The HD 560S was developed with linear acoustics and powerful bass for demanding music enthusiasts. Music lovers enjoy their music on a variety of devices - with dedicated amplifiers, audio interfaces and also directly from the PC. The HD 560S offers linear acoustics and high precision at an affordable price. Whether for music enjoyment or as a means to an end, the HD 560S reproduces the source material transparently. With its open design, the HD 560S allows sound waves to expand unhindered, thus preventing the disruptive reflections of the closed design. Sennheiser's E.A.R. (Ergonomic Acoustic Refinement) technology with angled transducers imitates the sound directivity of stereo loudspeakers. This combination enables a natural, wide stage and localised fine detail of instruments that is far superior to other headphones. The HD 560S's high-performance transducers are specifically designed for precision at the edges of the audible frequency spectrum, making them ideal for reliable A/B testing of components, mixes and a wide variety of audio formats. They are broadband neutral and also reveal sound ranges where conventional speakers often fail - between 20 and 50 Hz. The brand new 120 Ohm transducer with an innovative polymer blend cone enables a highly linear excursion and optimised brilliance at frequencies above 10 kHz. The powerful magnets ensure high impulse fidelity, while the finely tuned damping compensates for turbulence and delivers dry, powerful bass - connoisseurs can hear the difference. The HD 560S is a reliable playing partner in any situation, guaranteeing hours of fatigue-free listening. Even though the sound of the HD 560S is based on the modern classic HD 660S, the mechanics were developed on the basis of the lightweight and robust 500 series.
