Microsoft has started rolling out a see of a include called “shared audio” in Windows 11. It lets a PC send the same sound stream to two Bluetooth/L.E. sound gadgets at the same time (for illustration: two earphones, two earbuds, or two speakers).

Specifically:
The include is built on Bluetooth Moo Vitality (LE) Sound, a more up to date form of Bluetooth sound innovation that bolsters higher-quality sound, lower inactivity, more control proficiency, and vitally different synchronized sound streams.

In the Windows 11 see, you’ll discover this beneath Fast Settings: when you have backed Bluetooth LE sound gadgets associated, you ought to be able to select “Shared sound (preview)”, at that point select two yield gadgets.
The Verge

The see is constrained to certain equipment (for presently). Microsoft calls out “Copilot Furthermore PCs” (certain models of the Surface Portable workstation and Surface Professional) and a few consistent headsets.
The Verge
Thus, if you’ve ever needed to share what you’re hearing on your PC (a motion picture, music, etc.) in two remote earphones at once, Windows is moving toward making that local and much less hacky.
Why it matters
Here are the key reasons this include is significant:
Better shared tuning in experience
In the past, if two individuals at the same PC both needed to utilize remote earphones, you had to utilize workarounds (wired splitters, extraordinary apps, third-party virtual sound cables). Presently: local bolster implies less complications, less required pieces of equipment or software.
Advances in Bluetooth LE Audio
LE Sound isn’t fair a showcasing term: it bolsters highlights more seasoned Bluetooth sound didn’t. For illustration: different get gadgets can tune in from a single transmitter (or one source). It too underpins made strides effectiveness and inactivity.

Keeps pace with versatile devices
Phones (Android & iOS) have upheld dual-headphone (or multi-headphone) sharing for a whereas. Windows catching up implies equality: if you need to observe a motion picture on a tablet with a companion, each of you can wear remote earphones and both tune in to the same thing. The Windows encounter is getting to be more device-friendly.

How it works (in preview)
Here’s a harsh diagram of how to utilize the highlight presently (and what you’ll require). Since it’s see, subtle elements may evolve.
Requirements
A PC running Windows 11 Insider See (Dev or Beta channel) that incorporates the shared sound highlight.
The Verge

A Bluetooth connector in the PC that underpins Bluetooth LE Sound (regularly implies Bluetooth 5.2 or afterward) also legitimate drivers. The gadget moreover needs to back the related “Auracast” or LE Sound broadcast/streaming capabilities.
Windows Central

Two (or more) remote sound gadgets (earphones, earbuds, speakers) that back LE Sound and are consistent with the PC’s transmitter. For case, the see notices a few congruous gadgets: Samsung System Buds 2 Professional, Buds 3/3 Master, and Sony WH-1000XM6.
The Verge
Usage steps (general)
Pair and interface both remote sound gadgets to your Windows 11 PC by means of Bluetooth (as you would normally).
In Speedy Settings (the sound symbol on the taskbar), see for an choice like “Shared sound (preview)”.
Select the two (or more) gadgets you need to yield to, at that point hit “Share” (or identical) and sound ought to start gushing to both.
The Verge

Playback a movie/music and affirm both gadgets are accepting the same sound, and check for potential delay/latency.
What you ought to test
Sync: Are both earphones in match up (no recognizable slack between them)?
Audio quality: Does one gadget drop in constancy, or does gathering affect bitrate or codec?
Volume/level adjusting: Are both gadgets able to be controlled independently?
Connectivity steadiness: Does one drop out, or do you lose association on gadget switching?
Distance/range: Since you presently have two remote joins, check if one loses association sooner than usual.
Impact on other Bluetooth gadgets: Now and then spilling to two gadgets can constrain transfer speed or affect other Bluetooth use.
Current impediments and things to watch
Because this include is still in see, there are a few caveats and restrictions to keep in mind:
Hardware & gadget back is constrained. Fair since you run Windows 11 doesn’t ensure this highlight will show up. Your PC’s Bluetooth connector and drivers must bolster LE Audio/related profiles. Numerous existing PCs may as it were back more seasoned Bluetooth classic sound (A2DP) and not LE Sound.

Older Bluetooth headsets may not work. If the headphones/earbuds you utilize don’t bolster LE Sound (or back as it were classic Bluetooth), you may not advantage from this include (or it may drop back to bequest mode).
Latency and match up issues stay conceivable. Indeed with LE Sound, when spilling to different yields there is a chance of one gadget slacking behind the other (particularly if the two gadgets have diverse inside buffering).
Software/hardware drivers matter. If your Bluetooth driver is more seasoned or your PC’s connector is not optimized, you may get destitute execution, dropouts, or glitches.
Until presently, Windows as it were permitted one sound yield gadget at a time for framework sound, so a few apps or workflows may accept that—changing this may uncover bugs. Already, the as it were ways to yield to two gadgets at once included workarounds like utilizing “Stereo Mix” or virtual sound cables.

