How hot is the smart headset? You will know when you read an old news.
In 2017, Apple introduced the second generation of wireless headset AirPods, which has built-in chips and plans to add functions such as Siri. Therefore, some media called it the "first smart headset."
Today, AirPods II products are still missing, and smart headphones have emerged as the most popular hardware devices after smart speakers. 
Recently, the well-known consulting company JFK Market Consulting (China) Co., Ltd. released the "China Smart Headphone Market Analysis" report, pointing out that the market will reach 500,000 in 2018, and smart headphones are expected to show large-scale growth. So, is the outbreak of smart headphones coming?
Cause of the outbreakBlack technology blessing and market demand create new enthusiasm
With the rapid advancement of human-computer interaction, speech recognition and other technologies, the wave of artificial intelligence has accelerated the upgrade speed of many traditional hardware devices, which has also detonated one smart product hotspot. In 2017, the hottest one is undoubtedly a smart speaker. There have been industry insiders jokingly, there are 100 smart speaker manufacturers in every square kilometer in Shenzhen.
Recently, another smart product has been highly anticipated by the industry because of its huge potential. It is a smart headset.
Since November 2017, a variety of smart headphones have appeared in the public eye. At the Tencent Global Partner Conference held in the month, Tencent exhibited an AI voice headset. This headset is built by Guangzhou Ailang Intelligent Technology Co., Ltd., and is equipped with Tencent's voice assistant.
A month later, another smart headset that also equipped with Tencent's voice assistant was released. The product was launched by the sports and headset brand 1MORE, mainly for the sports crowd.
By 2018, more smart headphones have sprung up. Internet startups, including door-to-door questions, and new headset brands such as FIIL have launched their own smart headsets, and major manufacturers have begun to deploy the field.
Industry insiders predict that relying on the development of voice interactive technology, smart headphones will break through the relatively single bottleneck of smart speaker application scenarios, or will become the next smart hardware.
With the iterative technology, the current smart earphone products are relatively mature, and are more perfect in terms of noise reduction, sound quality improvement, and near-field pickup. With the addition of AI technology, smart headphones have entered the fast lane of development.
"Different from Bluetooth headsets, in addition to traditional functions such as playing music and making calls, smart headsets are equipped with sensors and microchips." On May 8, communications industry expert Yang Yubin said in an interview with reporters, "Smart headsets will The human-computer interaction function is imported into the product to provide services such as life assistant, translation, search, etc., and the user does not need to pull out the mobile phone for other operations, thus completely liberating the hands."
Take Samsung's smart headset as an example. The headset has 4G memory and built-in fitness sensor, which can record data such as daily activities, exercise time and calories burned by users. Vendors also provide voice assistant services in this product. As the entrance to the smart home, the voice assistant can directly control the switch of the home appliance.
Not only that, social, medical, health management and other functions are also integrated into smart headphones.
Use experienceThere are signal instability, touch failure, and voyage difference.
"The biggest advantage of smart headphones is that it is easy to carry. It can be used at any time, fitness, walking, daily work, and the application scene is very rich." Zhang Wei (a pseudonym), the head of marketing of a smart hardware manufacturer in China, told reporters that the company is A smart headset product was just launched in early 2018.
Of course, smart headphones are not perfect. The outstanding problem is that some smart headset products still exist. Open a domestic e-commerce website, there are many negative evaluations under a certain hot-selling smart headset product. Many users report that the product has problems such as unstable connection of Bluetooth signal, malfunction of touch, poor endurance, and delay of playing video.
"Headphones are highly personalized products, and users have high requirements for sound quality. This is a remarkable feature of the earphone industry. Previously, there have been some factories that entered the field of headphones and encountered a wide range of incidents and bad reviews." On the 8th, Tsaiyu Industry Research Institute wearable device expert Cai Zhuo Shao said in an interview that if a company has limited hardware capabilities and poor seed user experience, the product will be quickly eliminated by the market.
In addition to sound quality, noise reduction and other traditional measures to measure the pros and cons of headphones, many products need to be improved in function. For example, when the Google wireless headset PixelBuds started the translation function, it still had to take out the mobile phone to assist the operation, and did not fully realize the idea of ​​liberating the hands. In this regard, Cai Zhuo Shao believes that if most of the voice interaction can be done directly on the mobile phone, then it is difficult for consumers to choose to use headphones to complete this operation.
The above report also pointed out that the price and consumer experience directly affect the future market trend of smart headphones. On a domestic e-commerce platform, the reporter compared several smart earphone products and found that the price of such products is currently between 500 yuan and 1,500 yuan. The built-in chip and micro sounding unit make the cost of the product much higher than that of ordinary bluetooth headphones. .
"For the earphone enthusiasts, the quality of the smart headphones can not be compared with the traditional products, and the novice users can buy a good entry-level headphones for only 200 yuan." Yang Yubin said that if you want consumers to spend more money to buy smart headphones , then it must be irreplaceable in function.
Post-potential predictionIt will take time to become a new generation of voice interaction portal
In the use scene, smart headphones are more abundant than smart speakers, and the positioning and application of the two have many overlaps. In the Internet of Things era of Internet of Things, some professionals predict that smart headphones will be connected to smart speakers and become the entrance to voice interaction.
There are different voices in this industry. Apple, Google, Samsung, go out to ask questions, Keda Xunfei, Wanmo and other large and small manufacturers have launched their own smart headset products, the old headset manufacturers Sennheiser, Bai Ya technology, love power are also eager to try, manufacturers use action Expressed his optimism about the development of smart headphones.
“The reason why smart speakers are so popular is because everyone thinks it is a better entrance. Because smart speakers are not mobile and can only be placed at home in most cases, the industry hopes to have a better product to pick up the entrance. Big banner.†Zhang Wei said that as a wearable device, the earphones are used more frequently and are more convenient to use, so they are given higher expectations.
On the other hand, the problem of the smart headset itself has also caused many analysts to take a wait-and-see attitude towards the market. It remains to be seen whether the product can successfully occupy the voice interaction portal.
"At present, smart headphones are still limited by factors such as size, weight and endurance. And smart headphones can't be completely independent now. Some functions need to be connected to smart phones, smart watches and other devices to achieve. There is a certain distance." Cai Zhuo Shao believes that in the short term, smart headphones still belong to product function upgrades, it can create new market space is limited, more will divide the original headset market share. But in the long run, the development of smart headphones depends on the advancement of mobile networks, voice interaction and other technologies. It is too early to talk about smart speakers.
