Which headphone frequency range is better? Everything you need to know about headphones

As we know, knowledge is power, especially in technical matters. The main characteristics of the headphones, usually indicated on the packaging, give an idea of ​​their capabilities before listening. You just need to figure out what's what.

Sensitivity

Everyone has encountered a situation where some headphones sound louder than others, even though the level on the player (or smartphone) is set the same. This fact is often associated with the difference in headphone power. But headphones are not an amplifier; such a premise is fundamentally wrong.

In fact, how loud the headphones will sound depends on their sensitivity. Traditionally, this parameter lies in the range of 90–120 dB, and for most models available on the market this range is already 95–105 dB. Sensitivity shows how loud the headphones will play, all other things being equal. The higher it is, the higher maximum volume and less load on the built-in amplifier of the player or smartphone. I noticed another direct relationship: the cheaper the headphones, the less likely it is that their real (and not indicated in the technical data sheet) sensitivity will be high.

Power

But when it comes to power, you shouldn’t chase watts. Especially when the main source of music is a smartphone or portable player. With high sensitivity, a few milliwatts are enough for the music to play loudly, and the gadget’s amplifier is not overloaded and uses up battery power sparingly. Yes, if you choose headphones with high power, the sound will probably (just maybe) be solid and punchy. But this will not last as long as you would like - the gadget’s battery will begin to discharge rapidly under such a load. Moreover, there are often cases when the built-in amplifier simply cannot cope with powerful headphones. As a result, you won’t hear a good sound (loose, shallow bass), and you’ll get distortion at volumes above average.

For headphones used at home, high power is no longer a problem, because it is assumed that they will be used with a stationary amplifier. Then high power will contribute to high sound quality.

Resistance

Another factor that significantly affects sound quality, energy consumption and generally determines the compatibility of headphones with the amplifier part is impedance. From the point of view of physics, impedance is somewhat different from the more understandable term “resistance,” but from a consumer point of view this is not so important, so it is quite possible to find such writing on the packaging of headphones.

Any amplifier has a certain range of loads with which it is capable of operating optimally. The impedance of the headphones, measured in ohms, accordingly determines the operating mode of the amplifier. Portable equipment usually contains amplifiers designed to operate with an impedance from 16 to 32 ohms. Therefore, these are the numbers you will find in most headphones. However, it is quite acceptable to use headphones with an impedance of 40–60 ohms with portable equipment. The fundamental difference is that the latter will require more power to operate, which means battery consumption will increase. Also remember that if the headphone impedance differs significantly from the recommended one, the amplifier will operate in a “freelance” mode, which may result in distortion and a general decrease in sound quality. And in extreme cases, it will also lead to failure of the amplifier or headphones.

High-impedance headphones, whose impedance amounts to hundreds of ohms, should only be used with stationary amplifiers. Most often, high-impedance headphones are made for professional purposes, although they can also be found among expensive high-end models for home use.

Attention, if you choose a model for home: the impedance of the headphones must fall within the recommended load range, which is indicated in the technical data of the amplifier. In general, most headphones and amplifiers are quite clearly divided into low- and high-impedance, so there shouldn’t be any particular problems finding a suitable pair.

Frequency range

The frequency range of headphones is probably the simplest and most understandable value. The wider it is, the better the sound. If the factory settings go beyond the audible range, for example, 5 Hz - 25 kHz, it indicates that the edges of this very audible range will be reproduced without much loss. Maybe because this is a simple value, and even with large numbers, manufacturers tend to embellish it. There are often standard numbers such as 20 Hz - 20 kHz. And no indications about the conditions under which the measurements were made, not to mention the frequency response graph. 20Hz can really be there, but with such a volume that only instruments in a deaf acoustic room, where perhaps (just perhaps) the measurements took place, will hear them.

Ears versus numbers

In conclusion of the review of the main characteristics, I want to save readers from one common illusion that “headphones with the same passport data sound the same.” Not at all.

