What are the types of Bluetooth headsets?

Someone once asked the editor of the future design, what is the difference between wireless earphones and bluetooth earphones? Why are some earphones called Bluetooth earphones, some are called wireless earphones, and some are even occupied, called wireless bluetooth earphones?

In fact, there is an inclusive relationship between Bluetooth headsets and wireless headsets, and there is no direct affiliation. However, it should be noted that Bluetooth headsets can be wireless headsets, while wireless headsets are not necessarily Bluetooth headsets. The concept of wireless headsets is more extended than Bluetooth. Headphones are wider.

Wikipedia describes it this way:

A Bluetooth headset is a small device based on Bluetooth technology. It is only necessary to hide this lightweight device beside the headset without directly using communication devices (mobile phones, computers, etc.) to achieve free calls.

Wireless earphones are the middle wire replaced by radio waves. They are connected from the audio outlet of the computer to the transmitting end, and then sent by the transmitting end to the earphones of the receiving end through radio waves. The receiving end is equivalent to a radio.

Wireless bluetooth earphones include bluetooth earphones and infrared earphones.

There are three known types of wireless headsets: one is Bluetooth headset, the other is infrared headset, and the third is 2.4G.

Although Bluetooth headsets and wireless headsets are included, there are still differences between the two. Bluetooth headset is a low-cost and high-capacity short-distance wireless communication specification. The transmission distance usually depends on the technical support provided by Bluetooth. The basic communication distance is about 10 meters, the transmission rate is about 721kbps, and it works in the 2.4GHz frequency band. Support One-to-many data transmission and voice communication. For wireless earphones, the middle line is replaced by radio waves. It is connected from the audio outlet of the computer to the transmitting end, and then the transmitting end sends it to the earphone of the receiving end through radio waves. The receiving end is equivalent to a radio, and the working distance is within 7 meters. , Poor diffraction, if there are obvious obstacles (for example: people, large pets) between the infrared wireless headset and the transmitter, the answering of the infrared headset may be interrupted. The working distance of wireless Bluetooth headset can be about 100 meters, the working space is more free, and it has good music playback effect, and the confidentiality of communication is relatively strong, not only good sound quality, but also energy saving and lower cost.

After this combing, the editor of the future design believes that everyone should be able to distinguish the difference between wireless earphones, wireless bluetooth earphones and bluetooth earphones. You can refer to this article when purchasing to choose the style of earphones you want and need. .
