How to Hard Reset Sony XB 21

Show you how to hard reset your Sony XB 21 Extra Bass portable BT speaker to its default settings.  Hard resetting restores this version of the Sony XB series speaker to its default state. Plus, hard resetting erases any earlier paired Bluetooth devices from memory. Then this wiping stops this speaker from pairing to any nearby Bluetooth devices.

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

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

4. Done with How to Hard Reset Sony XB 21 !

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 factory reset, the XB 21 no longer automatically syncs with any previously paired Bluetooth device. Thus, to restore auto pairing, you manually sync 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.
