How to Factory Reset Sony SRS XB33

Show you how to factory reset your Sony SRS XB33 portable wireless speaker to its default settings.  Factory resetting restores the XB33 to default state. Plus, it erases any earlier paired Bluetooth devices from memory. Clearing these stops this speaker from pairing to any nearby Bluetooth devices. Also, you might factory reset to get it ready for sale or re-gifting, or to stop it from syncing wirelessly with devices you no longer wish it to connect with.

The speaker may make a ding-dong tone sound when it powers up and announce that it has paired, should it connect to a in-range device. Or it may make no sound at all if not.  But whether the unit pairs or not though, this factory reset routine works the same way, as follows.

2. Press and Hold the Pairing 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.

4. Done with How to Factory Reset Sony SRS XB33 !

The factory reset is now complete. So you may safely sell or gift the 33, or pair it again with your favorite Bluetooth devices.

After a factory reset, the XB33 no longer automatically syncs with any previously joined Bluetooth device. Thus, to restore auto pairing, you manually connect it with a device. Then, any time that both speaker and that device have Bluetooth turned on, and they’re near to each other, pairing automatically takes place once more.
