The K553 MKII is a closed-back, over-ear studio headphone for monitoring, mixing, and mastering applications. It was designed to provide the perfect balance between the noise-isolating qualities of a closed-back headphone and the spacious, dimensional sound of an openback design. The 50mm drivers provide a strong, yet accurate and distinguished bass response, as needed when monitoring and mastering contemporary music. The extra-large, soft ear pads ensure comfortable, stress-free listening for hours, and the 2D-axis mechanism enables flat folding for easy storage or handling when on the road. With its low-impedance drivers, it is sensitive enough to be used on laptops and mobile devices, making them ideal for travel or critical listening on any device. The soft high-quality detachable cable is equipped with a 3.5mm (1/8") plug, with a screw-on adapter to 6.3mm (1/4") also included.
