Yes, headphones are originally a mysterious thing, and cooking them is even more mysterious. It is said that 100 yuan can be boiled into 500 yuan, and 500 yuan can be boiled into 1,000 yuan. If you know how to cook, you can also boil 100 yuan into something. It costs 1,000 yuan..

| hello~ I am your der (deer), a nerd who loves digital, likes to talk about current affairs, and digs out cost-effective things. Der friends, please give me a follow!

der I have forgotten how long it has been since I heard the words " for headphones ".

Yes, headphones are a mysterious thing, and cooking headphones is even more mysterious. It is said that 100 yuan can be boiled into 500 yuan, and 500 yuan can be boiled into 1,000 yuan. If you know how to cook, you can also boil 100 yuan into something. It costs 1,000 pieces to cook... so much so that there are various " and cooking tutorials" circulating on the Internet.

However, I found that most people use wired headphones for listening to headphones.

But recently, a friend tried to burn in his wireless earphones. Although it was the first time I saw it... But after calming down and thinking about it carefully, I felt that there was nothing wrong with it - after all, wired earphones can be burned in to improve the sound quality. , wouldn’t wireless headphones also work? ! Of course, some people think that wireless headphones have no sound quality at all and are just for loneliness.

So today der will talk to you: Is it necessary to burn out wireless headphones?

Principles and changes of burning in headphones

First of all, we know that what burns in earphones is the diaphragm of the sound-producing unit of the earphones.

To put it in a scientific way, the unit diaphragm of our new headphones has not been used yet, so it is relatively hard or brittle, and the sound it emits is naturally not in its best condition.

Although normal use can gradually bring the unit diaphragm to its optimal state, in order to save time and effort, specific sounds such as white noise are used to quickly reach the optimal state of the unit diaphragm through dozens or hundreds of hours of playback.

Since every time our headphones are cooked for a period of time, the unit diaphragm will undergo some subtle changes, then is the sound really much better?

This is not necessarily the case! We know that the sound produced by headphones is inseparable from impedance, low, medium and high frequencies. When new headphones are purchased, the sound produced is still the manufacturer's own tuning standard.

So someone did experiments and made statistics, and found that according to the length of use of the headphones, the impedance, low, medium, and high frequencies of the headphones also gradually changed. That is, after the power was turned on, the sound of the headphones was compared to the original adjustment by the manufacturer. The audio versions do differ.

In fact, this is not difficult to understand. Just like when we wear new shoes, they are very hard when they are first bought. After wearing them for a few times, they will become softer and more comfortable, and the feeling will be completely different.

In addition to daily use or listening to songs, there are also some tutorials on how to turn on the phone using white noise, pink noise and other "quick pass" methods, which greatly expands the song range of the earphones and allows you to listen to songs of various styles with ease, thus becoming a "universal oil". ".

General White noise Everyone has heard it, like the ticking of rain, the crashing of waves on the beach, or the rustling of leaves in the woods. Although it sounds very empty, its energy distribution in each frequency band is very even. Using it to burn in the unit can make the unit diaphragm adapt to the sounds of different channels more quickly, thus adapting to various styles of songs.

Everyone has heard of pink noise, which is like the rustle of an empty radio channel, but it is not recommended that you listen to it all the time! !

Of course, the above are just data. After all, whether it sounds good or not depends on personal subjective factors. Otherwise, how can we say that the sound quality is very metaphysical?

True wireless earphones burn-in

We know that burn-in can improve the impedance and low, medium and high frequencies of the earphones, thereby changing the sound.

However, the DAC chips built into some wired headphones are relatively large, the wires are average, and the impedance can be very high, requiring high power from an external power supply to drive them.

Due to the limited size, true wireless earphones do not have an external power supply from wires. In order to take into account battery life, the power is not too high, the DAC chip is not very large, and the hardware is far inferior to wired earphones.

Therefore, true wireless earphones have low impedance and relatively small thrust. If you listen to some rich music, they will appear thin and ineffective. This is why many people always say that true wireless earphones do not talk about sound quality.

Since impedance is unavoidable, is it possible to burn in the machine to improve the low, medium and high frequencies of true wireless headphones?

The answer is yes, but the sound quality of true wireless headphones is too limited by the hardware chip, so even if the low, medium and high frequency sounds are improved, the effect will be limited.

Fortunately, no matter how good the hardware chip used in true wireless earphones is, the improvement in sound quality will only be slightly better, but what remains unchanged is that the unit diaphragm of the true wireless earphones is the same as that of wired earphones, and the unit diaphragm can be appropriately " "Cook" to the best condition.

You must know that the price difference of true wireless earphones is 10 times that you can touch it on your butt after just using it for a while. The price/performance ratio is instantly higher, isn’t it?

In addition, der feels that true wireless earphones are really not necessary to be the same as wired earphones, so I deliberately put them on hold for hundreds of hours.

Because true wireless earphones have built-in batteries, leaving them on for a long time can easily lead to battery loss and poor battery life. Moreover, most true wireless earphones are now equipped with a take-off and pause function, so you have to take more tedious steps to turn them off.

Finally, der feels that it is not necessary to turn off the true wireless earphones specially. Just listen more frequently and wait for a long time to turn off the phone. But don't keep looping "The Crossing" and " Hotel California ". After all, no matter how much you cook, you can't tell who is knocking on the windows or playing the strings. Is the third person on the left in Hotel California drinking water? .
