Description
The SP540 features the natural fitting D-profile earcup design first featured on the ergonomically designed Koss Pro4AAA. The D-profile mimics the shape of the ear, creating an ideal seal for the most consistent sound reproduction and an incredibly natural fit for extended personal listening sessions.
The full-sized, over-ear, SP540 features the new Koss PLX40 dynamic element, tuned specifically for personal listening.
The D-profile, circumaural design of the SP540 is highlighted by a new contour seal with asymmetrical foam that gradually increases in density near the back and bottom of the cups to balance the pressure around the ear, resulting in a perfect acoustical seal and a balanced fit for comfort. The cushions are comprised of slow recovery memory foam, premium acoustical fabric and protein leather.
