Try adjusting the tone or EQ control on your sound source to lower the bass level. This will allow you to play the music louder before clipping (distortion) occurs. You can also check to see if the Bass Boost function is enabled, and disable it by pressing the Bass Boost button to disable it.
If you cannot connect your audio device to UberTM Boom Ultra via Bluetooth:
If you experience audio dropouts while playing music from a Bluetooth device, this may be happening because your unit is trying to link to another speaker. This can occur if you power off a speaker that was linked to your unit or if you have just turned on your unit and it is in Stereo-LinkTM mode. To stop the audio dropouts, exit Stereo-LinkTM mode by pressing the Bluetooth button. Alternatively, you can wait for your unit to link to another speaker if there is one within range.
If you would like to stop your speaker from automatically linking when you power it on, make sure you press and hold the Play/Pause button for two seconds to exit Stereo-LinkTM mode before you power it off.
