    What do you think of the square wave responses? Especially the 300hz ones. I saw this shape on qdc as well.

      The minimum phase seems legit comparing to the square wave response. Which do you think tells the true story?

      Don't put too much meaning to the square wave; it is not necessary for the data analysis.

    The Bose SoundTrue Ultra IEM has a similar (better?) frequency response.