With the same frequency range, the same sensitivity, power and impedance, different headphones will most likely play completely different from each other. Since our impression of the sound is formed by the accuracy of the response of the emitter, the shape of the frequency response and a number of other indicators that are published by developers extremely rarely, while others cannot be measured at all. Unfortunately or fortunately, modern measuring instruments have not yet reached those heights when they learn to perceive a musical signal in a complex manner, like a person. Therefore, having studied the characteristics for compatibility with the rest of the equipment set (source, amplifier), weighing their cost against your wallet, you still need to go and listen to them. There is no other way.

Wireless headphones are used for listening to music, gaming and computer activities. Features of the products: independence from the computer and phone, the need for recharging, large range.

How to choose wireless headphones

• Pay attention to the type of headphones: earbuds, earplugs, on-ear, monitor.

The classification is based on the distance the speaker is located to the ear. In-ear headphones are small in size, held in the ear by elastic force, but have poor low frequency reproduction.

Vacuum headphones provide clean and high quality sound and have a soundproofing effect, so they are used for listening to music in transport and noisy rooms. The disadvantage of such products is the high load on the ears.

• On-ear headphones with a special mount are suitable for gamers; they are expensive. Full-size devices cover the ears completely, can be closed or open, and provide good sound insulation. Disadvantage: large dimensions.
• Choose headphones depending on the purpose. To listen to music, you will need compact devices with a good playback frequency.

Gamers and recording studio workers are recommended to buy full-size closed-type ones. For sports, models with moisture resistance and frost resistance are required.

• Be sure to consider the size and weight of the headphones. The most compact are earbuds and vacuum devices weighing 5-30 grams, overhead models weigh 40-100 grams, and monitor models weigh 150-300 grams.
• Duration of work is another important criterion.

  Good models provide operation without recharging for about 30-40 hours, and work in autonomous mode for 2-4 days.

This indicator depends on the type and functionality of the device. Optimal time for recharging – 2-3 hours.

• Pay attention to the package contents of the product, the presence of a warranty card, and instructions for use. Buy devices from trusted manufacturers.

• Buy headphones with high frequency sound reproduction. As a rule, our ear detects frequencies from 15-16 Hz to 18000-20000 Hz.

In order to listen to the entire spectrum, choose models with a frequency of up to 20 GHz. High frequencies are harmful to the human ear.

• Pay attention to the sensitivity of the device. The standard indicator is up to 100 dB.
• The resistance characteristic for portable equipment ranges from 16 to 50 Ohms. The impedance for a computer is 32-80 Ohms; for working in the studio you will need headphones with an impedance of 200-300 Ohms.

The power of the model should be from 1 mW to 5000 mW.

• Sound distortion is a characteristic that determines sound quality. Choose products that distort sound by no more than 1 percent.
• Pay attention to the shape of the model of overhead and full-size products; they should fit tightly on the head, but at the same time be comfortable. To do this, select devices with a streamlined shape and durable mount.
• When choosing headphones for your computer, consider the presence of a microphone and volume control.
• It’s good if the products have a noise-absorbing effect, then nothing can distract you from your favorite activity.

• Choose the color of the products and design according to your preferences, it doesn’t matter.
• As a rule, modern models designed to operate within a radius of 10 meters. This indicator is quite sufficient. But headphones for a metal detector should have a higher performance – from 20 meters.

Most modern smartphones (and simple mobile phones) come with a wired headset (headphones), but not every pair of standard headphones can boast clear sound, comfort, and even less design. Listening to music, audio books, radio and watching your favorite movies on your smartphone will be much more enjoyable if you choose the right one.

First, you should decide on the type of headphones: in-ear, in-ear (they are also called “plugs” or “plugs”), on-ear (there are many folding models among them; sometimes they are called arc), and monitor. In addition, headphones can be wired or. The most suitable earbuds for your phone are small-sized in-ears and on-ears. Each of these types has its own advantages: invoices provide more volume and high quality sound due to the larger membrane, but they are not as compact as plug-in or overhead ones; in-ear headphones are comfortable and affordable, but if you choose such headphones that do not fit the shape of your ear, they can fall out of your ear, which is inconvenient; cork “plugs,” on the contrary, sit very tightly in the ear, but not everyone is comfortable wearing such headphones, besides, doctors do not recommend using them for a long time, this can affect your hearing aid, another important fact- on the street you may not hear anything except your music, which can be dangerous if, for example, you are riding a bicycle.

