Nothing makes music feel dramatic like powerful bass. The extremely precise yet non-fatiguing sound of the HD 660S2 now delivers even more impact with extended sub bass. Our engineers optimized the HD 660S's surround, transducer airflow, and coil to double 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.
