Koss Porta Pro On-Ear Headphones with Retro Style, Collapsible Design, and Case

The Original American Stereophone Company, founded by John C. Koss in 1958, revolutionized the way people experience music with the invention of the world's first SP/3 stereophone. The goal was to capture the excitement of a live musical performance and bring listeners closer to the music they love. This dedication to accuracy in sound reproduction is evident in the Sound of Koss Porta Pro Collection.

The brand offers various products, including Retro Headphones, Utility Series, Wireless Headphones, and best sellers. The journey of Koss's innovation began with the development of a portable stereo photograph player in 1958, which led to the invention of the world's first SP/3 Stereophone. This was followed by the release of SP/3X, Pro/4AA, HV/1A, and the acclaimed Porta Pro in 1984.

Koss continued to innovate in wireless technology by introducing the JCK/300 Kordless System in 1989 and the breakthrough high-fidelity sound of the ESP/950 electrostatic headphones in 1990. The brand carries on the legacy of its Pro/4 line with the 2014 release of the Pro4S Studio Headphone.

The KPH30i, released in 2017, featured an ultra-lightweight design with remarkable high-fidelity sound. In 2021, Koss introduced its Utility Series with three new headphones that connect via Lightning, USB-C, and 3.5mm. Continuing its evolution of wireless headphones, Koss launched the TWS250i True Wireless Earbuds in 2023.

The Porta Pro, introduced in 1984 and unchanged for over 40 years, is known for its legendary design, high-fidelity audio, collapsible design, durability, and comfort. The Porta Pro Black offers a modern look with a retro soul, while the Porta Pro Classic remains true to the original design. Both versions deliver remarkable high-fidelity audio and comfortable listening experience.

The Porta Pro Black, Porta Pro Limited Edition, and other Koss products have received positive customer reviews due to their performance, comfort, and affordable prices. With a variety of options to choose from, Koss continues to be a leader in headphones and audio technology.