To understand which type of headphones is best for you, think about where you will most often use them with your phone. If they need to be invisible and take up little space, then it is better to choose in-ear or plug-in ones. For long trips and trips, overhead headphones are more suitable, as they make your head and ears less tired.

Some headphone models were originally designed specifically for mobile phones, such as . When buying headphones in an online store, carefully read the description, and then you will definitely make right choice.

Headphone weight

Headphone weight. If for large home headphones weight does not matter the most, then for a telephone, the lighter they are, the better. Wired ones are always lighter than wireless ones, since the weight of the latter is affected by the presence of batteries. “Earbuds” usually weigh 5-30 grams; overhead - 40-100 grams.

For connoisseurs of quality sound

The standard jack is 3.5 mm. However, in some mobile phones and voice recorders you can find a 2.5 mm jack. Often, headphones come with an additional adapter for 2.5 and 6.3 mm, which is very convenient.

Gold plated connector. You've probably noticed that some headphones have a gold-plated connector. So, the gold coating on the connector and adapter is not accidental. Gold plating is resistant to corrosion and oxidation. Good contact- cleaner and higher quality sound.

Important technical characteristics of headphones

Membrane diameter

The diameter of the membrane, or the size of the speakers. This indicator affects the sound quality. A larger diaphragm diameter better reproduces low frequencies. Again, when choosing headphones for your phone, you are unlikely to plan to buy large monitor headphones. The standard for in-ear headphones is a membrane with a diameter of 9-12 mm. For example, on-ear headphones for home use with good quality “low-end” they start from 30mm. Large studio headphones can be up to 70mm.

Impedance

Impedance, or the nominal resistance of the headphones according to alternating current. Technical characteristics. In general, for headphones this figure can range from 1.0 to 820.0 Ohms. And it depends primarily on what equipment you are going to use them with. For portable equipment, choose models with an impedance of 16-40 Ohms. This will ensure sufficient volume at low power input signal.

Band frequency

The frequency range can be specified by the manufacturer from 2 to 110000 Hz. It should not be forgotten that the human ear perceives from approximately 20 to 20,000 Hz. If headphones have a wider range, you may not notice the difference unless your ears are particularly sensitive.

Headphone sensitivity

Headphone sensitivity can be from 60.0 to 130.0 dB. Sensitivity affects the volume of sound in the headphones. Without going into the technical side of the issue, it’s worth choosing headphones with a sensitivity of at least 100 dB, which will ensure sufficient volume on the street and in noisy places.

Cord length

Cable length in wired headphones primarily affects their comfortable use. For a phone, the optimal length for headphones can be considered 80-120 cm, depending on where the phone will be: in a bag, jacket pocket or jeans pocket.

Replaceable ear pads

Number of pairs of replaceable ear pads included. Some headphones may have only one pair, while others may have 3. The number of ear pads that come with in-ear headphones can matter, since purchasing additional ones can be problematic. By the way, ear pads are removable parts of headphones that are directly adjacent to the ear. Sometimes there are pairs included different sizes so that the user can choose the size for themselves.

Additional benefits:

Waterproof housing. Yes, and the headphones are waterproof

Airplane adapter. If you fly often, you may find this adapter useful to connect your headphones in the cabin to use the internal audio system.

Anyone who buys cheap headphones is often forced to experience disappointment in their purchase. After some time, crackling, extraneous noise and other unpleasant effects appear in the headphones. Very often it becomes clear that headphones rub the ears, are uncomfortable and do not fit firmly on the head, and have a number of other negative qualities.

How to choose headphones that would satisfy your specific request?

To accomplish this task, you need to select headphones according to the following characteristics:

1. Frequency response
This characteristic greatly affects the sound quality of the headphones. If you notice hissing and a metallic tint to the sound at very low or very high frequencies, this is a consequence of the imperfections of the headphones in the frequency range.

