Bluetooth headphones on the market now are mainly divided into three kinds of these Bluetooth headphones are also very common in our life. Communication Bluetooth headset, music Bluetooth headset and sports Bluetooth headset. The kind of hanging in the ear a flash a little thing is communication bluetooth headset, mainly used to make phone calls; music bluetooth headset more to head-mounted type, and sports bluetooth headset more for the ear hanging type, moisture-proof and sweat-proof, suitable for running and fitness when using. Previously, there are some did not use as well as less understanding of the Bluetooth headset friends that it is redundant, I think that such a point of view some prejudice; we do not exclude some unscrupulous manufacturers before the cottage goods as well as the shortcomings of these headset products, however, in the headset market is so competitive, those who do not do the product manufacturers have long been closed down; therefore, the Bluetooth headset industry now is still in a relatively benign Development stage. With the introduction of the new traffic law, bluetooth headset can be said to be a night of red (driving when picking up and playing a cell phone deduction of 2 points ah); more than a lot of media and netizens flirting with the traffic laws and regulations strict, bluetooth headset fire; and bluetooth headset in recent years, the overall sales of bluetooth headset also presents a slow and steady upward trend, these are all indicative of bluetooth headset from our lives closer and closer. Of course, bluetooth headset can not only help you in the car when you make a phone call, it also has a lot of usually you do not pay much attention to but very practical features. We all know that the cell phone is radioactive, this radiation for the brain is certainly not a good thing, we do not study how many brain cells it can kill; alone holding up a cell phone to play a 10-minute phone call is enough to make your arm sore, the ear is also very uncomfortable; I believe that this kind of feeling we all have it. The bluetooth headset is a good solution to this problem, it can keep my brain away from cell phone radiation, and no longer need to hold up the phone to make a call, the waist is not sore back pain, but also reduces the risk of cell phone falls.

With the introduction of the new traffic law, driving while answering a cell phone will be punished; in fact, points deduction is not the main purpose of the relevant departments, is to remind drivers to drive safely; and bluetooth headset in the introduction of the new traffic law has become exceptionally hot, to buy it most of the people are a family of cars. And in my daily work, I sometimes wear a Bluetooth headset, because then I can do the work in hand while answering the phone, two without delay. Bluetooth headset has a wide range of uses in daily life and work, and it can also bring you more convenience. Whether you are commuting to and from work on the subway, sports and fitness or pursuing fashion trends, Bluetooth headset has a wide range of applications in these areas, and has also been recognized by the vast majority of users.

I. Bluetooth version

Bluetooth version is an important aspect of the Bluetooth headset sound quality, the higher the Bluetooth version, the faster the signal transmission, the more stable, consumers in the process of talking and listening to the song, it will be less encountered signal disconnection, sound lag and other phenomena, for the time being, Bluetooth headset products on the market are generally used in the Bluetooth 4.1 version, some of the medium- and high-end products have been used in the Bluetooth 4.2, 5.0 version.

II. Bluetooth chips

Headset signal transmission effect is mainly determined by the chip of the headset, in addition to the chip whether it comes with DSP digital noise reduction technology, CVC echo processing technology, whether to support APT-X, AAC, LDAC and other technologies are also factors that affect the sound quality of the headset. In addition, different brands of chips in the performance is still a big difference, at present, CSR's Bluetooth chip in the performance of sound quality than the company's products such as Loda, Chuangjie better, consumers can try to choose to use the chip in the purchase of Bluetooth headset products.

Third, the headset cavity

Whether the acoustic cavity of the headset is scientific is also an important aspect to determine the sound quality of the headset, but due to the high cost of research and development, innovative discoveries and inventions are more difficult to achieve, few manufacturers to specialize in this area, therefore, consumers can not care too much about this aspect of the headset when buying.

IV. Headphone speakers

A large part of the sound quality of the headset is also determined by the speaker, while the speaker presented by the sound quality effect is determined by the magnets within the speaker, vibrating membrane, voice coil line, from the voice coil line used material, copper wire in the low and medium frequency is better, the sound quality and life of the sound generating unit is also better. From the speaker magnet type, neodymium iron boron magnet performance is far better than iron oxide magnet. Therefore, consumers try to choose the speaker using the above materials when shopping for headphones.

Factors affecting the sound quality of Bluetooth headphones are mainly the above, but many manufacturers in the Bluetooth headset market engage in false advertising, using shoddy components to pretend to be branded components, tempting consumers to buy at the same time in order to obtain higher profits. Therefore, before consumers buy, it is best to go to the physical store more audition, so as not to be deceived.

