Bluetooth headset introduction
Bluetooth headsets are popular among consumers because they are not limited by wire. With the diversification of market demand, there are many types of Bluetooth headsets. There are single-ear Bluetooth headsets, dual-in-ear Bluetooth headsets and headset Bluetooth headsets. So, what are the characteristics of different types of Bluetooth headsets?
The single-ear Bluetooth earphone is a product that has just emerged as a Bluetooth headset. It was not shipped to listen to music when it first appeared. Therefore, even if the A2DP Bluetooth stereo protocol is not supported on the mobile device, a single-ear Bluetooth headset can also be used. This type of earphone can only be used in scenes such as calling, hanging up, and adjusting the volume. If you need a pair of Bluetooth headsets during driving, then it is suitable, so it is also called the car Bluetooth headset. Although the sound quality is not good, there is no problem with the call. More importantly, the single-ear Bluetooth headset allows you to hear the surrounding sound while driving, increasing the safety of your driving.
Dual in-ear Bluetooth Earphone
The dual in-ear Bluetooth earphone is the so-called stereo Bluetooth earphones, which must be based on a mobile phone that supports the A2DP Bluetooth stereo protocol. Its usage scenarios and the use of mono-ear headphones have changed dramatically, and it has focused more on the needs of consumers listening to music. For example, Apple's original dual-in-ear Bluetooth headset can be used not only to listen to music, but also to interact well with the front end (summon Siri assistant). The following is a true wireless Bluetooth headset I7 that is very hot in 2018.
Headband-type Bluetooth headsets are more pleasing to the love of music-loving consumers than dual-in-ear headphones, which can be said to be more popular with music enthusiasts. Because the headset not only gets rid of the shackles of the wire, but also performs better in terms of sound quality and sound field. Not only that, but some headphones also have good active noise reduction, which is very popular among business people.
The D422 has a metallic feel and has the lightness of a metal earphone.