As a rule, especially important role plays the low limit of the frequency response. If you are particularly passionate about sound quality, then it is better to choose headphones with increased quality sound quality - headphones with a large membrane diameter. Despite everything, almost none of the in-ear headphones with a diaphragm size of 9-12 mm are able to compete in sound purity with on-ear headphones or monitors with a diaphragm diameter of 30 mm and above, which allows them to significantly expand the frequency range and improve sound quality. The average frequency response is 18-20000 Hz. If the frequency range is narrower, you should think twice before buying such headphones.

2. Sensitivity
Sensitivity affects the volume of sound in the headphones. Perhaps this is not relevant for monitor headphones that always provide good volume, but when choosing earbuds or on-ear headphones “for the street”, this is worth paying attention to.

It is good 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. Try to look at what magnetic cores are used in headphones. It is not recommended to use in-ear headphones with a small membrane diameter and a low-power magnet. It is best to opt for headphones with neodymium magnetic cores.

3. Connection type
If you have decided that you are taking headphones for a large stereo system, then you are faced with the question: should you go with wired or wireless model? Let's consider their advantages and disadvantages.

For headphones with a wire, the disadvantage is obvious - the very presence of a wire that restricts movement. Even if you take a long wire, you will not be able to dance or walk around the apartment, enjoying music, without tangling it. However, in this case, you are always guaranteed the maximum sound purity that these headphones are capable of producing. It's different with wireless headphones. There is complete freedom of movement - some models provide such good sound transmission that you can listen to music while moving around the entire apartment. However, here special attention should be paid to the transmission quality, channel frequency and the presence of automatic adjustment.

Despite the fact that modern wireless headphones While both radio and infrared are capable of easily transmitting sound with minimal distortion, it is still worth paying closer attention to the above characteristics. Another disadvantage of this type of headphones is the battery. The battery life of the headphones should be long enough to provide many hours of listening time. Although, the most convenient in this case will be headphones with batteries that charge directly on the transmitter.

4. Acoustic design
Based on their acoustic design, headphones are divided into open and closed. Closed headphones do not allow any external sounds to pass through, while open headphones allow you to hear environmental sounds. Despite the fact that acoustic design is a matter of taste, it is worth warning that open headphones give a clearer picture, while closed ones create a slight resonance.

5. Convenience and comfort
The convenience and comfort of the headphones is another very important detail. There are lots of little tips to give here. If headphones rub your ears, do not use earbuds, but use on-ear headphones or monitors. To prevent headphones from spoiling your hair, use headphones with a headband located behind the neck.

Look at the weight of the headphones - even though they seem light at first glance, some models can cause discomfort after several hours of continuous use. Use in-ear headphones with a headband or other models that distribute their weight evenly. Pay attention to what the earcups are made of, how ergonomically they are designed, how well they can be adjusted to fit your head diameter, etc. The presence of a volume control on the cord, a storage box and similar little things can make life much easier and make listening to music much more enjoyable.

Headphones have a number of advantages and disadvantages compared to speaker systems. The advantage of headphones is that they are capable of providing a wide frequency range and delivering strong sound pressure without distortion at a much lower cost. In addition, the sound in the headphones is not affected acoustic characteristics premises, and powerful sound, in turn, does not get on your neighbors’ nerves.

The disadvantages of headphones include the unnatural presentation of spatial information. The fact is that when you hear sound in a room from acoustic systems, each of your ears hears sound not only from the emitter closest to it, but also from the one farther away. It is based on this information that a person can determine the location of the sound source in space. In headphones, each ear perceives only sounds coming from the emitter intended specifically for this ear, which ultimately leads to unnatural sound and, as a result, increased fatigue. True, there are devices called head speakers that are free from this drawback. These include the AKG K 1000 model.

There are headphones that are inserted into the ears and headphones that are worn on the head. Professionals classify headphones inserted into the ears (earbuds) as stereophones. entry level. This is explained simply: despite their apparent convenience, there is a clear drawback - low quality sound, in particular the weakness of low frequencies. Manufacturers are unsuccessfully trying to correct this through various technical tricks, such as ear tips in the SONY MDR-ED228LP headphones, or high-power neodymium magnets (400 kJm3) in the SONY MDR-EX70 headphones. But it is impossible to extract a wide frequency range from a 9 mm membrane while maintaining the small size of the headphones. Headphones with such technical gadgets will indeed sound louder, but never better quality.

