The matte ivory HD-599 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.
