Auracast broadcast audio
Quick answer
A broadcast layer built on Bluetooth LE Audio. A transmitter broadcasts and any number of receivers in range can tune in, which is why it is being deployed in airports, cinemas and places of worship as a replacement for the older induction loop. On iPhone: depends on the device generation. On Android: depends on the device generation.
What Auracast broadcast audio is
A broadcast layer built on Bluetooth LE Audio. A transmitter broadcasts and any number of receivers in range can tune in, which is why it is being deployed in airports, cinemas and places of worship as a replacement for the older induction loop.
The important property for a reader is that Auracast is NOT tied to one hearing aid manufacturer. A transmitter that speaks it works with any Auracast capable receiver, which is why an Auracast television transmitter costs roughly a third of a brand specific streamer. The catch is that the hearing aid has to support it, and most devices sold before the standard existed do not.
iPhone: Depends on the device generation. Android: Depends on the device generation.

Common questions
- What is Auracast broadcast audio?
- A broadcast layer built on Bluetooth LE Audio. A transmitter broadcasts and any number of receivers in range can tune in, which is why it is being deployed in airports, cinemas and places of worship as a replacement for the older induction loop. Whether any particular hearing aid supports it is a manufacturer specification for that model rather than something that follows from the brand, since support changed substantially between device generations.
- Which phones support Auracast broadcast audio?
- On iPhone: depends on the device generation. On Android: depends on the device generation. Where support is described as depending on the device generation, that is because the capability is hardware rather than software, so an older handset running a current operating system version may still lack it.
- Do I need this specifically?
- Only if you want audio from a phone delivered directly into your hearing aids. Plenty of people never stream at all and use their aids purely for amplification. If you do want it, the route available to you is decided by your hearing aids first and your phone second, in that order.
- What is the fallback if this is unavailable?
- An intermediate streamer, which receives ordinary Bluetooth from the phone and relays it to the hearing aids on a manufacturer specific short range link. It works with practically any phone and any reasonably recent hearing aid, at the cost of an extra device to carry and charge. It is the reliable answer for older devices.
- Will this still work in five years?
- The platform specific protocols are expected to converge on Bluetooth LE Audio over time, so anything tied to one platform is the more likely to be superseded. A telecoil is the outlier: it has worked for decades, is independent of any phone ecosystem, and will keep working with induction loops regardless of what happens to Bluetooth.
