A team of friends developed a headset by themselves and asked me to help them write an evaluation report (I had never written one before), so I collected information and started testing. I have definitely learned something along the way, and it also gives some reference to friends who are not particularly keen on music but are pursuing it a little bit. You can use some of the following songs to test your headphones. The tests mainly focus on distortion, detail, three-dimensionality, and three-tone testing.

1. Simply test the distortion, play music, and adjust the volume to the maximum (don’t test newly purchased headphones. New headphones need to be burned in. Too loud will damage the headphones). There is basically no noise or noise when testing the headphones. Discordant tone. Overall: ☆☆☆☆☆ (the highest five stars, the same below)

2. Test the three-dimensional effect of headphones; the songs "Aerozone from Jean Jarre's Aero album" and "Carmen Overture"

< p>Use this song to measure and test the three-dimensional effect of the headphones from all angles.

"Aerozone"

(1) At the beginning of the song, you can hear the subway moving. You can clearly hear the subway sounds coming from the left and right sides from far to near and then to far, 1 minute 15 There was the sound of an intercom every second, and there was an agitation sound from time to time in the middle. Within seconds starting from 25 seconds, I could hear the sound of electronic music moving from left to right, with obvious changes in position.

(2) Starting at 1 minute and 15 seconds, the focus of the test is that you can hear a sound constantly surrounding the entire environment. It feels like you are walking around like a clock. If there is no This feeling is obvious, and the headphones have been changed. At 1 minute and 33 seconds, you start to hear sounds like motorcycles or airplanes or other sounds driving from left to right (or right to left) again and again.

(3) Starting at 2 minutes and 31 seconds, there are rapid Thrumming electronic music is front and center. At 3 minutes and 24 seconds, there is an obvious sound that is twinkling like a star, but there is a slight change in position. It is estimated that headphones of inferior quality will not be able to hear the change. During this process, another sound surrounds the sound that appears for 1 minute and 15 seconds.

(4) Starting at 4 minutes, behind the main melody, the sound of a train seems to be heard far away. At 4 minutes and 17 seconds, the faint voice of children is heard in the distance. At 4 minutes and 22 seconds After a few seconds, the sound fell silent, and finally I could hear the sound of birds outside the window, and the very real sound of a person turning the pages of a book in front of me.

"Carmen Overture"

I will not analyze this in detail. In it, various musical instruments can be expressed in different levels at different points (like a plane, far, near, left and right). Basically there is a clear distinction.

Overall: ☆☆☆☆

3. Test the vocal detail effect: "One I Love" and "Osaka Castle Girl" Vivi version

"The Girl of Dasaka Castle"

This test is relatively simple, because it is completely matched with a cappella singing. When the multi-singing starts, the headphones can basically distinguish how many voices are clearly distinguished. At most, it should be There are four. If you can’t hear it or it’s difficult to identify, it’s because your headphones are not good enough, or you need to practice listening to it more often.

"One I Love"

This song is also sung a cappella by the human voice. From the beginning to 1 minute and 15 seconds, the details of the human voice are well displayed, including swallowing. Drooling and ventilation, sibilance. Listening to the test headphones, the sound of swallowing is obvious at 11 and 12 seconds, there is ventilation at 25, 31, 38, 50, 57, 1 minute and 8 seconds, and there is a weak swallowing sound at 50 seconds. If you don't hear it, the resolution of the headphones is not enough. Later, after the accompaniment started, there were many sounds of swallowing, so listen to it yourself.

Overall: ☆☆☆☆

4. Test high and low bass

Bass: "Drum Poetry", "Grandma's Penghu Bay-Zhao Peng", " "Ferry"

"Drum Poetry"

This is a pure traditional Chinese drumming music. Most of the drum sounds in the whole song are short and powerful. It can be used to test the bass of headphones. Of course, Feel the strength. The depth of the drum sound is quite good, and you can feel the buzzing sound of the drum after each hit. The fast-hitting drum sound is short and powerful, and each beat is stopped with one strike, so you can feel the strength of the blow and will not be weak. If your headphones feel that the sound is not powerful or full enough, that is the performance of the bass of the headphones. If it is not good, or the source power is not enough, you can use an equalizer to increase the bass. At the end, a bunch of drums appear at the same time, and you can hear that some of them are separated, but the separation is not particularly obvious. Overall, the performance of this song is quite shocking and tense. The reason is that the headphones are specially designed to process the bass, and the bass effect should be the best.

