Simply put, Bluetooth is a wireless transmission protocol,
First of all, you have to select the Bluetooth on your mobile phone to be turned on,
Then, select the search device. At this time, press and hold the call button on the headset for about 10 seconds. A flashing light flashes, indicating that it is turned on.
If under normal circumstances, the phone will search for the device and select it as authorization, it won’t be so complicated next time you use it.
However, many Bluetooth devices are not easy to pair successfully when they recognize each other. At this time, you need to try a few more times.
When purchasing Bluetooth headsets, because there are many manufacturers of mobile phones and headsets, the most troublesome issue for consumers is the compatibility of mobile phones and headsets.
The manufacturer pointed out that in terms of specifications, Bluetooth headsets have two major factions, Handfree Profile (HFP) and Headset Pro-file (HSP), which determine the compatibility of the headset and the mobile phone. The former means hands-free function, and the latter means earphone function. Consumers must first research which specifications their mobile phone supports, and then find a suitable Bluetooth headset to pair with.
Among them, the Bluetooth headset of the HFP format supports more complete functions of the mobile phone. Consumers can operate the hands-free options such as redial, call retention, and call rejection on the headset at the same time. Take the Bluetooth headsets introduced by several major manufacturers such as Nokia, Motorola, and Sony Ericsson as examples. Almost all of them support the HFP format, and some models support both HFP and HSP. Consumers should pay special attention when purchasing.
In addition, when consumers purchase Bluetooth products, they often see numbers such as Bluetooth 1.1, 1.2, 2.0, etc. The numbers represent different specifications and standards. At present, 1.1 is the most common, 1.2 is the new mainstream, and 2.0 is just recently launched. The different versions of Bluetooth are related to the quality of the received signal. The new version emphasizes the ability to overcome noise interference, and the new version can also be backward compatible. For example, the new Bluetooth 1.2 can be backward compatible with the 1.1 standard. Consumers should consider the price when purchasing. And demand.
Another important decision point of the Bluetooth headset is the transmission distance, which has nothing to do with the Bluetooth version, but depends on the Bluetooth technology Power Class.
Mainstream brand bluetooth headset purchase-8 models introduced
Although Bluetooth as a short-distance wireless connection technology has been around for a while, it has many functions that can be realized. But for most ordinary consumers, the most intuitive embodiment of Bluetooth technology is the Bluetooth headset. From the high price of tens of thousands of yuan at the beginning to the price of only a few hundred yuan now, Bluetooth headsets have long since gotten rid of the image of being superior in the past and have begun to enter the homes of ordinary people. At the same time, the number of mobile phones that support Bluetooth technology on the market is also increasing. Therefore, how to choose a Bluetooth headset that suits you from a variety of brands has become the focus of this topic.
Under normal circumstances, whether a Bluetooth headset is excellent can be measured by call quality, weight, wearing comfort and compatibility, and standby time. We deliberately collected several popular Bluetooth headsets on the market, and dedicated a shopping guide for Bluetooth headsets to the majority of netizens, and hope to be helpful to everyone.
Generally speaking, when purchasing a Bluetooth headset, we must pay attention to the performance of the headset in the following aspects:
conversation quality. Call quality is the most basic performance parameter to measure the quality of a Bluetooth headset. Generally, using a Bluetooth headset with a rod-type design because the microphone is closer to the mouth, the call quality obtained is relatively better than other types of products. This is why the older generation of Sony Ericsson HBH35 is popular.
compatibility. Although Bluetooth products do not have serious compatibility issues, if you buy a headset that can’t always be paired and connected with the mobile phone, it means that this headset has a certain gap in compatibility. In addition, although Nokia’s HDW-3 is good in terms of call quality, it is not equipped with a charger, so there will be some inconvenience if it is not a Nokia mobile phone user.
Wearing comfort. Our ears are relatively delicate. If the ear hook material of the earphone is not good or the design is flawed, it will cause discomfort after wearing it for a longer time. Therefore, you should check carefully before buying and choose a Bluetooth headset that suits your ear shape. In addition, if you are a friend who wears glasses, it is best to choose a Bluetooth headset with hands-free and wired headset.
Standby time. This is the same as the daily use of mobile phones, we hope to have a better standby time to avoid the trouble of frequent charging. Usually Sony Ericsson products and Motorola HS810 have good use and standby time.
weight. This parameter is also a test of the endurance of our ears. In theory, the lighter the headset, the better. However, the weight of Bluetooth headsets is mostly more than 20 grams, and the weight difference between them is not large, so we can buy them according to our own preferences.
