Headphone frequency response graphs look very different from those for loudspeakers, which are ideally very flat. Here you can see a big rise on the right (treble) side and then it falls off a cliff. But this is in fact very close to what’s considered ideal for headphones. Because leading manufacturers base their goals on extensive psychoacoustic research about listeners’ subjective preferences.

For instance, it turns out that headphones negate the function of the outer ear, which otherwise amplifies sounds in the 3 kHz region. So, the ideal response for headphones is much higher there. Resonances in the inner ear also make sounds between 7 and 10 kHz louder, which is why the graph dips abruptly around 8-9 kHz. We can see here that the HD 550 builds on the already excellent characteristics of the HD 599, extending even further into subbass territory while still offering strong, analytic mids and brilliant treble without sibilance or harshness. The graph reflects the HD 550’s solid, satisfying bass response, balanced midrange, and precise and airy treble.
