What are the factors that affect the sound quality of Bluetooth headphones?

Many people buy bluetooth headset, or very concerned about the headset sound quality, after all, buy headset is used to talk or listen to music, then what are the factors that affect the sound quality of bluetooth headset? Below, the technicians of the Emini technology to popularize it for everyone, so that consumers can make the right purchase decision when buying headphones.

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.
