Before the article began, the machine brother would like to ask everyone here - how much are the headphones you use now?
Five hundred and one thousand? Or more than two thousand, three thousand dollars?
The eighth brother couldn't stand it at this time: Well, I want to say, ten thousand yuan or less is to listen to a ring...
If you can't talk, don't talk well - cough, the eighth brother who talks nonsense has been dragged to the little black room by the machine brother and cleaned up fiercely. Let's move on.~
According to the eighth law of the machine brother, the quality and price of items are proportional.
It's not hard to conclude: the more expensive the headphones, the better it is.
So, this headset is good, where is it good?
Even though the materials used for workmanship are all different between different headphones, in the final analysis, to measure the quality of headphones, we still have to look at the sound quality.
Brother Ji feels that sound quality judgment involves the professional music field, you and I are just ordinary people, or do not do evaluation as well.
So what kind of people are qualified to evaluate?
Ji Ge recently saw such a video, by 15 central Chinese Orchestra players, on 3 different price points of wired and wireless headphones, a blind evaluation of sound quality.
Prices are: 50 yuan, 1000 yuan and 5000 yuan.
The answer is not surprising, the lowest grade wired headphones do not have a vote. The most expensive 5,000 yuan wired HiFi headset was 8 votes.
In addition, these 7 votes, all fell on the price of 1000 yuan, OPPO Enco X2 this wireless headset.
Some performers even said that they were difficult to choose when voting, and praised its sound quality performance.
To be honest, when the machine brother saw this part, I was confused.
But after listening to the head wheat part, the machine brother also understood why the performers were so entangled, because... I didn't tell the difference between the machine brothers.
Friends may also wish to come to the audition and guess, and the brother will first put the results in the comment area.
But the brother is still difficult to flat, OPPO this headset actually committed the following offense, directly and wired Hi-Fi headphones dry, it is really outrageous...
As a machine party, The machine brother is extremely scientific - from a physical point of view, the high sound quality on the wireless headphones is actually challenging the physical limits.
Hi-Fi headphones, also known as hi-fi headphones. With high fidelity, you will pursue lossless audio, which can store more musical details than ordinary audio. As for the intuitive feeling, what is it.
Brother Ji held up a chestnut:
For example, when listening to the same piece of performance. Ordinary headphones may only be able to hear the instruments contained in general, but Hi-Fi headphones can not only hear more specific details, but also hear the location of the instrument.
Simply put, it is the "immersive" listening to songs in the middle of the situation.
But this also raises the question: the more details the audio contains, doesn't that mean that the volume of the transmitted audio also becomes larger?
We can open NetEase Cloud or QQ Music to see the same song, the volume under different sound quality.
However, this is not a problem on wired headphones. Precisely because oppo Enco X2 is a wireless headset that goes for Bluetooth transmission. Bluetooth transmission has bandwidth.
Bandwidth, like the lanes of a highway, audio information is the cars on the road. Higher resolution audio also means more cars on the road.
But the lane is fixed, and when there are too many cars, it is natural to be stuck in traffic and can't move.
Even Apple, which has always been a good face, said in the previous interview about the sound quality of AirPods that it was limited by the physical limitation of Bluetooth bandwidth, resulting in a bottleneck in sound quality.
Therefore, how to take advantage of the physical god Newton's snooze kung fu to "bypass" this restriction has become a common difficulty in how wireless headphones can improve sound quality.
How to "bypass"?
If you think about it, when we usually send large files, if we encounter a size limit like WeChat, what will we do - yes, it is "compression".
It's just that in the field of headphones, a similar operation is called "encoding". The corresponding decompression is called "decoding".
But in the process of encoding and decoding, the file itself will be more or less lost, and the so-called "lossless" we listen to is actually "lossy" after transmission.
Therefore, this requires each family to make a trade-off on the degree of coding.
Like this time, it is said that OPPO Enco X2 uses LHDC 4.0 coding technology, under which the transmission bit rate has been greatly improved.
Not only that, but the transmission rate is also 3 times higher than the traditional one.
The problem was solved, and OPPO Enco X2 took a Hi-Res small gold label.
But that's not enough, the headphone hardware itself is also important. It can't be said that there is no hardness in speed alone, right?
The so-called phrase "although the sparrow is small and complete" is not fully applicable in the field of phonology.
If nothing else, as far as the volume of wireless headphones is concerned, stuffing a peanut is not enough. But inside there's a stuffed decoder, battery, microphone... Oh yes, but also the horn.
In addition to the need to pass the very harsh stacking process, so that the timbre changes greatly, the volume of the compression unit, but also must always follow the basic physical rules.
For example, the "sound field" is what we call the "sense of space" in our words.
This is really a "flaw" in wireless headphones. At this time, I still have to learn from the high-end audio.
This is the acoustic system developed by OPPO and Dynaudio , SuperDBEE's second-generation coaxial dual-unit.
In simple terms, it is to "tie" two units on the same axis to ensure that the distance between the two is unchanged. At the same time, the two units are not on a flat surface, but deliberately placed one after the other.
In the macro world, this subtle difference between before and after brings about the so-called sense of sound field distance.
The brother also went to see the recent audition, which also has an ultra-thin bass diaphragm of only 0.0095mm in this unit, and debuted many new highlights such as Sandwich four magnetic structures.
Although these are all Chinese characters, none of the eight brothers can understand them. However, the eighth brother did find a blind spot -
And OPPO cooperation dynaudio is not simple, people are professional to do high-end audio, machine brother I casually searched, the price is very touching...
OPPO this wave, it is true that it is not too "thick".
In short, the machine brother is quite looking forward to the performance of OPPO Enco X2. Although I have not had a fever for many years, I have now worn wireless headphones to get by.
I remember a long time ago, some so-called big bulls, with the Bluetooth transmission rate on paper, directly and unilaterally announced the "death penalty" of wireless headphones and Hi-Fi.
We can only stubbornly wear ordinary headphones and listen to the so-called "lossless sound quality" in the App. It is also at the bottom of the "wireless headphones are shit", such a discrimination chain.
If there is such a model, it is very likely to refresh the wireless headphone sound quality ceiling, narrow the distance of wired Hi-Fi headphones products appear, brother I am willing to complain again.
