Usually wired headphones cause great inconvenience to the user due to the wire dropping from the headphone placed on the ear or from the socket of the smartphone, or because of the noise and noise when using it.
The user can avoid all these problems by using the wireless headphones available in the electronics market for a long time, which rely on bluetooth technology instead of wires.
"Our research indicates that the market is moving forward towards wireless headphones," says Felix Fleischmann of the German Fraunhofer Institute for Integrated Circuits. The term "True Wireless" always refers to headphones that fit like earplugs.
Small headphones offer many advanced functions, not just ultra-high-quality audio playback, as luxury models now include microphones, active noise canceling processors and blocking annoying noises while riding in trains, at airports, or walking on busy streets and roads.
Battery operating time
There are some things that the user must consider when purchasing wireless headphones, including battery life, sound quality, and the stability of the headset in the ear, in addition to other technical factors.
Hartmut Giselmann, from the German magazine "Computer Sheet" (c't), points out that the model that fits someone does not necessarily fit with the rest of the people, so it is not possible to rely on comparison tests, but everyone should try a headset from Where comfort and stability in the ear.

Stability of the speaker
In all cases, the user must check whether the headphone rests firmly in his ear, and Felix Fleischmann confirmed that the stability of the headset in the ear very influences the sound quality.
Also crucial is the absence of sound leakage, as the plugs should completely seal the ear canal, otherwise low frequencies will deteriorate and the headphone will quickly sound noisy.
The tests showed that there are significant differences in sound quality between the different models, as the model usually emphasizes deep or sharp tones.
Hartmut Giselmann added, "The focus on deep notes is nowadays fashionable, but when playing the music, that overshadows the details."
The battery life is another important factor when purchasing wireless headphones, and the headphones battery is charged either by USB cable or by the built-in battery in the transport box included with the wireless headset.
Noise canceling function
The user should bear in mind that wireless headphones with noise cancellation function come at a much higher cost than the usual wireless headphones, and German expert Hartmut Giselmann advises travelers who are very mobile to buy wireless headphones with noise canceling function.
However, technologies may emit slight noise, creating a strong sense of isolation from the surrounding world, and causing some people to feel uncomfortable.
Hartmut Giselmann believes that the great slow transfer of sound is still a general problem in headphones equipped with Bluetooth technology, and the response time often exceeds 200 milliseconds, and therefore the wireless headphones are not suitable for music production, and they may affect the audio and video synchronization when Watch the video clips.
