Folks, comrades, old and young men and beautiful girls, good evening everyone, I am the favorite hitman Yoyo sauce of the boss of Renmeixinshan. The Double Eleven Singles Day has just passed, and Xiao Twelve came quietly again. In order to celebrate the happy second time of handsome men and beautiful women, I will give you a split haha.
Not just after the beginning of the month, there are a few sisters who have paid back the flowers, eating instant noodles and chewing on their fingers. They come to me for a Christmas guide. Hey, hey, you can borrow it again, nothing to say. Yes, in order for our company’s northwest wind to continue its big sales next month, my sister must make arrangements.
Of course, Double Twelve has just passed, and I think you have already bought almost the things you just needed. Not to mention a lot. Today I will just talk about a Bluetooth headset that I just pulled. Since Apple mobile phones announced the cancellation of the 3.5mm mobile phone audio interface, Bluetooth headsets have quickly become one of the most popular electronic products. In just a few years, they have developed from the original heavy ears and single varieties to the current light and fashionable, full of flowers. Taking advantage of this Christmas hand chop festival, as a cold and beautiful girl who likes to live in her own world, this girl also started the idea of a Bluetooth headset. After five days of obsessive-compulsive disorder research from beginning to end, she finally I have selected my favorite one, and now I will tell you in detail about my purchase experience.
1. General outline
The old rules, let me talk about the parents of Bluetooth headsets.
The emergence of Bluetooth headsets is mainly due to the successful development and popularization of Bluetooth wireless transmission technology. In 1994, Ericsson developed Bluetooth technology in order to eliminate the traditional serial data line (RS-232 interface) and provide better information transmission methods for its products. The term “Bluetooth” of Bluetooth is taken from a very promising one in Northern Europe in the Middle Ages. The nickname of the king. It mainly shows that this is a technological innovation of great significance. Bluetooth is a short-distance wireless connection technology standard. The essential content is to establish a common radio air interface and open standard for its control software.
Initially, Bluetooth was mainly for all kinds of data and voice equipment in the network, such as PCs, laptops, printers, fax machines, digital cameras, mobile phones, headsets, home appliances, etc., using wireless microwave methods to connect them into a piconet. Multiple piconets can also be interconnected, so that communication between various devices can be realized conveniently and quickly.
The earliest Bluetooth architecture
With the gradual maturity of Bluetooth technology, the first Bluetooth headset was developed in 2000, using Bluetooth 1.0 version, which can only allow voice to be transmitted in mono. Although it can meet the needs of calls, it cannot be used Listen to music. In addition, the first Bluetooth headset is limited to headsets, and its purpose is to not disturb others when watching movies in the living room. With the rapid development of Bluetooth technology in the following ten years, stereo Bluetooth headsets, left and right earbud Bluetooth headsets and true wireless headsets in recent years have appeared one after another, and Bluetooth headsets have truly entered thousands of households.
Closer to home, in the face of the increasingly wide variety of branded Bluetooth headsets on the market, how to choose one of your favorites has really stumped a large number of patients with selection difficulties. Then here I will take out the purchase experience this time and briefly talk about it. Please send money to me if it is not good. According to my understanding, the most important aspects of Bluetooth headsets are five points, which are good-looking, good voice quality for calls, strong noise reduction, and long battery life. Finally, it is cost-effective. After all, the wallet is limited. The following is a comparative analysis of FunBuds, oppo W51, Sony XM3, and Huawei freebuds pro, which are popular in the market:
The earphones are worn on the ears every day. For our little brothers and sisters who are brewing, the appearance must be the first. Not to mention the handsome looks like Panan, then the beautiful Shen Yu Luo Yan. The little ones are on the picture, and compare:
FunBuds oppo W51 XM3 freebuds pro
The comparison is obvious. The design of FunBuds Walker is biased towards young people. The style is lively and fashionable, and the color scheme is simple and generous. Especially the pink model has captured the heart of a large group of brewing ladies, and the other three models have to be basic It is black and white, with a serious business style, suitable for cool little brothers.
Three, call function
For users like me who usually have a lot of calls, they have been worried about the call quality of the headset I bought this time. After all, it has a huge psychological shadow on my previous 66.6 Bluetooth headset. I thought I was driving the hands-free, and the voice was low and it was not clear. In order to compare the authenticity, I deliberately got the real machine trials of these products from the circle of friends. I have to say that it is different from the 66.6. Especially Huawei’s freebuds pro. After all, you get what you pay for. Its voice clarity and recognition are higher than the other three, mainly its unique 3 microphone + bone voiceprint fusion call noise reduction technology, which greatly improves Voice clarity makes “voice dialogue as clear as face-to-face chat.” Followed by FunBuds Walker, whose call quality is also a big surprise to me. Even if both parties are in a noisy supermarket and other environments, the voice is still relatively clear, and it automatically reduces people through its unique dual microphones. Voice, effectively remove environmental noise and retain clean vocal information, which is especially suitable for people with more call needs.
