Choosing headphones

Everyone who buys cheap headphones is often forced to experience disappointment in their purchase.

Sometimes such headphones come with the supplied player or phone.

Often, after some time, cracking, extraneous noise and other unpleasant effects appear in the headphones. Quite often, it becomes obvious that the headphones rub their ears, they are uncomfortable and not firmly held on their heads and have a number of other negative qualities.

Professionals attribute headphones inserted into ears (in-ear) to stereo phones of the most entry-level level. The reason is simple: with their apparent convenience and cheapness, there is a clear drawback – poor sound quality, in particular, low frequency weakness. Manufacturers unsuccessfully try to fix this due to various technical tricks, but it is impossible to extend a wide frequency range from a 9 mm membrane while observing the small size of the headphones.

How to choose headphones that would satisfy your particular request? To successfully complete this task, it is necessary to select headphones for the following characteristics:

Frequency response

This feature greatly affects the sound quality of the headphones. If you notice a hiss and a metallic tint of sound at very low or very high frequencies – this is a consequence of the imperfection of the headphones in the frequency range.

As a rule, the low limit of the frequency response plays a particularly important role. If you are especially anxious about sound quality, then it is better to choose headphones with enhanced sound quality – headphones with a large diameter membrane.

Despite everything, practically none of the in-ear headphones with a membrane size of 9-12 mm are able to compete in the purity of sound with on-ear headphones or monitors that have a membrane diameter of 30 mm and above, which allows them to significantly expand the frequency range and improve sound quality .

The average value of the frequency response that a person can perceive: 18-20000 Hz. If the frequency range of the offered headphones is narrower, you should think three times before buying such headphones.

Sensitivity

Sensitivity affects the sound volume in the headphones. It is possible for monitor headphones that always provide good volume, and this is not relevant, however, when choosing in-ear or on-ear headphones “for the street”, you should pay close attention to this.

It is necessary that the headphones provide a sensitivity of at least 100 dB, otherwise the sound may be too quiet when using headphones with a player or similar devices.

Also, try to pay attention to what magnetic cores are used in headphones. It is not recommended to take in-ear headphones with a small diameter membrane that have a low-power magnet. It is best to opt for headphones with neodymium magnetic cores.

Neodymium magnet – as a rule, it is made in the form of a magnetic core made of an alloy (in dynamics, a headset) containing a rare-earth neodymium metal. Improves the sound quality of high and low frequencies.
Ease of design of the headphones is achieved.

Type of connection

If you decide that you are taking headphones for a large stereo system, then the question may arise before you: stop on a wired or wireless model? Consider their advantages and disadvantages.

For headphones with a wire, the drawback is obvious – it is the very presence of a wire that restricts movement.

In the case, even if you take a long wire, you will not be able to sit on a bed in the garden, dance or just walk around the apartment, enjoying the music without confusing it.

However, in this case, you are always guaranteed the maximum sound purity that similar headphones are capable of delivering.

With wireless headphones, everything is different. There is complete freedom of movement – some models provide such a good sound transmission that you can listen to music freely moving throughout the apartment, and often further.
However, special attention should be paid to the transmission quality, channel frequency and automatic tuning.

Despite the fact that modern wireless headphones, both radio and infrared, can easily provide sound transmission with minimal distortion, it is still worth paying closer attention to the above characteristics.

Another disadvantage of this type of headphone is the battery. Obviously, the battery life of the headphones should be long enough to provide hours of listening. Although, the most convenient in this case will be headphones with batteries, with the possibility of recharging.

Acoustic design

According to the acoustic design, the headphones are divided into open and closed.

Closed headphones do not let in any external sounds, while open ones allow you to hear environmental sounds.

Despite the fact that the acoustic design is a matter of taste, it is worth warning that open headphones give a clearer picture, while in closed ones there is a slight resonance.
