Ultimate Ears Wonderboom 4 Bluetooth Standalone Speaker Cobalt Blue

Introduction

WONDERBOOM 4
Ultraportable Bluetooth® speaker with that notoriously bigger sound that’s extra-crispy and fully loaded with big bass. Blast it indoors and out. Now with Podcast Mode, specially tuned for crisp, clear vocals.

Get that big, bassy stereo sound—all from one little speaker. Tap the Outdoor Boost for audio that’s specially tuned for the great outdoors.

Check out the new EQ mode specially designed for crisp, clear vocals, so podcasts sound great.

WONDERBOOM 4 bangs longer with 14 hours of playtime. So you can soak up every moment and keep the party going.

The awe-inspiring IP67 rating gives WONDERBOOM 4 the durability to withstand dust, dirt, and water. It’ll even float in water. Take it to the pool, beach, trail, or shower.

All you gotta do is pair up two. Press once to double up. Press again for a full two-channel stereo assault—that’s left and right channels blasting from each respective speaker.

(Doesn’t connect with WONDERBOOM 1,2, BOOM, MEGABOOM, or HYPERBOOM)

It’s built to take 5-foot drops. And with 40 meters of wireless range, you’ve got freedom to explore—even when the road gets tough.

In one tap, the WONDERBOOM 4 enables quick, effortless Bluetooth pairing with your Android devices.

Plastic parts in WONDER­BOOM 4 include a minimum of 31% certified post-consumer recycled plastic by weight. “Post-consumer” means it’s made with plastic sourced from end-of-life electronics. So it’s literally the life of the party.
