From thundering timpani, to the melodic sound of a guitar, the impressive singing voice of your favorite artist, or the 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. The relaxed sound and open-black design make it an extremely comfortable headphone that is also suitable for long listening sessions. The headphone's warm, relaxed sound is reflected in its timeless design and elegant bronze accents. With warm tuning, smooth treble and strong bass, the standard-setter for extended listening is now also the standard for extended bass.

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
Exceptional comfort and build quality: The open-back design offers exceptional breathability and the plush ear cushions deliver maximum comfort - for long listening sessions
Outstanding quality designed in Germany, made in Ireland: With a frequency response of 8 Hz - 41,500 Hz and detachable, long cables for comfortable desktop use
