Therefore, manypeople agree that the Bluetooth headset can fix the problem easily. Moreover,the Bluetooth headset takes many other conveniences for us in the daily life.We can do other things when weare talking with some one on the phone through the Bluetooth headset. Forexample, we can write email or do house working when you are making the callwithout the boring wire. Besides, I think most of the people met such asituation: you are driving when the call rings, you want to answer the call,but it is dangerous to do that when you are driving, and it is illegal on thelaw, and many accidents are caused by this.

When we are answering the phone, we always keep the mobile phone closeto our ear, a long time later; you will feel ache from the arm and neck. If theconversation keeps long time, you will feel headache.The electromagnetic wave of the Bluetoothis lower than the cell phone, and we just need put the cell phone into our bagwhen we are dialing or answering the call.

It can not remove theradiation directly, but it can separate the radiation pollution from our body,so that we can avoid the harm from mobile phone. According to theinvestigation, the radiation from the Bluetooth is equal to one tenth ofradiation from the mobile phone. Therefore, I think, compared with the mobilephone, the Bluetooth headset will take less harm for our health.Compared with the mobile phone, the Bluetooth headset can reducethe radiation. But it also takes certain harm for our health if you often useit.

Besides, long-term wearing headset will make your sprit keep nervous,which is harm for our health.Every coin has twosides; we should make use of its advantage and try to avoid the disadvantage.The Bluetooth headset plays an important role in our daily life, but we needcontrol the boundary between the advantage and disadvantage.
