    The Ultimate Ears WONDERBOOM 4 is a compact Bluetooth speaker for people who want portable 360° sound at home or outdoors, with up to 14 hours of playback, Outdoor Boost, and an IP67-rated waterproof, dustproof, floatable design.

    Recommended For

    • People who want background music by a pool, at the beach, or in the shower: its compact, floatable, dust- and water-resistant design suits places where a larger indoor speaker may be awkward.
    • Listeners who move a small speaker between rooms or share audio in a kitchen, bedroom, or campsite: its 360-degree sound makes placement less critical, and its portable, rugged design supports taking it along.
    • Podcast and spoken-word listeners who want a portable speaker for casual listening around the house: Podcast Mode is designed for vocals, and reviewers found speech-focused content suits the speaker’s sound.
    • Travelers and outdoor users who prioritize a small, easy-to-carry speaker for walks, day trips, or camping: reviewers highlight its portability and outdoor suitability, though it is better suited to nearby listening than covering a large gathering.
