Microsoft has finally delivered one of the most requested audio features to Windows 11: the ability to share audio from a single PC to two sets of Bluetooth headphones or earbuds simultaneously. Dubbed Shared Audio, the feature arrives as part of the May 26, 2026 preview update KB5089573 (OS Build 22631.5116) and requires compatible Bluetooth LE Audio hardware. Once enabled, you and a friend can watch a movie, listen to music, or play a game together—each with your own private, wireless listening experience—without a cumbersome splitter or external transmitter.

What Is Shared Audio and How Does It Work?

Shared Audio leverages the Multi-Stream Audio capability built into Bluetooth LE Audio. Unlike Classic Bluetooth, which typically streams to only one device at a time, LE Audio can send synchronized, independent audio streams to multiple sinks. Windows 11 now exposes this capability through a simple toggle in Quick Settings.

When you activate Shared Audio, the PC simultaneously transmits two separate audio streams—left and right stereo channels—to each connected LE Audio device. Because both streams originate from the same source and are tightly synchronized, there is no perceptible delay between the two listeners. This makes it ideal for shared viewing or gaming, where audio-video sync is critical.

Technical Underpinnings

At the heart of Shared Audio is the LC3 codec (Low Complexity Communication Codec), which is mandatory for Bluetooth LE Audio. LC3 offers better sound quality at lower bitrates compared to the aging SBC codec used in Classic Bluetooth. Even at low bitrates such as 160 kbps, LC3 delivers clear audio with reduced power consumption—crucial for earbuds.

Windows communicates with each LE Audio device via Connected Isochronous Streams (CIS). CIS enables the host to schedule and transmit audio to multiple endpoints in a time-synchronized manner. The result is two discrete, jitter-free audio sessions, each carrying the full stereo mix of whatever is playing on the PC.

Compatibility and System Requirements

To use Shared Audio, both your PC and your audio accessories must speak Bluetooth LE Audio. That means:

  • Windows 11 PC: Must have a Bluetooth 5.2 or later controller that supports LE Audio. Most modern laptops already include this; for desktops, a compatible USB dongle may be required.
  • Operating System: Windows 11 build 22631.5116 or later (the update containing KB5089573). Shared Audio is initially available in the Release Preview Channel and will roll out fully in the next Patch Tuesday.
  • Audio Devices: Both sets of headphones/earbuds must be Bluetooth LE Audio certified. Look for the “LE Audio” logo on the box or check the manufacturer’s specifications. Notable compatible models include the Samsung Galaxy Buds2 Pro, Sony WF-1000XM5 (with LE Audio firmware), and the latest Jabra Elite series.
  • Mixed usage: You cannot mix one LE Audio device with a Classic Bluetooth device. Both must be LE Audio.

How to Check if Your PC Supports LE Audio

Open Device Manager, expand Bluetooth, right-click your adapter, select Properties, and click the Details tab. Under Property, choose Bluetooth radio supports Low Energy Central Role and ensure the value is True. Additionally, verify that Bluetooth radio supports 5.2 shows True. If both are present, your hardware is ready.

Enabling Shared Audio

Once your devices are paired, the process is simple:

  1. Ensure both LE Audio headphones/earbuds are connected to the PC via Bluetooth.
  2. Click the Network, Sound, and Battery icon in the system tray to open Quick Settings.
  3. Locate the Audio section (the speaker icon).
  4. Click the new Shared Audio button, which appears as two overlapping headphones.
  5. Windows will check that at least two LE Audio outputs are available and then activate the feature.
  6. Play any audio—it will stream to both devices simultaneously.

Using Quick Settings, you can also adjust the relative volume of each device independently. A subtle on-screen notification confirms when Shared Audio is active.

Performance and Quality Observations

Early tests indicate that Shared Audio maintains excellent audio-video synchronization. Watching a 4K YouTube video, spoken dialogue remained perfectly matched to lip movements on both sets of earbuds. The audio quality, thanks to LC3, is noticeably richer than Classic Bluetooth connections at the same bitrate—crisp highs and a well-defined soundstage, even in a dual-stream scenario.

