{MOVED TO OWN THREAD}

I've been getting headaches using a Sennheiser RS116 Wireless headset. The unit is fairly pricey, and I have tried all sorts of adjustments, but still getting headaches. I've tried wearing the unit loose, adjusting frequency with no luck.

I normally never get headaches and have no health conditions that could suddenly cause headaches. My headache appears the day after I have used the Sennheiser unit - usually for watching a movie (so that the volume does not disturb others).

As for the idiot talking about McDonald's coffee, get serious. I'm not looking to cash in from the onset of headaches - who in the hell would do that? I would like to know why these wireless devices cause headaches and if I should be avoiding other wireless devices around my home.
