Welcome to the world of ultimate ears. Hear your music like never before with this Logitech Ultimate Ears Wonderboom 984-000840, the super-portable Bluetooth speaker with surprisingly big sound that is clear, crisp, and full of big, beautiful bass. And even better, with 10 hours of playback and a completely waterproof design, you can take it anywhere. Go from picnics in the park to binge-watching shows with Furry friends; from the beach to the shower and back without missing a beat. And if you need to really turn things up, quickly pair two together for even more sound.
