With linear acoustics tailored for extended listening sessions and smooth, rewarding bass performance, the HD 560S was crafted for analytic audio enthusiasts. The HD 560S delivers the linear performance demanded by analytic audio enthusiasts at a revolutionary value, allowing the listener to have an honest look inside their music, whether for pleasure or productivity. The HD 560S features an open-back design that provides natural propagation of sound waves. The angled alignment of the EAR (Ergonomic Acoustic Refinement) driver recreates the optimal triangular listening position you'd find in hi-fi speaker setups and high-end recording studios. This combination creates a large, articulate soundstage without the need for room treatment, allowing you to hear the neutral version of your music unaffected by the artifacts of a confined space.
