The HD 660 S 2 Audiophile Headphones thundering timpani, melodic sound of a guitar, impressive singing voice of your favorite artist, and beat of electronic dance music, nothing creates drama like powerful bass. Ideal for music lovers, the non-fatiguing, high-end HD 660S2 now delivers even more impact and emotion. 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 at the recording studio, allowing you to pick out individual instruments and discover new sonic details.
- Natural, relaxed, high-fidelity sound with extra sub bass: Ultra-light aluminum voice coil with 300-ohm impedance for excellent impulse response and an intimate sound with great timbre
- Airflow-optimised 42mm high-performance transducers: Improved ventilation due to a uniquely powerful vented magnet system for minimal distortion and air displacement control through steel mesh damping
- 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, at the recording studio
