As the saying goes, one point is worth the price. This is a basic principle and can be said to be applicable to any commodity. Expensive headphones are generally better than cheap ones, and they have the reason to sell them at a high price. However, many people think that the sound quality of your headphones is even better. In fact, there are too many factors affecting the price of headphones. It is not only the sound quality, but also the effect from the brand itself or the design. The sound quality of your headphones is good. It should be, but it is not necessarily that some headphones are cheaper than it is, so it may not be excellent.
On the other hand, the sense of hearing of headphones is a subjective factor. This is difficult to determine. Different people like different sound performances. Maybe some high-end headphones are not suitable for some people's sense of hearing, even if it is expensive. Can't please his favorite. High-end HiFi headphones are generally designed for music enthusiasts. Most people don't have the high quality requirements for headphones, and some subtle qualities are generally not available to the human body. Choosing a headset that can satisfy you may not be It takes so much money, and the right one is the best.
The following is a description of the classification and frequency of the sound quality:
Dull: This kind of sensation is given by the frequency of about 20 Hz, and when it is higher than 80 Hz, the sound will be thicker, so the sound with dullness is generally low, and there is very little overtone component. The instrument source with this pitch characteristic is generally the bass area of ​​the bass instrument.
Heavy: From the perspective of sound sensitivity, the heavy feeling is the unique sound effect at the 80 Hz frequency point, and from the sound pattern characteristics, the short bass sound type musical instrument has a stronger sense of gravity.
Low: Low is often used to describe a slightly richer sound. His fundamental frequency may be the same as a dull sound, but most of its higher harmonics are more abundant than dull sound.
Deep: This is an emotional adjective, often used to express the color of the "loose" low frequency response, the fundamental frequency is slightly higher than the low sound. Generally with deep sense of the instrument, the most typical is the cello and the bass area.
Thickness: This kind of sound is a characteristic of a wide-spectrum sound source, so the thick sound is generally a sound source with a low fundamental frequency and a wide spectrum.
Thickness: Thickness refers to the low-frequency sound with high integration, and the typical sound source with a thick sense is the low-range of the celesta.
Plump: This is the sound characteristic of the sound source with a frequency between 100 and 250 Hz. Generally speaking, the sound source in this frequency band will inevitably have rich sound effects.
Generosity: If the spectrum is wider, a richer sound will be produced.
Full: This is a kind of low-frequency sound called strong, and the electric bass with the effect of “vortex distortion†is generally added. This sound characteristic is very obvious.
Bright: Generally, when the fundamental frequency of the music is higher than 500 Hz, it will become brighter. Even when it is as high as 7500 Hz, we can't say that it is not bright, so the brightness of the sound source is a relatively general. adjective. The brightness is most noticeable at 2800 Hz.
Loud: It is often used to describe a high-definition sound with a neck, and when the spectrum is above 4000 Hz, the sound source does not have this pitch characteristic.
Hongliang: A high-bright sound with a certain fusion.
Rounded: refers to a softer, high-brightness sound.
Soft: Compared with roundness, the softness is more dull and is a relatively low-brightness sound.
Crisp: Sounds with a spectrum between 4000 and 8000 Hz generally have a certain crisp effect.
Sorghum: refers to the high-penetration crisp sound, and the typical instrument with this phonological feature is 唢å‘.
Sharp: The sound of the spectrum concentrated around 6800 Hz is generally sharp and harsh.
Sharp and sharp: If you have a sharp sound with a similar distortion, you can produce a sharp sound effect.
Slim: Music with a spectrum above 8000 Hz generally has a slender sound effect.
Fusion: Soft sounds that are generally difficult to highlight have a certain sense of integration. Of course, all sources can be measured by the degree of fusion or non-fusion. In musical instruments, it is generally believed that the viola and cello have the best sense of fusion.
Cognac: This is an antonym of fusion. The high-frequency sounds that are generally lacking in harmonics and dissonant overtones have some degree of cognac. Among the instruments, he is mainly caused by the lack of resonance in the extremely high-pitched area.
