In 1970, Koss set the standard for full-size professional headphones with the iconic Pro/4AA. At the time of their introduction, the Pro/4AA were regarded as the first dynamic headphones to deliver true full frequency and high fidelity performance with impressive noise-isolating capabilities.
Retired in the late ’80s, Koss swiftly returned the Pro/4AA headphones to its product lineup due to overwhelming popular demand and have since remained a staple of studio headphones in the radio and recording industries.
There are many things listeners and audiophiles across the world still love about the Pro/4AA, but it was it's iconic 'Rhythm Beige' color that would start a trend as a celebrated colorway for future Koss Headphones.
In 1984 Koss released the iconic Porta Pro®. Since it's release Porta Pro® has set performance and comfort standards for personal listening worldwide and continues to be one of the most popular headphones today.
In 2017 Koss fans voted on five different concepts for a limited edition version of the Porta Pro®. After thousands of votes Koss would release a new version of it's Porta Pro® Classic in the same legendary Rhythm Beige colorway as the Pro4AA.
Fast forward to 2017, fourty-seven years after the introduction of the Pro/4AA, Koss announced their latest on-ear headphone to great fanfare the KPH30i.
KPH30i is a direct descendant of the Koss Pro35 and popular KTXPro1. With all-new modern features like an in-line microphone and remote, KPH30i keeps listeners connected all while enjoying their favorite tunes.
To celebrate the launch of it's newest headphone a special version of the KPH30i would be made available once more in iconic Rhythm Beige.
Koss would continue to evolve their headphone line-up, inventing new ways for listeners to connect to all of the modern devices they use like smartphones, tablets and laptops.
In 2022 this evolution would lead to three new headphones as part of the Koss Utility Series, and with it the all-new KPH40 Utility.
KPH40 Utility quickly became another celebrated Koss Headphone worldwide, and in late 2022 Koss would once again invite fans to vote on a new colorway.
After two weeks of voting a winner prevailed, and to no surprise Rhythm Beige would once again find it's way onto another legendary Koss Headphone.
Legendary headphones like the Pro/4AA, Porta Pro®, KPH30i and KPH40 Utility are not only celebrated worldwide for their high fidelity performance, comfort and industry leading innovations, but continue to be some of the most recognizable headphones around the world.
Their timeless design, acclaimed sound and iconic Rhythm Beige colorway is a testament to the vision founder John C. Koss had back in 1958 in creating the world's greatest headphones - a vision that now spans over 60 years of ingenuity, integrity, innovation and icons.
