I'm a big fan of FPS. I want to get a good gaming headset so I can use it for CoD and Battlefield to play online. However, there is a dilemma that is making me reluctant to buy the gaming headset. There have been reports that extensive use of cell phone can lead to increase chance of developing brain tumor. Since a person will use a gaming headset for a longer period of time compare to using a cell phone, it would seem like a gaming headset would have even a higher chance of developing brain tumor. Can somebody address my concern? Thanks.
