The emergence of the new traffic regulations let our driver friend a little helpless, driving time is not allowed to make a phone call, catch the deduction points but also deduction money. A lot of chauffeur friends wonder if there is any other way to avoid it. The advent of Bluetooth headsets has solved this problem for our chauffeur friends and stopped worrying about driving on the phone. In fact, many friends are equipped with Bluetooth headset, it can be said that Bluetooth headset has become a fashion. But in the face of so many Bluetooth headsets on the market, what kind of headset is suitable for you? Today, I would like to introduce you to the Bluetooth headset selection skills and in the purchase of some of the small details to pay attention to.
The first is to look at the compatibility of Bluetooth headsets.
In fact, no matter what kind of communication equipment compatibility is particularly important, in order to better play its effect, Bluetooth headset is no exception. Some Bluetooth headsets are incompatible with mobile phones, resulting in poor call quality, directly affecting the effect of our calls, lost the original meaning of Bluetooth headsets. Incompatibility in nature is due to different specifications. Bluetooth headsets now generally come in two specifications-HandfreeProfile (HFP) and HeadsetPro-file (HSP). HFP stands for hands-free function HSP stands for headset function. So when we buy, we must find out what kind of specifications our mobile phones support, and only when we use them can we make the best use of them. If the buyer does not understand, be sure to ask the seller, do not buy back can not be used.
And then there's the viewing chip.
The brand Bluetooth headset chip supplier has so far been offered by two major companies Broadcom in the United States and CSR in the United Kingdom. In general, Broadcom in the United States has a relatively large share of the market, accounting for about 80%. It is important to note that if it is not for the chips provided by these two companies, we should not buy them. The quality of chips is also closely related to the quality of calls.
The third is the transmission distance.
Bluetooth headset transmission distance is also a problem for friends. From the point of view of data analysis, the transmission distance of Bluetooth headset mainly depends on the advanced level of Bluetooth headset technology. There are two things to say here: the standard transmission distance of PowerClass2 is 10 meters, and the upgraded PowerClass1 increases the transmission distance to 100 meters, but judging from the Bluetooth headset currently available on the market, PowerClass2 is dominant. But now PowerClass2 is all we need. When we make a phone call, the distance between the phone and the Bluetooth headset is usually not more than 10 meters away.The optimal transmission distance is theoretically between 2-3 meters, beyond which there will be intermittent discontinuities, but it also depends on the quality of the headphones.
The fourth is to look at the version.
We often see numbers like Bluetooth 1.1, 1.2, 2.0 when we buy Bluetooth headsets. On the one hand, it represents the version of the Bluetooth headset, on the other hand, it represents the anti-interference capability of the Bluetooth headset. The current mainstream version is 1.2, but 1.1 is the most common, and 2.0 has not been around for a while. Variations in versions can also affect the signal quality of Bluetooth headsets. The emergence of new things will more or less mask the old things, the new version of Bluetooth headset is more anti-jamming ability. The compatibility of the new version is also good, but the price may be more expensive, when we buy according to their own needs to choose to buy.
Number five is comfort.
Bluetooth headsets can also be a headache for driving friends. Because the belt is usually a very long time do not take off, a long time wearing will make the eardrum have a kind of uncomfortable feeling. So when you choose, you must wear it first and feel comfortable to wear it.
The sixth is appearance.
Out of the features we must take into account, Bluetooth headset appearance is also the place we should pay attention to. Because each person's face shape is different, requires us to choose the Bluetooth headset shape also not to be the same. So you have to take that into account when you make a choice.
