Today, almost everyone has headphones – someone listens to music in them, watches movies, or plays; someone needs them for work or sports. Each type of headphones is suitable for its purpose: to choose the right model, you need to determine what they are for.
9 Steps | How to Choose Headphones
What are the headphones: wired and wireless?
Wired headphones are a classic. They are quite comfortable and give a quality sound. Because they’re on wires, losing them is harder than wireless. Minus such models – the wire is constantly confused, breaks suffers plug. However, there are more wear-resistant headphones – with a flat wire and an L-shaped corral.
For active people, suitable models without wires – headphones can be inserted in the ear; they will not interfere and confuse. Conveniently, such accessories are often equipped with a player and a memory card. Thanks to this, you can not fill the memory of the phone with music. Many wireless headphones can answer calls with a sensor – you don’t have to take your phone. Of the cons – headphones are more expensive than wired.
What influences acoustic design and noise cancellation
According to acoustics, headphones are open and closed types. You can determine the view by the cup: there are sound conductive holes in the open, but closed ones are not. The advantages of the open type in that the headphones sound more natural, do not strain the ear and, allow you to hear everything going on around you. In closed headphones, with more powerful bass, no foreign noises can be heard.
If you want the external sounds not to be heard, it is worth looking at headphones with active or passive noise cancellation. The active way is in open-air headphones. In this way, the hidden microphone catches background noise, converts it into electrical signals, processes, imposes unwanted acoustic vibrations, and gets a clean sound. The downside of such a system is that with active noise cancellation, the sound deteriorates and becomes not so high-quality. The passive way can be in open and closed headphones. In this way, background noise is reduced by the design of the accessory cups.
What type of attachment is more convenient
The accessory can be placed above the parietal area of the head – in this case, and the headphones should have a headband. To secure the headphones, they must fit tightly to the head. To do this, of the three variants of the arcs – cast, sliding, and self-adjusting – you need to choose the right ones.
Another way is to fasten the headphones on the back of your head. Since the main load will have on the ears, you should choose lighter models.
You can also place headphones on the ears with a clip or an earlier. In this case, the size and weight of the accessory are also important, as it will have to be worn on the ears.
Smaller devices can be fixed in the ears with silicone plugs or foam earbuds. These headphones are more comfortable: they do not fall out of the ear and do not interfere; you can listen to music in any position.
Which headphone shape is more comfortable
The shape of the headphones depends on how they will lie in the ear and how clean and deep the sound will be.
Earbuds fill the ear, while you can not arrange them very deeply, so the impact on the hearing will not be strong. However, because of the shape, this model is not suitable for every person and periodically can fall out of the ear. Also, in such headphones, you can hear what is going on around you. For music lovers, it is a significant disadvantage for those who need to hear what is happening on the street; on the contrary, plus.
More comfortable are vacuum headphones. They’re also called plugs. They are equipped with soft silicone nozzles, and they can be inserted deep into the ear so that sound insulation will be good. The sound quality in these headphones is much higher – they do not hear external noise, the music sounds pretty clean. However, often listening to loud music in such headphones is undesirable – they can plant a rumor.
Overhead headphones can be fixed on the ear, on the back of the head, or headband. This accessory is more suitable for gamers: they will immerse themselves in the atmosphere of what is happening on the screen. Overhead headphones will also suit active people – the device fits tightly to the ears, so it will not fall from the head and gives a good soft sound that will not spoil the hearing.
Full-size headphones also fully cover the ears. Pros are the same as in overhead headphones: the sound is clean, voluminous, the accessory is convenient, and does not overload the ear of the cons – dimensions. Such devices are not very comfortable to carry with you, so they are better to use at home.
The shape makes custom headphones of the ears – they are filled with a fast-hardening material, and after a couple of minutes, it turns out a cast. It is processed, covered with a special means, and makes the body of a photopolymer. The earpiece is filled with emitters, filters separating frequencies, the body is sealed. Such headphones will not just fall out of the ear at the wrong time; they do not miss the external noise even in the most crowded places and do not have to put the maximum volume. The design of headphones can be made to your liking. Since the shape of the headphones repeats the shape of a particular ear, you will not listen to music with a friend.
What’s the difference between open and closed headphones?
The first isolate the ear or ear canal from external sounds; the second, on the contrary, will allow you to hear the world around, without isolation and earbuds. Open headphones are easy to work with: you talk to the customer and hear what’s going on in the office.
Closed will be able to throw the outside world aside: for example, in the subway will be heard a small rumble, and music will not spoil the noise of cars or the knocking of rails.
What you need to know about the frequency range and sensitivity of headphones
When choosing headphones, you should pay attention to the range of frequencies – the wider this option, the greater the range of sounds. Standard – 20 to 20,000 Hz. Simultaneously, everything above this value, the human ear will not be able to perceive, so the headphones must cover exactly the standard range.
The volume of the headphones depends on the sensitivity. The standard value is 100 dB. The earbuds and vacuum earbuds are highly sensitive, as they have a small diameter membrane and a low-power magnet.
What else should be in the headphones
Many headphones are equipped with volume control. This allows you to adjust the sound without pulling the phone. Regulators can be on one of the headphone’s bowls or the wire. In some models, you can switch music and answer calls with this regulator.
An important detail in headphones – a microphone, because you often want to listen to music and communicate. The most popular model of the microphone is in the form of a capsule: a small oval with a button to switch songs and make calls. It is usually built into one of the wires and almost does not stand out. Less often, you can find models with a retractable and long microphone, which can be lowered to the mouth, as in the pilots or call center operators.
What additional features to look for
Some headphones have a multi-channel option. Thanks to her, you can hear the slightest sounds. This feature gives a good immersion effect when playing and watching movies.
More expensive models are waterproof. They withstand the effects of rain and sweat.
The headphones, which connect to the phone via Bluetooth, have an NFC function. It allows you to share information with other devices: video, photos, and music. This option is quite convenient if several people want to listen to music from one phone or watch a video.
Headphones can also be fitted with a vibrating spine. This mode is convenient if you want to keep quiet, and it is important to know when someone calls the phone.
A handy option in headphones is LED. It shows the level of charge, loss of signal, and the phone mode, which can change the color and period of radiation.
What is affected by resistance, power, and level of distortion?
The volume is also affected by the resistance of the headphones. The same headphones on different devices will sound different. If you connect studio headphones with 250 Om resistance to the player, they will play quietly. For the phone and portable equipment, it is necessary to use devices with lower resistance – up to 16-32 Om; for stationary equipment – from 32 Om.
Depending on the power, you can adjust the maximum volume of the headphones. The power range ranges from 1 to 5000 MW. The power of headphones should be looked at if you want to listen to music from a high-quality device. Then the sound will be richer. If you plan to include music on your phone, the sound will not be so bright.
The sound quality depends on the level of distortion of the headphones. In models with a less than 0.5% distortion rate, the sound will be much better than in accessories, where the ratio is more than 1%.
