Reason why headphones seldom use TYPE-C interface

Now many mobile phone chargers have begun to widely use the TYPE-C interface, such as Huawei mobile phones. Because this interface has many advantages: firstly, it can be used on both sides, which is more convenient for charging, and secondly, the charging speed is faster. Under the UCB PD power transmission protocol, the TYPE-C interface can realize 100W current transmission power. Since this interface has these advantages, why can&＃39;t it completely replace the 3.5mm headphone jack?

According to the analysis of people&＃39;s demand for headphones, the demand for headphones with TYPE-C interface is not high at this stage, and only some mobile phone users need this type of headphones. Most devices still have 3.5 headphone jacks, and there is a great demand for such headphones. There is also a headphone jack converter on the market. After conversion, headphones with TYPE-C interface can be used on the 3.5 headphone jack. For earphone manufacturers, they will not lose most customers in order to please a few customers.

From the perspective of earphone manufacturing technology, there are some technical defects in TYPE-C interface. At present, there are two types of headphones with this kind of interface: one is with dac and the other is with decoding chip; Second, there is no separate decoding chip, just a pure analog signal line. At present, there is no unified audio standard for C-type USB interface in China, and different mobile phone manufacturers have different output digital signal protocols, which makes it more difficult to manufacture TYPE-C interface headphones. When a headset product is not compatible, it will not meet the needs of different customers at the same time.

According to the current development and application of TYPE-C interface, it is difficult for earphone manufacturers to overcome various difficulties to produce earphone products with C-type USB interface. With the continuous development of the times, after the TYPE-C interface is more widely used, the 3.5mm headphone jack will be gradually eliminated, and the C-type USB interface headphones will become the mainstream products of headphones.