Solid: A narrow-band sound system of around 600 Hz, and a short-sounding sound pattern, all have a certain sense of sound.
Void: refers to a dull sound with a "staining" effect, which is often used to describe the sound of a big wooden fish.
Warmth: This is a word that describes the color of the music. He is generally proportional to the "staining degree" of the sound. For example, the clock has a subtle sound.
Rough: If the low-frequency sound has an effect similar to overload distortion, it can form a rough sound.
Rough: Roughness is a rough sound with a slight sand sound. Generally, the trumpet and the horn have this vocal characteristic when playing the bass zone.
Hoarse: Specially made with a false "sound" sound effect.
Vigorous: This is an adjective with affection, generally refers to the hoarse sound in the lower frequency band, such as the bass area of ​​the big pipe.
Tension: This is the result of some special discordant overtones in the tone.
The sense of strength: the sense of strength in the low frequency band specifically refers to the sound in the 200~500 box frequency band, such as: the bass area of ​​Dagu and Dahu, the sense of strength is better. In the middle and high frequency bands, the sense of strength refers to the high-penetration, high-protrusion, soft-sounding sound. In the middle and high-pitched areas of the general high-pitched brass instruments, they have a good sense of strength.
Penetration: refers to the high-protrusion, high-brightness sound, the penetration is more obvious around 4500 Hz. Glimmer: refers to a high roundness sound with a certain sense of standing.
Sadness: Despair and warmth are anti-sense, and it is also a kind of emotional. The typical instrument sound source with this phonological feature is the midrange of the midrange oboe.
Gloomy: High-tension low-range sound can form a gloomy sound effect.
Flat: This is the sound effect unique to the 2500 Hz. Music near this frequency point is generally obviously "flat" feeling. Such as: Banhu, Erhu, etc., the second kind of sound characteristics are very obvious.
Darkening: If the spectral components above 6000 Hz are missing from the tone, the pronunciation can be made "dark".
Deficiency: This is caused by the increase in noise when the instrument is at a higher scale. This noise is usually similar to the airflow.

It is not easy to describe the abstract sound, but there is a set of adjectives that are customary. Some words are not very grand, but they can express feelings just right.
Warm: The sound is biased towards medium and low frequencies, and the residual sound is longer.
Cutting: The sound is thin, and the transition between high and low is not smooth enough.
Sweet: It is usually described as vocal performance, with outstanding IF performance and some reverberant tail sounds, and the sound is moist like a real person.
Dry: The sound has no aftertaste, like singing when the throat is dry.
Thick: The bass performance is more prominent, with the right amount of aftertaste, very hearty voice.
Fat: The frequency is slightly higher, the details of the performance are there, but the details of the lines are thicker.
Fast: The sound response is fast, and the fast performance is good. For example, when a calm sounds, a gunshot sounds, and the moment of response sounds fast.
Slow: The slow response is slow, like the performance of gunshots, the sound energy changes from low to high, and the transition time required is longer.
Hard: The transition between sound and temperament, the heights and undulations are faster, and the transition is not supple.
Mark: The middle and high notes are over-exposed.
Called: The middle and high notes are over-represented. It is usually described as vocal performance, singing like a karaoke.
Subjective listening sound
Generally, according to the three elements of musical sound quality, that is, the change and combination of loudness, pitch and pleasantness, subjectively evaluate various properties of sound quality, such as low frequency loudness for fullness of sound, high frequency loudness for bright sound, and low frequency for weak sound. The high frequency is weak and the sound is clear. In the following, several typical senses of hearing are introduced in combination with sound source, sound field and signal characteristics.
