Sony XB 21 Hard Reset Instructions

Sony SRS XB21 front view with its lights glowing.

We give Sony XB 21 hard reset instructions to return this Extra Bass portable party speaker to its factory default settings. Hard resetting restores this model of the XB series Bluetooth speaker to fresh-out-of-the-box state. Plus, doing this erases any earlier paired Bluetooth devices from memory. Then this clearing stops the XB 21 from pairing to any nearby Bluetooth devices. Further, you might hard 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.

Sony XB 21 Hard Reset, Step by Step Instructions

1. Turn the Speaker 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, as shown next.

The speaker may make a ding-dong tone sound when it powers up, should it link to a nearby device. Or it may make no noise if it does not do so. But whether the unit pairs or not, this hard 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 -Power- and -Volume Down- buttons.

The XB 21 then enters hard reset mode.

Then after a mini pause, the unit turns OFF, and the Power lamp goes dark, as shown next. Note that on the XB 21, there is no shutdown sound.

3. Check that your Sony XB 21 Did Indeed Hard Reset

Next, power up the unit again, as explained in step 1 above.

Note that after hard reset, the XB 21 comes up in discovery mode. The Pairing Mode lamp blinks quickly to let you know this.

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

4. Done with Sony XB 21 Hard Reset !

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

After a hard reset, the XB 21 no longer auto syncs with any previously paired Bluetooth device. Thus, to restore auto linking, 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.
