• Sensitivity. It directly depends on the size of the magnetic core built into the structure, and is responsible for the sound volume. Headphones can have a sensitivity of 20 to 130 dB. The higher the sensitivity level, the louder the accessory will be.
• Resistance. Headphones are produced in high and low impedance, in the former, the resistance can be up to 100 ohms, and in the latter, up to 32 ohms. The lower the resistance level, the higher the volume of the device, but the higher it is, the more economical the use of the battery will be (in wireless models).
• KGI. This parameter indicates the clarity and purity of the sound, it is measured as a percentage. For high-quality headphones, the ratio should not exceed 0.5%.
• Power... Its allowable range is from 1 to 5000 mW. To listen to music in high quality, it is not necessary to buy heavy-duty headphones, a few milliwatts are enough. Models with high power provide excellent sound, but under such a load, the battery of the gadget is quickly discharged.
• Availability of customization for the user... Thanks to the presence of such software, headsets acquire additional functions. So, for example, you can create a personal "auditory fingerprint", taking into account the individual characteristics of the user's hearing.

It is also considered important purpose of the device... If you plan to buy headphones for a TV, then you need to choose models with a frequency of 20 to 20,000 Hz, they can be either open or closed. For computer isodynamic headphones with a low frequency are well suited, it is desirable that their design provides for the presence of a microphone. For pocket MP3 players and smartphones you need to choose an accessory with a comfortable fit, medium power. As for professional work with sound, orthodynamic headphones, in the design of which there are 2 magnets and a membrane, are perfect for this.
