I would appreciate is someone could point me to a link or perhaps share in a nutshell why headphone frequency responses look like they do - I am referring here to the general shape of the chart, and not specifics...
I have been looking at a lot of charts on headroom and comparing phones, and it seems as if in general the shape of the graph remains the same - a gentle hump at around 100-200hz and then sloping steadily downwards to about 4-6khz where there is a series of steep ups and downs...it shocked me the first time - not nearly flat (not sure if the dBr scale is very exagerated) and in the highs such extreme spikes. Is it an inherent problem due to physical constraints of headphones, do manufacturers actually "shape" the curve as such because it sounds good? I am curious and any technical primers into the issue would be much appreciated.
