Actual Frequency?
For years, makers of Head Set devices (Harman Kardon, Bose, Sony, and of course, Stenhauser.) have published the Frequency Response and response curves of their headsets. I see a LOT of secondary garbage about the EarPods that don't talk about Anything concerning Frequency Response and Curve (Base, mid range, upper).
Apple. If you want to be a Music Company, Publish the real response of the devices. Until then, I'll just have to stick to my Harman Kardon.
