If you doubt this and want to know about the technical specifications, features of the best models from experts from the Land of the Rising Sun, then you need to carefully read our article.

About the manufacturer

Today, even first-graders know the name of the Japanese corporation Sony, it was formed in the difficult post-war years for the country and at the beginning of its activity had a different name Totsuko, but at the beginning of the 50s of the last century the ancestors of the company decided to change the word unpronounceable for Europeans - this is how the famous future appeared worldwide brand SONY.

The subsequent period is considered the golden period for Sony: all products entering the world market are sold out instantly, because the quality and reliability of the equipment is head and shoulders above all competitors. For example, during 1990 the company successfully sells over 500 different innovative products, Sony leadership becomes unconditional - devices with the inscription made in Japan and the corporate logo of the corporation are sold in all countries of the world.

At the beginning of the new millennium, competitors began to overtake the Japanese company, because consumers did not want to pay more for a well-known brand - Samsung products appeared that were much cheaper and better in functionality. The corporation gradually lost its leadership, but did not give up and began to engage in other projects, for example, the famous Sony-Ericsson phones appeared after the merger of the Japanese company with the Swedish company Ericsson at the beginning of this century.

Specifications

For each model of devices for listening to music, the main technical parameters are indicated in the passport:

1. Electrical resistance (impedance), Ohm.
2. Ratio of noise exposure to maximum power (sensitivity), dB / mW.
3. Frequency response.
4. Range of reproduced frequencies, Hz.
5. Maximum power of the product, mW.
6. Harmonic coefficient (THD).

According to these characteristics, the selection of the best option is carried out, and how to do it better, we will explain in detail in another section.

Advantages and disadvantages

Each technical product has its own advantages, as well as some disadvantages, and headphones from the famous company marked Extra Bass, which means extra - the highest degree of quality, Bass - low frequencies or just bass, is no exception.

Pros:

1. Wired and wireless connection.
2. Battery capacity allows up to 20 hours of battery life.
3. Surround sound quality with any connection.
4. High build quality, as well as all materials used.
5. Any model with a microphone can be used as headphones or a headset.

Minuses:

• the bulkiness of the structure and the large mass, although expressed in grams;
• limited equipment without case and adapter.

The products of Japanese specialists are famous for their reliability and innovative developments, but it is also quite easy to find some flaws in perfect products.

Principles of Successful Choice

Before visiting a specialized store selling various acoustic systems, each potential buyer should find out which model of headphones he is going to purchase, otherwise you will be stuck in a retail outlet for at least several hours, if not before closing. The offered assortment is so extensive that in one visit you will not be able to inspect all models.

Device type

By design, all headphones are divided into the following types:

1. Plug-in or earbuds - they are inserted into the auricle.
2. The intra-channel variant differs from the first variant in that the long nose of the device penetrates the ear canal.
3. Overhead products - are applied tightly to the ear, but do not cover it. The pressing force on some models is regulated by a special mechanism.
4. Full-size option - ear pads cover the auricle, creating a kind of space for a better perception of sound vibrations; they are closed and open.
5. Monitor devices are already for the professional work of musicians and sound engineers.
   The design implies the use of the product: for smartphones, PCs or listening to music from other sources indoors or outdoors.

Emitter

When buying, many consumers do not pay attention to this criterion, but in vain, because emitters come in different designs:

1. Dynamic, standard version with a membrane of different diameters.
2. Electrostatic devices of the Hi-End class have a rather high cost.
3. Isodynamic and orthodynamic products with a very complex emitter design.
4. Reinforcing - they can be found in expensive models of in-ear headphones.

You can familiarize yourself with all types of designs in detail on the Internet or on manufacturers' websites.

Signal transmission

There are two types of connection:

1. Wired - by connecting headphones to the sound source using a different cable length with a 3.5 mm jack.
2. Wireless option - Bluetooth of various modifications is used, as well as a Wi-Fi system, characterized by a large range and the ability to listen to music tracks directly from the Internet.
   For the second option, battery life is very important, which for expensive models comes to 30 hours of continuous operation.

Each model has different functions: an adjustable headband, interchangeable ear pads, the ability to rotate the speakers around its axis by 90 degrees and much more, so when choosing carefully read the instructions for use, especially the smallest text: sometimes it contains very valuable information.
