In theory, the optimal distance to use a bluetooth headset depends on the headset itself, bluetooth chip, bluetooth version and so on.The higher the bluetooth version, the farther away the transmission is supported.But does not appear the connection breakpoint, the influence calls the effect, the voice is not clear, moreover also does not hear clearly.
What is the distance to use the bluetooth headset?Another important determinant of bluetooth headsets is the distance they are transmitted, regardless of the bluetooth version, but depending on the bluetooth technology PowerClass.Most mobile phones and mobile devices now use PowerClass2, a standard transmission distance of 10 meters;The upgraded PowerClass1 will increase the transmission distance to 100 meters, and both versions support A2DP stereo transmission protocol, which can be connected to stereo headphones.Generally speaking, the distance between mobile phone and bluetooth headset is not too far. If there is no big obstacle in the middle, the transmission quality is very good within 7 meters, and the breakpoint will appear if the distance exceeds 8 meters!Over 10 meters the connection between bluetooth devices will be lost.
According to the feeling of actual use, the distance between the phone and bluetooth headset is proportional to the noise of the conversation;In addition, when using stereo bluetooth headset to enjoy music, do not be too far away from the phone, otherwise it is easy to appear intermittent phenomenon.In addition to functional considerations, the appearance of bluetooth earphones and wearing comfort is also the key consumers must pay attention to when buying.Now there are many consumers at any time to hang the bluetooth headset in the ear, so the shape has become a basic condition;But each person's ear shape is different, the user must try to wear the comfort level before buying, then decides to buy;The person that wears glasses needs to notice more, the part that the ear of a lot of bluetooth earphone hangs an ear and glasses leg conflict, must try belt hind just knowing.
Generally speaking, the effective distance between bluetooth headset and mobile phone can reach 10 meters, and some enhanced adapters can reach 10 meters, but this refers to the maximum distance between mobile phone and bluetooth headset without obstacles.Affected by the environment, the actual effective communication range is only 2 ~ 8 meters;With the voice dialing function of the mobile phone, voice dialing can be directly carried out in the headset. In addition, the voice volume control and the last call number redial function of the headset are quite convenient to use.
Another important point of bluetooth headset is the transmission distance. The wholesale of bluetooth headset is not related to the bluetooth version, but depends on the bluetooth technology PowerClass.Most mobile phones and mobile devices now use PowerClass2, a standard transmission distance of 10 meters;Generally speaking, the distance between mobile phone and bluetooth headset is not too far. If there is no big obstacle in the middle, the transmission quality is good within 7 meters, and the wholesale of bluetooth headset exceeds 8 meters, there will be a breakpoint!Over 10 meters the connection between bluetooth devices will be lost.At present, bluetooth version 4.0 bluetooth headset on the market supports 20-meter calls, and 15-meter calls can be fully supported in fact.Distance according to the actual feeling of use, the distance between the phone and bluetooth headset is proportional to the noise of the call;In addition, when using stereo bluetooth headset to enjoy music, the wholesale of bluetooth headset should not be too far away from the mobile phone, otherwise it is easy to appear intermittent phenomenon.A correct understanding of the distance between bluetooth headsets can help reduce radiation hazards and improve the effectiveness of phone calls.You can also enjoy the function of listening to music better.
