According to the current facts, wired headsets, especially HiFi headsets, have already become the tears of the times just like HiFi speakers and home theaters. At present, the mainstream of the audio industry is Bluetooth headsets, smart speakers and car audio. Even the HiFi market is inferior to the professional sound reinforcement field, not to mention the embedded speakers of TVs, mobile phones and laptops. This is only the statistical results as of 2019 to open up this issue, we must first understand a concept. How did the former headphones beat the speakers and become the mainstream of the industry? Is it sound quality performance? Or more luxury attributes? Neither, but headphones are often much cheaper than speakers and speakers. Earphones become the key to mainstream, low price, convenient listening and a certain degree of privacy. To put it bluntly, it is cheap and convenient. And if there is a new form of product with higher convenience, then it is not surprising that the traditional form of headphones presents an overwhelming advantage. TWS headset is such a product form, and Apple’s strong market share also illustrates this problem with undisputed facts. HiFi headset itself is a pseudo concept. In other words, wired headsets have a large part of the hype factor. To put it bluntly, it is a bubble. For example, in the past few years, the market price of earphones has soared, and the price of tens of thousands or even tens of thousands of dollars has been increased at every turn. Accompanied by various overwhelming advertisements and sailors, describing how powerful these earphones are. The instigators of this series of chaos were Beats’ first sound recorders, Sennheiser HD800 and AKG K3003. Although Sennheiser HD800 and AKG K3003 themselves are not considered IQ tax, especially Sennheiser HD800’s performance is still remarkable. But the price bubble of earphones is brought up by these two earphones. This was mentioned in detail in my video a year ago. Now the bubble has burst and the tide has receded. It is not surprising that Sennheiser sold its consumer headset business for 200 million yuan. Will wired headsets die out? of course not. To answer this question, we still have to analyze the user group of the headset. I think it can be roughly divided into three parts: the pursuit of the ultimate audio experience, the pursuit of flexible and convenient use, the pursuit of a certain sound quality, but the budget and conditions are relatively limited. For these three types of people, there is no doubt that the second type is to collectively switch to TWS true wireless The headset is represented by the Bluetooth headset camp. So for the first type of users, based on the experience of many audiophiles I have contacted, many of them were “fudged” by the headset advertisements. They are not unable to play or have no conditions to play with speakers. Instead, they are simply confused by the hi-fi earphone advertisements, but when they have a certain experience and ability to judge the sound, they have also compared it with the speaker system. Once they realize the actual gap between the speaker and the earphone, they will give up the HiFi earphone. Switched to the embrace of HiFi speakers and home theater. In the past, I often saw such a message under my answer. And for the third group of people. This group of people may not have their own real estate, or they may still be in a university dormitory and have no independent space. But it can’t stand the impact of Bluetooth bit rate on audio transmission. So it will not rush to switch to the Bluetooth camp. The chip of the Bluetooth headset usually has 7-segment or 15-segment EQ, which is very convenient and flexible for the tuning of the headset, and it is easier to call up a good frequency response curve during the product development process. Although the traditional passive wired headset does not have a chip itself, there are currently many HiFi players and software that support EQ tuning. So for some players who use EQ and other tuning methods, the effect of Bluetooth headsets is largely inferior to wired headsets. In other words, wired earphones are the best solution when the speaker system cannot be used, and it is still improved compared to Bluetooth earphones. And Bluetooth headsets are almost all sealed designs, and wired headsets can choose an open design, which is more friendly to wear in summer. There is no doubt that this group of people will continue to buy wired headsets. In addition, there is also a group of people who belong to primitive earphone enthusiasts, and even some products tend to be fetish. Even if they have sufficient budget and venue, they will buy headphones. They tend to ignore the actual gap between speakers and headphones, thinking that headphones are the best sound quality products in the world, which is a bit similar to players of vinyl record players. Such players will continue to buy wired headsets no matter what. Finally, briefly review the two topics. The first is the sound performance of speakers and headphones. There is a qualitative difference between the low-frequency performance and spatial impression of traditional headphones and speakers, so this old-fashioned topic will not be repeated. Here is just another point of difference-the performance of the high-frequency part. It is almost impossible to find a headset that can precisely match the high-frequency response of a specific individual’s ear from the market, like a “blind cat hits a dead mouse”. And many earphones often have some peaks and valleys at high frequencies due to the acoustic principle itself. The speaker only needs to ensure that the high frequency response is flat. Therefore, the high frequency performance of headphones is often not as good as that of speakers. Another issue is the discussion about the sound quality between wired headsets and Bluetooth headsets. Although the sound quality problems caused by the wireless transmission protocol of Bluetooth headsets are usually inferior to wired transmission. But the tuning, or the frequency response curve, is not necessarily. Bluetooth headsets can be tuned electronically with the help of Bluetooth chips. Compared with traditional wired headsets with pure acoustic design, it has great convenience and is easier to tune out some curves. In fact, even now, there are still many “HiFi headsets” on the market that cannot meet the minimum performance requirements specified by the national standard and IEC, and there are many big brands and relatively expensive headsets. This chaos in the market is also one of the important reasons why wired headsets, especially HiFi headsets, are becoming self-destructive. You can deceive some people in one life, or you can deceive everyone in one life, but you cannot deceive everyone in one life. ——Abraham Lincoln In addition, wired headsets are still better than Bluetooth headsets in terms of delay, but not all wireless headsets. Because WiFi audio transmission can be lossless and low latency. It’s just that the power consumption and cost of the WiFi module are usually higher than that of Bluetooth, and it is relatively more used in wireless speakers.
