Some friends earlier mobile phones are still in use, with five or six years is too late to think about new, but a look at the market of mobile phones, configuration improvements and various changes are very big, do not take some time to understand it is really do not understand, after so many years of development, the mobile phone industry has already been turned upside down, during this period, mobile phones have brought a lot of new features and new designs, At the same time, many old features and old designs have been eliminated, including the headphone jack.

     Before the bottom of our mobile phone will have a number of interfaces, in addition to the charging port will also have a headphone hole, can be inserted into the wired headphones to listen to music, but now want to plug the headphone hole, you need to use the converter to plug in the charging port, many new mobile phones only this interface, and the previous 3.5mm headphone hole is basically cancelled. Only a few thousand yuan machine or hundred yuan machine will have a headphone jack, those mid-end machine or high-end machine, basically unified is the use of USB interface, so why in the end will cancel this jack? In fact, the reason is very real, read the following three points to understand.

     First of all, due to the consideration of water resistance and thin design, the 3.5mm headphone jack was canceled. The first one to cancel the headphone jack was Apple mobile phone, although it was criticized and ridiculed at that time, Apple still did not change it back, because Apple thought that an extra headphone jack would affect the water resistance of the whole machine, and the headphone jack would occupy a large space. So that the mobile phone can not be very thin, of course, the phone behind the bigger and bigger, but still not changed back.

     The second is that Apple needs to promote Bluetooth headphones, when Apple has Bluetooth headphones this new device, and the price is not cheap, but many people are willing to use wired headphones, Bluetooth headphones are still difficult to promote, so directly cancel the jack, because wired headphones also need to use an adapter, the operation is more inconvenient, so we can only use Bluetooth headphones. Apple's Bluetooth headset has also brought a lot of profits, of course, the sound quality of Bluetooth headphones is really much better, although the price is expensive but you can have a better hearing experience, it is not so complicated.

     Finally, manufacturers follow the trend, Apple as the industry benchmark, have canceled the 3.5mm headphone jack, the manufacturers have to imitate learning, especially with Apple first, the manufacturers are not easy to be scolded, and the Bluetooth headset market is really good, can bring higher profits to the manufacturers, this kind of good manufacturers are naturally willing to do, so many mobile phones have been canceled, However, due to market pressure, there has been no comprehensive change, and in some thousand yuan machines or hundred yuan machines, 3.5mm headphone holes will still be retained to give the public more choices.

Final summary

     In fact, the elimination of each function and design will bring new functions and designs, The Times are constantly changing and developing, and the mobile phone industry often has big changes, although many functions are good to use before, but obviously do not meet the future development needs, after canceling the headphone jack, more and more people use Bluetooth headphones, it will be more convenient to use, but if you do not want to use Bluetooth headphones, Wired headphones can also be plugged in through a converter, but in a different way.
