Factory Reset JBL Wonderboom

Front view of the Wonderboom 1.

Here, we show the factory reset JBL Wonderboom procedure, to return it back to its factory default settings. The factory reset routine on the Ultimate Ears Boom line of wireless speakers works as detailed next.

Resetting the JBL Wonderboom wipes any earlier paired Bluetooth devices from their internal memory. Thus, clearing this data prevents the speaker from pairing to any nearby Bluetooth devices after the factory reset. Further, you might reset the unit to ready it for sale or re-gifting. Or, perhaps you simply wish to stop it from pairing with devices you no longer use with it whenever you power it up.

Factory Reset JBL Wonderboom: Step by Step

1. Turn on the JBL Wonderboom

Press and release the Power button. The status lamp in that button then lights and you hear a power-up sound. We’ve circled the Power button in the next picture.

Then, the status light comes on solid or it blinks, as shown next.

The glowing -Power- button.

2. Wait for the Power Up Sound

The JBL Wonderboom makes a unique electronic sounding noise when it turns on. The unit is then ready for use when this sound ends. Note that the speaker may or may not pair with a device. Indeed that depends on whether you have any in-range Bluetooth devices that know about the UE and that it has previously paired with as well. Whether paired or not, the factory reset works the same way, as follows.

3. Be Sure the Speaker is Not Paired with Anything, to Continue with Factory Reset JBL Wonderboom

This speaker does not respond to the factory reset request while paired with a source Bluetooth device. So, unpair it before factory 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 speaker, near the front. Volume DOWN is the long vertical line on the front, near the bottom. See these both pointed out by the green arrows in the next picture.

The JBL Wonderboom then enters factory reset mode.

Then, within a couple seconds, the unit powers off after factory reset completes. The falling electronic ker-plunk sounds, and the status lamp in the Power button goes dark again.

5. Check that your JBL Wonderboom Did Indeed Factory Reset

Next, power on the speaker again, as described in step 1 above.

Then, the JBL Wonderboom UE comes up in ready-to-pair mode, with the pairing lamp rapidly flashing white.

6. Done with Factory Reset JBL Wonderboom !

The JBL Wonderboom UE factory reset is finished now. So go ahead and gift or sell it, or pair it anew with your favorite Bluetooth devices.

After a factory reset, this speaker no longer automatically connects with any previously paired Bluetooth device that happens to be in range and in pairing mode. So to restore automatic BT pairing, you need to manually pair it with your desired device(s). Then after that, any time that both the JBL Wonderboom and that device have Bluetooth turned on and are close enough to each other, pairing automatically takes place again.

Now don’t forget to delete any now-stale connections to the JBL Wonderboom from your source Bluetooth devices that you set up prior to factory resetting. These will no longer work. So you’ll want to “forget” them in your source device’s Settings pages.
