(Milwaukee, Wisconsin) November 21, 2016 – 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 Porta Pro Limited Edition in two colorways, which were both chosen by Koss fans worldwide. In July, Koss initiated the “Make Your Mark Campaign”, which allowed Koss Fans from around the world to vote on five unique colorways for the Porta Pro Limited Edition. After thousands of votes, the campaign resulted in a tie. Koss elected to produce both colorways: Black Gold and Rhythm Beige. The Porta Pro Limited Edition is more than two updated colorways. The new models feature an inline microphone and remote, along with an attenuating volume control. Included with the new Porta Pro Limited Edition is an all-new hard compact carrying case (the standard Porta Pro Classic case is also included). The Porta Pro Limited Edition ships direct only from Koss.com in a special Limited Edition, “direct-to-consumer” package. “The engagement and excitement around the Porta Pro Limited Edition has been incredible,” said Michael J. Koss, Jr. Vice President Marketing & Product. “The sheer volume of votes and traffic went well beyond our expectations. Both versions of the Porta Pro Limited Edition maintain the incredible Sound of Koss with a fresh new look.” The Porta Pro Limited Edition is available in two colorways: Black Gold and Rhythm Beige. Both are available today exclusively at www.koss.com for $59.99.
