Very nice article bravo.
I thought it might be nice to add a reference from Yamaha (I don't work for them but like language and technology) on "orthodynamic"

Also from Yamaha:
"First introduced in 1976, the HP-1 represented our first entry into the headphone market. It was a product that had many unique features. Yamaha engineers had developed a manufacturing method to sandwich a very thin polyester “orthodynamic” diaphragm embedded with a thin copper conductor in-between two specially designed magnet structures. Similar in concept to the electrostatic speakers being experimented with at the time, the sound was open, full range and very musical. In addition, the skills of renowned Italian industrial designer Mario Bellini were tapped to create the look and feel of these headphones. Their open headband and fabric head strap made them extremely light and comfortable, good for hours of non-stop listening. Versions of the HP-1 (including the YH-1000, YH-100 and HP-1A) were released all the way into the mid-1980s."
