Sharing audio from a single device to multiple Bluetooth headphones or earbuds — like AirPods, Sony WH-1000XM3, or other wireless models — is a common desire, whether you’re traveling, watching movies with friends, or enjoying music together. While most smartphones are designed to connect to only one Bluetooth audio device at a time, there are several effective methods to achieve multi-listener audio experiences.

🔹 Method 1: Utilize Built-In Dual Audio or Audio Sharing Features

Android Devices (Samsung Galaxy Series):

Samsung’s Dual Audio feature allows certain Galaxy phones to connect to two Bluetooth audio devices simultaneously. Here’s how to set it up:

1. Pair the First Device:

• Navigate to Settings > Connections > Bluetooth.
• Pair and connect the first Bluetooth audio device.

2. Enable Dual Audio:

• Tap on the three-dot menu (More options) in the Bluetooth settings.
• Select Advanced and toggle on Dual Audio.

3. Pair the Second Device:

• Pair and connect the second Bluetooth audio device.
• Both devices should now play audio simultaneously.

Apple Devices (iPhone and iPad):

Apple’s Audio Sharing feature, introduced in iOS 13.1, allows users to share audio with two pairs of compatible headphones. This feature works with:

• AirPods (1st generation or later)
• Powerbeats Pro
• Beats Solo Pro
• Other Beats headphones with the H1 or W1 chip

To use Audio Sharing:

1. Connect the First Pair:

• Connect your AirPods or compatible Beats headphones to your iPhone or iPad.

2. Initiate Audio Sharing:

• Open the Control Center.
• Tap on the AirPlay icon.
• Select Share Audio.

3. Connect the Second Pair:

• Bring the second pair of headphones close to your device.
• Follow the on-screen instructions to connect.

Limitations:

• These features typically support only two devices simultaneously.
• Compatibility depends on the device model and software version.

🔹 Method 2: Use a Bluetooth Transmitter

For scenarios where built-in features are insufficient, a Bluetooth transmitter like THE BRIDGE from EasyBridge offers a versatile solution. This device allows multiple Bluetooth headphones to connect to a single audio source, such as a smartphone, tablet, or in-flight entertainment system.

Key Features of THE BRIDGE:

• Multi-Device Connectivity:
  Connects up to two Bluetooth audio devices simultaneously.
• Versatile Input Options:
  Compatible with 3.5mm audio jacks, making it suitable for various devices, including airplane entertainment systems.
• Portability:
  Compact design for easy transport during travel.

Setup Instructions:

1. Connect THE BRIDGE to the Audio Source:

• Plug THE BRIDGE into the 3.5mm headphone jack of your device.

2. Power On THE BRIDGE:

• Turn on the transmitter to initiate pairing mode.

3. Pair Bluetooth Headphones:

• Put your Bluetooth headphones into pairing mode.
• THE BRIDGE will automatically connect to the headphones.
• It will automatically start searching for the second pair of headphones.

Use Cases:

• Air Travel:
  Share in-flight entertainment audio with a travel companion using your own Bluetooth headphones.
• Home Entertainment:
  Watch movies or listen to music with a partner without disturbing others.
• Fitness Activities:
  Share workout playlists during joint exercise sessions.

Considerations:

• Audio Latency:
  Ensure that THE BRIDGE and your headphones support low-latency codecs (e.g., aptX Low Latency) to minimize audio delay.
• Battery Life:
  Check the battery life of THE BRIDGE to ensure it meets your usage needs during travel or extended listening sessions.

🔹 Method 3: Leverage Emerging Technologies like Auracast

Bluetooth LE Audio introduces Auracast, a feature that allows one device to broadcast audio to multiple receivers. This technology enables public audio sharing in venues like gyms, airports, and theaters.

Advantages of Auracast:

• Multi-Device Broadcasting:
  Stream audio to an unlimited number of compatible Bluetooth devices.
• Public Accessibility:
  Facilitates audio sharing in public spaces without the need for individual connections.

Current Limitations:

• Device Compatibility:
  Requires both the broadcasting device and receiving headphones to support Bluetooth LE Audio and Auracast.
• Availability:
  As of now, Auracast is being integrated into select devices, and widespread adoption is forthcoming.

🔹 Conclusion

While traditional Bluetooth connections limit audio sharing to a single device, advancements in technology provide multiple avenues to share audio with multiple listeners:

• Built-In Features:
  Utilize Dual Audio or Audio Sharing on compatible devices for two-listener setups.
• Bluetooth Transmitters:
  Devices like THE BRIDGE offer flexible solutions for connecting multiple headphones to a single source.
• Emerging Technologies:
  Stay informed about developments like Auracast for future multi-device audio broadcasting capabilities.

By selecting the method that aligns with your devices and needs, you can enjoy shared audio experiences seamlessly.
