The Sandberg KidPhone is a smart headphone set, with a size and  shape adapted for a child’s head. The headphones sit tightly and do not  fall off as standard headphones often do. The headband is comfortable  and easy to adjust for the right size. The set uses a single cable to connect  to an audio source such as a computer or Discman. It also includes  an adapter for connecting it to a stereo system. The volume can be easily  adjusted using the inline volume control.  Not suitable for children under the age of three.
