Step Up Your Soundstage

An audiophile standard in the world of open-back headphones, the HD 660S from Sennheiser all but eliminates the barriers between listener and music. Improving on the acclaimed HD 600 and HD 650 models with an all-new transducer and specially ventilated drive unit to consistently control air displacement, the HD 660S takes a step forward in both detail and dynamics. Within each driver’s 38-millimeter diaphragm, an aluminum voice coil delivers exceptional agility and responsiveness to articulate all areas of the frequency spectrum. Encasing this hardware, an open-back design made from steel mesh completes the new ventilation system, giving the HD 660S a wide-open, natural sound and a sleek presentation.
