Auracast™ Transmitters & Receivers

A: Auracast is the latest Bluetooth technology that lets one device broadcast audio to many listeners at the same time.

Unlike classic Bluetooth (typically one-to-one), Auracast enables shared listening, public broadcasts, and assistive listening—with great quality and low delay.

A:

• Auracast Transmitters (Send Audio): Audikast 4 / 4HA, C82 Aura, Oasis Aura, and other Auracast-enabled transmitters.
• Auracast Receivers (Hear Audio): Auracast headphones, earbuds, receivers, and compatible hearing aids.

Together, they form a complete Auracast ecosystem—from source to listener.

A: Yes, depending on what you have:

• If your headphones or hearing aids support Auracast / LE Audio, they can join an Auracast broadcast directly.
• If they are classic Bluetooth only, many Avantree transmitters also support traditional Bluetooth connections—so you can use them today and still be ready for Auracast later.

A: Not at all. Most setups are simple:

• Connect the Auracast transmitter to your TV, phone, or audio source
• Put your Auracast receiver (headphones/earbuds/receiver) into Auracast mode
• Select the broadcast and start listening

Many Avantree receivers also support auto-reconnect, so daily use is effortless.

A: Auracast is built for both everyday and public listening:

• Shared TV listening at home (no volume conflicts)
• Assistive listening for hearing aid users
• Churches, events, gyms, and venues
• Travel & public spaces with broadcast audio
• Future public Auracast broadcasts as adoption grows

A: While Avantree transmitters and receivers are universally compatible, using both sides from Avantree can still be beneficial.

They’re optimized to work together for seamless auto-reconnect every time you power on—so there’s less fiddling with apps, menus, or repeated setup.

The result is a simpler, more reliable listening experience, especially for daily TV listening, shared audio, and assistive listening.
