Most of the tests I found put the headphones on a dummy head with microphones of good dummy ear canal. AB & K 4128 is a well-head doll of this type. But these types of systems seem to respond only up to 10 kHz, and we measure the headphones up to 20kHz. What equipment is used to couple a microphone headset very good at measuring quality?
