When buying Bluetooth headsets, many people still pay close attention to the sound quality of the headsets. After all, the headsets are used to talk or listen to music. What are the factors that affect the sound quality of Bluetooth headsets?

1、 Bluetooth version

Bluetooth version is a very important aspect that affects the sound quality of Bluetooth headsets. The higher the Bluetooth version is, the faster and more stable the signal transmission will be. Consumers will encounter fewer phenomena such as signal disconnection and sound jamming in the process of talking and listening to music. At present, Bluetooth 4.1 is widely used in Bluetooth headsets in the market, and Bluetooth 4.2 and 5.0 are used in some medium and high-end products.

2、 Bluetooth chip

The effect of headphone signal transmission is mainly determined by the headphone chip. In addition, whether the chip is equipped with DSP digital noise reduction technology, CVC echo processing technology, and whether it supports apt-X, AAC, LDAC and other technologies are also factors that affect the headphone sound quality. In addition, there are still great differences in the performance of chips of different brands. At present, the performance of CSR's Bluetooth chip is better than that of loda, chuangjie and other companies' products in terms of sound quality. Consumers can try to choose the Bluetooth headset products using this chip when purchasing.

3、 Earphone cavity

Whether the acoustic cavity of earphones is scientific is also an important aspect to determine the sound quality of earphones. However, due to the high research and development cost and the difficulty in realizing innovative discoveries and inventions, few manufacturers have made professional research on this area. Therefore, consumers can not pay too much attention to this aspect of earphones when purchasing.

4、 Earphone horn

The sound quality of earphones is largely determined by the horn, while the sound quality effect of the horn is determined by the magnet, vibrating film and voice coil line in the horn. From the material of voice coil line, the medium and low frequencies of copper wire are better, and the sound quality and life of the sound generating unit are also better. From the type of magnet in the horn, the performance of NdFeB magnet is much better than that of iron oxide magnet. Therefore, consumers try to choose earphone products with the above materials for speakers when purchasing.

The above factors mainly affect the sound quality of Bluetooth headsets. However, many manufacturers in the Bluetooth headsets market carry out false publicity, using fake components as brand components to tempt consumers to buy and obtain higher profits at the same time. Therefore, before buying, consumers had better go to physical stores to listen more to avoid being cheated.
