Are Bluetooth earphones harmful?

Are bluetooth headphones safe? Bluetooth devices emit low levels of nonionizing radiation. Exposure to low amounts of this type of radiation is not harmful to humans. According to the Food and Drug Administration (FDA), routine exposure to nonionizing radiation is “generally perceived as harmless to humans.”
