Dear ALL

now i understand how the IR wireless headphone works but i have a small ques. now IR must have a line of sight so you will be looking to the IR transmitter so the IR enter your eye?? so is it that danger ??

thanks
 

No its not a danger. The IR light energy is not focused. It is spread across a wide area. It the same as a TV remote, there is no danger pointing a TV remote at someone. Now, if you too a laser and modulated it to produce a wireless headphone, that would be a different story.

In life, there are no absolutes. Nothing, even water, is 100% safe all the time. You can read the following:

This document describes the safe IR level for eyes. The system they were using was large scale IR LEDs for illumination. This is a much higher output than the small level used to modulate information.
