Can I use the Magic Button for one-touch access to all of my playlists?
You can play, pause and skip tracks directly on the speaker with any music service. Or you can use the BOOM & MEGABOOM app to program and navigate custom one-touch playlists for Apple Music and Deezer Premium.
Can I use the Magic Button to control all of my music if I don’t use Apple Music or Deezer?
Yes. You can always use Magic Button for basic music controls: pause, play and skip. The music controls work with any music service.
Do I need an app to use the Magic Button?
No. To use the Magic Button to pause/play/skip, you don’t need to download the app. However, to use the Magic Button for one touch access to your playlists, you need to download the Ultimate Ears BOOM & MEGABOOM app by Ultimate Ears.
Does the speaker float in water?
Yes, it floats and it’s completely waterproof.
Can the speaker connect with other Ultimate Ears speakers?
Yes. BOOM 3 can connect with BOOM, BOOM 2, MEGABOOM and MEGABOOM 3 using the Party Up feature in the BOOM & MEGABOOM app. It cannot connect with BLAST or MEGABLAST.
