Microsoft Tests Shared Audio in Windows 11 — Stream Sound to Two Devices at Once
Microsoft is testing a new feature in Windows 11 that allows users to stream audio to two Bluetooth devices at the same time. The “Shared Audio” feature, now available for Windows Insiders, aims to make it easier for people to enjoy the same music, movie, or call together without needing special hardware.
Background / Context
Audio sharing is not a new concept—Apple introduced a similar feature with its AirPods back in 2019. But until now, Windows users had to rely on third-party software or Bluetooth splitters to achieve the same effect. With this test, Microsoft appears to be catching up and expanding flexibility across a wider range of Bluetooth headsets.
Key Developments / Details
The Shared Audio feature is being tested in recent Windows Insider Preview builds. It’s built on Bluetooth LE (Low Energy) Audio, which offers better sound quality and lower latency while conserving power. The update allows users to connect two compatible Bluetooth audio devices simultaneously and stream the same sound to both—ideal for watching a video or listening to music with someone nearby.
According to Microsoft’s Windows Insider team, the rollout is part of broader improvements to Bluetooth LE Audio support in Windows 11. The company is testing stability and compatibility before considering a wider release in future updates.
Technical Explanation
Bluetooth LE Audio is a next-generation standard that uses the LC3 codec for higher-quality sound at lower bitrates. This allows devices to transmit audio efficiently without draining battery life. The Shared Audio feature uses this technology to synchronize audio output across two devices without noticeable lag or desynchronization—something traditional Bluetooth struggled with.
Implications
If released publicly, this feature could change how users experience entertainment and collaboration on Windows devices. Whether it’s two people watching a movie together, a couple sharing a playlist, or professionals reviewing audio edits, Shared Audio adds convenience without extra accessories. It could also enhance accessibility for users with hearing aids or specialized Bluetooth devices.
Challenges / Limitations
For now, the feature remains experimental and may only work with select Bluetooth LE Audio-supported headphones. Users with older devices or traditional Bluetooth headsets may not experience full compatibility. Microsoft hasn’t provided a timeline for a general release, signaling that the company is still fine-tuning the experience.
Future Outlook
As Bluetooth LE Audio becomes more common across devices, Microsoft’s Shared Audio could become a standard Windows feature. The company’s ongoing testing suggests it wants to build a more connected, social, and accessible computing experience. Future updates could also expand this feature to PCs, tablets, and other Windows devices.
Conclusion / Summary
Microsoft’s Shared Audio test marks another step in making Windows 11 more user-friendly and inclusive. By enabling seamless audio sharing between two Bluetooth devices, it brings convenience that users have long requested—and positions Windows as a more social, media-friendly operating system.