However, it should be noted that the real advantage of earbuds is their compactness and ease of use (they do not wrinkle your hair, do not take up much space, are almost invisible, etc.). A subtype of this type of headphones are models with a thin plastic rim - earbuds with a headband. This model characterized by the presence of good (compared to all other earbuds) low frequencies, the headband is made of special plastic that will not break even during the most unimaginable operations with headphones. These headphones include SONY MDR-W08L. In addition, there are sports models of earbuds; they have an increased degree of comfort and ergonomics. These models function like glasses and can be easily adjusted to suit the individual ear characteristics of a particular listener. These headphones are produced by Bang & Olufsen.

Among the headphones worn on the head, there are two types - open and closed. Open-type headphones were invented by SENNHEISER and are stereo headphones that partially receive external sounds. Closed-type headphones are the most sealed models with minimal penetration of external noise.

Their disadvantage is a certain boominess when playing songs (similar to the effect in subwoofers). In general, when choosing headphones in a store, pay attention to the packaging. It shows the main characteristic of the headphones - frequency; the wider the specified range, the better sound in headphones. Thus, mid-range headphones SONY MDR-A106LP have frequency response 18 - 20000 Hz, they have a large membrane with a diameter of 30 mm, which allows you to achieve good bass. This type of headphones is not compact, but to minimize the size of the headphones when not in use, manufacturers use folding (as in SONY MDR-A106LP) and collapsible (as in KOSS KTX/4) arms.

Separately, there are currently popular headphones with an original design, the shape of which allows them to be hung around the neck, while the listener does not have to worry about disheveled hair, placing the headband on the back of the head. These headphones combine the ease of use of in-ear headphones (headphones inserted into the ears) and the good sound quality of on-ear headphones (i.e., worn on the head).

Headphone models with this design include AIWA HP-AJ40 and SONY Street Style. In addition, there are professional and semi-professional headphones that are used by either advanced audiophiles or music specialists. They are distinguished by thoughtfulness to the smallest detail and quality of workmanship, such as the PHILIPS HP-910. This model uses a dimensionless design that ensures an optimal fit; there is no need to twist or adjust the headphones to fit your head.

The bow consists of three elements: a flexible frame and two elastic ties. This design allows the load on the head to be distributed as evenly as possible, saving the listener from rapid physical fatigue. The inner surface of the earcups of such headphones is usually trimmed with either velvet or leather substitute, and the emitter itself is covered with acoustically transparent fabric. In the manufacture of a dynamic emitter (magnet of broadband heads), alloys of neodymium, iron and boron are used, which make it possible to achieve increased power. The voice coils are wound with either oxygen-free copper or copper-clad aluminum wire, and the membranes are made of Mylar. In addition, the connecting cords, the standard dimensions of which reach 3 meters, are made from several flexible long-crystal oxygen-free copper (LC-OFC) conductors. According to a mini-survey conducted on the RuNet, the majority of listeners who are willing to spend about a hundred dollars on headphones choose this type of stereo phone.

We should also focus on wireless headphones. There are two ways to transmit a signal from the base unit to the headphones. The first of them is using a radio signal. The principle of operation is simple: the base unit contains a radio transmitter that operates in FM-stereo mode at frequencies of 433-435 MHz. The base unit is connected on the one hand to the output of any source (CD, MD, etc.), and on the other hand to the network via a standard AC/DC adapter. The radiation pattern of the transmitter antenna is circular and allows you to maintain stable connection headphones with a base station within a radius of about 100 meters, and, as a rule, there is a function manual settings systems.

This type of headphone includes the PHILIPS HC 800 model. The second method of transmitting a signal from the base station is through the infrared port. In this case, the signal is transmitted according to the remote control principle remote control to the TV and only at a line of sight distance. The advantages of wireless headphones are obvious: freedom of movement around the apartment, office, country house- but there are also disadvantages: noticeable noise when listening to songs, frequent replacement of batteries (standardly two AA batteries are enough for four hours of listening), inability to listen to headphones with infrared port in the next room.

