Auracast is Here: Unlock a New Era of Shared Audio with EarFun
Get ready to share your soundtrack with the world—or just your friends—like never before. Auracast™ is the revolutionary audio broadcasting technology powered by Bluetooth LE Audio, and it's set to transform how you use your EarFun headphones and speakers.
Imagine syncing your new EarFun earbuds with your friends' headphones to watch a movie on a tablet, or effortlessly linking three EarFun speakers around the pool for synchronized, room-filling sound. Auracast makes it all possible.
Here is your guide to the future of wireless listening.
What is Auracast™ and Why It's a Game-Changer
Auracast is a groundbreaking new capability of Bluetooth® LE Audio that allows one audio source to broadcast sound to an unlimited number of nearby receiving devices.
Unlike traditional Bluetooth, which is a private, one-to-one connection, Auracast creates a public or private "radio station" for audio. Anyone with an Auracast-enabled device can tune in.
| Traditional Bluetooth (Classic) | Auracast™ (LE Audio) |
| Connection: One-to-One (or limited One-to-Two) | Connection: One-to-Unlimited |
| Primary Use: Private listening, single speaker connection. | Primary Use: Social sharing, public broadcasting, accessibility. |
| Efficiency: Higher power consumption. | Efficiency: Ultra-low energy (Bluetooth LE Audio). |
The Core Benefits for EarFun Users:
-
Unlimited Social Sharing: Share your music, podcast, or movie with any number of friends nearby, instantly. No more handing over an earbud—everyone tunes in with their own EarFun Air or EarFun Free earbuds.
-
Perfect Speaker Sync: Connect multiple EarFun portable speakers throughout your home or backyard for a perfectly synchronized audio experience. The low-latency LC3 codec ensures zero delay across all devices, making multi-speaker setups effortless and flawless.
-
Enhanced Accessibility (Silent Disco & Public Audio): Auracast allows you to tune into public broadcasts.
- Airports/Gyms: Connect your EarFun earbuds directly to a TV screen at the gym or to an important gate announcement at the airport, filtering out the background noise.
- Theaters/Lecture Halls: Auracast can deliver assistive listening streams directly to your EarFun devices or hearing aids, offering crystal-clear, personalized audio.
How Does Auracast Work with Your EarFun Gear?
Auracast operates using three simple roles:
-
The Transmitter (The Source): This is the device sending the audio broadcast. It could be your smartphone, laptop, smart TV, or an Auracast-enabled speaker like the future EarFun UBOOM X.
-
The Receiver (The Listener): This is your personal EarFun device—your earbuds, headphones, or a secondary speaker—which receives the audio stream.
-
The Assistant (The Tuner): Usually your smartphone (via a dedicated EarFun app or Bluetooth settings), the Assistant scans the environment, detects available Auracast broadcasts (like a Wi-Fi network), and lets you choose which stream to join.
Joining a Stream is as Easy as Connecting to Wi-Fi:
To join an Auracast broadcast, you simply open your device's settings (or the EarFun app) to see a list of available Auracast streams. You can select the one you want, and your EarFun earbuds or speaker will instantly connect and synchronize. For private streams, a password or QR code may be required—just like a private Wi-Fi network.
EarFun + Auracast: The Future of Shared Listening
Auracast is a cross-brand technology built into the latest Bluetooth standard. This means your Auracast-enabled EarFun devices will connect seamlessly with compatible devices from any other brand.
The combination of EarFun's commitment to delivering premium, high-quality audio and the unparalleled flexibility of Auracast means a better listening experience for you, your friends, and the world around you.
