Can I insert headset to convert messages?

Xiaomi Mijia walkie-talkie supports 3.5mm interface headset , but you need to pay attention to the following two points: ① Headphones without mic can only be used to receive, not work with conversation launch; ② Headphones comes with mic, need to press the walkie-talkie PTT button,launching through the headphone mic hole. Because of the headset structure, a few categories of headphones can not be matched.
