.
Make them easy to find. Turn your hearing aids off, then on. Earbuds: put them in pairing mode.
Tap Add. Both ears show up together. Only LE Audio devices are listed.
Tap Pair when iPhone asks. iPhone asks once for each ear. Then you can join broadcasts.
Next time. HearAura reconnects to them by itself. Remove from HearAura, on the same page, stops that. Classic Bluetooth devices never appear, because they can't hear broadcasts.
Scan a QR code or search nearby, then set the broadcast volume.
Join a broadcast. Scan the QR code on the venue's sign. Or tap Scan for broadcasts to search nearby.
No broadcast in the list? Not every transmitter shows up in a search. Look for the venue's QR code sign, or ask staff for it.
Your aids tune in. HearAura sends the join. The sound goes straight to your hearing aids.
Now Playing. Change the broadcast volume, or mute it. Tap Leave to stop listening.
Captions, Channels, and Auracast receivers still help.
When your aids can't hear broadcasts. Some hearing aids and earbuds can't receive Auracast. HearAura still helps in three ways.
1. Captions. Turns speech into text on your screen. It uses the venue's caption feed if there is one, or the room through your phone's mic.
2. Channels. People nearby talk through their phones, with live captions. No internet needed.
3. An Auracast receiver. A receiver you wear or plug in picks up the broadcast and passes the sound on.
The longer version, for audiologists, hearing aid makers and transmitter makers: what the hearing aid needs, and a two-minute check.
Auracast on iPhone with non-MFi hearing aids. For listeners, hearing aid makers and transmitter makers.
The phone is the remote, not the speaker. iPhone has no built-in Auracast assistant. Hearing aids can hear a broadcast, but something has to tell them which one. HearAura is that remote control: a Broadcast Assistant. Audio goes from the transmitter straight to the aids. The phone only sends the join.
Made for iPhone (MFi) aids. Works today. iOS keeps MFi hearing aids connected. HearAura uses that link to send the join, through the standard Bluetooth Broadcast Audio Scan Service.
Non-MFi aids. The gap. They pair as regular Bluetooth devices, or through the maker's app. iOS does not hand HearAura a link to them. So before version 1.2, HearAura could not see them.
The fix: Find hearing aids nearby. New in HearAura 1.2. HearAura connects to the aids itself, over Bluetooth LE. iOS shows its normal pairing prompt. Tap Pair. Then join broadcasts and set broadcast volume, just like MFi aids.
What it looks like. HearAura lists the hearing aids it finds nearby, both ears together. Tap Add, then Pair when iOS asks.
What the hearing aid needs. Receives Auracast (it is an LE Audio broadcast sink). Offers the Broadcast Audio Scan Service (0x184F) to a phone over Bluetooth LE. Accepts an LE connection from a second app, alongside the maker's app. Aids that only stream over classic Bluetooth cannot hear Auracast at all. No app can change that. For them: an Auracast receiver neckloop or dongle.
A two-minute check for manufacturers. Install nRF Connect on an iPhone. Scan, and connect to the hearing aid. Look for service 0x184F, Broadcast Audio Scan. Present: HearAura can drive it. Missing: the firmware needs to expose it. It is the standard Bluetooth SIG service that Android and Samsung's built-in assistants already use.
Tell us which models. Send us the hearing aid model names your users have, and we'll check what they support. support@hearaura.app, hearaura.app.
Auracast™ is broadcast audio built into Bluetooth. A venue transmits; anyone nearby with compatible hearing aids, earbuds, or headphones tunes in, like Wi-Fi for sound. It's an open standard from the Bluetooth SIG, so it works across brands. iPhone has no built-in way to pick a broadcast; HearAura is that missing remote.
Email support@hearaura.app. A person reads every message, usually replies within two business days, and accessibility problems go first. Tell us your iPhone model and your hearing aid or earbud brand and model; it saves a round trip.
