Each portable speaker is capable of outputting a big, clear, crisp 86 decibels of 360-degree sound so it's loud enough to liven up any party or to just chill out. Enjoy it in the rain, around the shower or in the tub! Each UE Wonderboom is powered by Bluetooth allowing you to connect up to 100ft (30M) away without your music dropping out. Seamlessly control your music from across the room. The UE Wonderboom lasts for up to 10 hours on a single charge, so you can listen for longer.
