After the rise of the smart phone industry, after years of fierce business battles, there are currently giant mobile phone manufacturers such as Apple, Huawei, OPPO, vivo, xiaomi, and Samsung in the market. In addition to the mobile phone industry, these giant manufacturers have also jointly promoted the development of other smart electronic equipment industries, the most obvious of which is the headphone industry.
Originally as an accessory for mobile phones, wired headphones were sold to consumers along with mobile phones, but with the advent of the TWS headset era, the wired headset market was gradually squeezed, and TWS headsets became the new favorite of the headphone industry. Not long after, Apple has announced the cancellation of the 3.5mm audio interface of the iPhone 7, and the purchase of mobile phones will no longer give away headphones, and many mobile phone manufacturers have followed.
From the perspective of the logic behind the cancellation of standard headphones by mobile phone manufacturers, responding to the concept of scientific and technological environmental protection, cost savings, and market development trends are the most important factors. According to I love audio network from the major mainstream mobile phone manufacturers of Tmall official flagship store learned that at present, Apple, Glory, Meizu, OnePlus, OPPO, realme, Samsung, Millet and other mobile phone manufacturers have implemented a full range of mobile phone products to cancel the standard headphones; while Huawei, vivo and other only a few mobile phones also have standard headphones, most of the mobile phone products have been cancelled to give headphones.
Headphone brand products in the market are becoming more and more abundant, consumer choices are also increasing, this track is becoming more and more crowded, and the competition is becoming more and more fierce. The cancellation of standard headphones by mobile phone manufacturers is a new opportunity for the headphone track. Because the market is vacant with standard headphones, any headphone brand can occupy it according to its own ability.
With the development and changes of the mobile phone industry and the headset industry, will mobile phone manufacturers resume standard headphones in the future? Or to achieve the full range of mobile phone products to cancel the standard headset? What new market opportunities will be brought by then? These are questions worth pondering.
In today's era, people are surrounded by a variety of electronic products, music is also an indispensable element in people's lives, with the development of audio technology, people have higher and higher requirements for sound quality, with excellent listening experience, has become the pursuit of many consumers.
