This gadget functions like a headset, but in retro fashion. We all know that our phones cause major exposure of radiation to our bodies. Studies are still going on trying to prove whether the radiation has any effects on our body. The World Health Organization has stated that there has been no convincing evidence to prove that radiation from phones has an effect on our health or can be a cause for cancer. There’s lost of studies going on and they all contradict each other, whether you believe the studies or not, radiation is bad period. I try using a headset as often as possible, it’s better to be safe then sorry.
