Ultimate Ears Wonderboom 2 Factory Reset

Here, we list the Ultimate Ears Wonderboom 2 factory reset routine steps, that return the unit to its default factory settings.

Factory resetting wipes any paired Bluetooth devices from memory. Furthermore, clearing this data stops the unit from auto linking to any nearby devices afterwards. Plus, you might factory reset to ready it for sale or re-gifting.  Or, perhaps you just want to stop it from pairing with devices you no longer listen to on it when you power it up.

Ultimate Ears Wonderboom 2 Factory Reset: Step by Step

1. Turn on the Ultimate Ears Wonderboom 2

Press and release the  Power  button.

The status lamp in that button then lights up, and you hear a power-up sound. E.g. We circled the  Power  button in the next picture.

2. Wait for the Power Up Sound

The Ultimate Ears Wonderboom 2 makes an interesting electronic sounding noise when it boots.  When you hear this, the unit is then ready for use.

Now the 2 may or may not pair with a device.  This depends on whether you have any in-range Bluetooth devices that know about the Wonderboom 2.  But whether paired or not, the factory reset works as follows.

3. Be Sure the Ultimate Ears Wonderboom 2 is Not Paired with Anything Prior to Factory Reset

This speaker may not respond to the factory reset command while synced with a source Bluetooth device. So disconnect it before resetting.

4. Press the  Power  and the   Volume DOWN  Button Together for Five to Eight Seconds

Find the  Power  and Volume DOWN   buttons.  The   Power button is on the top of the unit, near the front.  Volume DOWN  is the long plum line on the front, near the bottom.  See these both pointed out by the green arrows in the next picture.

The Ultimate Ears Wonderboom 2 then enters the factory reset process.

Next, the falling electronic ker-plunk sound plays.

Then the lamp in the  Power  button goes dark.

Finally, within a couple seconds, the unit switches off.

5. Check that Factory Reset of Ultimate Ears Wonderboom 2 Did Indeed Occur

Next, power on the 2 again, as detailed in step 1 above.

After factory reset, the unit comes up in ready-to-connect mode, with the Pairing lamp rapidly flashing white.

6. Done with Ultimate Ears Wonderboom 2 Factory Reset !

The factory reset program concludes now. So go ahead and gift or sell, or connect it anew with your BT devices.

Finally, don’t forget to delete any now-stale connections to the Wonderboom 2 from your source BT devices that you set up before factory resetting.  Why?  Because these will no longer work since the linkage data for them is now gone from the speaker. Thus you should “forget” them in your source device’s settings pages.
