The black Z207 Bluetooth Computer Speakers from Logitech is designed to deliver stereo sound at your desk wirelessly. Connect up to two devices via Bluetooth 4.1 or a single device with the included 3.5mm audio cable. With the Z207's integrated Logitech Easy-Switch technology, you can direct which source you want your audio play from. If you need to step away from your work with your device in hand, these speakers have a 20m wireless range, so you won't have to interrupt your streaming.
