Wireless audio technology is rapidly transforming how people with hearing loss experience sound. One of the most important innovations is Auracast, a new Bluetooth capability designed to broadcast audio to multiple devices at the same time. In this guide, we explain what Auracast is, how it works with hearing aids, and which hearing aids have Auracast compatibility.
Auracast in hearing aids refers to the ability of hearing devices to receive broadcast audio streams using Bluetooth LE Audio. This allows you to enable Auracast broadcast audio. In practice, this means that hearing aids with Auracast can connect directly to public audio broadcasts without needing additional accessories.
For example, users could:
The goal of Auracast technology is to improve accessibility and make shared listening easier for people with hearing loss.
Auracast works through three main components:
An Auracast transmitter sends an audio broadcast signal to nearby compatible devices.
These transmitters may be installed in:
Once activated, the transmitter creates a broadcast stream that compatible devices can join.
Auracast is a relatively new technology, so only the newest hearing aid models support it or will support it through future updates.
Manufacturers are gradually introducing Auracast Bluetooth hearing aid compatibility in their latest devices as Bluetooth LE Audio becomes more widely adopted.
Generally, premium or next-generation hearing aids with advanced connectivity features are the most likely to support Auracast technology.
As the technology expands, more models are expected to become Auracast compatible hearing aids over the coming years.

Auracast can make public spaces more accessible by broadcasting audio directly to hearing devices.
Direct audio streaming reduces background noise and improves speech clarity.
Multiple users can join the same broadcast simultaneously, which is useful for events, lectures, or entertainment venues.
Auracast integrates with modern Bluetooth ecosystems, making it easier to connect hearing aids with other compatible devices.

In addition to hearing devices, Auracast technology is also being implemented in Auracast Bluetooth speakers and public audio infrastructure.
For example, a venue might install an Auracast transmitter that broadcasts sound from a microphone or media system. Visitors with compatible devices — including hearing aids — can tune into the stream. A local example of this is the Sydney Opera House, who installed Auracast technology in 2025.
This approach has the potential to replace traditional assistive listening systems used in places like:
Because Auracast works with standard Bluetooth technology, it can make assistive listening more accessible and easier to deploy.
Auracast is expected to become an important feature in the next generation of hearing technology.
As adoption grows, we are likely to see:
For people with hearing loss, this technology could significantly improve how they access sound in everyday environments.
