FOR IMMEDIATE RELEASE INTRODUCING THE KOSS INTERLOCKING IN-EAR STEREOPHONES Las Vegas, NV USA – January 11, 2012 – Koss Corporation, the Milwaukee, Wisconsin based high fidelity stereophone manufacturer and inventor of the world’s first SP/3 Stereophone in 1958, has revolutionized the design of the in-ear stereophone with the release of the interlocking in-ear stereophones. “We were especially interested in developing an in-ear headphone that was unlike anything else available,” commented Michael J. Koss, President and CEO of Koss Corporation. “Our goal throughout the design phase was to create an original product – one that offered an innovative design and that also produced the authentic Sound of Koss.” Koss creates perfect harmony between form and function. The interlocking in-ear headphones utilize an ingenious patented design for easy on-the-go storage without sacrificing richly delivered audio through performance tuned 9mm drives. The frame of the new interlocking in-ear headphones is constructed from highly polished aluminum and surrounded by flexible, soft touch material. This innovative material doubles as a soundproofing coat, intended to deaden any unwanted distraction, allowing the listener’s focus to remain on the crystal clear highs and crisp lows. “We have seen so many earbuds and in-ear headphones that miss the mark in design, fit and sound,” Koss said. “Our design team is committed to creating original stereophones that enable our listeners to become as close as possible to the music they love.” The interlocking in-ear headphones are available in two configurations and will also be offered in various color varieties throughout the year. The IL100 is the standard in-ear headphone which features the world renowned Sound of Koss and the patented interlocking design. The IL200 KTC, includes Koss Touch Control (KTC) remote and microphone technology made for iPhone®, iPad® and iPod®. KTC allows listeners to stay connected, shuffle songs and adjust volume with an easy flick of the switch. “It’s really interesting to look at the stereophone market today and compare it to the industry my father helped create in the 1950’s – a lot has changed, but what has remained constant is the authentic and original design, fit and Sound of Koss,” Michael Koss said, “We are really excited to offer an evolutionary product based on our revolutionary introduction in 1958.” The IL100 and IL200 KTC interlocking in-ear stereophones will ship in early Spring 2012.
