Sony SRS XB43 Factory Reset

Gives factory reset directions for the Sony SRS XB43 Bluetooth speaker. Factory resetting restores the XB43 to factory default settings. E.g. Returns sound mode and light settings to their fresh-out-of-the-box values.  Plus, it clears any earlier connected Bluetooth devices from memory. Erasing these stops this speaker from pairing to any nearby BT devices. Also, you might factory reset to get this device ready for sale or re-gifting. Or perhaps you just want to stop it from pairing with devices you no longer have interest in.

Sony SRS XB43 Factory Reset: Step by Step

1. Turn the Speaker ON

Press and release the Power button for a half-second or so. E.g. Find the Power button as shown in the next picture.

Find the Power button, as shown in the last picture above.

Then, the status light comes on, as shown next.

The XB43 may make a ding-dong tone sound and say, “Bluetooth connected.” when it powers up. Or it may make no sound if it does not auto pair.  But whether paired or not, this factory reset works the same way, as follows.





2. Press and Hold the Pairing and Volume DOWN Buttons Together

Find these buttons as we show next.  Both of them are in the top button panel.

The XB43 then begins factory reset.

After one or two seconds, the unit shuts OFF. So the status lamp and party lights (if enabled) all go dark. Note that on the XB43, there is no power-off sound.

3. Check that your Sony SRS XB43 Speaker Did Factory Reset

Next, turn on the unit again, as outlined in step 1 above.

Note that after factory reset, the XB43 comes up in discovery mode. The Bluetooth Status lamp blinks blue in a pulse-pulse-pause-pulse-pulse-pause pattern, to let you know this. E.g. See this in the next picture.

This is a signal that you may then find this speaker on a nearby BT device. So you can pair to it if you so desire.

4. Done with Sony SRS XB43 Factory Reset !

With the factory reset now complete, you may now safely sell or gift this speaker. Or pair it again with your own Bluetooth devices.

Keep in mind that after a factory reset, the XB43 no longer automatically connects with any device. Thus, to restore auto pairing, you manually pair it with a device first. Then whenever both speaker and that device are in range, auto pairing takes place once more.
