Koss Extends Legacy with the Development of the New Pro4S Studio Headphone (Milwaukee, Wisconsin) November 11, 2014 – Koss® Corporation (NASDAQ Symbol: KOSS), the U.S. based high-fidelity Stereophone manufacturer and inventor of the world’s first SP3 Stereophone in 1958, announced the release of the evolutionary Pro4S Studio Headphone. "Ever since we invented our first pair, recording professionals have turned to the Koss Pro4 Studio Headphones as their reference headphone of choice," said Michael J. Koss, President and CEO. "The all-new Pro4S Studio Headphone continues Koss' legacy of incredible accuracy and great fit." 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 clean, natural sound and fit of the Pro4S Studio Headphone make them the perfect reference headphones for today’s multi-platform recording sources,” said Koss. 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. The Pro4S Studio Headphone ships today and is available at Koss.com and Amazon.com, with a choice of regular retail packaging or Amazon-certified Frustration Free Packaging (FFP), for $149.99.
