How to Connect Sony SRS X3 to Alexa

This post shows how to connect the Sony SRS X3 Bluetooth brick speaker to Alexa smart speakers. Since this pairing happens between the Sony and Echo devices directly, you need not turn Bluetooth on in the mobile device you’re using to set up this connection.

How to Connect Sony SRS X3 to Alexa, Step by Step

With your X3 switched OFF (the Power lamp is dark), run through this routine to connect it to your Alexa Echo, Show, Studio, Input, and Dot models. We use an iPad Air tablet to set this up.

1. Find the Alexa app on your Mobile Device

We found the app on the iPad Air as shown in the next shot. In this exercise, the app is in a custom folder we set up, called Smart Speakers, pointed at by the green arrow.

The Alexa App Icon in Folder on iPadOS.

2. Run the Alexa App

The app displays its Home screen as we see in the next screenshot.

3. Tap the More Item to Continue with How to Connect Sony SRS X3 to Alexa

Find the hamburger item in the lower right corner of the screen. We point at this with the green arrow in the last screenshot.

This brings up the Alexa app’s main menu, as shown in the next screenshot.

4. Tap the Settings Option on the Main Menu

The Settings option is pointed at by the green arrow in the last photo.

This brings up the Settings screen, as shown in the next screenshot.

The Device Settings item on the Settings Page of the Alexa App on iPadOS.

5. Tap the Device Settings Option

Touching Device Settings brings up the All Devices page, as we show next.

From here, choose which Echo device you wish to pair with the X3.

6. Tap the Alexa Device you Wish to Connect

This takes you to the device-specific settings screen for the speaker you chose.

In this demo, we’re pairing from our Thomas’s 2nd Echo Dot 4 speaker to our 300, and so, its device specific settings screen looks as follows.

7. Tap the Connect a Device Item

Find the Connect a Device option pointed at by the green arrow in the last screenshot.

This brings up the Setup screen, as we show next.

The Pair Bluetooth Device Setup page on the Alexa app on iPadOS.

At this point, your Alexa device scans for nearby Bluetooth devices that are in pairing mode. Here, we selected an Echo Dot 4 earlier. So, this speaker will be the one that scans for BT devices.

Note that our Dot speaker found no devices so far. But it will in the next steps, when we turn on the X3 and put it in pairing mode.

8. Power Up the Sony SRS X3

Bring your speaker close to your Alexa device to pair, and power up that speaker by pressing and releasing the Power button as we show in the next picture.

This light should then start glowing green.

And the X3 plays a startup chord.

9. Place the BT Speaker into Pairing / Discovery Mode

Put your speaker into discovery mode by pressing and releasing the Pairing button. Find this button as we show in the next picture. It’s on the top of the speaker, in the front row of buttons, second one in from the left.

When this discovery mode begins, the speaker plays two high beeps, and the Pairing lamp starts fast flashing white.

10. Find the Sony SRS X3 on the Alexa App SETUP Page

When you put the speaker into discovery mode, it should then appear in the Alexa app, on the Pair Bluetooth Device… page, as we see next.

Note that if your speaker does not show up on this page at this point, then try moving it very close to the Alexa speaker, closing and restarting the Alexa app, and then repeating steps 3 through 7 along with step 9 above. We usually find that this gets the speaker to appear here as it should.

11. Find your Sony SRS X3 on the Discovered Devices List

See the last screenshot above. Our test speaker is there.

12. Finally, Connect your Alexa with your Sony SRS X3

Pair to the speaker by tapping its corresponding entry on the Pair Bluetooth Device… screen, we see in the last screenshot above.

Your Alexa speaker then pairs with the Sony.

The app then takes you back to the Thomas’s 2nd Echo Dot 4 screen, which looks something like the following.

Note that our speaker now shows as connected. Note though that the X3 makes no sounds when a Bluetooth device connects to it. So you won’t hear one when the Echo Dot connects to it either.

The X3 is now connected with your Alexa smart speaker. Its Pairing light glows solid white to signal that successful pairing is in effect.

13. Done with How to Connect Sony SRS X3 to Alexa !

We can now ask Alexa to play music or news, and those programs will come out of the 3. Be sure though, to speak to the Echo speaker when making requests, and not the BT speaker. Even though the Sony SRS X3 is now joined with Alexa, the Echo is still the speaker that hears your voice commands through its internal far field microphones.
