The current mobile phone has basically cancelled the Audio3.5 headphone interface, to achieve audio or microphone functions, can only be connected to the only Type-C interface on the mobile phone, at the same time, the only Type-C interface on the mobile phone is also the interface for charging the mobile phone. So, during the broadcast, the battery died. My phone died during the video conference. Isn't it awkward? It delays things. These can be solved with this wireless lapel microphone solution that supports charging the phone (fast charge).
