There is a target curve for headphones that most companies tune to. It is a very good curve. We started there, and then we listened.
Measured right, sounded wrong
Our first prototype matched the target within half a decibel. Everyone in the room agreed that cellos sounded like they were in the next room. So we moved the 2 kHz shelf — nine times.
Four genres, one curve
Jazz, techno, string quartets and audiobooks. If a change made one better and another worse, it went back.
