Headphones allow you to listen to music from various media devices, a personal computer or smartphone. The comfort of others is not violated. However, wires are a significant drawback. They get confused, get in the way, can fall out of the nest. Therefore, the wired headset was replaced by wireless headphones, which very quickly gained popularity among users. What are they and what are their features?
The entire headset differs in several ways. It can be with an external or built-in battery, with a built-in microphone. It is also divided according to the principle of work.
Infrared
This is the first ever way to wirelessly transmit audio. To implement the work in such headphones, a special sensor is used. The infrared standard is convenient in that it does not require licensing, unlike a radio signal. The main advantages are the low cost of such products and the fact that they are insensitive to external electromagnetic interference. However, such a communication channel has significant drawbacks, and therefore has lost its popularity. The cons include:
- when any obstacle appears, the signal disappears;
- IR signal does not work in direct sunlight;
- small radius - the average working distance is 4-6 m.
REFERENCE! Now a headset of this kind is very difficult to find on sale, since it has practically ceased to be released. It is usually used complete with TVs or car radios.
If you do not plan to leave the sound source, and there are no obstacles in the room, then such headphones will become a good choice, especially since they have a low cost.
Headphones
They became the next stage in the development of wireless audio transmission technology. The frequency range used is from 800 to 2.4 g Hz. It allows you to transmit audio over a fairly large distance. The radio signal is not afraid of walls and other obstacles, which allows you to walk with a headset throughout the house. But, such headphones have disadvantages:
- when sounding, extraneous noise and interference may appear;
- consume a lot of electricity, so the operating time is short.
This type of wireless headphone is very popular. This is a great option for watching movies or gamers. But they will not suit music lovers.
Bluetooth
This type of communication was invented in 1994 in Sweden and quickly gained popularity. It requires little electricity, is not exposed to external electromagnetic waves and is universal. The bluetooth headset can be connected to any device - a TV, computer, smartphone and more. Sound quality depends on the type of Bluetooth protocol. Each of them transmits a signal at a different speed. So, the very first 1.2 transmitted sound at a speed of 721 Kbps. More modern 3.0 has a transfer speed of 24 Mbps.
Wifi
The most advanced wireless option. The distance and radius of the transmission depend on weather conditions, the availability of electronics and reflective surfaces.
Also, these headphones are divided into several types:
- waybills;
- full-sized;
- vacuum;
- monitor
- intra channel.
