Hours of wonder
WONDERBOOM 4 bangs longer with up to 14 hours of playtime. So you can soak up every moment and keep the party going.
Beats dust, splashes ...and it floats
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.
Double up 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 (note: it doesn't connect with WONDERBOOM 1 or 2, BOOM, MEGABOOM, or HYPERBOOM).
A real road warrior
It's built to take 5-foot drops (it's been drop-tested from 1.5m). And with 40 metres of wireless range, you've got freedom to explore, even when the road gets tough.
Pair it up easily with Google Fast Pair
In one tap, the WONDERBOOM 4 enables quick, effortless Bluetooth pairing with your Android devices (requires Android phones running Marshmallow and above/6.0+).
