Because trees don’t have outlets. Forget the charger—20 hours of battery life lets you live that wire-free, worry-free life and keep on partying.

Pair up EVERBOOM with all your Ultimate Ears buddies, like BOOM 3, MEGABOOM 3, HYPERBOOM, EPICBOOM and EVERBOOM.

Drop it up to 1 m. It’s dust proof, water proof, and can even float in water. Plus, it goes just about anywhere with 55 m of range. Use the carabiner to take it wherever you go. (*Drop-tested from 1 m.)

Tap the Outdoor Boost button and get that extra 1dB of sound—even out in nature. Experience the punchy bass and big sound anywhere. Android users can easily connect to EVERBOOM with NFC* pairing. (*NFC-compatible smartphones with Android 8.0 or later)

Play, pause, and skip tracks directly from your EVERBOOM, so you can forget all about your phone. Set up one-touch playlists on your favorite streaming platforms, such as Spotify®, Amazon Music for Android, and Amazon Music and Apple Music for iOS.

Your gorgeous voice has entered the party. Now you can be a true dance commander by broadcasting your voice over your EVERBOOM speaker. Just use the BOOM app. (*To minimize echo, keep your phone at least 4 meters from your UE speaker.)
