ir cordless headphone circuit electronic

Infrared cordless headphone circuit electronic. Using this low-cost project one can reproduce audio from TV or other electronic devices without disturbing others. It does not use any wire connection between TV and headphones. In place of a pair of wires, it uses invisible infrared light to transmit audio signals from TV to headphones. Without using any lens, a range of up to 6 metres is possible. Range can be extended by using lenses and reflectors with IR sensors comprising transmitters and receivers.
