Unfortunately it may be true! Dhruv made some comments about pinna gain as well as some previous commentary on old peoples negative sensitivity to higher frequesncy..I am 57 years old and when I put them in my ear, they sound great...his understanding may hold the key as to why. (and yes, that 2% shimmer is now bothering me!). I believe you have the same mic (umik1) and REW setup as me...have you finished your coupler as I'd like to see how your rig compares.That looks absolutely great!! Though, from that curve it looks like you have dropped almost 50db at 6k? Surely that can't be true?
Last, he commented on the Lpad for the sonion, but really for its LP abilities. I'm sure you would lke to see that explanation as I thought it was only to tame the DB...