Of course, the call quality of the other two models is also very good, but it is still slightly inferior to the above two models.
Four, noise reduction function
The noise reduction function refers to the processing of the noise of the Bluetooth headset. The ordinary Bluetooth headsets we usually use are always affected by the external noise, which causes the quality of the voice and sound quality to be affected when we talk or listen to music. We usually do Just turn up the volume to deal with the noise. At this stage, noise reduction technologies on the market are mainly divided into active noise reduction and passive noise reduction.
Active noise reduction: The ambient noise is collected by the noise reduction microphone, and then processed by the Active Noise Cancellation (ANC) chip to generate a reverse 180-degree phase sound wave, which is transmitted to the human ear canal through the earphone speaker, and the noise is generated The phase difference is 180 degrees to cancel the environmental noise that human ears should hear, so as to achieve the purpose of noise reduction. Schematic diagram of active noise reduction principle The typical indoor environment noise spectrum is shown in the figure below.

Passive noise reduction: mainly by surrounding the ears to form a closed space, or using sound insulation materials such as silicone earplugs to block external noise. The most common earphones designed with in-ear earplugs and large earmuffs can be classified as passive noise reduction headphones.
To put it simply, it is one that uses sound wave technology to cancel the noise, and the other uses physical equipment to isolate or absorb noise. At this stage, the mid-to-high-end Bluetooth headsets on the market all use active noise reduction technology. Of course, a reasonably designed active noise reduction headset must be It also has a good passive noise reduction capability (sound insulation), and a two-pronged approach is ultimately better.
Comparing the four headphones, they all use active noise reduction technology to effectively reduce the impact of noise on sound reception.In the actual audition process, Huawei’s freebuds pro also performed the best, and received less noise from the external environment. After all, it claims to be the largest of 40dB. The noise reduction effect can be achieved. And the small fan FunBuds is not to be outdone. Its core hybrid active noise reduction technology effectively reduces the noise to the minimum, which has completed my good wish of being a quiet and beautiful woman in the crowd. The performance of oppo W51 and XM3 is roughly Equivalent, the noise reduction effect is slightly inferior to the above two.
Five, battery life
In terms of battery life, FunBuds is unique in terms of battery life. The full battery life is about 9h (headphones) + 23h (charging compartment) when the noise reduction is turned off, and the follow-up flight is about 7h (headphones) + 18h (charging compartment). The actual measurement completely satisfies my listening to songs for a whole day. The needs of heavy music lovers. The remaining three models have not been tried one by one due to time reasons.According to the official website data, oppo W51 has a noise-off endurance of 24h (including charging box), and the other two models are also above 30h (including charging box). There is not much difference here. .
Six, cost performance
In other respects, FunBuds may be absolutely unique. I won’t talk about the activities at the double eleven. If you look at the double twelfth event, the price is 319 yuan (USD $46) , compared with the other oppo W51-499 yuan (USD $7) , XM3- 1299 yuan (USD $186) , freebuds pro-1099 yuan (USD $157) , the price can be described as lower than the sky, especially in the actual evaluation, its noise reduction, battery life, call quality and sound quality are no different from the other models, or even exceed some aspects, plus Its young and fashionable appearance design is also well received by the public, and it is incredibly fragrant.
Comprehensively comparing the above points, considering my low budget level, I decided to start FunBuds Edifier. It has been more than half a month so far. I have to say that it is really fragrant.
Not much nonsense, the picture above~~~
Send it wrong haha, try again~~~
Look at my silky hair and beautiful face, ah no, look at my greasy little earphones, pink and tender appearance, delicate and beautiful shape, all means that the person wearing her must be a beautiful woman, cough cough, be serious, We are a rigorous planting paste.
In actual use, in addition to the good performance of the above points, the low-latency performance of FunBuds is also quite good.Under normal circumstances, listening to songs and watching videos basically does not feel the delay, and the game mode is as low as 80ms. All of his hand injuries have been cured a little bit. Of course, there are many other humanized smart designs such as tapping to operate the next song/pause/play/answer/hang up/switch noise reduction/game mode switch, smart master-slave switch, arbitrary use of left and right ears, etc. A must-have for home travel, work and leisure.
