The matte gray HD 579 Open-Back Around-Ear Headphones from Sennheiser are a successor to the popular HD 500 series and are powered by Sennheiser's proprietary transducer technology including the "Ergonomic Acoustic Refinement" (E.A.R.) design, which channels the audio signal directly into your ears. They can be used to deliver high-end audio performance and offer exceptional wearing comfort thanks to the large earcups, broad-padded headband, and soft replaceable earpads.
Featuring a contemporary design that is both attractive and ergonomic, they are a real treat for all who listen to their music with a sense of discovery. The headphones also include a 9.8' detachable cable with a 1/4" connector, and a 1/4" to 1/8" headphone adapter, which make them compatible with a variety of devices and home entertainment systems.
