Storing the speaker in a cool, dry place when not in use is beneficial. Regularly updating the firmware via the app can include battery optimization improvements. Consider turning off the speaker completely when prolonged use isn’t anticipated.

Troubleshooting Common Issues
Experiencing connection problems? Ensure Bluetooth is enabled on your device and the speaker is in pairing mode. If sound distortion occurs, lower the volume or check for obstructions near the speaker. For volume issues, verify the volume is maximized on both the speaker and your connected device.
If the speaker won’t power on, try a different charging cable and adapter. Resetting the speaker to factory settings via the app can resolve software glitches. Regularly check for firmware updates, as these often address known bugs and improve performance. Contact support if issues persist.
Bluetooth Connection Problems
If your UE Boom 3 won’t connect, first confirm Bluetooth is active on your smartphone or tablet. Ensure the speaker isn’t already connected to another device – it can only actively pair with one at a time. Try “forgetting” the speaker in your device’s Bluetooth settings and re-pairing it.
Move closer to the speaker; range can be affected by obstacles. Restart both your device and the speaker. Check for interference from other wireless devices. If problems continue, reset the speaker to factory settings through the UE Boom app for a fresh start.
Sound Distortion and Volume Issues
If you experience sound distortion with your UE Boom 3, lower the volume on both the speaker and your connected device. Excessive volume can cause clipping and a distorted sound. Ensure the speaker’s surface is stable; vibrations can impact audio quality. Check for obstructions near the speaker’s drivers.
Within the UE Boom app, experiment with the customizable EQ settings to fine-tune the sound profile. If distortion persists, try a different audio source or cable (if applicable). A factory reset via the app can resolve software-related audio problems.

Comparison with JBL Flip 5
The UE Boom 3 and JBL Flip 5 are both excellent portable Bluetooth speakers, but differ in key areas. The Boom 3 boasts 360-degree sound, while the Flip 5 offers a more directional audio experience. UE’s speaker is known for its ruggedness and floating capability, exceeding the Flip 5’s water resistance.
JBL often delivers a slightly more powerful bass response. Battery life is comparable, around 10-12 hours. The Boom 3 integrates with the UE Boom app for EQ customization and multi-speaker pairing, features less prominent in the JBL Flip 5 ecosystem.
UE Boom 3 vs. UE MegaBoom 3
The UE Boom 3 and MegaBoom 3 share core features – ruggedness, waterproofing, and 360-degree sound – but differ significantly in size and power. The MegaBoom 3, as the name suggests, is larger and delivers substantially louder, bass-rich audio, ideal for larger gatherings.

The Boom 3 is more portable and compact, perfect for individual use or smaller groups. While both benefit from the UE Boom app’s features, the MegaBoom 3’s increased size accommodates a larger battery, offering extended playtime. Price-wise, the MegaBoom 3 commands a premium.
Safety Precautions and Warnings
