The Logitech UE 9000 provides rich and clear sound. The high-resolution driver produces a spacious soundstage and a remarkable level of clarity. It can connect wirelessly to up to multiple Bluetooth®-enabled devices at once—phones, tablets, computers. Switching between devices is as easy as pressing pause on one and pressing play on another. A long-life battery keeps the beat steady and strong. Plus, our active noise canceling technology filters out ambient noise for an immersive listening experience.
