there is a crazy amount of distortion happening when using any logitech device with apple airpods or airpods max devices. doesnt matter if its bluetooth or the bolt receiver, i sound like a robot on all my calls unless i turn off the mx mouse and keyboard then the problem goes away. there are TONS of forums discussing this very issue. PLEASE investigate this as i love both logitech and apple and hate choosing one or the other to co-exist.
