Inscription: Writing on the headset is a lot of pressure, because Aunt Zhang's home of the sun's high-grade headphones too much, so that someone called three or four hundred headphones cheap headphones, in fact, for most young people, especially the student party, Three or four hundred yuan headphones are not cheap, but they are the longest and most serious listening to music, because they are not only listening, still learning, but also to sing for male or female tickets or student PARTY's ~ ~ ~ When you are happy, you have to sing, when you are not happy, you have to listen to the songs and learn to get better. You also want to have a bit of accompaniment, but you also want to rock and dance when you are entertaining, so the headset is almost a must-have EDC for college students. The landlord is not talented. He has always maintained a low fever status in music. He has not graduated from the student's passion for music for many years, but he has not yet been promoted to be a fan. Therefore, he has retained and used several hundred yuan headsets in his hands. He can also listen to music and sundry headphones he used in college. It is thought that we have some references for buying affordable headphones.
At present, there are many kinds of headsets on the market, but generally speaking, they can be classified as follows:
1. In terms of categories, common headphone products mainly include headphones and headsets. For the same brand of products with the same price, the headset is generally better than the headset.
The headset is a pure audio output device, mainly used in front-end devices such as mobile phones, tablets, and HiFi players.
The headset is a device that has both output and input. Headphones with a microphone are mainly used in computers and mobile phones.
2, from the functional point of view, headphones products monitor, HIFI, audio-visual, noise reduction, sports, portable and so on. From the perspective of listening to music, the performance of headphones with the same price is generally HIFI, monitor, portable, noise reduction, game movie, and sports.
The earphones that monitor earphones can restore sound the most, compared to full fidelity, the advantage is: the output sound is not rendered, so the sound inside the various details can be heard very clearly; the disadvantage is: too balanced, what to listen to Do not achieve the best results. HIFI headphones are the earphones best suited for listening to music. Products are rendered for a certain audio and the product is very targeted.
The audio-visual headphone is mainly an analog multi-channel design, and the sound positioning is clear. For example, in a CS game, a good headphone can determine the direction and distance of the gunfire.
Noise-reducing headphones are mainly designed to reduce ambient noise. According to the working methods, they are divided into active noise reduction and passive noise reduction. Active noise reduction is achieved through negative feedback and phase compensation of the circuit at the noise frequency; passive Noise reduction is achieved by surrounding the ear to form a closed space or using soundproof materials such as silicone earplugs to block outside noise. Compared with active noise reduction, passive noise reduction is better for high frequencies and noise reduction effect for low frequency noise is not obvious, but the price is cheaper.
The meaning of sporty headphones is that they are mainly designed for functions such as anti-dropping, waterproofing, and reducing the noise generated by headphones during the movement.
3, from the wearable way, there are head-mounted, ear plug, ear hanging type and other types. According to the sound insulation effect, in general, the head-mounted sound insulation effect is better than the earplug type, the earplug type is better than the ear-hook type, and there are also some special custom earphones, such as Huawei's aggressive noise reduction earplugs that were highly promoted last year. This effect is absolute. It's better than ordinary headphones. Special cases such as this are not enumerated, because customization often means that the price is relatively high ~~~.
There are closed and open style head wear. The advantage of the closed type is that the sound insulation is better (passive noise reduction), but barrel sounds and echoes are easily generated; the open type features the sound field more natural and atmospheric, but the sound insulation effect is poor; and the semi-open earphone performance is in between the two. between. Most monitor headphones, noise canceling headphones and a few portable headphones are head-mounted. Appearance mainly depends on whether there is a hole behind the headphone unit. In the figure below, the upper left side is semi-open type and the left lower side is open type; the right side is closed type.
Earbuds are flat and in-ear style. Flat-type headsets have been popular before, but because they are easy to fall off and the sound insulation effect is not in-ear style, the in-ear style is better because of sound insulation, and is more comfortable to wear (replaceable with different sizes of aprons) and not easy It became the mainstream, such as falling off.
The ear-hook type is precisely a fixed method. The earphone head may be a head-mounted headphone head, or may be an in-ear headphone head. This structure is mainly used for sports headphones.
4, from the pronunciation design point of view, divided into moving coil type, moving iron type, ring iron type, flat type, electrostatic type.
Our common earphones and earphones are mostly moving coils. This kind of structure is similar to a small speaker unit. Its advantage is that the sounding principle is close to the human eardrum, the sound is naturally resistant, and the low frequency is loose and comfortable; the disadvantage is that the larger the unit volume, the driving power. The bigger the requirement is for the front end. The advantage of moving iron type is that the driving unit can be made extremely small, the driving power is very small, the tone is transparent, the high frequency is excellent, and it is generally used to make in-ear earplugs. The disadvantage is that the frequency response is relatively narrow, the sound is not very unnatural, and the low frequency performance is poor. The ring type is a newly emerging technology in recent years. In the earplug, a combination of moving coil units and moving iron units is used to realize the complementary advantages of moving coil type and moving iron type. The disadvantage is that the technical difficulty is relatively large and the product price is on the market. The disparity is large, the quality is uneven, and there are fewer excellent products. The advantages of the flat panel type and the electrostatic type are that the sound quality is small, the response frequency is high, the amount of information is rich, and the dynamics are better. The disadvantage is that the headset is large in size, heavy in weight, difficult to drive, and expensive. This structure is generally used in monitor headphones and HIFI headphones. On the flat panel prices are generally more than 2,000 yuan, electrostatic type is generally more than 10,000 yuan. 
