Wireless headphones whilst listening to music can be bad for your health

"Wireless headphones whilst listening to music can be bad for your health" If you think about it the fact that the receiver is constantly near your head and brain... transmitting and receiving radio signals constantly.. surely this isn't good for your health over a long period of time. We have all heard how mobile phones can be detrimental to health through radio signals... wireless headphones that are always trying to pickup signals and are never off your head surely then are a bad idea and not good for your health... Why not just not risk it and instead get some wired headphones instead which dont have the risk! Listen to music safely i say and to no risk to your health...