If both gadgets aren’t LE Audio-compatible, or if the PC doesn’t bolster numerous yield streams in equipment, it can come up short. For case, string discourses point out that numerous PCs basically don’t bolster two Bluetooth sound streams at once.

Background: Why this was difficult before
To appreciate this highlight, it makes a difference to get it how Bluetooth sound has worked truly and what changed.
Bluetooth classic audio
Traditionally, Bluetooth sound on PCs (and numerous gadgets) has utilized the A2DP profile for high-quality stereo sound, and HFP/HSP profiles for mic/handset utilize (calls). The issue: PC Bluetooth connectors were frequently optimized for a single stereo sound yield at a time. Numerous Bluetooth stacks basically weren’t outlined to transmit the same stream to different gadgets concurrently. For case, per Microsoft’s documentation:
“For sound, you can not tune in with two Bluetooth gadgets at the same time. … You would require a Bluetooth splitter.”

Also:
“You can not tune in with two Bluetooth gadgets at the same time… You would require a Bluetooth splitter.”

So the capability was viably lost or exceptionally limited.
Workarounds
Because of that impediment, individuals used:
Wired splitters (plug two wired earphones into one jack).

Virtual sound driver computer program (e.g., Voicemeeter) to course sound to different yield gadgets.

Some Bluetooth earphone models that upheld “dual-connect” themselves (earphone to earphone) but that’s distinctive than PC gushing to two gadgets.
Tom's Equipment Forum
Enter LE Audio
Bluetooth LE Sound presents modern profiles (e.g., the LC3 codec) and highlights such as broadcast sound (one source to numerous sinks) and multi-stream sound (one source to different recipients) additionally made strides effectiveness. Since of these, supporting two (or more) yield gadgets gets to be doable. Windows presently riding that wave.
What this implies for clients (counting you)
Here are commonsense implications:
For movie/music sharing
If you and a companion need to observe a film on your Windows 11 PC and both utilize remote earphones, this shared-audio include is idealize. Both of you can tune in wirelessly, no splitter, no stuck with one set of earphones or one wired and one wireless.
For gaming or collaborative listening
If you’re playing a diversion or tuning in along in two partitioned earphones (perhaps one individual is gushing chat and the other is fair tuning in to music), you can do that more cleanly. Too supportive for gushing setups, substance makers, or shared workstations.
For audio-in/monitoring setups
If you’re a substance maker, performer, podcaster, etc., being able to send the blend to numerous remote earphones (to screen what’s being listened) is useful. Already you might have had to wire them, but remote includes flexibility.
For compatibility & buy decisions
If you’re buying modern remote earphones (or a PC) and arrange to utilize dual/headphone-sharing highlights, you presently need to check for LE Sound back (and multi-stream bolster) or maybe than fair accept “Bluetooth sound works with everything”. Since more seasoned models may not back the required features.
For troubleshooting
If the highlight doesn’t work on your PC:
Check your Bluetooth connector: does it back LE Sound / Bluetooth 5.2+?
Check your earphones: do they bolster LE Sound? Producer ought to list it.
Make beyond any doubt you’re on a Windows 11 adaptation that incorporates the shared-audio see (both OS construct and PC show may matter).
Update Bluetooth drivers.
In case one gadget slacks, attempt moving the gadgets closer to the PC or turning off other remote impedances sources.
If you’re still stuck, you can drop back to computer program workarounds (VOICEMEETER, Stereo Blend) but they may include more manual setup and may not back culminate match up for two remote devices.
Example test situation: How I would assess it
If I were to test this include on my possess Windows 11 PC, I’d take these steps:
Verify equipment & OS
Confirm Windows 11 Dev/Beta and that the “Shared audio” choice appears up in Fast Settings.
Check Bluetooth connector in Gadget Supervisor — is it LE Audio-capable? (e.g., Bluetooth 5.2)
Ensure my earphones are combined and bolster LE Audio.
Pair two consistent headphones
Pair Headset 1, make beyond any doubt it’s associated and working.
Pair Headset 2, guarantee it’s associated and working.
Test each exclusively: play sound, check latency/quality.
Activate shared sound feature
In Fast Settings, discover “Shared sound (preview)”.
Select both yield gadgets. Hit “Share”.
Play sound (a motion picture or soundtrack).
Evaluate
Do both earphones get sound at the same time?
Is there a discernible delay between them? (e.g., hearing a press in one and at that point the other)
Does exchanging sound (pause/play) remain in sync?
Is there any drop in volume, fidelity?
Does one earphone disengage or involvement clipping when the other is active?
Does the PC’s Bluetooth or CPU stack spike significantly?
Distance test: how distant can each earphone go absent some time recently sound drops out?
Other Bluetooth gadgets: if I’m moreover utilizing a Bluetooth mouse/keyboard, is there interference?
Fallback test
If the include falls flat, attempt the ancient “Stereo Mix” workaround: empower Stereo Blend, select “Listen to this device” etc. See how that compares (but note more seasoned impediments with Bluetooth).
