Get great sound throughout the room with Logitech’s Pure-Fi Express Plus Speaker Dock for your iPod or iPhone. The Pure-Fi Express Plus features omnidirectional acoustic technology, which provides great sound at a more consistent level throughout the room. It also includes the ability to run on AC or battery power, which–along with an integrated handle–makes it easy to take your music from room to room. Other features include a clock with alarm, so you can rest assured that you?ll wake on time; and a wireless remote control that works from up to 30 feet (10 meters) away, and stores neatly in an integrated compartment.
