The HD 558 headphones from Sennheiser provide high-quality audio in a lightweight and stylish design. With premium metal mesh and high-gloss burl wood accents, the headphones have innovative Ergonomic Acoustic Refinement (E.A.R.) technology that channels audio directly into your ears for realistic sound reproduction with deep bass that simulates sitting in front of a set of hi-fi speakers without the expense or space requirements. Internal sound reflectors generate an extended spatial sound field for an immersive audio experience. The headphones have an extremely fast rest/response time for excellent transient response and treble clarity.
Advanced Duofol diaphragms with neodymium magnet systems and aluminum voice coils provide transparent audio with minimal distortion, high dynamic range, and excellent efficiency. Designed for lasting comfort, the headphones have a padded, adjustable headband and extra-thick around-ear velour cushions. The single-sided detachable cable has a twist-n-lock mechanism that minimizes tangles and is easy to replace. The cable has a gold-plated 1/4" stereo plug and includes a 3.5mm mini plug adapter for wide compatibility with a variety of pro and consumer audio devices.
