Big Bass in Full 360

14-hour battery life
Forget the charger. WONDERBOOM 4 bangs longer with 14 hours of playtime. So you can focus on having a good time.

Dust and water resistant
The awe-inspiring IP67 rating gives WONDERBOOM 4 the durability to withstand dust, dirt, and even a splash or two. It can even get submerged in water for 30 minutes, making it the perfect compadre for the pool, beach, trail, or shower.

Drop-Proof with serious range
It’s built to take 5-foot drops. And with 40 meters (131 feet) of wireless range, you’ve got freedom to explore—even when the road gets tough.

Pair two for serious stereo
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.
