Logitech Stereo Speakers Z120 make it simple to connect just about any audio source. They receive audio through a standard 3.5 mm plug and get power from the USB port, so no wall plug is required. You can easily enjoy your favourite music, videos and more. With integrated power and volume controls, it's a snap to get the sound you want. The compact size doesn't take up a lot of room on your table or desk, so it's easy to move your speakers from room to room. And the cable management system helps eliminate cord clutter.
