Wonderboom 2 Buttons and Codes Explained

In this Wonderboom 2 buttons guide, we detail all the buttons, ports, and lamps on the speaker.  We give button functions, meanings, and codes and combinations to press for the various functions. And we show where they are on the speaker with many pictures.

Wonderboom 2 Buttons: Summary

The Wonderboom 2 has five buttons on the top and front. Plus, there’s one USB port on the back behind a water tight cover.

There are also two lamps in the top buttons. The status lamp in the Power button glows in one color during normal operation. Then also it flashes to show speaker charging going on or pairing mode active. It changes color too when the battery is low.

Finally, we also find a lamp in the Bluetooth button that shows BT pairing status. It blinks when the speaker is in pairing mode, and glows steadily when a pairing is active.





Wonderboom 2 Buttons: Detailed Descriptions of Each

The Power Button

First off, the Power button switches the unit ON and OFF. This button also contains an LED that shows power and battery status.

When the speaker is ON, and the battery has at least a little charge, this lamp glows solid white.

But when the battery falls to too-low status, this lamp glows solid  red.  This means that it’s time to put the BT speaker on the charge before it shuts off all the way.

Bluetooth Discovery Pairing Mode Button

Next, we have the Bluetooth discovery mode button, as highlighted in the next picture. This is the smaller of the two raised panel buttons.

With the speaker turned on, press the  Bluetooth button for one to two seconds, then release.  This places the speaker into pairing / discovery mode. When in this mode, the speaker sends its name and other connection info over the BT radio spectrum. This allows nearby devices to find it and connect.

When speaker is in pairing mode, this button rapidly flashes white.  Then after the speaker connects, it stops flashing. The light then glows a steady white for several seconds. This indicates that pairing was successful.  Then, it switches OFF to save battery power.  It then stays OFF as long as the wireless connection continues.





Note though that the pairing button does not light up unless the speaker actually pairs with a device.  Again, it only lights prior to pairing, in discovery mode, and for a brief time after you establish pairing.

The Play / Pause Button

The Play / Pause  button is  not raised. But you can find its outline in the center of the speaker top as we show in the next photo.

How to Pause and Resume Playback

Quickly press near the center of the top island to stop audio play. Press and release again to resume playback.

Move Ahead in a Playlist

Finally, you can skip forward to the next song in a playlist with the Play-Pause button on the Wonderboom 2. As the song plays, do the following…

      • To advance to the next song, quickly press and release the Play-Pause button twice.  Upon doing that, your source device advances to the next song in the current playlist.

Volume UP and DOWN Buttons

The Wonderboom 2 has volume controls too.  What wireless speaker doesn’t?  Find these on the front.  These controls are shaped as large minus and plus symbols, They are cyan colored on our speaker.  They lower and raise the speaker loudness.

See the volume buttons, circled in yellow, in the next picture.  These buttons never light up. Plus, the easiest places to press to get them to work, are in the centers of the controls. We picture these next.

The Reset Button Combination Code

Turn the speaker ON but do not allow it to pair to anything.  Then press the  Volume Down (-)   and  Power buttons together. Hold them in for five to eight seconds.  Triggers a factory reset.

The Power Status Lamp

This LED light is dark when the Wonderboom 2 is OFF and not charging.  When powered ON, the status lamp glows steady white no matter whether the speaker is paired or not. Plus, It pulsates a dim-to-bright-to-dim pattern as the speaker recharges.  See the  Power  lamp in the next picture,

The Outside / Outdoor Mode Button

Pressing and releasing this button once changes the speaker’s frequency response.  It boosts mid range frequencies while lowering the higher treble and lower bass ones.





Find this button on the bottom, in the center of the unit.

Then outdoor mode is activated, this button lights up. This mode lets you hear the speaker better when far away from it. Furthermore, the reduced bass and high end response helps prolong battery life too.

To return the speaker to full audio response, press and release the button again.  The tree shaped lamp then goes off, and full response is then restored.

Wonderboom 2 Power Port Panel

The   USB Power   input port hides behind a sealed, flexible door. Find this on the back of the speaker, near its bottom.

You open this panel carefully, prying it open with a fingernail, coin, or other dull tool.  Avoid overly pointy prying objects. These can scratch the water seal around the flap edges, and thus destroy the water resistance.





The USB Power Input Port

This is a micro USB female plug, where your AC charger cord connects.
