Sennheiser HD 660S2 Audiophile Headphones with 4.4mm Balanced Cable

Experience a new level of emotional impact with the Sennheiser HD 660S2 wired audiophile headphones. This high-end bundle includes a specialized 3-meter balanced cable with a 4.4mm connector plug, designed to deliver cleaner, distortion-free sound for the most demanding listeners. Engineered to bring the recording studio experience to your ears, these headphones deliver powerful bass that you can truly feel. By optimizing transducer airflow, surround, and the coil, Sennheiser has doubled the sound pressure at the lowest octaves. This allows you to hear the deep resonance of a piano at 27.5 Hz or the precise kick of a bass drum between 45-60 Hz with incredible clarity. Whether you are listening to the melodic tones of a guitar or the heavy beats of electronic dance music, the HD 660S2 provides a natural and relaxed high-fidelity sound. These headphones are built for music lovers who want to hear every detail, from thundering timpani to the most intimate vocal performances, without ear fatigue.
