Powerful, balanced audio performance is delivered by the Ultimate Ears BOOM 4 portable Bluetooth speaker, engineered for immersive sound and rugged outdoor use. A cylindrical design is used to produce spatial 360° sound that radiates evenly in all directions, ensuring consistent audio coverage in any environment. Deep, accurate bass is generated without distortion, while dual active drivers and passive radiators work together to maintain clarity at both low and high volumes. Whether used indoors or outdoors, a bold and dynamic listening experience is consistently provided.
Durability and portability are combined with smart functionality to support active lifestyles. An IP67 rating ensures the speaker is waterproof, dustproof, floatable, and drop-resistant, allowing use in demanding conditions such as beaches, pools, and outdoor adventures. Extended listening is supported by up to 15 hours of battery life on a single charge, while PartyUp technology allows multiple compatible Ultimate Ears speakers to be wirelessly connected for a larger, more immersive soundstage.
