The wireless headphone is a device that receives sounds from a source using wave technology. The most suitable model is selected depending on the operating conditions.
Many people believe that the technology of wireless transmission of information is harmful to the human body. But this is an erroneous opinion. Experts, after conducting a lot of research, confidently declare that the wireless audio headset meets all safety requirements.
A distinctive feature of all modern models of wireless headphones is the long-term operation without the need for additional recharging.
In addition, they are equipped with a user-friendly interface. They can be used both for listening to music and for talking on the phone.
Device and principle of operation
The principle of operation of headphones that do not have wires is to receive sound information from the main source due to the presence of special technologies. Today, there are 3 main ways to transfer data from a smartphone to wireless headphones.
The most stable method of communication with a range of more than 10 m. But, unfortunately, using this type of connection in headphones is not very convenient, since the design requires the installation of an additional transmitter that you must carry with you all the time.
This technology is a universal way to transfer data from the main carrier to a paired device. Headphones with Bluetooth connection to any gadget equipped with a Bluetooth module. A distinctive feature of this type of connection is the stability of the work. Not once did users complain about the loss of wireless connectivity. Individual encoding of devices allows you to protect the transmitted data from interceptors from other gadgets.
The infrared method of data transmission is slightly outdated, but still in demand. Products equipped with this technology work on the principle of high-frequency ripple data transmission.
A special receiver is built into the design of headphones with an infrared port, which amplifies the reception of sound signals. Such headset models are very convenient, but not always suitable for connecting to smartphones.
Wi-Fi type connection indicator
Quite often, there is a Wi-Fi type connection indicator on the packaging of headphones for the phone. However, this definition indicates the presence of a Bluetooth module in the headphones. Wi-Fi, by all its criteria, cannot be a means of transmitting sound information from a phone to headphones. Wi-Fi is a wireless way to connect to the Internet. But out of ignorance, many users purchase headphones, on the packaging of which the connection is indicated by the type of Wi-Fi connection. And only after they find out what was the catch.
Modern wireless headphones are divided into several categories.
- Communication type: This includes radio waves, infrared and Bluetooth technology.
- Ergonomic component: It involves the division into devices of in-ear and overhead types.
Even by their name, it becomes clear that remote in-ear models must be pushed into the ears, forming a seal. Accordingly, good sound insulation is created. It is worth noting that hearing aids are considered the forerunners of the in-ear type of headset. The design of such models is very convenient, has a small weight and a pleasant shape. Unfortunately, they are limited in the transmission of the upper-frequency range.
Inexperienced users quite often confuse the design of in-ear headphones with in-ear models and earbuds. But there is quite a big difference between them.
The wireless ear pods are inserted into the auricle and held by the force of elasticity. But in-ear models cannot boast of a snug fit to the ears and fall out quite often.
The design of over-ear headphones can be opened, semi-closed, and fully closed. In open and semi-closed versions, it is not necessary to talk about good sound insulation. Extraneous sounds in the streets will haunt a person. However, premium open and semi-closed models are complemented by a unique noise reduction system that automatically processes outgoing information, removing, and blocking extraneous sounds.
Overhead headphones can also be attributed to overhead models of an audio headset. Their soft comfortable cups completely envelop the ears, thereby providing high-quality sound.
It is a full-size headset that is the best protection against excessive noise. But their size and dimensions are not acceptable to every user.
