Description

Enjoy a 360-degree sound with the Ultimate Ears WONDERBOOM 4 Blue. You hear sound from every side of the speaker, so it doesn't matter where you sit to hear the music well. With the Outdoor Boost button, you can amplify the sound. This way, you can also hear it clearly when you're outdoors with a lot of ambient noise. If you're listening to a podcast, use the Podcast Mode so voices sound more clearly. The speaker has an IP67 certification, which makes it dustproof and water-resistant so you can easily use it by the beach or at the pool. You can listen to your music or podcasts the entire day, thanks to the 14-hour battery life. Connect a second WONDERBOOM 4 speaker for stereo sound.
