An iPhone with a Sony SRS XB20 speaker.
Gives Sony XB 20 reset instructions to return this wireless speaker to its default settings. Resetting restores the 20 to new-out-of-the-box state. Plus, it erases any earlier paired BT devices from its memory. This stops the speaker from pairing to any nearby devices. Further, you would reset the unit to get the unit ready for sale or re-gifting, or to stop it from pairing wirelessly with devices you no longer wish it to connect with.
Press and release the Power-Pairing button for a half-second or so. Find this button as shown in the next picture.
Then, the Power-Pairing button lights up, as we see next.
The speaker may make a two-tone sound as it boots, to announce that it has paired, should it sync to a nearby device. Or it may play no sound at all if it does not. But whether the unit links or not though, this reset routine works the same way, as follows.
Find these buttons as shown next. They are both on the top button panel, as we point out in the next picture.
The XB 20 then enters its reset firmware program.
Then after about five seconds, the speaker shuts OFF, and the Power-Pairing button goes dark, as shown next. At that time, release the buttons. Note that on the XB 20, there is no power-OFF noise.
Next, power on the unit again, as detailed in step 1 above.
Note that after reset, the XB 20 comes up in pairing mode. The Pairing Status lamp quickly blinks white to let you know this. But the speaker should not sync with any device fresh after a factory reset.
E.g. See this in the next picture.
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.
This operation is now complete. So you may now sell or gift the speaker, or pair it again with your favorite Bluetooth devices.
Note that after reset, the XB 20 no longer automatically links with any Bluetooth device. So to restore auto joining, you manually pair it with a device. Then after that, any time that both speaker and that device have Bluetooth turned on, and are in range, pairing would automatically take place once more.
