It’s really easy to refuse to play with headphones.

I didn't pay attention to it. I also had 7 or 8 years of playing with headphones. If I started from a fever, it was more than 5 years. Although it was not long, it was not short, and because I burned the headphones, I did not pay attention to it. This line, from a science optical man who has learned optics to a text editor who plays headphones... Life is really unexpected, why is it because of a fun hobby that has become a daily holding rice bowl? It’s completely impossible for YY to wear a white labyrinth in the laboratory to adjust the laser.

Ok, no longer idle, today is to share with you as an audiophile in recent years, especially as a professional audio editor's experience of playing games, to break some metaphysics, playing headphones is really very simple.

First, about the headset

Many people will find the earphones recommended by the author. After the new earphones are bought, many people will ask me a question, that is, "How do you use this music, what music do I use?", every time I hear this, I sigh "Hey you." XX", the machine will be the same as buying a new car. Do you have to buy a new car and run two rounds around the five rings to run in? (Sure someone does this... meet the needs of driving )

In my opinion, the "ç…² headset" is a natural thing to listen to. Generally, it will enter the state in about 100 hours. It is called "opening", but some diaphragms really have a 200. -500 hours, but some people said that 2000 hours later, the author laughed at that time, it is not called "opening", then "aging".

The downtime can be said to have been around for a long time. It is actually very simple to say. The new headphones are in the hand, everything is new. The speaker unit diaphragm has not undergone too many reciprocating vibrations, and there may be irregular texture inside. Or glued to the horse, so the vibration may lack some flexibility, the sound does not reach the ideal state, if after a period of play, the sound will naturally get better, but now many people make the "downtime" thing God's, I can't wait to take the opportunity to reinvent the feeling, I said don't pull it, it is a big flicker, because I have the work of evaluating headphones, so I often pick up the headphones, the method is extremely simple, that is, the songs are randomly played, every day. For 10 hours, the volume is the size I usually listen to. In about 10 days, the headphones are almost the same.

Therefore, it is very easy to understand the downtime. If you want to enjoy the most beautiful voice, you will put some music in it. If you don’t have the leisure, you will listen to it naturally. As for what time, what kind of music, or what frequency? , or pink noise, I asked a question, the diaphragm used in different headphones is different, so the performance is different, the rigidity is also different, how do you apply the same machine standard to so many different headphones? You are Is there research data from the laboratory?

The downtime is just to let the earphones enter their best state as soon as possible. If someone really looks at the angle of improving the sound quality, most of the result is "disappointment". In fact, slowly feel the change of the sound of the beloved headphones, it is also an appreciation!

Second, related to lossless music and mp3

Because of the rise of enthusiast groups, the demand for lossless music is growing, but the Chinese lack copyright awareness. You say that a group of music-loving people listen to pirated music every day, and domestic musicians have to rely on advertising and judges. Living, there is no good music in China... Is this a great irony?

Now some people, that can be regarded as listening to "lossless" music, feel that they have a taste, but you took his headphones and listened, I am going to go, the man with a horse pole... In the author It seems that, in fact, for the popular music, the amount of information about popular music is relatively small, and at present many of the music itself is a coincidence when recording, so even if it is not damaged, it is not much better, most of it. Relative to 320kbps MP3, it is really difficult to hear the difference.

Most of today's mobile phones have begun to support lossless formats, but the ability to play and display the lossless beauty is completely different. I used to play five pieces of different audio equipment to play the same song's lossless and MP3 music, and did a blind listening test. About 25 people, the two people really heard the difference and guessed it all, but one of them is in a half-malignant state. So, for most people, the 320kbps MP3 format is enough, currently In terms of the sound quality of mobile phones, it is better to change the high-quality headphones without damage. Therefore, the lossless horses are still only suitable for players with higher pursuits and higher-end equipment. (The author now uses the mobile phone to listen to 320kbps pop music every day. ......)

Third, "good push" and those parameters of the headset

"Is this earphones good to push?" This is a question that many new players who have been unfamiliar with the author have asked the author, but when they look at the headphones they buy, they are basically earplugs or portable headphones. I just want to say: "Now these things are done. The headset company is not a fool. Is it hard to push the headphones with the consumer?" So, if you choose a portable model, you will not have the problem of pushing the horse and sending enough sound pressure. That's definitely ok, of course, if you have better equipment, the sound will definitely improve, and those typical big headphones with a fever, if you are not a fan, don't think about it, because that really needs to consider "thrust" "The problem. (If you are going to have a fever, the best way is to look for an old burning consultation instead of looking at the evaluation article)

Since the thrust is mentioned, the parameters of the headphones have to be mentioned. In fact, many people have not noticed that there are some parameter identifications on the side or the back of the box of the earphone. The technical parameters are generally the impedance, sensitivity, frequency response, and maximum input. Power and the like, these parameters have a certain reference value is undeniable, but you want to know a headset through these parameters is a joke.

The impedance of a typical portable earphone is no more than 32 ohms (of course, the metamorphic earphone model has reached 60 ohms), and the sensitivity is generally above 100. Relatively speaking, sensitivity is more valuable than impedance, because this is you. Enter the sound pressure value that can be achieved with 1 milliwatt of power. The larger the number, the louder the sound, and this is the reference value of the earphone parameters for ordinary consumers. Remember, if you are using a mobile phone or a normal MP3 player, When buying headphones, the impedance should be well driven as long as it does not exceed 60 ohms and the sensitivity is not less than 100. (Of course, a good driver is only a prerequisite for good sound quality, but it is not necessary)
