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 XB 21 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.
