How to choose headphones? A few practical tips

Since the invention of Alexander Graham Bell in the second half of the nineteenth century, headphones have undergone a large number of changes and have firmly entered into the lives of not only music lovers who do not represent their lives without music, but also all fans listen to the radio on their way to work or "read" a new audiobook, Not disturbing the home. With the advent of almost every home of a personal computer, headphones have become an indispensable attribute in every family. But does everyone know how to choose headphones and which aspects should you pay attention to when buying this accessory?

The first thing to look for when choosing headphones is the frequency range. It should be borne in mind that the principle "the more, the better" in this case does not always work. So how to choose headphones with the "right" frequency range? To begin with, it is important to know that the human ear is capable of perceiving frequencies in the range of 20 Hz to 20 kHz. The beginning of this segment is responsible for "bass", and at the top are high-frequency sounds. For good headphones, it's not the width of the frequency range that is important , but the correct reproduction of frequencies precisely in this range, without blockages, "bubbling" or wheezing at low frequencies and without grinding or hissing at the top and middle frequencies. As a rule, all manufacturers indicate the main technical characteristics of their product, including the amplitude-frequency indicators, on the packaging or in the attached instructions.

The second important characteristic when choosing headphones is resistance. In fact, the more the accessory has this feature, the more powerful the device is needed for such headphones for optimal performance, and much less impact on the sound this source has. Simply put, a low-quality player can be connected headphones with a resistance of 8-16 Ohm, but to fully enjoy the music will not work - this will distract the crack of internal processes, the noise of the amplifier and other extraneous sounds. If you connect large "monitor" headphones with a resistance of 250 Ohm to this player, the sound in them will be very quiet and flat - the headphones will not play, but will "whisper". The optimum resistance range for portable devices is 32-64 ohms. Knowing this will tell you how to choose the headphones for the player "correctly".

Another significant factor that significantly affects the sound is sensitivity. The more this characteristic, the louder the sound. Accordingly, the lower the sensitivity and resistance, the quieter these headphones will play the sound.

Many buyers before buying this accessory think about what to choose - vacuum headphones or "normal". In this issue, it is best to focus on your own feelings during the trial listening and convenience factor. It should also be remembered that even with the sound turned off, the world around in vacuum headphones "ducks" quite strongly, so with such a device, it is desirable to cross the road very carefully and generally be more collected on the street.

And the last part of the question of how to choose headphones is the acoustic design of the upcoming purchase. In this regard, headphones are "open", "closed" and "half-open". In addition to the appearance, acoustic design affects the sound insulation - in the "closed" headphones, the external world will be "drowned out" by music as much as possible, and those around you will not hear what is playing in your headphones even when playing at very high volume. But in the "closed" headphones there is one minus - the sound does not go outside due to the deaf back of the speakers and may be slightly distorted.

One of the most popular headphone manufacturers at the moment are such companies as Koss, Sennheiser, Sony, AKG and Philips, but there are a number of other manufacturers that provide the market for headphones with quality and worthy of attention.
