Audeara BT-03 Audio Broadcaster | Auracast Bluetooth Transmitter for Shared Spaces

Broadcast high-quality audio to an unlimited number of listeners at the same time. The Audeara BT-03 uses Auracast™ technology to transmit sound directly to compatible headphones, earbuds, or receivers — without pairing, without disruption, and without limits on who can listen. 

Designed for shared spaces where everyone deserves to hear clearly.

Best for

• Hospitality venues — pubs, sports bars, hotels, and restaurants
• Places of worship, classrooms, and conference centres
• Aged care facilities and accessibility-focused environments
• Anywhere multiple people need to listen to the same audio source simultaneously
• Venues running multiple screens with different audio feeds

How it works

Connect the BT-03 to your TV, computer, or venue sound system via optical, AUX, or HDMI ARC. It broadcasts audio via Auracast™ to any compatible device within range — up to 50 metres. Built-in bypass outputs mean your existing speakers keep playing while the broadcast runs simultaneously. No pairing required. Listeners simply select the Auracast™ broadcast on their compatible device and tune in.

In larger venues, multiple BT-03 units can operate in the same space at once, each creating its own independent broadcast. In a sports bar, that means one screen broadcasting the football, another the tennis — listeners choose what they hear.