Those who believe that headphones are the simplest devices capable of only receiving and then technically reproducing a signal from a source are deeply mistaken. There are headphone models, like SONY MDR-DS5000, capable of reproducing not only analog, but also digital signals(for example, multi-channel accompaniment to a film, or connection via optical output DVD Player), and not only in Dolby format Pro Logic, but also in AC-3. The MDR-DS5000 base unit contains a digital-to-analog converter, AC-3 and DPL decoders, a phase-frequency correction circuit, an IFC encoder and, finally, an amplifier.

The full name of headphone amplifiers is Headphone distributing amplifier. Amplifiers are used not only to simply increase the power of the signal from the source, but also to distribute the signal to several pairs of headphones. Amplifiers are usually used in studios to supply each listener with an individual power signal, while everyone can listen to the sound as loudly as they want without interfering with the quality and volume of the sound of their neighbors.

In conclusion, it is worth noting that the choice of headphones is a purely individual matter, and depends both on the purpose of the purchase and on the taste of the buyer. But if you want to get really high-quality sound, and have the funds for this, you should forget about three-dollar Chinese counterfeits and buy only branded products.

But it wasn't without its drawbacks. Vacuum headphones create unnecessary stress on the hearing aid, since they need to be inserted quite deep into the ear canal. It is believed that if you do it often, you can damage your hearing.

How to choose good on-ear headphones

It’s not even worth explaining in detail why they were named. It's simple - the headphones are literally placed on your ears. Their design is also more than standard - a headband with fastening and adjustment, earcups, a wire (optional).

Let us immediately note their main advantage over the two previous types. Due to larger size membranes will sound better. This type also has improved sound insulation. So, overhead “ears” are also suitable for non-demanding music lovers.

Just as a note, let's add that there are excellent ones. In terms of price, they will be even cheaper than in-ear ones.

How to choose good monitor headphones (aka full-size ones)

In the title, we have already clarified that this type is also called full-size - the design is such that it completely covers the ears. However, we should immediately note that monitor headphones are divided into open and closed models. Closed ones are suitable for those who want complete isolation from the outside world. Open type monitor headphones have holes in the ear pads in their design.

The closed type of these headphones is chosen mainly by musicians or directors, so that they can observe the entire range, avoiding any extraneous noise. The open type is mainly chosen by music lovers, gamers and simply those who value high-quality sound.

The biggest disadvantage of these headphones is their size. You can't run around with them on a walk, so take this fact into account. You can listen to music only at home, without unnecessary sudden movements. The second drawback, although this is not a drawback, but a feature - quality headphones well-known manufacturers (Koss, Sennheiser, AKG, Audio-Technica) will be expensive.

How to choose good headphones with a microphone

We decided to talk separately about models that have . And let’s immediately note their varieties: condenser, dynamic and a subtype of condenser – electret. Capacitors do a better job of transmitting sound than others, but they have a requirement - separate power. However, you should not expect the same results as from professional microphones.

Also remember that you cannot speak unambiguously about the quality of sound recording with a microphone without a specific sample in hand. The type of microphone, of course, affects certain nuances of the recording, but much more influences the quality of the microphone that the manufacturer has built into the headphones. Therefore, you need to read reviews for each specific model headphones to find out how the microphone works in them.

USB headphones are gaining popularity now. Their main difference from regular models is that the DAC and ADC are built into the headphones themselves and the sound quality, as well as the quality of sound recording, depends on the headphones themselves, and not on the sound card of your computer. USB headphones often come with special drivers and programs that need to be installed on the computer in order for the headphones to make the most of their capabilities. All this affects the quality of sound and recording.

It is important to note that microphones can be omnidirectional or unidirectional (main types). Unidirectional will catch sound better, without loud noises, but it is important to install it in the correct position. If you have already decided to buy headphones with a microphone, then ask if there is a built-in noise reduction system.

