Spirit Classic headphones have been designed for audiophiles and music lovers. A warm sound combined with the dynamics of the transducers will enable you to find the pleasure of listening to all of your music with wonderful details. Spirit Classic's sound tuning is perfect for listening at home: extended low end, a detailed mid-range and linear top end for a lighter, open sound: all you would expect from Focal. Spirit Classic give its best when the user is at home in a relatively quiet background. There is no need to mask the surrounding noise to enjoy a faithful listening session. Its frequency response curve has been sculpted accordingly: flat in low frequencies, Spirit Classic has around 3dB less bass in comparison to Spirit One.
