Apple for the first time in its iPhone 7/7 Plus canceled the 3.5mm headphone jack, presumably we also guessed that this seemingly small change will inevitably appear in other mobile phone brands. And the fastest non-Samsung is the "follower".
According to the latest news, Samsung may follow the iPhone 7, canceling the 3.5mm headphone jack on its Galaxy S8, which will be released next year, and will release an adapter to be compatible with existing headphones. However, unlike Apple, Samsung's approach is to create its own dedicated headphone jack, rather than using USB-C, or even the Lightning interface.
It is reported that before the iPhone 7 was released, Samsung has been developing a dedicated headphone jack, which is likely to be compatible with the iPhone. According to foreign media, Samsung’s plan is to establish a no-cost or very low-cost headphone interface standard and hopes that other Android handset brands will adopt this standard. Samsung representatives currently refuse to comment on this rumor.
In an article before Lei Fengwang (searching for the "Lei Feng Net" public number) (an audio revolution of iPhone 7: Does Lightning really replace the 3.5mm audio interface?) introduces several major drawbacks of the 3.5mm interface:
The 3.5mm interface can only transmit AC level signals within 2V, but the current is at the milliampere level and the power is very small, so there are limitations in the expansion;
3.5mm's own volume limit, if you cancel this interface, you can make the phone more light and thin;
Compared with the 3.5-mm interface, Lightning interface, and Type-C interface, this interface does not solve the power supply problem of the external device.
So it is reasonable for Samsung and other mobile phone brands to cancel this interface or to develop more advanced interfaces.
