It is? It is the thing that explains the dips you were worried about. Not some magical weakness in measurements. Take a $5 mic, put it in a flat plate and measure some headphones and then come back to complain when you know something about this process. Your constant protests on these threads is becoming so annoying. You are in serious danger of being shown the door. The review threads are not for empty complaints.
Do I feel some negative attitude? Robert Redford thing was a good sample of that.
You write test reports.
I read them and may have concerns.
You provided this FB forum, and I am happy to use it and comment.

I understand that having only guys posting thank you messages would be better, but there are also guys who may have different ideas, questions or remarks. I think it's natural.