Unidirectional microphones are most often used in gaming models headphones. Omnidirectional for musical models. Their main difference is reflected in the name. An omnidirectional microphone picks up sounds from all directions equally. A unidirectional microphone is better at picking up sound from your mouth, but less likely to pick up sound from your surroundings.

Wireless headphones

Without fail, we decided to talk separately about headphones with wireless interface, but there is quite a choice here:

• models with Bluetooth support;
• working via radio channel;
• working via IR channel.

Bluetooth headphones

This is the most common option. Typically, their range is limited to 10-12 meters, but we can talk about a low level of distortion. In more expensive models there is even support for special technologies for noise reduction and improving sound quality.

Resistance (impedance)

This parameter is measured in Ohms. It is imperative to take this into account when choosing headphone models, as this affects the sound quality depending on the source. If you have a pocket player or smartphone, then you should choose headphones with an impedance of 16-50 Ohms. But keep in mind that the higher the impedance, the more powerful the incoming signal must be, otherwise the membrane will be difficult to swing.

For example, head-mounted monitors often require a powerful sound source. Studio headphones generally have an impedance of about 250-500 Ohms and require a special amplifier. But note that the higher the impedance, the cleaner the sound will be. Inexpensive low-impedance headphones often have noticeable distortion.

Impedance is the nominal resistance at the headphone input. The term impedance is borrowed from the word impedance, which translates as total resistance. Often used as a synonym for headphone impedance. Impedance is a combination of resistive and reactive components, resulting in the level of resistance depending on frequency. In most cases, low-frequency resonance for dynamic headphones can be observed in the graph.

You need to choose headphones based on resistance in accordance with the technology with which you are going to use these headphones. For use with portable equipment, you should select headphones with a lower impedance, and for stationary equipment, with a higher one. Portable amplifiers have a strictly limited output voltage level, but as a rule, the current level does not have a strict limitation. Therefore, it is possible to obtain the maximum possible power for portable equipment only with low-impedance headphones. In stationary equipment, as a rule, the voltage limit is not so low and high-impedance headphones can be used to obtain sufficient power. High-impedance headphones are a more favorable load for the amplifier and with them the amplifier operates with less distortion. Low-impedance headphones are considered to be headphones up to 100 ohms. For portable equipment, headphones with an impedance of 16 to 32 ohms, maximum 50 ohms, are recommended. However, if the headphones have high sensitivity, then you can use a higher impedance.

Power

Usually the permissible power range is indicated on the box - from 1 mW to 5000 mW. If the power goes beyond the upper limit of the range, your headphones will instantly fail.

When it comes to power, don’t chase watts. Especially when the main source of music is a smartphone or portable player. With high sensitivity, a few milliwatts are enough for the music to play loudly, and the gadget’s amplifier is not overloaded and uses up battery power sparingly. Yes, if you choose headphones with high power, the sound will probably (just maybe) be solid and punchy. But this will not last as long as you would like - the gadget’s battery will begin to discharge rapidly under such a load. Moreover, there are often cases when the built-in amplifier simply cannot cope with powerful headphones. As a result, you won’t hear a good sound (loose, shallow bass) and will get distortion at volumes above average.

For headphones used at home, high power is no longer a problem, because it is assumed that they will be used with a stationary amplifier. Then high power will contribute to high sound quality.

Distortion level (non-linear distortion)

Of course, headphones may create slight distortion when playing sound. This parameter is measured as a percentage. The smaller it is, the higher the sound quality. The norm is now considered to be between 0.5% and 2%.

Selecting headphones depending on the sound source

Headphones for player

Today, almost any conscious purchase music player involves lengthy searches necessary information online. Let's say you read hundreds of reviews, consulted with professionals and bought a player from a well-known brand.

Typically, such players come with headphones, so that the package includes “everything at once.” After you have charged the battery and read the instructions (which is necessary), you connect the headphones and press Play. We think that you will be immediately disappointed, because the player may be of high quality, but it often comes with an inexpensive accessory.

For such players it is usually choose good headphones liners or vacuum– all because of the characteristics of the player itself and its compactness. We talked about the characteristics separately above.

