Auracast is a Bluetooth technology that allows a single audio source, like a television or microphone, to broadcast high-quality sound to an unlimited number of nearby earbuds or hearing aids simultaneously. Instead of pairing your device directly to a screen, you simply scan for an available audio channel and tune in, much like selecting a local Wi-Fi network.
If you are at a location that supports Auracast, you can tune your compatible hearing aids or earbuds directly to the public microphone’s Auracast broadcast, allowing you to hear the announcements or speaker with perfect clarity while completely cutting out distracting background crowd noise.
