Recently, Shen Yiren, vice president of oppo, posted a microblog and asked netizens whether they think it is necessary to keep the 3.5mm audio port at the same time?

Should the 3.5mm audio port be reserved

On this issue, many netizens expressed their views. Netizens said they wanted to keep it. It was too troublesome to take two lines out and a converter. Some netizens said that the Bluetooth headset was too late, and some netizens said that they could not listen to music when charging, and could not charge when listening to music.

Whether it is necessary to keep the 3.5mm audio port in the end starts with why it was cut off at the beginning.

In 2016, the iPhone 7 slashed the 3.5mm audio port. Subsequently, some major mobile phone manufacturers followed the new generation “trend” and started to use the 3.5mm audio port. You can’t cancel the audio port for no reason. You must see its advantages.

Indeed, first, canceling the 3.5mm audio port meets the requirements for lighter and thinner fuselage. The thickness of the 3.5mm interface will be slightly thicker than the data interface. After canceling the 3.5mm audio port, the fuselage is allowed to be thinner. In addition, after canceling the 3.5mm interface, the body space becomes larger. For mobile phones, which pursue extremely compact internal structure, the space can be further optimized by reducing one content, and the battery capacity of mobile phones can become larger.

Second, the sealing function of the fuselage is strengthened. Both dust and water have a great impact on the service life of mobile phones. Canceling the 3.5mm earphone hole can effectively prevent dust and water. Although Samsung and Sony have 3.5mm earphone holes, they can also be waterproof. That’s because the interface is coated with nano coating, which is the effect of external effect rather than the mobile phone itself.

Third, improve the sound quality. The change of the interface actually changes the quality of the transmission signal. In the past, the processed analog signal was transmitted through the interface, while the unprocessed digital signal was output through lightning interface, USB type-C and other interfaces, which has more plasticity, possibility and interest.

Since there are many advantages of canceling the 3.5mm audio port, why discuss whether to keep it?

The main reason is that the successor to the perfect replacement of wired headphones has not yet appeared, and the delay problem of Bluetooth headphones has always been a mystery. In the process of using Bluetooth headset, clutter interference is too serious. If you disconnect with Bluetooth headset outdoors, the probability of instability is much greater than that indoors.

Secondly, the problem of endurance. Using the 3.5mm audio port, the headset can be used as long as the mobile phone rings, while few in ear Bluetooth headsets have a double-digit endurance.

In addition, you can’t charge when listening to music, and you can’t listen to music when charging. In view of this, many manufacturers have launched dual adapters with 3.5mm and type-C charging ports. On the one hand, the dual converter is large and inconvenient to carry. On the other hand, many people use the converter and find that the fast charging of mobile phones is missing.

So there’s no other way? Consumers can purchase type-C connector headphones. However, there are problems. First, it can only be used on typc-c devices. Second, its own type-C headphones can only use its own mobile phone. For example, Xiaomi typc-c noise reduction headphones can only recognize OTG audio devices when used on Samsung devices, that is, there is no sound when listening to voice on the phone.

For all these reasons, by 2019, some mobile phone manufacturers have begun to consider whether to retain the 3.5mm audio port. In fact, retaining the 3.5mm audio port can indeed avoid many troubles. Not retaining the 3.5mm audio port can also accelerate the solution of the delay problem of Bluetooth headset. Do you think you want to keep the 3.5mm audio port?
