Mic issue on the left side if i use it as streo way

Brother only liberty air 2 is connected but i can hear from both them but only the right bud mic is working not the left one
Is it passively connected left one with right? that’s how it is? PLEASE URGENT HELP
Both mic should work simultaneously right? but if both are connected then only the right bud mic works
or is just ankers way?

I’ve searched high and low and don’t see an answer to this. Am I missing something?
thanks

I got the same issue. so far no solution

I’m a little confused. How can you tell which mic is being used, and what difference does it make? As long as it is picking up the sound, you should be good to go, right?
