Enjoy big, balanced 360° sound with the Ultimate Ears Wonderboom 4 Joyous. Outdoor Boost and Podcast Mode keep music and voices clear in noisy environments, while deep bass and 14 hours of battery life let you listen longer. IP67 floatable, water- and dust-proof construction resists harsh outdoor elements, and the attached bungee loop makes it easy to carry. Pair up to two Wonderboom 4 speakers for bigger sound, connect via Bluetooth (4.0/5.0/5.2) within a 40m range, and find a USB cable and Quick Start Guide included in the box.
