Bluetooth headset is also wireless 2.4G, which may interfere with aircraft communication. ? First of all, of course, Bluetooth headsets can be taken on the plane, but they can't be used when they are taken on the plane, because all electronic devices including Bluetooth headsets must be turned off during the take-off and landing phases of the plane; Although some electronic devices can be turned on during flight, such as notebooks, tablets, cameras and so on. The mobile phone must be turned off all the time. You can wear a Bluetooth headset, but you can't connect the mobile phone.

China can't use it. When flying, electronic devices such as mobile phones, tablets and charging treasures must be carried with you, and it is forbidden to put them in the suitcase. Moreover, both the charging treasure and the mobile phone should be turned off, and the mobile phone is turned off instead of in flight mode, so the Bluetooth function cannot be used.

Some foreign countries are ok, depending on the attitude of the civil aviation authorities in the country where the airline is located and the airline itself.

Theoretically, if the product has a lithium battery, it should be carried with you. Because if the battery is abnormal, such as fever, odor or spontaneous combustion, it can be found as soon as possible. This is very dangerous when consigning items with batteries. Therefore, everything about lithium batteries should be carried with you.

Knowing this principle, you will know that batteries are not allowed to be inspected. There is a battery in your Bluetooth headset. So I can't check. If you want to check the suitcase, you should keep the Bluetooth headset with you. Of course, the headphones must be turned off. I believe you know the principle. No other wireless communication equipment is allowed on the plane.

Bluetooth headset avoids the winding of earphone cable, makes people move more freely and brings people a more convenient and comfortable listening experience. But recently, the British "Daily Mail" published that Bluetooth headsets may be harmful to human health.

Dr Joel Moscovitz, a professor of public health at the University of California, Berkeley, said that research shows that the cerebrovascular barrier is an important organ to prevent chemical toxins from entering the body, and sending radio waves to the ears for a long time will weaken the vascular barrier of the brain. Using Bluetooth headset is equivalent to putting a microwave transmitter next to the brain, which is harmful to health.

In this regard, Professor normand Laperriere of the Canadian Health Network Medical Center said that although there is no evidence in the existing research that there is any direct relationship between mobile phones, headphones and tumors. However, this is probably due to the lack of research time, and its impact may only appear in the next few years or decades.
