USB-IF (USB Implementers Forum) organization has established the specification for USB Audio Device Class 3.0 standard, which allows sending audio through the USB type C interface. As you can read in the official statement, this new standard was specified in order to use of the same connector for charging, data transmission and connection of multimedia devices.
It is difficult not to refer to the revolution introduced by Apple during the launch of the iPhone 7. Many people have criticized Apple for removing jack audio interface in their latest smartphone. However, I suspect that for some time the same action will be taken also by other manufacturers. This statement does not apply only to mobile phones, because this old audio interface will be replaced by USB type C also in other devices. The biggest advantage of USB Audio Device Class 3.0 standard is the compatibility between devices manufactured by different companies. Of course, you will still be able to use your favourite headphones, because the appropriate adapters will be available. USB type C has more and more applications and I hope that we will not have to wait too long for its popularization.
USB Type C currently replaces traditional micro USB interface.
For the average user the greatest (and currently perhaps the only) advantage of the new USB type C connector is its symmetry, which takes care of the problem of “plugging at the 3rd attempt”. However, the interface is so versatile that it allows the transmission of up to 100 W of electricity at a voltage of 20 V. This way we will soon get rid of the problem of different charging interfaces used in laptops. I only wonder how long Apple will continue to flounder in the use of their Lightning interface. It is very similar to the USB type C, but the USB Audio Device Class 3.0 devices will not be able to be used together with the released recently iPhone 7. Frankly, the existence on the market of two very similar solutions always ends the dominance of one of them and complete elimination of the loser. This was, for example, in the case of Blu-ray and HD-DVD.
