Many of us faced with the question of how to choose headphones. But the final decision, and, most importantly, carry the right choice to have the relevant knowledge. To get started, good to decide what you're looking for headphones, and on how much you're willing to spend. Choosing cheap headphones, you must be prepared for a variety of unpleasant surprises such as background noise and annoying hiss hearing, and may even crack. Moreover, it is likely that if the wrong choice of headphones would rub his ears, or simply drop out of them. All this can make the listening even the most beloved songs of the present penal servitude. Choosing headphones: overhead or liners Choosing headphones: overhead or vkladyshiTakzhe should be good to think about what you buy headphones. For a flash player or mobile phone, for example, buy a stupid huge headphones, a few times more of the device. Therefore, for such purposes the most suitable headphone-liners that are inserted in the ears. They have small sizes, so no problem you can always carry with them. And when listening to music, headphones, a small weight is not something that does not cause any discomfort, but sometimes simply forget about them. But no headphone-liners are not able to give a quality that provide overhead headphones. It was in these cases, for example, if you want to buy headphones with good sound for the stereo, the best option would be just such overhead headphones. There are two types: closed and open. The first difference between the maximum strength and prileganiem to the ears, thus avoiding almost all outside sounds. This is an important point, especially if your music is more than a hobby. Since the closed headphones will be issued only to hear the sound of headphones, then nothing will distract you from listening. Second (open) the type of headphone is that still misses the small amount of noise from outside. This makes it sound more realistic than in enclosed headphones. But at the same time, the sound emanating from the headphones, can hinder or even irritatingly effect on others. Connecting headphones Wireless headsets provide freedom of action, but the sound quality of nizheNaushniki also vary according to the principle of signal transmission - wireline and wireless. To the advantage of headphones, in which the sound comes from the wire are the high quality of sound, the less the same - the movements and the constraint of wires, which limits your movement of its territory in length. Wireless headphones allow you to move freely, to give complete freedom of action. But at the same time, the sound quality is very different from the qualities that give wired headphones, and for the worse. In addition to all this, the cost of wireless headphones are much higher than the value of analogies, but with the wires. Sending a signal to wireless headphones made by infrared or radio signal. What's the difference? Connect headphones via an infrared signal gives better sound quality than radionaushniki. But at the same time, the headphones work at ranges up to 8 meters from the transmitter. And, if on the road between the headphones and the signal source has no obstacles (ie, sitting in another room listening to music is still not released). Area action radionaushnikov more (up to 100m), but the reception is not always clear, may be «holes». But if you did decide to buy just a wireless headset, one should pay attention to their food - battery should suffice for a long time to not have to charge every day. The most convenient are the headphones, which are charged directly to the transmitter. Headphone Connectors The set comes with a universal headphone adapter for mmOtnositelno 6.3 connectors, it is the case simply. There are two basic types of connectors for connection: 6,3 mm / 3,5 mm. Most of the headphones and the staff working with 3.5 mm connectors. But the first connector can not be circumvented by the party so I recommend buying generic headphones that support two types of connectors. In such a complete set of headphones in a coupler to connect the connector 6.3 mm. Convenience and comfort of headphones Convenience is often the deciding factor when choosing naushnikovNavernoe, convenience is often the deciding factor when choosing headphones. Because the headphones that fall out of the ears - this is not the headphones. Therefore, when buying the headphones in the shop is their first example, check closely, if they do not fall, and whether to stay firmly in your ears. If you're hard to find headphones that would not rub your ears and they are well kept, it is worth to think about buying overhead headphones. If you're a big overhead headphones, here too there are some nuances. First, it is weight, even if in the hands of those they do not seem to be heavy, after several hours of listening to the headphones may be very weary of your head. Secondly, this type of headphones often damages hair, so I recommend using a model with a ribbon ear, located behind the neck. Separately identify popular today headphone with original design, a form which allows them cling to the neck, the listener can not worry about the wild hair, putting on the back rim. I also want to say that the volume control or a decent length of wire can greatly facilitate your life. These were the questions regarding ease of headphones. To get from buying a good quality sound, you must look closely to the characteristics of the headphones. Frequency Response This is the first thing to pay attention to when selecting headsets, because of their frequency directly affects the quality of sound. Therefore it is preferred headphones, frequency characteristics of which are within the limits of 20-20000 Hz. This will allow you to enjoy this sound without cutting low or high frequencies. In some of the characteristics of the headphones can be seen the upper limit of frequency 20000 Hz is much greater. But this should not involve you in any way, everything sounds better frequency not audible to our ears. Also pay attention to the diameter of the membrane. That's headphone-liners significantly inferior to those placed on the head. As the first diameter of less than 12 mm, it is a significant negative impact on sound quality. In the past, this can reach a diameter of 30-35 mm, which allows you to increase the bass and make itself a much cleaner sound and expressive. Sensitivity This is a crucial characteristic in the selection of headphones, because it directly affects the loudness of sound. The most relevant for inserts, as well as headphones, put on his head, already provide a good volume. When purchasing headphones recommend buying the unit with a sensitivity of at least 90-110 dB. This will ensure a good volume, even in a noisy street. It is also worth noting that, when used with different devices may have different headphones sound. For example, headphones, which seem to be well played on the player, when you connect to a stereo system, you can disappoint. Resistance Good to know that such a resistance and that it affects. Output resistance of the device must comply with the resistance of the headphones. If on the contrary, they will play quieter its capabilities. Most machines are designed for 16 ohms, the truth, there are at 32 ohms, but this is rare. Headphones have high-class resistance to 200 ohms and above. The larger this value, the quieter, high quality headphones will sound with equal sensitivity. Headphones with a high resistance to spend more energy, so be aware - when used with a player if you have enough food for less time. Also not to use headphones with a small resistance in a pair of powerful stereo - such «ears» just do not hold too strong a signal.
