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.
With a frequency response of 12 to 38.5 kHz, these headphones offer uncompromising sound. There is no pressure on your ears, only sound. Listening to track after track you will discover what you haven't even heard yet. They include a 9.8' cable with a 1/4" straight plug, a 3.9' cable with a 1/8" straight plug, and a 1/4" to 1/8" headphone adapter.
