Product Overview
The Sennheiser HD 560S is a wired open-back over-ear headphone designed for analytical music listening and home audio use. Article number 509144 identifies this configuration. The headphones use dynamic 38-millimeter transducers and a circumaural design in which the ear cushions surround rather than rest directly on the ears. The open-back enclosure allows sound to pass through the rear of the earcups instead of isolating the listener from the surrounding environment.
The HD 560S has a documented frequency response of 6 Hz to 38 kHz and a nominal impedance of 120 ohms. The detachable cable provides a wired connection for compatible headphone amplifiers, audio interfaces, receivers, computers, and other playback equipment. An adapter supports equipment using a different common headphone-jack size. Because the design is open-backed, outside sounds remain audible and music can also be heard by nearby people. These characteristics make the headphones more appropriate for controlled indoor listening than for environments where sound isolation is required.
