Product details

The Koss Pro4S has been specifically designed for professionals who use headphones daily to create significant music worldwide. It delivers an incredibly accurate reproduction of your music, making it perfect for any creative environment. Other music lovers can also enjoy the brilliant sound of the Pro4S. The Pro4S features D-profile ear cushions that mimic the shape of your ears and feel very natural. The ear is ideally sealed, allowing you to enjoy optimal sound quality even over extended periods. Since the Pro4S is built to meet the high demands of a professional environment, it incorporates high-quality components such as aluminum ear cups and foam ear pads. This makes the Pro4S both robust and comfortable. The detachable headphone cable distinguishes the Pro4S with its dual connection principle. The headphone cable can be connected to both ear cups, allowing for optimal adaptability. While one side is used for connection, the other side can serve as an additional headphone output for listening to music together. The Pro4S is foldable and comes with a carrying case for on-the-go convenience.
