Researchers such as Dr. Jerry Phillips, Professor of Biochemistry at the University of Colorado, Colorado Springs, and Joel Moskowitz, Director of the Center for Family and Community Health at the University of California at Berkeley, are two of many researchers who are sounding the alarm about potential dangers of AirPods and similar Bluetooth devices.

“My concern for AirPods is that their placement in the ear canal exposes tissues in the head to relatively high levels of radiofrequency radiation,” said Dr. Phillips in a interview with Medium. He warns that more research needs to be done of the long-term health effects of such radiation and the potential of damaging neurological effects as well as the risk of tumor development.

Radio waves in the 2.4 – 2.48 GHz frequency range is used by microwaves. Bluetooth also uses those frequency ranges to wirelessly transmit signals between devices.
