Our Verdict

Ultimate Ears BOOM 4

Ultimate Ears MEGABOOM 4

The Ultimate Ears BOOM 4 and Ultimate Ears MEGABOOM 4 are very similar speakers, both in looks, durability and app support. The BOOM 4 is smaller and easier to take along with you, and it gets a bit louder, but it sounds noticeably less clear with veiled treble, which you can EQ. In contrast, the slightly larger size of the MEGABOOM 4 allows it to reproduce more bass frequencies that the BOOM 4 can't even with EQ and its battery is rated to last longer.
