Sennheiser HD558

Description

Sennheiser's innovative "Eargonomic Acoustic Refinement" (E.A.R.) design channels audio signals directly into your ears. State-of-the-art, advanced Duofol diaphragms deliver transparency and minimal distortion, while highly optimised, field-strengthened neodymium ferrous magnet systems yield an excellent dynamic response. A surround reflector creates an extended spatial sound field for the lightweight aluminium voice coils chosen for high efficiency and excellent dynamics. The special diaphragm geometry reduces intermodulation distortion, while highly constant, compressed cellulose fleece reduces total harmonic distortion.