Personally think that : choose one hundred yuan headset, which is the price within the range of 100 to 300 yuan (this may be the price range most students can accept), generally should be based on dynamic, but also buy moving iron, but certain We must first try to buy in order to avoid buying low-cost, low-quality products. If the brand name is used, most mainstream brands have several entry-level headsets in this price range. Some non-professional headset brands have dynamic irons at this price point. Circle iron and other products, such as millet's ring-style headphones (but personal never used, do not know how effective), choice is still relatively large.
The landlord has used four earphones and two headsets since he came to university. They are: Panasonic Piglet Headphones, Apple Mobile Phone Headsets, Moto Phone Headsets, Sennheiser CX180, and AGK K44 and Rambler H850. Two headsets. With this simple slick look and parameters, the analysis of sound quality focuses on the next section.
1, Panasonic pig mouth headphones. This is the original earphone when I bought the Walkman in 2004. I used to have two pigs earphones of the same length and length. Unfortunately, the long money has been used for many years and was thrown away after the line breaks. This is a short section of the headphones used to connect the remote control line, the line length is only 75cm line, and the two headsets use different lengths of lines to enhance the stereo effect, the specific parameters of the product has not been found. However, this pig-type earbud is designed to be worn very well, is small and fits well with the ear, and is not easy to lose. Now Apple's mobile phone headset and moto phone headset more or less imitate Panasonic's piglet design.
As the classic earphones of the Walkman era, online Taobao seems to have sales, the price of 30 yuan, but the true and false unknown, to pay attention to identification when buying.
2, Apple phone original with wheat headphones (Apple EarPods). This headset was bought in 2013 and comes with the phone. It belongs to the second generation of Apple mobile phone headsets. Headphones have a microphone and remote volume control and can only be used on ipads, ipods, and iphones, but not on other phones, or on Apple Computers. Specific parameters are unknown, Apple's official website did not give.
At present, the official website sells for 228 yuan. There are many imitation goods on the market at present, and there are more than one hundred of them in price.
3, moto buds call music headphones. In 2015, I bought a moto phone with it. The biggest feature of this headset is the interface and computer output interface common, you can connect to use on the Macbook air, although the microphone function can not be used, but the microphone switch can be used to open itunes music, really surprised to find the ~ ~ ~. When I went out with a macbool air laptop, I liked to bring this headset. Although the sound quality is not very good, it's still much better than the thirty or twenty dollar headphones I bought on the market.
At present, Tmall International sells, and there are four colors to choose from ~~~~
4, Sennheiser CX180. This headset was purchased on Amazon.com for $199 in 2011. This headset has also been discontinued, but similar models such as the CX200 and CX215 are available online at prices of around $200. Because this earphone is an in-ear structure design and is small and exquisite, it is very comfortable to wear everyday wear and sports, and it is not easy to fall off ~~~~.
The following is its main parameters ~~~, its characteristics: less impedance, high sensitivity, resolution is also good (after the test).
5, AGK K44 monitor headphones. This headset was bought at Jingdong Mall in 2013. It has been discontinued. The characteristics of the elastic band design is more comfortable to wear, but the earmuffs are more rigid and not large enough, resulting in a closed but not fitting ears. The specific parameters are shown in the figure below.
6, Edifier H850. Before and after the purchase of 2014, the starting price is about 250 yuan. The appearance is characterized by the ear-paste design, and can be rotated to accommodate; the headband is a pull button adjustment, personal feel that the head is not comfortable with AKG's elastic band.
The following is a comparison of the earmuffs and other details, compared to Edifier's earmuffs softer, better fit.
Here are its main parameters ~~~. Compared with the AKG K44, the main sensitivity is much lower and the rated power is smaller.
In addition to the Apple headphones, these six headsets have a long use time. In order to complete this article, I have chosen some songs and music that I have listened to numerous times, and spent a day to make a systematic comparison.
1, the output volume comparison
Use moto x + 1 as a player for testing (don't Tucao, in fact, most of the student parties listen to music on the phone), say that the volume of the phone is set to a fixed value, and the volume that you hear with headphones from high to low is: The first high - Apple EarPods; the second highest - Sennheiser CX180; the third highest - moto buds call music headphones, Panasonic pig mouth headphones, AGK K44 (the three can not hear the difference in height); The fourth highest - Rambler H850. Among the six headphones, only the CX180, AGK K44, and Rambler H850 headphones can identify the parameters. The lowest impedance of the three headphones is the Sennheiser CX180 with an impedance of 16 ohms. Impedance size represents whether the headset is easy to push, and low impedance headphones are less than 32Ω, so it is easier to drive sounds. The AGK K44 and the Rambler H850 have the same impedance, but because the AGK K44 has a higher sensitivity, the sound is greater at the same output voltage.
