Product details


Crafted for the demanding listener, the HD 660 S surpasses the performance of its predecessor, the legendary HD 650. Detailed and dynamic, with an extended and balanced frequency response the HD 660 S is both exceptionally accurate and musically expressive. The lower 150-ohm impedance facilitates direct connection to both premium home and mobile audio devices.

The HD 660 S is designed for pure listening pleasure. It’s open-back architecture is strong yet lightweight, and allows airflow to the ears keeping them cool during listening sessions. The large elliptical ear cups are shaped following the anatomy of the ear, and feature soft velour covered ear cushions. Thick headband padding complete the comfort package to guarantee hours and hours of supreme listening pleasure.

The HD 660 S is supplied with two para-aramid reinforced detachable cables employing high conductivity OFC copper to insure signal integrity with very low handling noise. One cable is terminated with a 6.35mm stereo plug (a 3.5mm adaptor is also included), the other with the new 4.4 mm Pentaconn balanced stereo plug. Balanced connectivity can reveal full HD 660 S performance potential when paired with the balanced output of digital audio player or headphone amplifier like the Sennheiser HDV 820.

Thanks to its lower impedance, it delivers reference-class sound also when connected to hi-res mobile players, thus offering much greater versatility. The HD 660 S is an elegantly designed piece of high-quality engineering that indulges the demanding listener with aural precision and great wearing comfort.
