At present, the Bluetooth technology has been updated to 4.0. The Bluetooth 4.0 version has the characteristics of increasing the transmission distance to 100 meters, only 3 seconds low delay, and higher transmission speed. However, the use distance of the previous version of Bluetooth 4.0 is mostly within 10 meters. There will be intermittent sound when it is about 7 meters down, but at present, we are targeting consumers of Bluetooth headsets in the market. Most of the Bluetooth headsets sold on the market are Bluetooth 3.0 and 2.0 products. pay attention. The sound quality and standby time of Bluetooth headsets are also very important. The sound quality is not limited to music playback, but can also affect the quality of calls. Therefore, users who are demanding on sound quality must choose a Bluetooth headset with a higher transmission speed that supports the latest Bluetooth 4.0 version. Headphones, in addition, there is an active noise reduction function that also improves the sound quality. Bluetooth headsets with active noise reduction functions can also obtain clearer call quality in noisy outdoor environments.
1. Check compatibility. Although many bluetooth headsets indicate in the description that all mobile phones with bluetooth function are universal, some older products still have some problems such as the inability to use some function keys, but this kind of problem often occurs in older models of bluetooth headsets , but it does not rule out that some bluetooth headsets (especially small brands or no brands) will have unexpected problems, so it is recommended to check the compatibility between your mobile phone and the target bluetooth headset on the Internet before buying a bluetooth headset. Of course, it is the safest The best thing is to try it out when you buy it.
2. Pick the shape. Appearance is also very important, just like choosing other products, the first sight is very important, the product you don’t like will always become a thorn in your heart when you buy it; secondly, whether it is comfortable to wear and whether it fits your face shape is also an important factor. Important question, it is better to try it on before choosing a Bluetooth headset.
3. Select the Bluetooth version to see the transmission distance. At present, the Bluetooth technology has been updated to 4.0. The Bluetooth 4.0 version has the characteristics of increasing the transmission distance to 100 meters, only 3 seconds low delay, and higher transmission speed.

As for power consumption, the latest Bluetooth 4.0 has lower power consumption in terms of Bluetooth technology. The power consumption also has a strong guarantee for the standby time, and for the earlier version of the Bluetooth headset, the actual use time of the battery of the Bluetooth headset also requires everyone to pay special attention.
6. Select the chip. In fact, the word chip is too professional. I believe that 99% of consumers will not understand the model of the chip, so I will mention the chip at the end here. At present, the Bluetooth headsets on the market are mainly composed of two major companies, one is the British CSR company, and the other is the American Zeevo company (now acquired by the American Broadcom company), and about 80% of the products on the market use the industry The chip of the famous csr company in China, the advantage of the csr chip is its small size and strong ability to suppress noise.
