How to Pair Sony SRS XB21 Bluetooth Speaker

This post shows how to pair the Sony SRS XB21 Extra Bass wireless speaker by way of Bluetooth to common portable devices. E.g. These  include the iPhone, iPod Touch, and the iPad line of Apple phones, media players, and tablets.





How to Pair Sony SRS XB21

With your SRS XB21 powered OFF (power button is dark), run through these directions to pair it to your source BT mobile device. We’re using an iPad Air computer for this demo.

1. Go to the Home Screen on your Source Device

Firstly, press the Home button to reveal the smart device’s Home screen.

2. Find the Settings App

We found ours on the second page of the Home screen, as shown next.

3. Bring up the Settings App

Thirdly, touch the Settings app icon.

The smart device then shows the first page of its settings, as shown in the next step.





4. Go to the Bluetooth Settings  Page to Continue with How to Pair Sony SRS XB21 

Our Bluetooth Settings screen displays as follows. Note that our Bluetooth is enabled here. But since our Sony SRS XB21 is currently shut OFF (is not in Bluetooth discovery mode), it does not show up in the Bluetooth devices list. Also, we don’t see it since we’ve never paired this speaker with our mobile device before.

Turn on the speaker by quickly pressing its  Power-Pairing  button. See this, pointed at by the cyan arrow, in the next picture.

The unit then powers up, and its status lamp glows white, as seen in the next picture.

But since our tablet does not know about this speaker, the SRS XB21 will not pair with it automatically.

6. Put the Speaker in Pairing Mode

Now, to see your XB21 on your device, place it into Bluetooth discovery / pairing mode. To do that, press and hold the Power-Pairing button, and release when you hear the rising pitch beep sequence and the speaker announces, “Bluetooth pairing,” in a lady’s voice. Find the Power-Pairing button as pictured above.

In addition to the voice announcement,  the Bluetooth Status lamp begins flashing fast.
