Sennheiser HD 660S2: Premium Wired Stereo Headphones with Deep Sub Bass

Experience the dramatic power of bass—from thundering timpani to the melodic strumming of a guitar, from the captivating vocals of your favorite artist to the pulsating beats of electronic dance music. For music enthusiasts, the non-fatiguing, high-end HD 660S2 now brings forth even greater impact and emotion. Engineers meticulously fine-tuned the HD 660S, optimizing its surround, transducer airflow, and coil to amplify the sound pressure at the lowest octaves. Imagine sensing the deepest piano notes at 27.5 Hz or feeling the kick of a bass drum at 45-60 Hz, transporting you to the very studio where the music was recorded, allowing for a nuanced exploration of individual instruments and uncovering new sonic intricacies.

Crafted for enduring comfort, the headphone boasts a relaxed sound profile and an open-back design, ensuring fatigue-free listening even during extended sessions. Its timeless design, accented with elegant bronze touches, exudes sophistication. With its warm tuning, smooth treble, and robust bass, this headphone sets the standard for both prolonged listening pleasure and enhanced bass response. Its natural, relaxed, high-fidelity sound, enriched with extra sub bass, is achieved through an ultra-light aluminum voice coil with a 300-ohm impedance, ensuring excellent impulse response and intimate sound reproduction with remarkable timbre.

Featuring airflow-optimized 42mm high-performance transducers, the HD 660S2 guarantees improved ventilation, thanks to a uniquely potent vented magnet system that minimizes distortion and controls air displacement through steel mesh damping. The result? A doubling of sound pressure at the lowest octaves, allowing you to immerse yourself in the full richness of music, feeling every resonant note and thumping beat as if you were present in the studio during recording.

In addition to exceptional sound quality, the headphone offers unparalleled comfort and build quality. Its open-back design ensures superior breathability, while plush ear cushions provide maximum comfort for prolonged listening sessions. Designed in Germany and meticulously crafted in Ireland, the HD 660S2 exemplifies outstanding quality, with a frequency response spanning from 8 Hz to 41,500 Hz. Plus, its detachable, lengthy cables offer convenience for desktop use, ensuring a seamless listening experience.
