The Noise Reduction Effect Cost of 1000 Yuan Quality Can Be so Low?
Six months ago, if we said that.
Anyone who knows about the earphone industry will think we are funny.
But six months later, we dare to say this again.
That proves it! And it has become a fact!
If you have any doubts about the above seemingly "boastful" words, you can first listen to the noise reduction effect of the final finished earphone (by the way, guess how much the noise reduction effect is worth).
This is the time when the engineer tested, simulating the audio before and after noise reduction on the aircraft, and the overall noise reduction effect is very restored: (it is to wear it into the ear and turn on the noise reduction, so that we can send out the degree of "lying groove")
For this audio, its noise reduction effect is lower than that of Bose QC30, Sony wi-1000x and airplads pro.
But the gap is not big.
If we compare the thousand yuan noise reduction headphones produced by Huawei freebuses pro and Xiaomi ov mobile phone manufacturers, I dare say that their noise reduction effect is at the same level.
But what's the price of such headphone factory?
Although the noise reduction effect of headphones is indeed amazing, this does not mean that the R & D strength of the OEM we are looking for can be comparable with that of large manufacturers.
It has been 2 years since the airpods Pro was released in that amazing market.
In two years, the cost of noise reduction earphones has long been shared by countless large manufacturers.
This is a fact given by the market.
But when we hold the idea of "excellent noise reduction effect, but extremely high cost performance", we go to the OEM to raise demand.
Still 80% of the time is rejected.
There is no other reason: the price is too low and the cost is difficult to control.
In the whole process, there are not dozens or dozens of OEM companies to talk about. If you go into detail, you may not be able to finish it in three days and three nights (this is not the focus of our discussion)
The final cooperation is a foundry with more than ten years of experience in R & D and production of hearing aids and digital products.
For half a year, we have been running in, optimizing and reducing costs with the factory, constantly updating better noise reduction solutions, solving bugs, making molds and adjusting structure.
This is called zbliss active noise reduction headset. It's coming out.
In short, it is a cost-effective monster.
No brand, no star endorsement, really planed the marketing expenses and achieved the ultimate cost performance.
In terms of sound quality and call effect, we chose the general scheme of 100 yuan headphones, without stacking, but ensure the most basic level (don't worry, it's not too bad, at least the level of about 200 yuan on the market).
Then, we put all the costs on the active noise reduction Bluetooth chip! Realize the configuration of thousand yuan headphones!
If there are knowledgeable readers, just introduce the two chips we finally selected - Zhongke Lanxun (earphone activity price 199) and hengxuan bes2300 (earphone activity price 299)
Key points: these two earphones only have different built-in chips, and other configurations are the same.
The two chips are from listed companies. Needless to say, hengxuan technology is the leader of domestic Bluetooth chip enterprises.
Many are familiar brands, such as Samsung, Huawei, oppo, Xiaomi, JBL, rambler, Wanmo and so on.
Bes2300 is a chip configuration with a high position in the industry.
The earliest active noise reduction function was launched by it, earlier than apple and Qualcomm, and even one of the best results so far.
Huawei Xiaomi ov800 1399 yuan noise reduction headphones basically use this bes chip.
Bes2300 chip has a very high degree of adaptation. How high is it?
When the person in charge of the factory was forced to be helpless by us, he directly said to us:
"If this chip can't be put in, the others won't work."
I know you will have questions: since the bes2300 is good enough, why choose another branch? Because we really want to achieve the ultimate cost performance at the price below 300 yuan (a little idealized, but we just want to try).
Compared with bes2300, Zhongke's chip will be slightly inferior in functional stability and noise reduction effect.
However, if the number of non professional audio and non professional equipment detection catch up in the use experience, there is not much difference between the two.
If you are Xiaobai who has just entered the noise reduction Bluetooth headset, Zhongke's 199 is enough. (as for why the price is nearly 100 yuan lower, I can only tell you secretly, because Zhongke has only been on the market recently. If you think about it carefully, you will know that now is the best time to collect wool.)
Because it is directly delivered from the factory, compared with the brand earphones we have recommended before, such as fiil, magic, pamet, etc., its sound quality adjustment and call effect still have room for improvement (after all, every penny is worth every penny), but it is also above the standard.
Its biggest feature is the noise reduction effect.
We spent all our costs on the active noise reduction chip, creating such a cost-effective monster.
If you pursue a balanced headset in all aspects, it will always make you feel dissatisfied, but if you need a noise reduction headset that makes the whole world quiet, it is undoubtedly worth it.
As for the earphone shell, I'm not afraid of being laughed at. How hard I work on the chip is how "stingy" I am.
