Technical questions

What does flat frequency response mean and how do I benefit from it?

Normally the frequency response of headphones is not flat. It contains notches and bumps, especially in mid- and high-frequency sections. These have an effect on the perceived sound quality. The flat frequency response, however, is flat across the whole frequency range. As a result the headphones do not make any changes to the sound quality. In addition to the flat target a natural (HRTF-based) target can be chosen.
