A 3.5 mm adapter is required to operate by inserting the charging port.
So at present, in my personal understanding, the market can be generally divided into two kinds of adapters: one is as a pure transfer carrier, and the second is the main HIFI or sound quality of the ear cable.
It is very easy to understand, in simple terms, it does not come with a special DAC, just a pure adapter, such as this green link is a typical converter head. The main problem of this type is that the signal loss is large, and there is a certain background noise. However, if you only use daily assistance and have no need for sound quality, it is recommended to choose this, there is no need to use DAC. Especially for friends who want a wired connection to play games (such as Peace Elite), I recommend that you use this type of adapter, which is durable and does not require the so-called sound quality itself.
