Microsoft Introduces Dual Bluetooth Audio Streaming in Windows 11 with LE Audio Support
Microsoft Adds Dual Bluetooth Audio Streaming to Windows 11
Microsoft has introduced a new shared audio feature in Windows 11 that lets users stream audio to two Bluetooth devices simultaneously. The feature is now rolling out to Windows Insiders in the Dev and Beta channels, marking a major upgrade for Bluetooth audio users.
🎧 What the New Shared Audio Feature Does
With this update, Windows 11 users can connect two sets of wireless headphones, speakers, earbuds, or hearing aids to one PC at the same time. Both connected devices can play the same sound, letting two people enjoy audio together — for example, watching a movie on a laptop while each person listens through their own Bluetooth headphones.
This shared audio capability is powered by Bluetooth LE Audio, a newer, more efficient standard designed to improve sound quality, latency, and power consumption across devices. LE Audio uses the Low Complexity Communication Codec (LC3), which delivers higher-quality sound at lower bitrates compared to traditional SBC codecs used in classic Bluetooth audio.
To enable it:
- Connect two Bluetooth LE Audio devices to your Windows 11 PC.
- Open the Quick Settings menu from the taskbar.
- Select “Shared audio (preview)”.
Once activated, both devices will play audio in perfect sync.
🔊 Why Bluetooth LE Audio Matters
The Bluetooth LE Audio platform represents one of the biggest leaps forward in wireless audio technology in years. It improves audio experiences in several ways:
- Lower power consumption, ideal for laptops and portable devices.
- Better audio quality, especially at lower bitrates.
- Multi-Stream Audio, which allows transmitting multiple synchronized audio streams from one source.
- Support for Auracast, a broadcasting technology that enables one device to transmit audio to many nearby receivers — think of a single laptop or TV streaming sound to multiple headsets in a room.
This Windows 11 update focuses on Multi-Stream Audio, enabling dual-device streaming for now, but it lays the foundation for broader Auracast functionality later.
💻 Supported Devices and System Requirements
Currently, the shared audio feature works only on select Copilot Plus PCs, which include the Surface Laptop 7 and Surface Pro 11 models equipped with Qualcomm Snapdragon X Series processors.
Microsoft has confirmed that support will expand to other devices soon, including:
- Galaxy Book5 360
- Galaxy Book5 Pro
- Future Copilot Plus PCs from other manufacturers
You’ll also need compatible Bluetooth LE Audio accessories, such as:
- Samsung Galaxy Buds 2 Pro
- Galaxy Buds 3 and Buds 3 Pro
- Sony WH-1000XM6 headphones
- Other upcoming LE Audio-capable earbuds and hearing aids
🧩 Comparison with Other Platforms
Microsoft’s adoption of Bluetooth LE Audio and shared audio puts Windows 11 in line with other major platforms already offering similar experiences.
- Google Pixel 8 series phones support LE Audio and allow streaming to two sets of headphones simultaneously.
- Samsung Galaxy S24 series introduced Auracast, enabling group audio sharing in public spaces, such as gyms or airports.
- Apple’s iOS 17 and macOS Sonoma support audio sharing on AirPods, although they rely on Apple’s proprietary W1/H1 chips rather than the open LE Audio standard.
Microsoft’s implementation differs by integrating this capability directly into the Windows 11 Bluetooth stack, making it available system-wide — not just for specific apps or devices.
🧠 Technical Background
The Bluetooth LE Audio framework first appeared in Windows 11’s August 2024 update, which added support for LC3 codec playback. This laid the groundwork for improved audio quality in games, video calls, and media playback.
The new dual audio streaming expands upon that base, combining Multi-Stream Audio (MSA) with system-level synchronization across two connected devices.
Each audio stream is transmitted separately, maintaining independent latency control for both receivers, ensuring a lag-free and synchronized experience — especially important when watching movies or playing games together.
Additionally, this new system supports hearing aid devices certified under the LE Audio standard, significantly improving accessibility for users who depend on assistive hearing technology.
🧪 How to Test It
If you’re a Windows Insider, here’s how to try out this feature:
- Update your PC to the latest Dev or Beta build (Build 26100 or newer).
- Pair two Bluetooth LE Audio-compatible devices through Settings → Bluetooth & devices → Add device.
- Open the Quick Settings panel (Win + A).
- Click the Audio Output menu → choose Shared audio (preview).
- Play music, video, or a game — both devices should play the same audio simultaneously.
You can also control volume for each device independently, though currently, both devices will share the same audio stream (no separate output management yet).
🔮 What’s Next
Microsoft plans to gradually expand shared audio support to more PCs as OEMs update Bluetooth drivers and firmware to fully implement LE Audio profiles.
Future updates may include:
- Full Auracast broadcasting, letting one PC stream audio to multiple public devices.
- Granular device mixing, allowing one person to listen to game audio while another hears music.
- Improved latency tuning for video synchronization.
This feature signals Microsoft’s broader investment in next-generation wireless audio, aligning with its push for Copilot Plus PCs that combine AI acceleration with smarter multimedia features.
