Wireless headphones, such as AirPods, can cause a serious risk to the health of its users, said Jerry Phillips, a professor of biochemistry at the University of Colorado (USA).
"My concern for AirPods is that their placement in the ear canal exposes the tissues of the head to relatively high levels of radiofrequency radiation," said the expert, who referred to tumors and other conditions associated with abnormal cell function.
The danger that such a device could represent, of course, is not limited to the Apple product. According to Phillips, current data raise "potential concerns for human health around the development of all technologies operate on radio frequencies."

His warning comes after some 250 doctors and scientists from more than 40 countries, including Phillips himself, signed a petition to the United Nations and the World Health Organization, in which they express their "great concern" by the uses of the non-ionizing electromagnetic field, which is the type of radiation emitted by wireless devices, including Bluetooth technologies.
The petition indicates that according to "numerous recent scientific publications", electromagnetic fields can cause cancer, neurological disorders and DNA damage. In addition, the document findings from the International Agency for Research on Cancer, which determined that the aforementioned fields are "possibly carcinogenic" to humans.
However, not all scientists share those concerns. According to Kenneth Foster, professor of bioengineering at the University of Pennsylvania (USA), by combining and analyzing all the research on electromagnetic fields you can see a clear absence of damage of any kind.
The specialist also said that neither the World Health Organization nor other institutions of that nature have found "any clear evidence of health hazards at exposure levels below international limits."