First of all, because the factory, bluetooth headset may be in the factory lag for a period of time, the internal consumption of a certain amount of power, bluetooth headset processing once the headset is not enough power can not be used normally, there will also be a sound, beeping sound; so be sure to use the bluetooth headset is fully charged, charging is generally displayed red light, 2-3 hours, the red light is off, that is, said that the charging is complete. Bluetooth headset processing this point, although simple, but also for many consumers eager to experience ignored, and even often people suspect that the Bluetooth headset is bad. In fact, it is not necessarily broken. One more point, before using, please make sure to read the instruction manual in detail, so that it may be better, the correct use of Bluetooth headset.

Then, inside the phone settings, turn on the Bluetooth function of the phone, and then a Bluetooth icon will appear on the screen. After you turn it on, a typical cell phone will prompt you if you are searching for a nearby

Bluetooth device, select "Yes". This is the cell phone began to search for nearby Bluetooth devices, Bluetooth headset processing at the same time the Bluetooth headset out, long press the Bluetooth headset on the top of the multifunctional power button for 5-8 seconds, until the Bluetooth headset on the top of the indicator light for the red and blue lights alternately flashing, or a color of the indicator light is always on (the pairing status of each type of headset is not the same, generally only these two situations) state. At this point, the Bluetooth headset device is truly searchable. Only then can the cell phone search the Bluetooth headset. After the phone searches for a Bluetooth headset, there will be a few seconds of time the screen is still, the upper display to find the name of the Bluetooth device; or display the name and model of the Bluetooth headset, Bluetooth headset processing and then select "connect to the device". At this time, there will be a prompt screen on the phone, let you enter the pairing code, generally speaking, Bluetooth headset pairing code is "0000" or "1234", the specific pairing code, please refer to the manual. After the pairing is completed, the phone will display a headset logo, at this point, the Bluetooth headset all complete pairing, you can use the Bluetooth headset to make a phone call or listen to songs. After the first pairing, the next Bluetooth headset automatically remembers the information without repeating the pairing action. Just need to turn on the Bluetooth function. The automatic pairing connection is completed after the power on.

In using a Bluetooth headset, I've found maybe a couple of little situations below:

1. After pairing and connecting, it will automatically disconnect in a few minutes, in this case, it is usually caused by the headset's insufficient power, and the internal city urging can not start normally. Suggestions, immediately turn off the bluetooth headset, start charging 2 hours, and then re-use.

2. After connecting, the Bluetooth headset will have a beeping sound, this situation, there are two possibilities, one is not enough power, the second is the phone signal is not good, the connection is not stable.

3. After connecting the bluetooth headset to answer the call no sound, this is you have to check the phone settings, may be the phone's volume off, in view of the bluetooth headset side button volume key adjusted to the maximum. In this way, the problem is solved. Bluetooth headset processing

4. There is also a situation, Bluetooth headset can receive calls, knowledge can not listen to the song, here refers to the ability to have two cases, one is the cell phone audio output (play songs) did not open, two, your Bluetooth headset is a monaural, that is, mono, does not support listening to songs. Bluetooth headset processing

The above situation is only summarized in the customer feedback. Any other situation also hope to discuss together. Thank you!

I. Cell phone issues
When a cell phone is used for too long, there is a possibility that some of the internal call components may deteriorate or malfunction, which can lead to an echo during a call. However, this problem can also occur if the new cell phone is of poor quality.
Solution: It is recommended to send your phone to a cell phone repair point or a cell phone store to have it serviced.

II. Cell phone setup issues
? The phone is set up to record calls, and it's possible to get an echo in this case as well.
Solution: Turn off call recording and there will be no echo. Steps: Settings - Call Settings - Extended Settings - Whether to record incoming calls - Cancel.
III. Signal issues

During a call, there may be signal interference that affects the quality of the headset, resulting in echo problems. In addition, the sound reflection phenomenon may occur in the building, weather and other factors interfere with the cell phone or base station, etc., will produce echo.
Solution: If you encounter this situation, then please hang up or choose a place where the building is not densely populated to make a phone call and so on.

IV. Bluetooth headset issues
The main thing is actually the Bluetooth headset itself, especially the headset cavity structure is not reasonably designed. Learned physics will know, the sound in the process of propagation, if encountered obstacles, it is inevitable to produce echo, structural design is unreasonable, will lead to echo is too large, so that people can obviously feel out, if the microphone of the bluetooth headset with the microphone distance is close, it is easier to produce echo. If you disconnect the Bluetooth headset can be eliminated echo, connect the Bluetooth headset has echo, then this is the problem of the headset itself.
