The HD 660 S is the successor to the legendary HD 650. This open-back, dynamic headphone features new lower (150-ohm) impedance transducers producing reference-class sound when connected to both Hi-Res home or mobile audio systems. An elegantly designed piece of German engineering, the HD 660 S delivers exceptionally accurate and transparent sound, with an expressiveness that immerses the listener in every emotion and nuance of the music.

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 employees newly designed transducers featuring extremely lightweight aluminium voice coils coupled to diaphragms precision crafted from stainless steel fabric. This combination results in exceptional transient response and improved control of diaphragm movement reducing distortion. Additionally, transducers are produced and matched to extremely tight (± 1 dB) tolerance guaranteeing superb performance.

The HD 660 S is supplied with two para-aramid reinforced detachable cables employing high conductivity OFC copper to ensure 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.

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 assure hours and hours of supreme listening pleasure.

Features:
  • Reference-class open dynamic headphones
  • New improved transducer design for very low harmonic distortion
  • Hand-selected headphone drivers with precise left and right matching tolerances (± 1 dB) for accuracy
  • 150 Ohms nominal impedance to allow direct connection to both stationary and mobile HiRes players
  • Para-aramid reinforced, detachable cables made from highly conductive OFC copper, with very low handling noise
Dimensions:
D x W x H: N/A
