The Pro4S Studio Headphone is specifically crafted for professionals who use headphones every day to create the world's greatest music. Featuring the all-new SLX40 element, tuned for reference, the Pro4S Studio Headphone delivers an incredibly accurate and unbiased sound, perfect for any studio or creative environment.

The Pro4S Studio Headphone features 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 an incredibly natural fit for extended creative sessions.

Designed for the rigors and wear of professional use, the Pro4S Studio Headphone features an incredibly rugged mechanical design using the most durable materials. Aluminum earcups with memory foam cushions wrapped in soft protein leather make the Pro4S Studio Headphone structurally strong but incredibly comfortable.

An all-new integrated, metal-on-metal assembly of the headphone makes the Pro4S Studio Headphone 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 Pro4S Studio Headphone features 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 Pro4S Studio Headphone folds flat into a travel case for easy portability.
