I am aware that beats does not publish anything beyond their frequency response. Is there any way to obtain this information? I want to be able to have solid evidence against beats when someone approaches me about it.
The graph shows the loudness (emphasis) a headphone/speaker has for certain frequencies. Left to right is lows to highs. Flat is the most accurate, bumps in the low frequencies (left) means bass emphasis. Lots of up and down spikes in the highs is normal, most headphones have at least a little spiking. With headphones, what comes out of the headphone as flat may not be heard as flat because of the way it hits your ears and how close the driver is to your head. I don't know enough else to comment on how to compensate for that in graphs, however, though I do believe some graphs have already factored that in.
