Experience your music like never before. The Wonderboom is a reliable accessory that brings the power of music to life. Enjoy clear, beautiful 360° sound with balanced bass. It's perfect for the bathtub – better than soap bubbles and squeaky ducks. The Wonderboom is completely waterproof. It floats and is ideal for showers, pools, beaches, muddy fields, and rainy days. Dirt rinses off easily, and it continues to play your favorite music. Whether at a picnic in the park or binge-watching a TV marathon, the Wonderboom offers you 10 hours of uninterrupted music enjoyment. Simple play, pause, and skip functions allow you to control your music directly from the speaker. By pressing the Ultimate Ears button on the top of the speaker, you can easily play, pause, or skip a song.

With two speakers, you can double the fun. If you think one Ultimate Ears Wonderboom speaker sounds good, you'll be blown away by the sound you get with two. The Wonderboom has been tested for drop heights of up to 1.5 meters and features a loop for easy attachment to a bag, bike, or backpack. It is waterproof and dustproof according to IP67, meaning it can be submerged in water up to 1 meter for 30 minutes.

The rechargeable lithium-ion battery provides up to 10 hours of battery life between charges via micro-USB. It can be paired with up to 8 Bluetooth-enabled source devices and connected to two source devices simultaneously. Enjoy wireless streaming from two Wonderbooms from one source. For audio playback, it supports smartphones, tablets, and other devices that use Bluetooth wireless and Bluetooth smart audio profiles. The mobile music playback range is up to 33 meters.
