Enjoy your music on a completely new level. An intimate, relaxed sound
signature combines with outstanding precision and exceptional comfort — and
now, extended sub bass — for a deeply moving experience. The extremely
precise yet non-fatiguing sound of the HD 660S2 delivers even more impact
with extended sub bass.
With an optimized surround, transducer airfl ow, and coil our engineers
doubled the sound pressure at the lowest octaves. You can feel the lowest
note on the piano (27.5 Hz) or the kick of the bass drum (45-60 Hz) as if you
were there.
The relaxed tone and open-back design make this extremely comfortable
headphone great for long sessions. With warm tuning, smooth treble, and
strong bass, the standard-setter for extended listening is now the standard-
setter for extended bass as well.
