Smartphone maker Apple is launching AirPods wireless headphones around the world, and from a small number of wireless headset users, it is now emerging as a fashion trend that has penetrated the lives of modern people, and other manufacturers are increasingly entering the Bluetooth headset market.
Similarly, wireless music listening is becoming more and more popular. This is because listening to music wirelessly can lead to clutter in the headphones. This is to prevent the cable from getting stuck.
Headphones inserted into the ear can cause the highest levels of damage to the head tissue, such as RF (Radio Frequency), said Dr. Jeffrey Phillips, a biochemist at the University of Colorado in the United States.
In addition to Dr. Phillips, 250 researchers from 40 countries have previously submitted reports to the World Health Organization (WHO) and the United Nations to testify. However, “Bluetooth-connected devices” only serve to confirm the health effects of magnetic fields, such as the non-ionizing radiation found in any smartphone or Bluetooth device.
This raises the question of whether the sale of wireless headphones means that they have not been screened for health risks. The answer is no. The US Federal Reserve has found that using headphones to transmit radio signals via a smartphone does not transmit radio waves to the ear, but only to the area outside the ear.
In addition, the radio frequency transmitted via Bluetooth is only 1 in 10 times that of a smartphone. “Instead of worrying about radio waves, Bluetooth should be more concerned about smartphone radio waves,” said Dr. Canafa, a professor of biomedical engineering at the University of Pennsylvania in the United States. This shows that talking for long periods of time using a wireless headset like Bluetooth is less of a health concern than talking on the phone for long periods of time.