"Ferry"

The first three drum sounds can effectively test the expressiveness of the bass. The sound is clearly layered and has a strong sense of shock. The bass is fully expressed here. . Paired with Tsai Chin's warm and soft voice, her singing skills are great!

"Grandma's Penghu Bay - Zhao Peng"

This song can be called a bass bomber, especially the deep vocals in the climax coupled with the powerful hits. Beating the heart. Completely changed my impression of this song.

Overall: ☆☆☆☆

Treble: "I Just Like You"

The vocals are a bit unbearable when the vocals are high or high db, which is a bit irritating The eardrum can be adjusted by lowering the high frequencies on the EQ. After adjustment, the vocals are gentle and delicate, as if the voice is singing nearby.

Overall: ☆☆☆

The last song to test the overall effect of the headphones (I directly copied a standard online to test): "Lucia di lammermoor" - Vitas

This song has a lot of accompaniment, details, and treble, and is used to test the details of the headphones, the three-dimensional sense, and the treble. The first wave:

A fast melody of the violin starts at 1 second and is accompanied by the beating of heavy drums, and the piccolo begins, and at 10 seconds the low drum begins to beat quickly. (You can hear it)

The male idol starts singing in 13 seconds, the sound field is wide, you feel like you are under the stage of the opera house. The male god's voice was penetrating and powerful, not like screaming at the top of his lungs when he had a bad cold. The soundtrack and male vocals are separated and distant. (There is a certain distance between them, but I don’t feel that it is open)

There is obvious vibrato in the 40-second male voice. The rhythm of Douyin is not sloppy. (Listen)

There are two separate pieces of music at 52 seconds, which are like a disconnect. The sense of disconnection is strong. (Listen out)

Test the mid- and high-frequency of the headphones. If the sound is not broken, it means that the mid-frequency separation of the headphones has passed. (Not broken).

Second wave:

The music stopped at 1 minute and 30 seconds, and a sound similar to a motorcycle engine starting appeared on the scene. (This is very obvious)

After the fourth engine start at 1 minute and 37 seconds, the music began to erupt. Violins, cellos, piccolos, etc. played from 9 to 11 o'clock. The male voice was in the center of the stage, and there were people in front of them. A rapidly struck plate-like instrument. (Can feel the positioning)

At 2 minutes and 21 seconds, I can hear the R&B-like dubbing of other voices alone. (You need to listen carefully)

The climax of the male voice at 2 minutes and 25 seconds, the voice here is high and bright, and it is soul-stirring. With applause. Bad headphones here sound like mosquitoes. (You can’t feel the sound of mosquitoes, but you can hear the applause)

Many headphones that are good at playing high frequencies will be exposed in this wave. The sound will break. It's not very good if the male voice sounds like it's very difficult to hold up the sound.

The third wave:

At 2 minutes and 29 seconds, the male voice increases from small to loud, and various instruments gradually overshadow the male voice, but the male voice can still be distinguished separately. The scene is not chaotic. ()

The applause and cheers after the end were loud and clear.

If your headphones do not perform as well as Lou Lou, but they still sound great, there is no need to blindly update the equipment, because everyone has a different understanding of shock. .

Overall performance: ☆☆☆☆

Well, that’s it for the review. The above guide can be used to test your own headphones. If you don’t like it, don’t criticize it. If you need to buy it, please contact yourself. , Tel: 18826412774.

Just say it was introduced by Dong! Price: 99 yuan! Personally, I think it should be similar to the headphones on the market that cost more than 300-500 yuan!
