Some friends are still using mobile phones before, and they are too stuck for five or six years to think about changing to a new one, but a look at the mobile phones in the market, the configuration has been improved and all kinds of changes are very big, and it really doesn't take a little time to understand, after so many years of development, the mobile phone industry has already been turned upside down, during which the mobile phone has brought a lot of new features and new designs, and at the same time, a lot of old functions and old designs have been eliminated, among which the headphone jack has been eliminated early.
Before we will have multiple interfaces at the bottom of the mobile phone, in addition to the charging port, there will be a headphone jack, which can be plugged into wired headphones to listen to songs, but now if you want to plug in the headphone jack, you need to use the converter to plug in the charging interface, many new mobile phones only have this interface, and the previous 3.5mm headphone jack is basically canceled, only a small number of thousand-yuan machines or hundred-yuan machines will have headphone jacks, those mid-range or high-end machines, basically all use USB interfaces, so why will this socket be canceled? In fact, the reason is very real, and you will understand it after reading the following 3 points.
First of all, it is out of consideration for waterproofness and thin design, so the 3.5mm headphone jack was canceled, and it was Apple's mobile phone that first canceled the headphone jack, although it was criticized and complained about at the time, Apple still did not change it back, because Apple thought that one more headphone jack would affect the waterproofness of the whole machine, and at the same time, the headphone jack should occupy a lot of space, so that the mobile phone could not be very thin and light, of course, the mobile phone behind it was getting bigger and bigger, but it still did not change back.
The second is that Apple needs to promote Bluetooth headsets, at that time Apple had a new device of Bluetooth headsets, and the price is not cheap, but many people are willing to use wired headsets, Bluetooth headsets are still difficult to promote, so the socket is directly canceled, because wired headsets also need to use adapters, it is more inconvenient to operate, so that everyone has no choice but to use Bluetooth headsets, Apple's Bluetooth headsets have also brought a lot of profits, of course, the sound quality of Bluetooth headsets is indeed much better, Although it is expensive, it can have a better listening experience and will not be that complicated.
Finally, manufacturers follow suit, and Apple serves as an industry benchmark. The 3.5mm headphone jack has been canceled, and the manufacturers have imitated and learned, especially with Apple first, the manufacturers are not easy to be scolded, and the Bluetooth headset market is indeed very good, which can bring higher profits to the manufacturers, this kind of good thing The major manufacturers are naturally willing to do it, so many mobile phones have been canceled, but due to market pressure, it has not been fully changed, in some thousand-yuan machines or hundred-yuan machines, the 3.5mm headphone jack will still be retained, giving the public more choices.
Final summary
In fact, the elimination of each function and design, will bring new functions and design, the times continue to change and develop, the mobile phone industry often has big changes, although many functions are easy to use, but obviously do not meet the future development needs, after the cancellation of the headphone socket, more and more people use Bluetooth headsets, it will indeed be more convenient to use, but if you don't want to use Bluetooth headsets, you can also plug in wired headphones through the converter, but the way is different.
