The Koss Pro4S Studio Headphones are specifically crafted for professionals who use headphones every day to create the world's greatest music. Featuring the SLX40 element, tuned for reference, the Koss Pro4S studio headphones deliver an incredibly accurate and unbiased sound, perfect for any studio or creative environment.

The Pro4S studio headphones feature the natural fitting, iconic “D-profile” earcup, 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 a comfortable, natural fit for extended creative sessions.

Designed for the rigors and wear of professional use, the Koss Pro4S headphones feature a rugged mechanical design using the most durable materials. Aluminum earcups with memory foam cushions wrapped in soft protein leather make Koss' Pro4S studio headphones structurally strong but surprisingly comfortable.

An all-new integrated, metal-on-metal assembly of the headphones makes the Koss Pro4S extremely robust in areas where other headphones often fail. The metal headband is cushioned by soft foam wrapped in breathable mesh, perfect for extended use.

The Koss Pro4S headphones feature a detachable cord with dual-choice entry, allowing the user to choose which earcup to connect to for optimum adaptability. Once the cord is attached, the opposite side becomes an output, allowing pass-through listening or daisy chaining for extended monitoring. The Koss Pro4S studio headphones fold flat into a travel case for easy portability.
