Once charged, press the power button to turn on the speaker. It will automatically enter Bluetooth pairing mode, indicated by a flashing blue light. Now, on your smartphone, tablet, or computer, enable Bluetooth and search for available devices. Select “Wonderboom 3” from the list to connect. A successful connection is confirmed by a solid blue light and an audible tone. You’re now ready to enjoy your music!
Powering On and Off

Operating your Wonderboom 3 is straightforward. To power on the speaker, simply press the large, circular power button located on the top of the device. Upon pressing, the button will illuminate, and the speaker will emit a brief chime, indicating it’s active and ready for connection. The Bluetooth indicator light will begin flashing, signaling pairing mode.
To power off the Wonderboom 3, press and hold the same power button for approximately two seconds. The indicator light will turn off, and a descending chime will confirm the shutdown. It’s important to fully power off the speaker when not in use to conserve battery life. Avoid disconnecting the Bluetooth connection without powering off, as this can lead to unnecessary battery drain.
Bluetooth Pairing Instructions
Connecting your Wonderboom 3 via Bluetooth is a simple process. First, ensure the speaker is powered on; the Bluetooth indicator will flash blue, signifying it’s in pairing mode. On your smartphone, tablet, or computer, navigate to the Bluetooth settings menu. Enable Bluetooth if it’s not already active, and the Wonderboom 3 should appear in the list of available devices.
Select “Wonderboom 3” from the list to initiate pairing. If prompted, enter the pairing code “0000” (though this is rarely required). Once successfully paired, the Bluetooth indicator on the speaker will turn solid blue. The speaker will remember previously paired devices, automatically reconnecting when in range. To pair with a new device, you may need to manually disconnect from existing connections first.
Connecting via USB-C

Bluetooth Connection Problems

Difficulty pairing your Wonderboom 3? Several factors can cause connection issues. First, ensure Bluetooth is enabled on your device and the speaker is in pairing mode (usually indicated by a blinking LED). Move the speaker closer to your device, eliminating potential interference from other wireless signals or physical obstructions.
If pairing fails repeatedly, try “forgetting” the Wonderboom 3 in your device’s Bluetooth settings and then re-initiating the pairing process. Restarting both the speaker and your device can often resolve temporary glitches. Confirm that the speaker isn’t already connected to another device. For persistent problems, check for firmware updates via the Ultimate Ears app.
Sound Distortion or Low Volume
Experiencing distorted audio or unexpectedly low volume with your Wonderboom 3? Begin by verifying the volume level on both the speaker and your connected device. Ensure the audio source isn’t inherently low in volume or compressed with a low bitrate. Try a different audio source to isolate whether the issue lies with the speaker or the original file.

If distortion persists at moderate volumes, reset the speaker to its factory settings (consult the Ultimate Ears app for instructions). Check for obstructions near the speaker’s drivers. Finally, ensure the speaker is placed on a stable surface, as vibrations can sometimes cause distortion. A full charge can also improve sound quality.
Battery Life and Charging Issues

Concerned about your Wonderboom 3’s battery performance or charging? Typical battery life is up to 14 hours, but this varies with volume and audio content. If the battery drains quickly, reduce the volume and avoid extreme temperatures during use and storage. Ensure you’re using a compatible USB-C charger and cable.
If the speaker isn’t charging, try a different USB-C port or adapter. A slow charge might indicate a faulty cable. Avoid using the speaker while charging, as this can impact charging speed. If issues persist, fully discharge the battery, then recharge it completely. Contact Ultimate Ears support if problems continue.
Maintenance and Care
To ensure longevity and optimal performance of your Wonderboom 3, regular maintenance is key. After exposure to saltwater or chlorine, rinse the speaker thoroughly with fresh water. Avoid abrasive cleaners; use a damp cloth for cleaning the exterior. Do not use compressed air to clean ports, as this can cause damage.
Store the speaker in a cool, dry place when not in use. Extreme temperatures can affect battery life. Regularly check the USB-C port for debris. Proper storage and gentle cleaning will help maintain the Wonderboom 3’s waterproof integrity and sound quality for years to come.
Cleaning Your Wonderboom 3
Keeping your Wonderboom 3 clean is essential for maintaining its performance and appearance. Begin by disconnecting the speaker from any power source. Use a soft, damp cloth to wipe down the exterior surface, removing any dirt or debris. For stubborn marks, a mild soap solution can be used, but ensure the cloth is only slightly damp, avoiding water entering the ports.
Never use abrasive cleaners, solvents, or strong detergents, as these can damage the speaker’s finish. Pay particular attention to the buttons and seams, ensuring they are free from grime. After cleaning, dry the speaker thoroughly with a clean, dry cloth before using it again.
Storage and Transportation
When storing your Wonderboom 3 for extended periods, ensure it is completely dry and clean.

Do not place heavy objects on top of the speaker during storage or transport. If transporting in a bag with other items, ensure it’s adequately protected. Regularly check the speaker for any signs of damage, especially after travel. Proper storage and careful transportation will help prolong the life of your Wonderboom 3.

Battery Health and Longevity
To maximize the lifespan of your Wonderboom 3’s battery, avoid fully discharging it frequently. It’s better to charge it when it reaches around 20-30% rather than letting it die completely. Avoid leaving the speaker plugged in for extended periods after it’s fully charged, as this can degrade battery health over time.
Store the speaker in a cool, dry place when not in use, as extreme temperatures can negatively impact the battery. Using the speaker at moderate volume levels can also help conserve battery life.
