Sennheiser Consumer Audio HD 660S2 – Wired Audiophile Stereo Headphones with Deep Sub Bass, Optimized Surround, Transducer Airflow, Vented Magnet System and Voice Coil – Black

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.
