How to Sync Ultimate Ears Wonderbooms Together

This piece explains how to sync Ultimate Ears Wonderbooms together so that two of them play the same audio content from a source Bluetooth device. In this example, we use one Wonderboom 1, and one Wonderboom 2 speaker to show how syncing two Ultimate Ears Wonderbooms works. You can indeed sync two Wonderboom 1’s, two Wonderboom 2’s, or, as we’re doing here, you can join a Wonderboom 1 with a Wonderboom 2 speaker.

How to Sync Ultimate Ears Wonderbooms Together: Step by Step

1. Power Up the Two Ultimate Ears Wonderbooms

We show the Power buttons on each of our Ultimate Ears Wonderbooms in the next pictures.

Press and release the Power button on the first one, and await the power-ON sound.

Then, press and release the Power button on the second Wonderboom, and again, wait for it to come on.

2. Sync the First Wonderboom with a Phone or Other Bluetooth Device

In this demo, we’ll first sync the Wonderboom 1 speaker with our iPad Air tablet. If you’re not sure how to join your Wonderboom to a Bluetooth source device, then see our How to Pair 1 Wonderboom Speaker post for details.

3. Press and Release the Play / Pause Button on the First Speaker to Continue with How to Sync Ultimate Ears Wonderbooms Together

Next, press and hold the middle (Play / Pause) area of the Wonderboom you just paired with your BT source device until the speaker makes a pairing noise and the pairing lamp begins rapid flashing. Here, our first speaker is the original Wonderboom (the first version of this series), and in the next picture, we show where to press.

4. Press the Play / Pause Button on the Second Wonderboom

Next, press and release the middle area of the second Wonderboom. In our case, this is the second version of the Wonderboom (Wonderboom 2), and in the next picture, we show where to press on this speaker, with the yellow arrow.

The speaker then makes a pairing sound and the pairing light just above the center button in the last picture, blinks briefly. Then, once this speaker connects with the first Wonderboom, the pairing lamp starts glowing steadily.

5. Done with How to Sync Ultimate Ears Wonderbooms Together !

Your two Ultimate Ears Wonderbooms are now synced together. Thus, when you play audio on your Bluetooth source device, you’ll now hear it through both Ultimate Ears Wonderbooms at the same time.

Note that each Wonderboom provides stereo sound, and this holds true even when you have two of them joined to each other. I.e. Each speaker provides stereo whether or not it’s paired to another Wonderboom. Thus it’s not the case that the first Wonderboom plays the left channel and the second plays the right. In fact, both Ultimate Ears Wonderbooms play both channels, in stereo.

Breaking the Connection

To break the sync between the two Ultimate Ears Wonderbooms, simply power down the second one. After that, the first one (the one that you connected with your Bluetooth device) continues playing.

Now powering down the first one will also break the connection between it and the second speaker, and the second speaker will stop playing. But this also breaks the syncing with the source BT device. So powering OFF the first speaker stops BOTH speakers, although the second one will still be powered UP until you turn it off.
