Ergonomic headband and over-ear design ensures exceptional wearing comfort with full-size ear cups and soft replaceable earpads. Phone-friendly For complete convenience, the HD 569s come with two cables; an audio cable for pure home listening, and one featuring a one-button remote and mic so you can manage your phone calls with ease when out and about.
