The nice thing about science is that there is little space for speculation in old-grown domains such as electromagnetism.

In this very moment, when you sit next to many WiFi devices, probably in an urban region with many mobile phone cells and a that, you can forget about the effect of the magnetic field of the earth onto your body. It is just negligible.

I haven't looked into WiFi, since this was about static magnetic fields rather than fluctuating magnetic fields, although I have read about the increased incidence of gliomas (a type of brain tumor) caused by cell phone usage. Of course, that only happens when you hold a wifi source up to your head constantly. For this reason, I don't think that wireless headphones are a good idea.

One odd thing I've come across lately are accounts of the effect of MRI magnetic fields on depression. https://www.scientificamerican.com/article/do-mris-treat-dep....

Since ECT and other forms of brain damage have been shown to offer temporary relief from depression when endorphins are released in response to the damage, I wonder if MRIs have a similar effect.

Something you shouldn't forget is that the electromagnetic field decreases rapidly with spatial seperation from the sender (broadcaster). The relationship is actually 1/r^2, with r the distance. That is: Doubling the distance means only 1/4 of the electromagnetic field strength.

That's the reason why the cell phone in your pocket has a higher impact on your reproduction organs then on your brain. And why the cell phone tower (on average) has less impact on your body then probably any device in your room.

The wireless headphones are recieving most of the time, that's why they should put little harm on your brain. Better care about keeping your phone in a bag instead of your trouser pocket.
