I recently purchased an Anker Bluetooth Headset, and i had the common issue that it sounds like garbage when i pair it on my MacBook but awesome using my iPhone
The issue is fixed by turning "Input" to "Internal Mic" in
Settings > Sounds > Input
But the thing is.. i have to do it EVERYTIME i connect my earphones! If i need to charge them, the second time i turn them on, i have to do the same process again, is there a way to make this the default behavior??
BTW, i'm using High Sierra
