USO has a robust and stylish design which moves the impression of a handset as technical device into the background.
USO features high-quality, great sound, and has been tested thousands of times across the world. As an additional option it is made with a switch for the user to choose between two languages or different audio clips.
The USO handset base is made from a PVC synthetic material. The standard colours are black, dark grey and white. The cable is available in various lengths and it is particularly durable thanks to the flexible steel tube.
