Stereo headphones: features, model overview, selection criteria

Stereo headphones are very popular. These gadgets have a number of significant advantages over mono systems. The range of offered models is so wide that it is rather difficult to make a choice without knowing all the subtleties and nuances.

In our informative review, we'll try to figure out how to choose the right reliable and high-quality stereo headphones so that they allow you to enjoy perfect sound reproduction.

First, let's understand what the definition of "stereo sound" means. Imagine that you have one conventional microphone, on which you can record only one audio file. You can place it in front of an entire orchestra right in the middle of the room and record. In this case, you will get mono sound: if you reproduce the audio sequence in the headphones, it turns out that in the right ear you will hear the same melody as in the left. When listening, it will give the impression that the sound is as if in the center somewhere between these headphones.

Now imagine that you have two microphones at your disposal, one to the right of the orchestra, and the other to the left. You recorded again and it turned out that each of the microphones made a different version of what the musicians were playing. At first glance, it may seem that these records are identical, but this is far from the case. If you reproduce the audio sequence in the headphones, it turns out that in the right one the signal coming from the right microphone will sound. And in the left ear is recording, respectively, from the left.

The stereo system provides more powerful, spacious and clear sound, in which the listener can distinguish dozens and hundreds of shades. This means that at the time of listening to melodies or other audio recordings, as well as watching movies, each user will be able to perceive all the most subtle sound nuances that were inaccessible to them in the years when only single-channel audio systems were on sale.

The parameters of stereo headphones include several important characteristics that directly affect the quality of sound reproduction.

The stereo system covers the entire range available to the ear. As you know, the hearing organ of a healthy person can perceive acoustic vibrations in the frequency range from 20 to 20,000 Hz. The vast majority of stereo headphones are marked with just such indicators.

Stereo headphones provide optimum sensitivity. This parameter is responsible for the volume of audio content and energy efficiency. Most modern models have characteristics in the 90-105 dB corridor.

Optimal impedance. The strength of sound reproduction directly depends on the parameters of resistance. The maximum number of amateur models, as well as gadgets that are used for players and smartphones, have parameters from 16 to 50 ohms. Professional devices are rated for over 100 ohms.

Thus, we can safely say that stereo headphones meet all the requirements for high sound quality and provide a clear, natural and comfortable audio experience. This is the main advantage over traditional models. Stereo sound provides a surround sound experience that immerses listeners and feels right at the heart of the sound.

Stereo headphones are divided into several categories, they can differ in design, principle of use and convenience. Let's consider the main options.

Such devices consist of a pair of speakers, as well as an arc. They are worn over the head, and the speakers are attached to the ears. Usually, they do not adhere to the auricle so tightly as to fully isolate all extraneous sounds in the environment.

These are professional headphones, although they can be used in a home environment. They are also worn over the head, while the ear pads completely cover the auricles, thereby preventing the penetration of extraneous noise. The only drawback of the gadget is its massiveness, so it takes time to get used to wearing it.

Both types of headphones can be open or closed, and this also largely ensures sound clarity.

In this case, small holes are provided on the outside, through which sound partially leaks. Thanks to this structure, the most natural sound is provided. At the same time, they can also pass some third-party sounds, therefore they can be used either indoors or on a deserted street so that external silence is provided.

They are bowls, the outer part of which does not have any holes. Thus, the devices allow you to keep the sound inside and completely prevent the penetration of background noise from the outside. However, due to the vacuum created in the ear, the sound quality may be distorted.

Gadgets that are literally inserted into the auricle are very popular among young people. However, they do not adhere very tightly to it, so a significant part of the low frequencies is lost at the time of their production. In addition, these earbuds do not have sound insulation, so they can let in noises from the outside.

These headphones are called "in-ear" headphones. The silicone ear cushions in them are neatly placed in the ear canal and fit quite tightly to it, thereby forming a vacuum. Such headphones reliably isolate the listener from the penetration of any extraneous noise. They reproduce high and low frequencies well. However, listening to music too often and at the same time loudly can adversely affect the condition of the hearing organs. However, with reasonable dosage of use, in-ear devices can be considered the most suitable for listening to recordings.

There are a number of factors you should pay special attention to when choosing stereo headphones.

For domestic amateur use, earbuds and vacuum gadgets are considered the most comfortable. Overhead models are heavier and some users report headaches due to the firm attachment.... Some women do not like overhead models due to the fact that they spoil the styling.In addition, such devices cannot be hidden in a pocket, and it is not always possible to place them in a handbag.

Stereo headphones can be wireless or wired. The former usually establish a connection via Bluetooth. This solution is quite convenient, but it also has its drawbacks. Such gadgets require frequent recharging, and they can only connect with those devices that have a built-in Bluetooth option.

It is rather difficult to say how long these or those headphones will work, since much here depends on the features of the model, the configurations used and, of course, on the accuracy of the user and the intensity of use. As a rule, reliable manufacturers give guarantees for their products within six months, less often for a year. Subject to strict observance of all the rules of use, high quality stereo headphones can serve for several years.

Stereo headphones are often purchased with a TV set to watch movies. In this case, experts advise to select overhead models with high-quality sound insulation. Please note that in this case it is worth picking up products with a 3-4 meter long cable.

Vacuum headphones are usually purchased for smartphones and tablets. Although if there is such a desire, then invoices can also be purchased. However, it will not be very convenient to take them with you on a long journey.
