This slim, lightweight design of the Logitech S150 speakers offers easy controls and easy installation for a comfortable listening experience. Compact, movable speakers allow you to easily adapt to your setting. The connection is simple and fast. Just connect the speakers to the computer's USB-A port. An orange LED lights up when the speakers are on. Disconnect the USB-A cable (120 cm) to turn it off. The speaker buttons are really simple: volume and mute.

They are light and easy to move around so you can customise your installation and get perfect sound wherever you are.
