How to Reset Sony SRS XB21

Show you how to reset your Sony SRS XB21 to its default settings.  Resetting restores the 21 to default state. Plus, resetting erases any earlier paired Bluetooth devices from its memory. Clearing these stops the 21 from pairing to any nearby Bluetooth devices. Also, you might reset to get it ready for sale or re-gifting, or to stop it from pairing wirelessly with devices you no longer wish it to connect with.

How to Reset Sony SRS XB21: Step by Step

1. Turn the Unit ON

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

Then, the status light comes ON.

The 21 may make a ding-dong tone sound when it powers up, should it connect to a nearby device. Or it may make no sound at all if it does not.  Whether the unit pairs or not though, this reset routine works the same way, as follows.

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

Find these buttons as shown next.  They are both on the top button panel, as we point out in the next picture.

The XB21 then enters reset mode.

Then after a miniscule pause, the 21 powers OFF, and the status lamp goes dark, as shown next. Note that on the SRS XB21, there is no power-down sound.

3. Check that your Sony SRS XB21 Did Indeed Reset

Next, power on the unit again, as detailed in step 1 above.

Note that after reset, the XB21 comes up in discovery mode. The Pairing Mode lamp fast flashes white to let you know this.

This is a signal that you may then look for this speaker on a nearby BT device, and pair to it if you so desire.

4. Done with How to Reset Sony SRS XB21 !

The reset is now finished. So you may now sell or gift it, or pair it again with your favorite Bluetooth devices.

After a reset, the XB21 no longer automatically links with any previously paired Bluetooth device. Thus, to restore auto connecting, you manually pair it with a device. Then after that, any time that both speaker and that device have Bluetooth activated, and they’re near to each other, pairing would automatically take place once more.