The word "stingy" here does not mean cutting corners.
We didn't come up with a design scheme, but when we asked to control the cost, almost all of them were rejected by the factory.
Design, material selection, software and hardware running in Without any experience, he finally chose to compromise. It applies the more mature molds in the market.
If you know about real wireless noise reduction headphones, you will know how cost-effective this headphone is. For the same brand with this mold, real wireless noise reduction headphones sell more expensive than airplads.
After we got the sample, it was not measured according to the standard. The weight of one ear was about 4.1G, which was very light. The wearing experience was not inferior to that of airplads.
It is not only light, but also very comfortable to wear. It has no foreign body feeling and is very close to the ear. The package also presents three sets of ear caps s, m and l, which can be changed into the most comfortable one according to the size of your ears.
Vigorous exercise can't be thrown away. You can wear it for fitness and running at ordinary times. (although you have seen this test many times, I insisted on doing it once in order to prove it effectively)
01 supports noise reduction and transparent mode, with excellent radio effect
Both headphones support noise reduction and transparency modes
Although the two chips are different, the noise reduction depth is 25dB.
In the noise reduction mode, it can greatly reduce the environmental noise and enjoy the immersion of music in the busy market and cabin.
In order to show you the noise reduction effect, Xiaobian has recorded it for a long time, but due to equipment problems, it has been unable to perfectly restore its amazing effect.
When the engineers tested before, they simulated the audio before and after noise reduction on the aircraft, which is very restored as a whole. You can feel it and have a look:
Bridge Mode
It must have a transparent mode, which is what we, as users, insist on from the beginning to the end.
In the noise reduction mode, you can't hear the ambient sound outdoors, and it's very dangerous to run outdoors and cross the road.
However, in the transparent mode, the external ambient sound will be received. There is no need to worry about not hearing the traffic flow and horn sound.
Another point is that we think it is very important.
Even in the transparent mode, this headset can accurately identify environmental noise, wind noise and human voice. You can talk clearly wherever you are. You don't have to shout like a Han PI when talking. The other party can hear you, whether it's on the subway or in a windy day.

Stable transmission, lower power consumption and longer endurance
Regarding the low latency problem of Bluetooth headset, which was once criticized, it has been popularized when we recommended Bluetooth headset.
Once upon a time, when domestic headphones were still using Bluetooth 4.2, Sony and airpods took the lead in the real wireless market with Bluetooth 5.0 technology.
But now, most Bluetooth headsets on the market, whether domestic or overseas brands, have almost applied Bluetooth 5.0 technology.
Although both headphones use Bluetooth 5.0 technology, we don't want to take too much credit for this. (even secretly think that Bluetooth 5.0 should be popularized for headphones at this price)
Bluetooth 5.0 has more stable transmission, lower power consumption, faster connection, lower delay and stronger compatibility, which can make you feel the pleasure of second connection.
Colleagues played several games with it, and the sound effect was not delayed.
Coupled with the good noise reduction effect of the headset itself, it definitely gives you a perfect immersive game experience.
In addition to the above, the endurance of noise reduction headphones is also a point of great concern to many people.
After all, "you have to charge after wearing it for a while, and you have to charge after a while", which really affects your mood.
The chips used in the two earphones have relatively low power consumption. When a single earphone is fully charged, it can be used for about 3 hours, and the charging box can be charged 6 times.
The endurance can't be said to be particularly excellent, but it's also enough for daily use.
The headset charging bin supports wireless charging, which is also a breakthrough point of this headset. It doesn't matter if you forget to wear a data cable when you go out.
Waterproof and sweat proof, reaching IPX 4 level, it is a must for iron rolling.
Of course, there will be no problem if it rains accidentally.
The packaging adopts geek style, and there is no sense of cheapness in appearance and workmanship.
It's about the same size as a lipstick in a girl's bag. It's small and exquisite, which adds a layer of fashion aperture to the whole person.
Men who don't like backpacks can carry them in their pockets at ordinary times, which doesn't hinder them at all.
Starting to want to make such a real wireless noise reduction headset really stems from our "whim"
But the final decision to do it is actually due to the enduring discussion: "what is a good Bluetooth noise reduction headset recommendation below 500 yuan / 300 yuan / 200 yuan?"
The reason for these discussions may be that inexperienced users who are afraid of being cheated "want to buy the best headphones at the most appropriate price".
We are not the main manufacturer of this headset.
In the whole process, we are more like a supervisor and experiencer.
From the perspective of users, experience and suggest, and finally present the good active noise reduction headphones below 300 yuan to you.
Although the world is noisy, as long as you wear it, you can go to another world.
A quiet world where you can imagine freely.
