The SILENT DISCO BOX HD9-RGB wireless headphone is specially developed for intensive use for
silent entertainment. The structural virtue and straightforward controls are clear characteristics of a
specified design. The headphone has three pre-programmed RF channels, which are easy recalled
with the control switch. For each RF channel, the LED lights up in a different color in the ear pads.
Besides the RF channel selection, the headphone is equipped with a volume control and a power
switch. Each headphone operates on an internal battery for about 8 hours. Charging the internal
battery only takes 3 hours. The adjustable headband makes a tight but comfortable fit, which makes
the headphone wearable for children from eight years old and up.
