• IR headphones. Infrared or IR headphones work on the principle of wireless transmission of the sound signal using infrared LEDs (transmitter) and a special infrared receiver located in the body of the headphones. The signal reception radius of such models is very limited, and for good sound quality, the infrared transmitter must be located exactly opposite the listener.

Wireless headphones are available in a variety of form factors:

• True Wireless (TWS). Perhaps the most actively developing segment, as these models are distinguished by excellent portability: they are equally convenient when traveling, on a walk, as well as when used at home or in the office. If necessary, such headphones can be put in a special charging case and put away in a pocket or bag. Since the small case does not allow the use of very capacious batteries, true wireless headphones will have to be periodically recharged, putting the music "on pause".

• Earbud. In-ear headphones are one of the most common form factors: they provide a good balance between sound quality, comfortable and easy to use, and allows you to hear your surroundings well in most cases.

• In-ear headphones. Compared to conventional "earbuds", they have some advantages: improved noise insulation and more confident bass reproduction. Such models are well suited for use in noisy environments, but sometimes you should be more careful and remove in-ear headphones in situations where it is important to hear the environment - for example, when crossing the road.

• Over-ear. Such headphones can be an excellent option for use at home or in the office, as well as for listening to music on trips or on a walk. Good over-ear headphones can become a stylish accessory that successfully emphasizes the image of their owner.

• Full-size. The main difference of full-size headphones is high sound quality, along with comfort while listening: unlike over-ear headphones, full-size models do not put pressure on the ears, so you can listen to music in them for a long time without any fatigue.

Many models of over-ear and full-size wireless headphones are equipped with a folding mechanism, which allows you to conveniently store them in a backpack or bag. Also it is worth highlighting sports and gaming wireless headphones, designed specifically for these activities.

According to the type of acoustic design, wireless headphones are:

• Closed. The body of such headphones practically does not transmit sounds from the outside. This improves the level of noise insulation, but can adversely affect comfort with prolonged use.

• Open. Such models are optimal when used at home or in the studio, as they skip external sounds and provide increased comfort, and also allow the emitters to move more freely in the body of the headphones, which reduces sound distortion.

• Semi-open. They combine the features of open and closed models: such headphones transmit sound from the outside (and outside), but less extent than open models.

Some models of wireless headphones are also equipped with an active noise-canceling system, which allows you to neutralize external noise by superimposing a certain sound generated by the emitters.

How do I choose wireless headphones?

When choosing wireless headphones, it is worth considering the issue of their ease of use (form factor, ergonomics), technical characteristics, as well as the presence of additional functions (for example, active noise-canceling and a built-in microphone for calls), which can be a tangible advantage in certain situations.
