3. Check that your Sony SRS XB21 Did Indeed Reset
Next, power on the unit again, as detailed in step 1 above.

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.