1 three-dimensional
The sound mainly consists of a sense of space (surrounding) of sound, a sense of orientation (direction sense), and a sense of layering (thickness), and a sound having these senses is called stereo. The various sound fields in nature are themselves three-dimensional, and it is the most important feature of the sound source. The De Boer effect proves that the physiological characteristics of the human ear are: the human ear is on the symmetry axis of the two sound sources. When the sound pressure difference Δp=0dB and the time difference Δt=0ms, the two sound sources are the same. There are two sound sources; when △p>15dB or Δt>3ms, the human ear feels that there are two sound sources, and the sound image moves to the sound pressure or the sound source before the lead, every 5dB sound The pressure difference is equivalent to the time difference of lms. The Haas effect further proves that when △t=5ms~35ms, the human ear feels that there are two sound sources; and when the near reflection sound, the lag direct sound or the time difference of two sound sources △t>50ms, even once The loudness of the reflected sound (also known as near or pre-reflected sound) or the lag sound is many times greater than the loudness of the direct sound or the leading sound, and the sound source orientation is still determined by the direct sound or the leading sound.
According to the physiological characteristics of the human ear, as long as the sound intensity, delay, reverberation, spatial effect, etc. are properly controlled and processed, the man-made manufacturing has a certain time difference Δt, phase difference Δθ, sound pressure. The sound state of the difference ΔP, and the state of the sound wave generated by the original sound source at both ears is exactly the same, and the human can truly and completely feel the three-dimensional sense of the reproduced sound. Compared with monophonic sound, stereo usually has the characteristics of sound image dispersion, proper volume distribution of each part, high definition, and low background noise.
2 sense of positioning
If the sound source is recorded after recording in left, right, up and down, front and back, the sound received and reproduced should be able to reproduce the orientation of the sound source in the original sound field. This is the sense of positioning. According to the physiological characteristics of the human ear, the maximum time difference between the first sound source and the direct sound of the two ears is 0.44ms-0.5ms, and there is also a certain sound pressure difference and phase difference. Physiological psychology proves that the 20Hz~200Hz bass mainly depends on the phase difference positioning of the two ears. The 300Hz-4kHz midrange is mainly positioned by the sound pressure difference, and the higher treble is mainly positioned by the time difference. It can be seen that the sense of positioning is mainly determined by the direct sound that first reaches both ears, and the one-time reflection sound that arrives at both ears and the reverberation sound that is reflected multiple times in all directions mainly simulate the spatial surround feeling of the sound image.
3 sense of space
The reverberation sound of one reflection and multiple reflections, although lagging directly to the sound, has little effect on the sense of direction of the sound, but the reflected sound always reaches the ears from all directions, which has an important influence on the size of the surrounding space of the auditory sense, so that the human ear is surrounded by the surround. The feeling is that this is the sense of space. The sense of space is more important than the sense of positioning.
4 sense of hierarchy
The sound is high, medium and low frequency, the frequency is balanced, the high-pitched harmonics are rich, clear and slender and not harsh, the midrange is bright and prominent, full and full without hard, the bass is thick and there is no nasal sound.
5 thickness sense
The bass is steady and powerful, heavy and not turbid, the high sound is not lacking, the volume is moderate, there is a certain brightness, the reverberation is suitable, and the distortion is small.
Hearing: like the sense of strength, brightness, presence, softness, tightness, and sense of width
What music to listen to
The sound orientation of each earphone is different. The sound of the two headphones will not be the same. Even the same brand of the same brand may have subtle differences, but this is the charm of the headphones. Everyone's listening preferences are also different from those of headphones. What kind of music you like is entirely your own personality and will not be the same as others. For mainstream music types, it is critical to pick a headset that is suitable for this style of music.
At present, most of the listening is mainly based on popular songs. This may not require strong analytical skills, but it requires good bass performance and excellent listening. Currently, most of the earphones on the market are for pop music, and what is the bass boost? More common. Some friends like to listen to the music of female voices, then this requires a high-frequency high-performance headphones, which is different from the headphones selected by dance music and rock music. The requirements of classical music are more comprehensive. Generally, high-quality headphones are needed, the resolution is strong, the tri-band performance is very good, the sound field needs to be wide, and many other qualities need to meet certain requirements, but the price may be much more expensive.
