Loud and clear
The MEGABOOM 4 delivers a powerful, clear and room-filling 360° sound with thunderous bass. It is even bassier than the previous generation. Ultimate Ears' signature sound is carefully balanced to ensure you can hear every note.

Spacious 360° sound
Featuring our legendary cylindrical design, specially engineered to deliver room-filling, stereo quality sound that radiates evenly in all directions.

Throbbing bass
MEGABOOM 4 uses softer passive coils than the MEGABOOM 3, which means that the passive coils work in the lower range. The music sounds bassier and fuller without exaggerating or distorting.