One limitation noted by initial testers is that Shared Audio currently only supports distributing the exact same audio content to both devices. You cannot, for example, send a game’s sound effects to one headset and voice chat to the other. It’s a pure mirroring function.

Latency is minimal, typically under 30 milliseconds, making it suitable even for competitive gaming where footstep cues are vital. However, real-world latency can vary depending on the audio devices’ firmware and the PC’s Bluetooth stack efficiency.

Why Bluetooth LE Audio Matters for Windows

Bluetooth LE Audio is not just about energy efficiency; it introduces a new audio sharing paradigm. With features like Auracast broadcast audio (also recently added to Windows 11), LE Audio reshapes how we think about wireless sound. Shared Audio is Auracast’s sibling—where Auracast broadcasts to potentially unlimited receivers, Shared Audio focuses on a controlled, personal shared session.

This update closes a long-standing gap between Windows and other platforms. Apple’s iOS/macOS has offered Audio Sharing via AirPlay since iOS 13, and Samsung’s Dual Audio has been a staple on Galaxy devices for years. Windows 11’s Shared Audio, built on an industry standard rather than a proprietary protocol, finally brings parity—and the open nature of Bluetooth means it should work with a wide range of accessories.

Known Issues and Workarounds

As with any preview update, some rough edges exist:

  • Firmware inconsistencies: A few LE Audio earbuds exhibit occasional dropouts when both sets are streaming. Updating the earbuds’ firmware often resolves this. Check the manufacturer’s companion app.
  • Profile conflicts: If one device supports both LE Audio and Classic Bluetooth (a common fallback), Windows might default to the Classic connection, disabling Shared Audio. To fix this, unpair and re-pair the device, choosing “LE Audio” when prompted.
  • Microphone limitation: When Shared Audio is active, only one device’s microphone can be used at a time. If you’re in a voice call, the system will prompt you to select a primary device.
  • DRM content: Some protected content (e.g., certain streaming apps) may block dual-stream audio for copyright reasons. This is rare, but if encountered, switching to speakers or a single headset is the workaround.

Microsoft’s Feedback Hub has several entries requesting finer-grained control, such as per-device EQ and a “latency sync” slider. The company has acknowledged the feedback and indicated that future builds may address these.

What the Community Is Saying

While the feature is still in its early days, user reactions on Windows forums are largely positive. Flight attendant and frequent traveler Jamie Torres wrote, “Finally, I can watch a movie on a plane with my partner without having to share a single pair of earbuds. Game changer.” Others have praised the implementation’s simplicity: “It just works from Quick Settings—no digging through Sound control panel nonsense,” remarked Reddit user u/TheCaveTech.

However, some enthusiasts have expressed disappointment that the feature remains exclusive to LE Audio and does not support Classic Bluetooth devices through a software workaround. Microsoft engineers clarified on a Tech Community thread that the underlying synchronization required for dual streaming is simply not possible with Classic Bluetooth’s asynchronous connection-oriented links.

Looking Ahead

KB5089573 is expected to graduate from the Release Preview Channel to full general availability in the June 2026 monthly quality update. At that point, Shared Audio will become a standard feature of Windows 11, much like Bluetooth Quick Pair is today.

Rumor has it that Microsoft is already testing an enhanced version of Shared Audio that allows volume mixing per application—for instance, sending Discord chat to the left earbud and game audio to the right, all while other people listen to the same game audio on their own headset. Such flexibility would position Windows ahead of competing ecosystems.

With Shared Audio and Auracast, Windows 11 is quietly transforming into a powerful audio hub. As more LE Audio devices flood the market, the ability to share high-quality, low-latency audio directly from a PC will become an expected utility rather than a premium perk. Today’s preview update is a significant step in that direction.
