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 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.