2, vocal performance test
Bass Zhao Peng's "Boat Song" - Zhao Peng's vocal bass is extremely good. He also has the appropriate penetrating power on the basis of low-frequency alcohol deposits, and is also transparent on thick warmth. In the bass performance, the Rambler H850 is better than other headphones, can hear the magnetic beauty of the bass, with "Boat Song" for more than three minutes there are men and women singing, and high-pitched harmony, can hear three vocals in three At the level, the background music falls very low, just like the distant blurred background of the camera after focusing. Followed by Sennheiser CX180; The third is Apple EarPods, vocals are okay, but the drums are a little chaotic, and finally AGK K44, Panasonic pig nose headphones, background sounds okay, that is, harmony does not float up, feel vocal The level is not clear.
Alto Tsai, "Your Eyes" - Tsai Chin's mid-range voice is thick, vicissitudes, and rich in texture. In the midrange performance, the Rambler H850, AGK K44, Sennheiser CX180 are better than other headphones, voice vocal changes can be heard very clearly.
High-pitched Hayley Westenra's “Amazing Gracer†- Hailey Westerner is a soprano and song writer from New Zealand who is a classical high-pitched chanter in the Bible. The song was mixed with a tenor and a bass subwoofer in more than two minutes, and at the end there was a tone change (the tone was increased, similar to that of the opera). The best performer on the treble is the AGK K44. This time it is the Sennheiser CX180 and again the Rambler H850. The performance of the other three is similar.
3, the test of music analysis and on-site restoration
In terms of resolution, Wang Feng mainly listened to "Beijing Beijing" and Qu Yingting's "jar of love." Both songs are rock style. Rambler H850 as a whole is more simple in the bass, the level of performance is not good Sennheiser CX180, but in the control of high pitch than Sennheiser CX180; and AGK K44 overall sense of hierarchy is relatively poor, is the vocal comparison Outstanding; Apple EarPods vocals are not good, but the sound of drums and other restore well; Panasonic pig nose headphones, bass is too weak, can not hear the drum sound shocked the feeling of the soul; feeling vocal level is unclear. The moto buds call music headphones have the weakest resolving power.
✠Wang Feng "Beijing Beijing" - A personally familiar, more familiar song. After peaking, Wang Feng will have a similar echo trail, and the main melody drum has been reciting back and forth in the left and right ear channels, as well as the piano's heavy bass ~~~~ and harmony ~~~.
✠Qu Ting-ting "jar of love" - ​​This song is also selected by the familiar song.
On the performance of the live restoration, the applause of Hotel California at the end, AGK K44 feels that you are on the stage and is part of the eagle band performance team. Applause and screams come from all directions. The Edifier H850 and Apple EarPods give listeners the feeling that you are under the stage, applause and screams coming from you. Sennheiser CX180 gives you the feeling that you stand far from the audience and the stage. Suddenly one person ran over your ear and stung his ear. Panasonic pig nose headphones and moto buds call music headphones are nothing special.
4, the dynamic performance of the test
The song from the "Secret Garden" once in a red moon - in the music, the violin and piano as the main melody, the background incorporates Celtic (Celtic) folk music, small orchestral and harmonies.
From the "Bird of Paradise" track: a morning in corewell - this track is from the world's three major light music groups, one of the German James Rast band.
Selected from the “Rhapsody of the Forestâ€: elves of the night—there are fiddle, flute, guitar, percussion sounds, and squeaks of thunder, frogs, and dogs.
Light music repeatedly listened for 3 hours. The performance of the first two songs, mainly musical instruments, can only be heard on the sound of moto buds. However, the third song elves of the night sounds a little different. The AKG K44 sounds balanced. There is an insect yelling sound in the middle, especially like current noise. The performance is pale and there is no beauty; but Sennheiser CX180 and Apple EarPods can hear the sounds of the insects such as the summer crickets and insects. The squirrel H850 treats the relatively low frogs farther than the frogs. The Panasonic pig's nose and moto buds The details are lost more, and the barking of the dog is not very like ~~~~.
In short, for the student party, the landlord thinks that buying a headset is also a good headset, and the purchase price budget is the premise, to be able to buy. At the same time, we must accurately locate our own needs, and then we must select the brands and series that are better in the direction of individual needs. If there are conditions, it is best to audition in the physical store or look at the non-soft essay evaluation posts on the same series of products on the Internet. Online shopping should also try to choose a well-known B2C mall to avoid buying hot money to buy fakes.
Over and over, I'll talk about it this time. I hope everyone will pay more attention to my originality.