If we combine everything that we indicated above, we get the following picture:

• Form factor: in-channel or overhead;
• Resistance: from 16 to 32 Ohms. Headphones with a higher impedance will work, but you won't get good sound from them;
• Power: for in-ear headphones, a power of 30-40 mW is sufficient, for over-ear headphones from 300 mW and above.

Headphones for smartphone

Headphones for phones are chosen in almost the same way as for pocket MP3 players. There is only one caveat - we often choose not just headphones, but a headset so that we can comfortably talk with the interlocutor. Therefore, pay attention not only to the characteristics and sound quality of compact types of headphones.

Test the microphone in advance - it's even better to call someone and ask about the sound quality. Best option– earbuds or vacuum with a microphone with a standard 3.5 mm jack.

Headphones with microphone

We’ll highlight this option separately, since not only headsets for phones can have a microphone. These headphones are often purchased for communicating on Skype or for online games. There are models in which the microphone is rigidly connected to the headphone structure, but there are options with a detachable microphone. This type is suitable for those who do not often talk on Skype.

As we wrote above, it is very difficult to give advice on choosing a microphone built into headphones. According to the technical data that manufacturers write on the packaging, it is difficult to talk about the quality of the microphone. You will either have to rely on luck or read a review of the headphones with a microphone that you want to buy. There is no other way.

Headphones for TV

More often than not, we need headphones for our TV to enjoy watching a movie. Therefore, the choice is limited to on-ear or monitor headphones with good sound insulation and a long cable (but wireless ones are also possible).

• Form factor: overhead or monitor;
• Frequency range: the wider the better, but not less than 20-20000 Hz;
• Sensitivity: preferably at least 100 dB;
• Resistance: from 16 to 64 Ohms. Headphones with a higher impedance will work, but you won't get good sound from them (when connected via wire). If you buy wireless headphones, you don't need this option, because... the headphones are perfectly matched to the base from which they will receive the signal;
• Power: from 300 mW and above. However, remember that listening to loud sounds or music for just 5 minutes can have a very detrimental effect on your hearing, even to the point of irreversible damage. Please do not listen to headphones at full volume.

For computer

Choosing headphones for a computer is not difficult, and in general, headphones for a computer are the same as for any other equipment. But there are some nuances. If you are choosing headphones for gaming, then the best result can be achieved if you buy comfortable music headphones with good sound. Believe me, they will sound better in games, and in some cases much better than those headphones that manufacturers proudly call “gaming headphones.” IN gaming headphones the main emphasis is on the low frequencies, quite often they are so strongly emphasized that the mid and high frequencies fade into the background. This may seem impressive, but only for the first 5 minutes. If you play with these headphones for hours, your head and ears will very quickly get tired of such sound.

Also, gaming headphones are often equipped with a microphone and it also does not shine with quality. Yes, it will work, but best quality You can record speech using a lapel microphone, which can be bought at any computer store for 200-400 rubles. It will not look so pretentious, but they will hear you better. Of course, there will always be an exception, and perhaps there are gaming headphones out there with an excellent microphone, but I haven’t held them in my hands yet.

• Form factor: in-ear, overhead or monitor;
• Frequency range: the wider the better, but not less than 20-20000 Hz. Please note that on many gaming headphones this range is narrower. This is because the main emphasis in them is on low frequencies, and not only do even those high and mid frequencies that the driver can reproduce fade into the background, but the manufacturer also configures the headphones in such a way that they have no headroom for high frequencies. frequencies for their correct reproduction;
• Sensitivity: preferably at least 100 dB;
• Resistance: from 16 to 32 Ohms. Depending on what sound card used in your computer, you can buy headphones with an impedance of up to 600 ohms. But this is possible if the instructions directly state support for such headphones. If you did not buy a separate sound card or do not know which card is installed in your computer, feel free to buy headphones with an impedance of up to 32 (50) Ohms maximum;
• Power: for in-ear headphones, a power of 30-40 mW is sufficient, for over-ear headphones from 300 mW and above. However, remember that listening to loud sounds or music for just 5 minutes can have a very detrimental effect on your hearing, even to the point of irreversible damage. Please do not listen to headphones at full volume.
