Today, Mytour will show you how to play audio simultaneously through two separate Bluetooth speakers. For Mac users, you can use the built-in tool to stream music through any two speakers from any manufacturer. On Windows, the two devices you want to use must be capable of pairing with each other (typically two speakers of the same model).
Steps
On macOS

Pair the Bluetooth speakers with your Mac. If you haven't done so already, follow the provided instructions to pair the speakers with your computer.



Click on the Go menu at the top of the screen.

Select Utilities from the dropdown.

Double-click on Audio MIDI Setup. This will open the ″Audio Devices″ window.

Click the + button located below the left panel. A short menu will appear.

Choose Create Multi-Output Device from the menu. A list of speakers will appear in the right panel.

Select both Bluetooth speakers. To do this, check the box to the left of each speaker's name. The selected speakers will play audio from your Mac simultaneously.

Rename the new multi-output device. Renaming the speaker pair is helpful as it makes the device easier to locate in the sound settings later. To do this, double-click the Multi-Output Device option in the left column (near the bottom) and enter ″All Bluetooth Speakers″ (or a similar name).

Set the speakers as the Mac's audio output. The final step is to configure the Mac to route audio through the speaker pair. Here's how:
- Click the Apple menu and select System Preferences.
- Click Sound.
- Select the Output tab, which is the second tab near the top of the window.
- Click the name you assigned to the speaker pair (e.g., ″All Bluetooth Speakers″).
On Windows

Turn on the Bluetooth speakers. To use two Bluetooth speakers simultaneously with a Windows computer, the speakers must be capable of pairing with each other. This typically means they need to be from the same product line, though some models from the same manufacturer may also work together.
Pair both speakers with your Windows computer.

Use the speaker manufacturer's app (if available) to pair the speakers together. Some speaker manufacturers provide Windows-compatible apps that allow you to connect multiple speakers. If your device comes with such an app, open it and check for options related to connecting multiple speakers (sometimes labeled as ″multiple outlets″).

Open Windows sound settings by:
- Clicking the Windows search icon (a circle or magnifying glass next to the Start button).
- Typing audio into the search bar.
- Selecting Manage audio devices from the results.

Choose Speakers and click Set Default. This option is located near the bottom of the window.
- If the ″Set Default″ button is unavailable, it means the speakers are already set as the default audio output. Proceed to the next step.

Click the Recording tab. This is the second tab at the top of the window.

Right-click on Stereo Mix. If you don't see this option, right-click on an empty area of the window and select Show Disabled Devices. The option will then appear.

Click Enable. This action will configure the computer to use stereo sound instead of mono.

Select Stereo Mix and click Set Default. A green and white checkmark will appear next to the ″Stereo Mix″ option.

Select Stereo Mix again and click Properties. This option is located to the right of the ″Set Default″ button you clicked earlier.

Click the Listen tab. This is the second tab at the top.

Check the box labeled ″Listen to this device.″

Select the second speaker from the ″Playback through this device″ menu. This is the speaker that is not currently set as the default.

Click OK.

Click OK again. The sound settings dialog will close.

Restart your computer. After the computer reboots, you will be able to hear stereo sound simultaneously through the two paired Bluetooth speakers.
