Are Wireless Bluetooth earphones Safe?

With the development of the economy and science and technology, more and more people like to wear Bluetooth earphones to do housework, drive or others job, fashion and convenience. However, while the wireless Bluetooth earphones bring convenience to humans, they will also consider whether it will be harmful. So, are wireless Bluetooth earphones safe? Does the wireless Bluetooth headset really have radiation?

Is Bluetooth earbud safe? Does it really have radiation?

When someone goes to Google search for possible risks with Bluetooth headset, they're told by Google as below:

1. Bluetooth earphone increases the risk of cancer.
2. Bluetooth headset can damage reproduction, nerves, and genes.
3. Bluetooth will increase glioma and glioblastoma, increases the chance of illness.
4. Bluetooth increases cellular stress, an increase in harmful free radicals.
5. Effects include increased cancer risk, cellular stress, increase in harmful free radicals, genetic damages, structural and functional changes of the reproductive system, learning and memory deficits, neurological disorders, and negative impacts on general well-being in humans.

When someone encounters these problems, they will ask if these are true?

We need to know what Bluetooth is? How does it work?

Bluetooth is a wireless communication technology protocol that uses radio waves of 2.4 GHz to 2.485 GHz to enable short-range digital communication exchange between fixed equipment, mobile equipment, and buildings.

Bluetooth can be divided into three types according to its power:

1. Bluetooth class 1 emitter max out at 100mW(rang:100 meters), That is,0.1W is 1/20 of the maximum power of the GSM mobile phone.
2. Bluetooth class 2 emitters max out at 2.5mW(rang:20 meters), That is,2.5mW is the common power level of Bluetooth headset.
3. Bluetooth class 3 emitters max out at 1mW(rang:10meter), That is, 1mW is 1/2000 of the maximum power of the GSM mobile phone.

All of the figures listed here are the power outputs at the source, and not at the receiver.
Bluetooth is a short-distance transmission mode. If the Bluetooth headset is close to the mobile phone, its power level is usually 2 or 3. Compared with the GSM main-frequency signal strength, the electromagnetic radiation caused by the Bluetooth part is relatively small.

In theory, any kind of electrical products will generate certain radiation during operation, and Bluetooth headsets are no exception. However, due to the very low power of the Bluetooth headset, the actual radiation generated is very small.
It has been determined that the radiation when using a Bluetooth headset is only a fraction of the former, and is almost negligible compared to not using a Bluetooth headset.
According to the results of the World Health Organization, the radiation of Bluetooth products has no effect on the human body.
The output power of Bluetooth products is only 1 milliwatt, which is one-millionth of the power used by microwave ovens. It is one-thousandth of the power of mobile phones (mobile phones), and only a small part of these outputs are absorbed by the human body.
Therefore, compared to directly using the mobile phone to answer the phone, the Bluetooth headset's radiation is even smaller, and children and pregnant women can use it with confidence.

While Bluetooth earphones have radiation, but at present, there are no clinical cases arising from the use of Bluetooth devices carcinogenic.
Bluetooth devices that appear on the market today are subject to international standards.
Products are not allowed on the market if they are not low in radiation and are not controlled to be harmless to humans.
