Sennheiser has updated its HD 660 , expanding the capabilities of the 600 series, a long-standing model of high-performance headphones for audiophiles. Detailing with an engaging frequency response, the headphones deliver a more dramatic listening experience with greater intensity thanks to enhanced sub-bass tuning, extracting dynamic impact and emotion from audio enthusiasts’ favorite recordings. The upgraded acoustics offer a new, great way to enjoy your music again and again.
Across the entire frequency range, the Sennheiser HD 660S2 delivers excellent listening quality thanks to improved transducer airflow and an improved voice coil. From thunderous timpani crescendos to pulsing EDM surges, even the most discerning audiophile will notice the depth and nuance of low-frequency passages that add drama to any type of music.
Ultimately, listeners get deeper and clearer bass without sacrificing the outstanding detail that this series is known for. By reducing the weight of the voice coil, the impulse response is improved, bringing hyper-realistic textures to the fore during playback of any performance. The overall impression is smoother and warmer than the original HD 660S, thanks to the reduced distance between selected peaks and troughs.
The soft ear cushions and padded headband place the updated 300 ohm drivers at the optimal distance from the ear, providing a spacious soundstage with plenty of detail even for extended musical exploration. The surround converter lowers the resonant frequency from 110 Hz (the original HD 660S) to 70 Hz for easy movement of powerful drums. Even the outer mesh grills are designed to manage airflow with the perfect impedance for refined listening sessions.
