Why Buy?
Big Sound, Zero Worries — Wherever You Take It
The Ultimate Ears Wonderboom 4 is the kind of speaker you grab without thinking twice — tough enough for anywhere, and loud enough to actually impress.
Despite its compact size, it pumps out full 360-degree sound that fills a room, a backyard, or a campsite with ease. You get a solid 14 hours of playback, so it'll comfortably last a full day out without needing a recharge. Outdoor Boost kicks things up a notch when you're outside and background noise creeps in, while Podcast Mode gives voices extra clarity — handy if you like catching up on your favourite shows while you cook or potter around the garden.
It's built for real life — waterproof, dustproof, and it actually floats, so a splash at the pool or beach is no drama. The compact shape tucks easily into a bag, and the simple controls mean there's no fussing around. If you want more sound, pair two together for proper stereo. It just works, and it looks great doing it.

- You love music or podcasts while cooking, relaxing, or entertaining
- You need all-day battery without carrying a charger
- You want big sound from something small enough to throw in a bag
