Koss Pro 4AA became the studio standard in the USA in 1970. Today, Koss has further developed it with a new main frame, titanium-plated polymer diagrams and oxygen-free copper-clad aluminum number coil. It is heavy and very insulating. It can handle very high volume without cracking the elements. The soft air-filled ear cushions close very tightly around the ears and provide very good attenuation against ambient sounds. New main arch is designed for best comfort and maximum durability for DJs and music studios.
